NextEra Battery Storage Contracts Rise as US Power Demand Accelerates

NextEra Energy

NextEra battery storage contracts increased in the first quarter as the US utility group added 1.3GW of battery storage-based agreements. The additions formed part of 4GW of renewable and storage originations, alongside 2.2GW of solar and 0.5GW of wind.

NextEra battery storage contracts are rising because US electricity demand is growing faster and customers need capacity that can be deployed quickly. The company said demand for power is not slowing and that speed to power has become essential.

NextEra battery storage contracts also show how storage is becoming a core grid resource, not only a supplement to solar and wind. Battery systems can support peak demand, improve grid reliability and provide flexible capacity as data centres, electrification and industrial load growth increase pressure on power networks.

The company added more battery storage than in the first quarter of 2025, when it originated 0.9GW of storage within 3.2GW of renewable energy and storage capacity.

Storage Pipeline Supports Fast Grid Capacity Growth

NextEra has identified four main growth routes for battery storage. These include standalone projects, co-located storage at existing renewable sites, storage as a grid solution and expansion of existing projects from four-hour to eight-hour duration.

This is important because storage demand is becoming more diverse. Standalone batteries can provide rapid capacity support, while co-located systems can improve the value of solar and wind generation.

Longer-duration battery expansion is also strategically relevant. Moving from four-hour to eight-hour systems can help utilities manage evening demand peaks, renewable intermittency and grid congestion.

NextEra’s standalone and co-located storage pipeline exceeds 110GW, excluding expansion opportunities. That scale gives the company one of the strongest platforms in the US storage market.

The growth reflects a broader shift in power infrastructure. Utilities and large customers increasingly need fast capacity additions because new gas plants, transmission lines and conventional generation projects often face long development timelines.

Battery storage is not a full replacement for all forms of generation. But it is becoming one of the fastest tools available to respond to near-term power demand growth.

Secured Supply Through 2029 Reduces Execution Risk

NextEra said it has secured domestic supply for solar panels and battery storage through 2029 at competitive prices. This reduces exposure to trade disruption, tariff changes and equipment shortages.

Supply security matters because battery storage projects depend on reliable access to cells, modules, inverters, power conversion systems, transformers and grid interconnection equipment.

South Korean battery manufacturer Samsung SDI signed a deal in March 2025 to supply 6.3GWh of battery energy storage systems to NextEra. That agreement supports the company’s ability to execute projects while demand rises.

For battery materials, the growth of utility-scale storage strengthens demand for lithium, graphite, iron phosphate cathode materials, copper, aluminium and power electronics. LFP batteries are especially important in stationary storage because of cost, safety and cycle-life advantages.

NextEra’s first-quarter profit rose to $2.18bn on sales of $6.7bn, up from $833mn in profit and $6.25bn in sales a year earlier. Stronger financial performance gives the company more room to support its renewables and storage buildout.

The industrial significance is clear. Battery storage is becoming a strategic capacity product for the US power system, especially as electricity demand from data centres, manufacturing and electrification continues to rise.

The Metalnomist Commentary

NextEra’s storage growth shows that batteries are becoming part of the core power infrastructure toolkit. The next constraint will not be customer demand, but whether supply chains, interconnection queues and grid equipment can keep pace.

GM Redwood Battery Storage Project Extends EV Battery Value Chain

BESS

GM Redwood battery storage project will deploy repurposed electric vehicle battery packs at a General Motors plant in Michigan, extending the useful life of batteries before final recycling.

GM Redwood battery storage project will combine 100 reused EV battery packs into a 1.5MW/7.2MWh battery energy storage system. The installation will provide dispatchable power and help reduce electricity costs at the manufacturing site.

GM Redwood battery storage project is significant because it connects battery manufacturing, vehicle use, second-life energy storage and materials recovery within one supply chain. Redwood estimates the system will save more than $3mn in electricity costs over its operating life.

The project also shows how retired EV batteries can remain economically valuable even after they no longer meet automotive performance requirements.

Second-Life Batteries Add Value Before Recycling

EV batteries typically retain significant usable capacity when they are removed from vehicles. That remaining energy storage capability can support stationary applications where weight and space are less restrictive than in automotive use.

Repurposing packs for BESS applications can therefore delay recycling while extracting additional economic value from the battery.

For industrial facilities, storage systems can help manage peak electricity demand, provide backup power and shift energy consumption toward lower-cost periods.

The Michigan installation gives GM a direct opportunity to reduce plant electricity costs using batteries already linked to its own vehicle ecosystem.

This model also reduces the need for newly manufactured cells in some stationary storage applications. That can lower incremental demand for lithium, nickel, cobalt, graphite and other battery materials.

However, second-life systems still require testing, battery management and safety controls because used packs can have different degradation histories and performance characteristics.

Redwood Builds Closed-Loop Battery Supply Chain With GM

Redwood's relationship with GM extends across multiple stages of the battery lifecycle. The recycler handles manufacturing scrap, end-of-life EV packs and now second-life energy storage deployment.

Redwood has already received more than 28,000t of material from GM, with another 10,000 EV battery packs expected to enter the pipeline.

The company also works with Ultium Cells, GM's joint venture with LG Energy Solution, to recycle battery production scrap from facilities in Ohio and Tennessee.

This creates a more integrated materials loop. Manufacturing scrap can return quickly to recycling, while vehicle batteries can first enter stationary storage before eventually being processed for material recovery.

The approach could become increasingly important as EV battery volumes grow. Recycling alone captures raw materials, but second-life deployment can add another revenue stage before final recovery.

For automakers, that can improve battery economics while strengthening access to recycled lithium, nickel, cobalt and copper over the longer term.

The Metalnomist Commentary

GM and Redwood are showing that the battery circular economy does not begin with recycling. Second-life storage can create an additional commercial stage between vehicle use and materials recovery, improving both battery economics and supply-chain efficiency.

US Turkey LFP Battery Partnership Targets 7GWh Production by 2027

Our Next Energy

US Turkey LFP battery partnership emerged as Our Next Energy (ONE) contracted Turkish manufacturer Pomega Energy Storage Technologies to produce 7GWh of lithium iron phosphate battery cells. The strategic US Turkey LFP battery collaboration targets 2GWh production in 2026 escalating to 5GWh in 2027, supporting ONE's energy storage solutions for utility, commercial, and industrial customers while bridging manufacturing capacity before domestic US production commences.

Strategic Manufacturing Timeline Bridges International and Domestic Production

US Turkey LFP battery production will focus on ONE's 314Ah LFP battery cells manufactured at Pomega's Ankara facility. The Turkish facility maintains 3GWh installed capacity and currently undergoes qualification for global export markets. This partnership provides immediate manufacturing access while ONE develops its Michigan-based grid battery production line scheduled for 2027 operations.

Meanwhile, the collaboration enables ONE to meet near-term customer demands without delayed market entry. Founder and CEO Mujeeb Ijaz emphasized the partnership's role in supporting customer commitments during the transition to US-based manufacturing capabilities. The phased approach reduces market risks while ensuring continuous supply chain operations across international and domestic facilities.

Turkish Manufacturing Hub Supports Global Battery Supply Chains

However, Pomega's Ankara facility represents Turkey's growing position in global battery manufacturing ecosystems. The facility's 3GWh capacity and export qualification process demonstrate Turkish manufacturing capabilities in advanced energy storage technologies. Turkey's strategic geographic position provides advantageous access to European, Middle Eastern, and Asian markets for battery exports.

Therefore, the partnership leverages Turkey's industrial infrastructure while supporting ONE's expansion strategy across utility-scale energy storage markets. Turkish manufacturing costs and skilled workforce availability create competitive advantages for large-scale battery production. The collaboration also strengthens US-Turkey commercial relationships in critical technology sectors driving clean energy transitions.

Market Positioning for Utility-Scale Energy Storage Growth

Furthermore, the LFP battery production targets utility, commercial, and industrial energy storage applications experiencing rapid market expansion. Lithium iron phosphate technology offers safety and cost advantages compared to alternative battery chemistries, particularly for large-scale stationary storage installations. The 314Ah cell specification aligns with industry requirements for grid-scale energy storage systems.

As a result, ONE's dual-facility strategy positions the company competitively across North American and international markets during the critical 2026-2027 period. The Turkish production capacity provides flexibility while Michigan facility development progresses, ensuring market presence during peak demand growth. This geographic diversification reduces supply chain risks while maximizing market opportunities across multiple regions.

The Metalnomist Commentary

ONE's partnership with Turkish manufacturer Pomega exemplifies how US battery companies strategically leverage international manufacturing partnerships to bridge capacity gaps before domestic production scaling, particularly important as global LFP demand accelerates faster than domestic manufacturing development. The collaboration demonstrates Turkey's emerging role as a strategic manufacturing hub for critical battery technologies, positioning the country advantageously within global energy storage supply chains serving both European and American markets.

Ford Energy BESS Deal With EDF Signals Automaker Push Into Grid Storage

Ford Energy

Ford Energy BESS deal with EDF Power Solutions North America marks a major step in Ford’s move from vehicle batteries into grid-scale energy storage. Ford Energy will supply EDF with 20GWh of battery energy storage systems over five years starting in 2028.

Ford Energy BESS deal gives EDF access to up to 4GWh/yr of DC block systems for utility-scale storage projects across the US. The agreement positions Ford Energy as a key domestic supplier for large energy storage developers.

Ford Energy BESS deal also shows how automakers are repurposing battery manufacturing assets for stationary storage. Ford is investing $2bn to convert its Glendale, Kentucky, battery facility for the BESS market.

The transaction connects three fast-growing demand drivers: grid storage, data centers and US-made battery systems. It also reinforces the strategic role of lithium iron phosphate batteries in stationary applications.

LFP Storage Supports Utilities, Data Centers and Industrial Customers

Ford Energy’s DC Block is a standardized 20ft containerized battery energy storage system. Each unit has 5.45MWh of capacity and uses lithium iron phosphate prismatic cells.

The system is available in two-hour and four-hour discharge configurations. That flexibility allows EDF to deploy storage across different grid services, renewable integration and peak-shifting applications.

LFP batteries are well suited to stationary storage because they offer cost advantages, safety benefits and long cycle life. They also reduce exposure to nickel and cobalt compared with higher-nickel lithium-ion chemistries.

Ford Energy plans to assemble BESS in the US for utilities, data centers, large industrial customers and commercial users. That customer mix reflects how electricity demand is changing.

Data centers are becoming a major new source of power demand. Battery storage can help manage grid congestion, renewable intermittency and backup power requirements.

EDF already has a large platform for deployment. The company has developed 26GW of projects and holds 17GW under service contracts, giving Ford Energy a major channel into the US storage market.

Repurposed Battery Capacity Strengthens US Storage Supply Chain

Ford Energy plans to deploy at least 20GWh/yr of BESS capacity, with first customer deliveries scheduled for late 2027. The EDF agreement will absorb a meaningful share of early output from 2028.

The Glendale investment is strategically important. It shows how battery manufacturing capacity originally linked to vehicle electrification can be redirected toward stationary storage.

This matters because EV demand growth has become less linear, while grid storage demand continues to rise. Automakers with battery manufacturing assets may find BESS a valuable second market.

The deal also strengthens the US energy storage supply chain. Domestic assembly can reduce logistics risk, support local content requirements and improve delivery certainty for infrastructure customers.

For battery materials, the agreement supports demand for lithium, phosphate, graphite, copper, aluminium and battery-grade chemicals tied to LFP cells and storage systems.

The wider implication is clear. Battery demand is no longer only an EV story. Utilities, data centers and industrial customers are becoming major buyers of battery systems as power reliability becomes a strategic constraint.

The Metalnomist Commentary

Ford’s EDF agreement shows that stationary storage is becoming a major outlet for battery manufacturing capacity. The strategic winners will be companies that can combine US assembly, LFP chemistry and long-term supply agreements with grid and data-center customers.

Adani Green BESS Expansion Makes Khavda a Major Grid Storage Platform

Adani Green Energy

Adani Green BESS capacity has reached 3.37GWh at the Khavda renewable energy park in Gujarat, marking a major step in India’s effort to make large-scale renewable power more reliable and dispatchable. Adani Green Energy added 2GWh to the 1.37GWh installed in March.

Adani Green BESS development at Khavda is significant because the project is now the largest single-location battery storage installation outside China, according to the company. The system is co-located with AGEL’s 30GW renewable energy project, of which 9.9GW is already operational.

Adani Green BESS expansion also signals how India’s clean energy transition is moving beyond generation capacity alone. Solar and wind projects need storage to manage intermittency, stabilise grids and supply power during peak demand periods.

The company plans to scale its storage footprint quickly. It is targeting more than 10GWh of new capacity by March 2027 and aims to reach 50GWh over the next five years.

Khavda Storage Strengthens Renewable Power Dispatchability

The Khavda BESS uses lithium-ion battery technology integrated with advanced energy management systems. This allows faster grid response, better stability and more reliable renewable power delivery.

This matters because India is adding renewable power at scale, but grid flexibility remains a major constraint. Battery storage helps convert variable solar and wind generation into usable power during high-demand periods.

AGEL said the 3.37GWh system can power about 1mn homes for a full day. It can also meet peak electricity demand in cities such as Indore or Chandigarh, or supply the entire state of Goa.

The Khavda project therefore shows how battery storage is becoming core electricity infrastructure. It is no longer only a backup tool or pilot technology.

For India, this type of storage capacity supports energy security, renewable integration and reduced dependence on fossil fuel peaking power. It also strengthens the case for more domestic battery materials, cell manufacturing and power electronics capacity.

Battery Storage Growth Lifts Materials and Supply-Chain Demand

Large BESS projects create demand across several material chains. Lithium-ion batteries require lithium, graphite, copper, aluminium, separators, electrolytes, battery management systems and thermal control technologies.

Copper demand is also supported by cabling, grid connections, transformers and power conversion systems. Aluminium can benefit through enclosures, busbars, structural systems and cooling components.

India’s rapid storage targets could therefore deepen demand for battery raw materials and downstream manufacturing. The country will need reliable supply chains for cells, modules, inverters and grid equipment if it wants to scale from gigawatt-hours to tens of gigawatt-hours.

The Khavda system also highlights the strategic link between renewable energy and industrial policy. Battery storage deployment can create demand signals for local manufacturing, recycling and critical minerals processing.

However, scaling to 50GWh will require capital, land, grid integration, battery procurement and long-term project economics. Storage must become not only technically viable, but also financially repeatable.

Adani Green’s commissioning shows that India is moving quickly. The next challenge is building a domestic ecosystem that can support storage deployment without relying too heavily on imported battery materials and equipment.

The Metalnomist Commentary

Khavda shows that the renewable energy race is becoming a storage race. India’s next clean-energy bottleneck will not be only solar or wind capacity, but the battery materials, grid equipment and financing needed to make renewable power dispatchable.

Western Australia Vanadium Battery Plan Targets Grid Storage and Local Supply Chain

Vanadium Battery

Western Australia vanadium battery plans are moving forward as the state government offers A$150mn to support a 50MW battery energy storage system in Kalgoorlie. The project is intended to strengthen energy security in Kalgoorlie and the Eastern Goldfields as the state exits coal-fired power.

Western Australia vanadium battery funding will be awarded through a competitive proposal process. Bids are due by 20 July 2026, with evaluation expected from July and results to be announced later in the year.

Western Australia vanadium battery proposals must also show how they will support the local vanadium supply chain. That condition gives the project industrial significance beyond electricity storage alone.

The plan connects grid reliability, renewable integration and critical minerals development. It also supports Western Australia’s wider Made in WA policy, which aims to build more local manufacturing and clean-energy supply chain capacity.

Kalgoorlie Storage Project Supports Coal Exit

The 50MW Kalgoorlie project is part of Western Australia’s transition away from state-owned coal-fired generation. The government pledged in 2022 to close all state-owned coal plants by 2030.

Several major coal units are already scheduled for closure. Synergy’s Muja C, Muja D and Collie power station will be retired in stages between 2025-26 and 2029-30.

Battery storage is expected to replace part of the capacity and flexibility lost from coal. This is critical because renewable generation requires storage assets that can manage intermittency, stabilise the grid and support peak demand.

Kalgoorlie and the Eastern Goldfields are particularly important because mining regions need reliable electricity. Power disruptions can affect processing plants, mine operations, logistics and regional industrial development.

The government expects more than 1,200MW of new generation and storage to enter the South West Interconnected System in 2025-26 and 2026-27. A further 1,000MW is expected in 2027-28.

The scale of the pipeline shows that Western Australia is not treating storage as a marginal add-on. It is becoming core infrastructure for the state’s post-coal power system.

Vanadium Supply Chain Becomes Part of Energy Policy

The request for proposals is notable because it links battery deployment with local vanadium supply chain investment. This turns the project into both an energy storage initiative and a critical minerals development tool.

Vanadium batteries are attractive for long-duration grid storage because they can offer long cycle life and are suited to stationary applications. They do not compete directly with lithium-ion batteries in every market, but they can serve grid use cases where durability and duration matter.

Western Australia has already invested heavily in battery storage. In 2023, the state awarded A$1bn to support the 500MW Collie battery energy storage system and the 200MW Kwinana battery energy storage system.

The state’s 2025-26 budget also included A$50mn for a local battery manufacturing programme under the Made in WA policy. That aligns with the new vanadium battery proposal, which asks bidders to contribute to regional, economic and community outcomes.

Federal support is also backing Western Australia’s storage buildout. Four lithium-ion battery projects are being partly underwritten through the Capacity Investment Scheme, adding 2.6GWh of storage capacity from late 2027.

This creates a mixed battery landscape. Lithium-ion will remain important for large-scale storage, but vanadium could give Western Australia a route to build a differentiated local supply chain around its own mineral base.

The strategic test will be whether the Kalgoorlie project can move beyond demonstration value. It must prove cost competitiveness, operational reliability and real local supply chain development.

The Metalnomist Commentary

Western Australia is using grid storage procurement to create demand for a local vanadium industry. That is the right industrial logic: critical mineral supply chains need committed end-use demand, not just resource potential.

Rivian Second-Life Battery Storage Project Links EV Packs to Grid Reliability

Rivian, Redwood

Rivian second-life battery storage is moving into commercial use after the US electric-vehicle maker agreed to deploy repurposed battery packs through Redwood Materials at its Normal manufacturing plant in Illinois. The project will use more than 100 used Rivian battery packs to provide 10 MWh of dispatchable battery energy storage.

The Rivian second-life battery storage project gives retired EV packs a second use before recycling. Redwood Materials will integrate the packs into a Redwood Energy system for on-site use at Rivian’s manufacturing facility.

Rivian second-life battery storage also reflects a wider shift in the battery value chain. Automakers and recyclers are looking for ways to extract more value from battery packs before recovering lithium, nickel, cobalt, copper, aluminium and other materials.

Redwood Turns Used EV Packs Into Stationary Storage

Redwood will receive EV battery packs from Rivian and convert them into a battery energy storage system for the Normal plant. The system will help reduce energy costs and support local grid reliability.

Second-life batteries are useful because EV packs can still retain meaningful capacity after vehicle use. They may no longer meet automotive performance requirements, but they can still serve stationary storage applications.

This creates a bridge between mobility and grid infrastructure. A battery pack can first support vehicle electrification, then provide stationary power, and later enter recycling for critical material recovery.

Redwood receives more than 20 GWh/yr of batteries, giving it a large feedstock base for both reuse and recycling. The company said it can deploy BESS projects in as little as six months, which matters as power demand rises quickly.

Data Center Power Demand Raises Storage Value

Rivian has attracted investors such as Google, which are seeking faster access to power solutions for artificial intelligence data center growth. This connection shows why second-life batteries are becoming more strategically relevant.

AI data centers need reliable, flexible and rapidly deployable power. Battery energy storage systems can help manage peak demand, improve resilience and reduce pressure on grids facing new large-load connections.

Repurposed EV batteries could become a lower-cost option where speed matters more than maximum energy density. They may also reduce waste and delay the need for immediate material recycling.

For the metals supply chain, this creates a more circular model. Battery materials stay in productive use longer, while recyclers build stronger long-term access to end-of-life packs and future recovered metals.

The Metalnomist Commentary

Rivian and Redwood are showing how EV batteries can become grid assets before they become recycling feedstock. The strategic value lies in extending battery life, lowering storage costs and securing future material recovery in one integrated loop.

UCB Power BESS Production Gains Tax Support in Brazil

UCB Power

UCB Power BESS production will receive tax support as Brazil seeks to expand domestic manufacturing of battery energy storage systems. The Brazilian battery producer will benefit from reduced import tariffs on foreign components used in production.

UCB Power BESS production adds another industrial layer to Brazil’s growing energy storage market. The incentives will be administered through the Manaus Free Trade Zone framework, although specific tariff reductions have not been disclosed.

UCB Power BESS production also has implications for critical mineral demand. Lithium-ion storage systems require materials including lithium, nickel, cobalt, manganese, graphite, copper and aluminium across cells, electrical systems and enclosures.

The policy therefore supports more than battery assembly. It could help Brazil gradually build a domestic energy storage ecosystem around renewable power, grids and industrial electricity management.

Tax Incentives Strengthen Domestic Battery Manufacturing

Brazil’s Manaus Free Trade Zone provides tax incentives intended to encourage industrial production in the country’s northern region.

UCB Power will gain lower import costs for foreign components required in BESS manufacturing. This can improve the competitiveness of domestic production while Brazil develops more local supply capability.

The incentives remain subject to standard requirements within the Manaus framework, including environmental and research obligations.

Battery storage manufacturing remains dependent on imported cells, materials and electronic components in many emerging markets. Lower tariffs can therefore reduce the cost disadvantage faced by local manufacturers during the early stages of industry development.

UCB already operates battery factories in Manaus and Extrema, Minas Gerais. The company says its portfolio represents more than 7.8GWh of installed capacity.

That existing manufacturing base gives UCB a stronger position to expand into grid-scale and industrial energy storage as Brazilian electricity demand evolves.

BESS Growth Could Create New Critical Mineral Demand

Battery energy storage is becoming increasingly important as power systems integrate more intermittent renewable generation.

BESS installations can store electricity when supply is abundant and discharge it when demand rises, improving grid flexibility and helping industrial users manage electricity costs.

Lithium-ion technology currently dominates the market, creating demand across a broad range of battery materials.

For Brazil, this creates an opportunity to connect domestic battery manufacturing with its substantial mineral resource base. The country has resources across lithium, nickel, manganese and other materials relevant to energy storage.

However, mineral availability alone will not create an integrated battery industry. Brazil will need refining, active materials production, cell manufacturing and recycling capacity if it wants to capture more of the value chain.

Supporting BESS assembly is therefore an early step toward a broader industrial ecosystem rather than the endpoint.

The Metalnomist Commentary

Brazil has the mineral resources and renewable power base to build a larger battery industry, but the missing link remains downstream processing and cell production. UCB’s expansion can help create domestic demand that makes those investments more commercially attractive.

SoftBank Osaka Battery Production Targets AI Data Centre Energy Demand

SoftBank

SoftBank Osaka battery production plans will add a new Japanese platform for next-generation battery cells and battery energy storage systems. The company aims to start production at its GX Factory in Osaka by March 2028.

SoftBank Osaka battery production will focus partly on zinc-halogen battery technology developed with South Korea’s COSMOS Lab. The partners aim to begin mass production during the April 2027-March 2028 fiscal year.

SoftBank Osaka battery production is strategically linked to rising electricity demand from artificial intelligence infrastructure. As AI data centres expand, operators need safer, scalable and more resilient energy storage systems to support grid stability and power management.

The GX Factory is part of SoftBank’s planned AI data centre development at Sakai in Osaka prefecture, on a site formerly owned by Sharp. The wider project also includes the AX Factory, which will focus on AI data centre operations and infrastructure hardware manufacturing.

Zinc-Halogen Technology Targets Safety and Local Supply

SoftBank is positioning zinc-halogen batteries as a safer alternative to lithium-ion systems. The company said the technology removes lithium-ion fire risk by using a halogen-based cathode material, zinc anode and water-based electrolyte.

This chemistry also supports supply-chain resilience. Zinc and halides are available in Japan, reducing exposure to imported lithium, nickel, cobalt or graphite supply chains.

That matters because energy storage is becoming more strategically important as AI data centres, renewable power and grid balancing needs grow together. Battery systems must be safe, affordable and scalable.

Zinc-halogen batteries may be especially relevant for stationary storage, where safety, durability and material availability can matter more than maximum energy density.

SoftBank’s plan shows that AI infrastructure is beginning to shape battery demand beyond electric vehicles. Data centres require large and reliable power systems, and that could create a new demand channel for non-lithium battery chemistries.

BESS Manufacturing Adds Industrial Scale Ambition

SoftBank will also partner with South Korea’s DeltaX to develop and manufacture high-energy-density battery energy storage systems. The partnership will use DeltaX’s cell-connecting system design and cell-to-pack technology.

SoftBank aims to reach 1 GWh/yr of BESS mass production by the 2028-29 fiscal year. That would give the company a meaningful platform for grid, industrial and data-centre storage customers.

The company plans to expand sales into grid-storage, industrial and residential applications. It is also considering overseas markets in the medium term.

SoftBank wants the battery business to generate more than ¥100bn in annual revenue by the 2030-31 fiscal year. That target shows the company sees batteries as an infrastructure business, not only a technology experiment.

For Japan, the project strengthens domestic battery manufacturing around AI infrastructure and energy security. It also diversifies battery chemistry development beyond the lithium-ion supply chain.

The industrial implication is clear. As AI power demand accelerates, battery storage will become a strategic layer between data centres, grids and renewable energy supply.

The Metalnomist Commentary

SoftBank’s Osaka plan shows that AI infrastructure is now pulling battery innovation in a new direction. Zinc-halogen technology may not replace lithium-ion in vehicles, but it could become strategically important for safer, locally sourced stationary storage.

Stellantis NextStar Battery JV Exit Signals a New Shift in North American Battery Strategy

NextStar Battery

Stellantis NextStar battery JV exit marks another important shift in North American battery strategy. Stellantis will sell its 49pc stake in NextStar Energy to LG Energy Solution. The joint venture built Canada’s first large-scale lithium-ion battery plant in Windsor, Ontario. As a result, Stellantis NextStar battery JV exit shows that automakers are rethinking how they participate in battery manufacturing.

This move matters because NextStar was a major industrial project. Stellantis and LG Energy Solution invested more than C$5bn in the venture. Yet the ownership structure is now changing even as the plant remains strategically important. Therefore, Stellantis NextStar battery JV exit is not a retreat from batteries. It is a shift in how the company wants to access them.

Stellantis will remain a customer of the facility after the transaction. That means the company still wants battery supply, but no longer wants to own nearly half of the manufacturing platform. Consequently, Stellantis NextStar battery JV exit reflects a broader trend toward supply access without full operating exposure.

EV Battery Joint Ventures Are Moving Into a New Phase

EV battery joint ventures are no longer being treated as fixed long-term ownership models. Automakers are increasingly separating battery access from battery plant ownership. That change is becoming visible across North America. As a result, EV battery joint ventures are entering a more flexible and less traditional phase.

The Stellantis decision fits a wider pattern. Other major automakers have also restructured or exited battery partnerships. General Motors sold its Michigan battery JV stake to LG Energy Solution in 2025. Ford also changed the structure of its BlueOval SK partnership later that year. Therefore, Stellantis NextStar battery JV exit looks less like an isolated deal and more like an industry reset.

This shift likely reflects changing economics and strategy. Battery manufacturing is capital-intensive, operationally complex, and increasingly competitive. Automakers may now prefer to secure output through commercial agreements while leaving plant ownership and operation to battery specialists. Meanwhile, battery makers can broaden their customer base more easily under that structure.

North American Battery Strategy Is Becoming More Specialized

North American battery strategy is now moving toward clearer specialization between automakers and cell producers. After the ownership change, NextStar will serve a broader customer base, including the energy storage system sector. That gives the plant more flexibility than a single-customer automotive model. As a result, the facility may become commercially stronger even as Stellantis reduces direct ownership.

This matters because battery plants are no longer only tied to electric vehicle demand. Energy storage systems are becoming a second major growth market. A battery facility that can sell into both EVs and stationary storage may have better long-term utilization and lower concentration risk. Therefore, North American battery strategy is becoming more diversified at the customer level.

The broader lesson is clear. Automakers still need batteries, but they may not want to carry the same level of manufacturing ownership risk as before. Battery producers, meanwhile, can gain more control and expand into wider end markets. Consequently, Stellantis NextStar battery JV exit may signal a more mature phase in the North American battery buildout.

The Metalnomist Commentary

This deal matters because it shows the battery race is no longer only about building plants. It is now about deciding who should own them, run them, and absorb the risk. Stellantis still wants battery supply, but LGES now looks better positioned to turn NextStar into a broader industrial platform.

Global Energy Storage Market Expands as China Drives Record Growth

China Energy Storage

Global energy storage market growth accelerated in 2025, with China remaining the main force behind new capacity additions and technology diversification. The country’s cumulative operating power storage capacity reached 213.3GW by the end of the year, accounting for 43% of the global total.

China energy storage growth was especially strong in new-type energy storage, which includes lithium-ion batteries and vanadium redox flow batteries but excludes pumped hydro. China’s new-type storage capacity rose to 144.7GW, representing more than two-thirds of its total storage fleet and 51.9% of global new-type installations.

The global energy storage market also became more diversified. Pumped hydro’s share of global operating capacity fell below 50% for the first time, while new-type storage expanded rapidly to 278.7GW/687.5GWh.

China Leads Storage Deployment as VRFB Projects Gain Share

China’s energy storage sector remained dominated by lithium-ion batteries in 2025. However, lithium-ion’s share slipped slightly as several large long-duration storage projects using all-vanadium redox flow battery technology came online.

This shift matters because grid storage demand is no longer only about short-duration battery systems. Longer-duration applications are gaining relevance as renewable penetration rises and power systems require more flexibility, peak shifting and grid stability.

Independent energy storage became China’s main application model, accounting for around 60% of total installed capacity. This shows that storage is increasingly being deployed as standalone grid infrastructure, not only as an accessory to solar or wind projects.

Chinese manufacturers also strengthened their global position. Sungrow, Tesla, CRRC Zhuzhou Institute, BYD and Envision Energy ranked as the world’s top five energy storage system shipment providers in 2025, highlighting the growing concentration of supply among large integrated players.

Lithium Demand Rises as Storage Becomes a Core Battery Market

The global energy storage market reached 496.2GW of cumulative operating power storage capacity by the end of 2025, up 33.3% from the previous year. New installations hit a record 123.9GW, led by China, the US and Europe, while the Middle East and Latin America gained momentum.

The US added 18.4GW/48.3GWh of new-type storage capacity in 2025, while Europe added 15.4GW/32.1GWh. These figures show that storage growth is becoming global, even though China remains the dominant scale market.

Energy storage is also reshaping battery materials demand. The sector accounted for 25% of global lithium demand in 2025, up sharply from 5% in 2020, making storage one of the most important demand drivers for lithium carbonate, lithium iron phosphate materials and battery supply chains.

Stronger storage demand helped push battery-grade lithium carbonate prices to 158,000-168,000 yuan/t at the end of March, up 120% from a year earlier. This confirms that stationary storage has moved from a secondary battery market into a major force in lithium pricing.

The Metalnomist Commentary

China’s dominance in energy storage shows how quickly battery supply chains can scale when policy, manufacturing and grid demand align. The next phase will test whether lithium, vanadium and power equipment supply can keep pace with global storage deployment.

XFH Anode Material Sales Rise as China Battery Demand Expands

Anode Material

XFH anode material sales increased in 2025 as demand from China’s lithium-ion power battery and energy storage battery industries continued to grow. Shanghai XFH Technology sold 83,885t of anode materials during the year, up 22% from 2024.

XFH anode material sales outpaced production growth, showing stronger downstream offtake from battery manufacturers. The company’s anode material output rose by 11% on the year to 83,426t.

XFH anode material sales also lifted revenue. The company’s anode material revenue rose by 21% to 1.7bn yuan, supported by higher shipment volumes into battery supply chains.

The result reflects continued expansion in China’s battery ecosystem. Power battery shipments exceeded 1,000GWh in 2025, up by more than 50% from a year earlier, while energy storage battery shipments rose by 85% to 630GWh.

Suining Complex Expands XFH’s Anode Capacity

XFH increased anode material production capacity to 114,660 t/yr in 2025, up 27% from the previous year. The increase followed the production launch of its 60,000 t/yr complex in Suining, Sichuan province, at the end of 2025.

The new capacity gives XFH more room to serve fast-growing battery demand. Anode materials are a core input for lithium-ion batteries, influencing charging performance, cycle life, safety and energy density.

China’s rapid growth in power batteries and storage batteries is driving expansion across the anode supply chain. Producers are adding capacity to meet demand from electric vehicles, grid storage, industrial storage systems and consumer battery applications.

The Suining project also strengthens XFH’s position in a market where scale, cost control and customer qualification are critical. Larger capacity can improve operating efficiency, but it also requires stable demand to avoid inventory and pricing pressure.

Energy Storage Growth Supports Anode Demand

Energy storage is becoming an increasingly important driver for China anode materials. Storage battery shipments grew faster than power batteries in 2025, rising by 85% from a year earlier.

This matters because energy storage systems require large volumes of battery materials even when they have different performance priorities from electric vehicles. Cost, cycle life, safety and supply reliability are especially important in storage applications.

Power battery demand remains the largest driver. China’s battery shipments above 1,000GWh show the scale of the domestic EV and battery manufacturing base.

For anode producers, the opportunity is large but competitive. Demand growth supports shipments, but capacity expansion across China can still create margin pressure if supply grows faster than customer orders.

XFH’s stronger sales and output show that qualified anode producers remain tied closely to downstream battery expansion. The next challenge will be maintaining utilisation and profitability as China’s battery materials sector continues to scale.

The Metalnomist Commentary

XFH’s growth shows that China’s battery materials chain is still expanding quickly, especially in anodes. However, rising capacity means producers must compete on qualification, cost and customer access, not only shipment growth.

Samsung SDI BESS Supply Deal Strengthens US Energy Storage Battery Chain

Samsung SDI BESS

Samsung SDI BESS supply deal activity is accelerating in the US as demand for grid-scale battery storage continues to rise. The South Korean battery manufacturer has secured a 1.5 trillion won, or about $1 billion, contract to supply BESS batteries to a US energy company over four years.

The Samsung SDI BESS supply deal will run from 2026 to 2029. The batteries will be supplied in phases, supporting the rapid buildout of US battery energy storage systems as utilities, renewable developers, and infrastructure operators seek more flexible power capacity.

The agreement also strengthens Samsung SDI’s US manufacturing strategy. The batteries will be produced at StarPlus Energy’s plant in Indiana, a joint venture between Samsung SDI and Stellantis.

Indiana Production Links Battery Storage to Domestic Manufacturing

The StarPlus Energy facility gives Samsung SDI a local production base for the US energy storage market. This matters because US customers increasingly value domestic or regionally anchored battery supply chains, especially for energy infrastructure projects.

Initial deliveries will use nickel-cobalt-aluminum batteries. This chemistry gives Samsung SDI a route to serve early BESS demand while preparing for broader chemistry diversification.

Later expansion will include lithium iron phosphate batteries. LFP batteries are becoming more important in stationary storage because cost, safety, cycle life, and scale matter more than maximum energy density in many grid applications.

LFP Expansion Signals a Wider Shift in US BESS Demand

The Samsung SDI BESS supply deal follows another major LFP agreement signed last December with an unnamed US energy infrastructure company. That earlier contract was valued at two trillion won, or about $1.33 billion.

Together, the deals show that Samsung SDI is moving more aggressively into the US battery energy storage systems market. The company is no longer positioned only around electric vehicle batteries, but also around grid storage and power infrastructure.

This shift has important materials implications. BESS growth will increase demand for lithium, iron phosphate materials, nickel, cobalt, aluminum, copper, graphite, separators, electrolytes, and power electronics. It will also intensify competition among Korean, Chinese, Japanese, and US-linked battery supply chains.

The Metalnomist Commentary

Samsung SDI’s latest contract confirms that US battery demand is shifting from EV-only growth toward a broader energy infrastructure cycle. For battery makers, chemistry flexibility and local production are becoming as important as scale itself.

Global Lithium-Ion Battery Shipments Surge in 2024, Driven by EV and Energy Storage Demand

Lithium-Ion Battery

Global shipments of lithium-ion batteries experienced a significant surge in 2024, fueled by robust growth in both the electric vehicle (EV) and energy storage sectors, according to data from Chinese research institution EV Tank.  This surge is projected to continue its upward trajectory through 2030, marking a promising period for the lithium and battery metals markets.

EV Battery Market Driven by China, Despite Global Economic Headwinds

In 2024, global EV power battery shipments reached an impressive 1,051GWh, representing a 22% year-on-year increase.  This growth was primarily propelled by the continued strength of China's EV market.  Government incentives, such as old vehicle trade-in subsidies, provided a significant boost, offsetting a slowdown observed in European and US markets due to weakened economic conditions and rising inflation.  This highlights the critical role of government policy in supporting the EV sector.

Energy Storage Battery Shipments See Explosive Growth

The energy storage battery segment also witnessed remarkable expansion, with global shipments soaring by 65% to 370GWh.  This surge can be attributed to several factors, including China's government-led initiatives promoting energy storage systems for wind and solar power generation, declining manufacturing costs, and strong demand in the US, partly driven by the investment tax credit.  Furthermore, growing GWh-level orders from emerging markets like the UK, Saudi Arabia, and Australia contributed to the overall growth.

China Dominates Lithium-Ion Battery Production

Overall, global lithium-ion battery shipments increased by 29% year-on-year to 1,545GWh in 2024.  China played a dominant role, accounting for 79% of the total, with shipments reaching 1,215GWh, a substantial 37% increase.  The sustained demand growth within China, coupled with the country's substantial investments in overseas production capacity, has solidified its position as a leading force in the global lithium-ion battery market.

Sodium-Ion Battery Adoption Slower Than Expected

While lithium-ion batteries continue to dominate, the adoption of sodium-ion batteries has been slower than initially anticipated.  EV Tank estimates China's sodium-ion battery shipments to have more than doubled to 2GWh in 2024 from 0.7GWh in 2023. However, this figure falls short of earlier projections of 3GWh per year. The primary reason for this slower uptake is the higher manufacturing costs associated with sodium-ion batteries compared to ternary and lithium iron phosphate (LFP) lithium-ion batteries, as well as lead-acid batteries.  Currently, the average manufacturing cost for lithium-ion batteries stands at 0.50 yuan/Wh as of June 2024, significantly lower than the 0.60 yuan/Wh for sodium-ion batteries, according to EV Tank.  This cost differential presents a significant challenge for the widespread adoption of sodium-ion technology.

Future Outlook: Continued Growth Projected

EV Tank forecasts continued growth in global lithium-ion battery shipments, projecting a rise to 1,899GWh in 2025 and an even more significant jump to 5,127GWh by 2030.  This optimistic outlook underscores the increasing demand for batteries across various applications, driven by the ongoing transition to electric mobility and the growing importance of energy storage solutions. The declining lithium carbonate feedstock prices, caused by supply expansions, have helped reduce manufacturing costs for lithium-ion batteries, further supporting market growth.

Tesla Launches Shanghai Megapack Energy Storage Battery Factory

Tesla

In an exciting move towards sustainability and the acceleration of global energy transition, Tesla has officially launched its Megapack energy storage battery gigafactory in Shanghai. This new facility is a significant step in Tesla’s efforts to expand its energy storage systems globally, marking its first production unit for energy storage outside the United States.

Gigafactory’s Vision and Production Capacity

The factory is located in the Lin-gang Special Area of China’s Shanghai Pilot Free Trade Zone, with a planned production capacity of 10,000 Megapack units per year. This capacity equates to 40 GWh of energy storage. Tesla produced its first Megapack unit in February 2024, and production is expected to ramp up in the first quarter of the year. The company’s expansion of Megapack manufacturing is crucial in meeting the growing demand for energy storage systems as part of global efforts to transition to renewable energy sources.

Innovative Megapack Technology and Tesla’s Global Impact

The Megapack, which was first launched in 2019, can store up to 3,900 kWh of electricity per unit. This capacity is equivalent to the energy storage needs of 62 Model 3 electric vehicles (EVs). Designed to serve as large-scale energy storage solutions, the Megapack is ideal for battery storage power stations and can help stabilize grids reliant on renewable energy sources. Tesla’s goal is not just to create electric vehicles but to be a key player in the global energy transition, producing innovative energy storage technologies that support renewable power generation.

Tesla’s Expansion in Global Energy Storage Systems

This Shanghai-based gigafactory is Tesla's first energy storage manufacturing facility outside of the United States. Tesla’s California factory, which started production earlier, has a capacity of 40 GWh per year, producing around 200 Megapack units weekly. With the Shanghai factory now operational, Tesla aims to scale its energy storage solutions globally, facilitating the transition to sustainable energy worldwide. The company also reported a significant 113% increase in energy storage capacity in 2024, reaching 31.4 million kWh, surpassing the total capacity of the past three years combined.

Tesla’s ambition is clear. As the company looks to meet the increasing demand for energy storage solutions, it highlights the potential for Megapacks to play a critical role in energy generation and storage. As Tesla notes, just 0.1% of China’s Taklimakan Desert could power the entire nation for a year with the energy stored in these systems.

Conclusion: A Global Energy Shift on the Horizon

Tesla’s commitment to scaling energy storage production marks a pivotal moment in the push towards renewable energy. With the Shanghai gigafactory now in full production, the company is well-positioned to meet the rising global demand for energy storage batteries. As shipments of energy storage systems continue to grow, Tesla's innovations promise to be a crucial component in the energy transition, helping to reduce reliance on fossil fuels and ensuring a more sustainable future.

Tesla LGES Michigan Battery Plant Strengthens US LFP Supply for Energy Storage

LGES, Michigan Battery Plant

Tesla LGES Michigan battery plant plans mark a major step in the buildout of US lithium iron phosphate battery capacity. Tesla and LG Energy Solution have signed a supply agreement to develop a $4.3 billion LFP battery cell facility in Lansing, Michigan.

The plant is scheduled to begin production in 2027. It will supply battery cells for Tesla’s Megapack 3 energy storage systems, which the company plans to produce at its Houston megafactory.

The Tesla LGES Michigan battery plant also reflects a wider shift in battery demand. Stationary energy storage is becoming a larger driver of cell procurement as power grids absorb more renewable energy, data center demand, and industrial electrification.

Lansing Facility Repositions Former EV Capacity Toward Grid Storage

The Lansing project carries strategic significance because the facility previously formed part of a General Motors and LGES joint venture. LGES acquired GM’s stake for $2.1 billion after GM reduced electric vehicle-related capacity and investment.

This change shows how battery assets can be redirected as market priorities shift. EV demand remains important, but utility-scale storage is becoming a stronger growth channel for LFP chemistry.

The 50 GWh per year facility gives Tesla a large domestic cell supply base for Megapack 3. It also supports Tesla’s plan to begin Megapack 3 and Megablock production in Houston in 2026.

LFP Chemistry Gains Ground in US Energy Storage Supply Chains

LFP battery cells are becoming increasingly important for energy storage systems because they offer cost, cycle life, and safety advantages for stationary applications. For Tesla, securing LFP supply in the US reduces exposure to imported cells and supports larger energy storage deployments.

The Tesla LGES Michigan battery plant also strengthens LGES’s position in the US battery value chain. By converting a former EV-focused site into a major LFP supply point, LGES can serve a market where demand is tied to grid infrastructure rather than only vehicle sales.

Tesla’s Megapack business is already scaling. The company sold $430 million of Megapack products in 2025 to xAI, its sister company and Elon Musk’s artificial intelligence startup, highlighting the link between energy storage and rising power demand from AI infrastructure.

The Metalnomist Commentary

This agreement shows that battery supply chains are no longer being shaped only by electric vehicles. Grid storage, AI power demand, and domestic manufacturing policy are becoming equally powerful forces.

EnerSys Tijuana Battery Plant Closure Shifts Production to US TPPL Facility

EnerSys

EnerSys Tijuana battery plant operations will close as the US-based stored energy systems supplier shifts production to its thin plate pure lead facility in Springfield, Missouri. The move reflects a broader strategy to increase US manufacturing and reduce exposure to tariff risk.

The company said the transition will support greater use of advanced US manufacturing tax benefits. It also positions EnerSys closer to domestic customers at a time when supply chain security and local production have become more important in battery markets.

EnerSys Tijuana battery plant closure also marks a technology shift. The company is moving away from conventional lead-acid battery production in Mexico toward TPPL technology, which it says offers higher power density and stronger discharge performance.

TPPL Technology Strengthens EnerSys’ Domestic Manufacturing Position

TPPL batteries are an advanced form of lead-based energy storage. They are designed to deliver higher power output, faster recharge capability, and improved performance compared with traditional flooded lead-acid systems.

For EnerSys, the Springfield facility gives the company a platform to scale higher-value battery production in the US. This can support applications where reliability, power density, and performance under demanding conditions matter.

The move also fits a wider industrial trend. Battery manufacturers are increasingly reshoring or regionalising production to qualify for incentives, lower tariff exposure, and improve supply certainty.

Tariff Risk and Tax Benefits Reshape Battery Supply Chains

EnerSys Tijuana battery plant closure shows how policy incentives are influencing manufacturing footprints. The company is seeking to maximize advanced US manufacturing tax benefits while reducing uncertainty linked to potential tariffs.

This matters for the broader lead battery supply chain. Domestic TPPL production could increase demand for refined lead, lead alloys, separators, battery components, and recycling-linked feedstock inside the US.

The decision also highlights that energy storage strategy is not only about lithium-ion batteries. Lead-based technologies remain important in backup power, industrial systems, telecom, defense, transportation, and critical infrastructure applications.

The Metalnomist Commentary

EnerSys’ move shows that battery supply chain reshoring is spreading beyond lithium-ion. Policy incentives, tariff risk, and performance upgrades are now reshaping even mature lead-based battery manufacturing.

Global Solid-State Electrolyte Shipments Surge as Semi-Solid Batteries Scale

Solid state electrolyte

Global solid-state electrolyte shipments are rising rapidly as semi-solid batteries move toward vehicle adoption and full solid-state battery commercialisation advances. Chinese research institute EV Tank said shipments reached 4,100t in 2025, more than doubling from a year earlier.

The increase marks an important early-stage signal for the battery materials industry. Electrolytes are one of the core materials that determine the energy density, safety and commercial viability of solid-state batteries.

Global solid-state electrolyte shipments are still small compared with conventional lithium-ion battery materials. However, the growth rate shows that downstream producers are beginning to prepare for larger semi-solid and solid-state battery output.

EV Tank expects global solid-state electrolyte shipments to reach 229,000t by 2030. That would imply a compound annual growth rate of more than 120% from 2025 to 2030, making electrolytes one of the fastest-growing segments in advanced battery materials.

The forecast reflects both technological progress and industrial positioning. Battery producers, automakers and materials companies are now investing ahead of expected demand from electric vehicles, energy storage systems and high-end electronics.

Semi-Solid Batteries Create the First Commercial Demand Base

Semi-solid batteries are likely to provide the first meaningful demand base for solid-state battery electrolytes. EV Tank expects these batteries to begin vehicle adoption from 2026, ahead of full solid-state battery mass production.

This timing matters because semi-solid batteries can act as a bridge technology. They offer improved safety and performance compared with conventional liquid-electrolyte batteries, while avoiding some of the most difficult technical barriers facing all-solid-state cells.

Semi-solid battery growth is already supporting electrolyte shipments. These products still use electrolyte systems that may differ from fully solid-state designs, but they create early commercial demand for sulphide, oxide, polymer, halide and composite electrolyte materials.

Full solid-state batteries are expected to enter small-scale mass production from 2027. That stage will likely remain limited at first because large-scale production still faces technical, cost and qualification challenges.

The market therefore looks likely to develop in phases. Semi-solid batteries will drive early electrolyte consumption, while full solid-state batteries will gradually expand once production processes, interfaces and reliability improve.

Electrolytes are central to this transition. They influence ion conductivity, safety, cycle life, energy density and compatibility with electrodes. Any weakness in electrolyte performance can limit the entire battery system.

This is why electrolyte development is becoming a strategic battleground. Battery makers cannot scale solid-state technology only by changing cell design. They need stable, high-quality electrolyte materials that can be produced consistently at industrial scale.

Capacity expansion is accelerating in response. EV Tank expects producers with annual electrolyte capacity at the thousand-tonne level to emerge within the next one to two years.

That would mark a shift from laboratory and pilot-scale material production toward early industrial supply. It would also create a more competitive market among electrolyte producers seeking qualification with battery manufacturers.

For battery materials suppliers, this creates a new growth category. Electrolytes may become a higher-value segment within the battery chain, especially if producers can meet strict requirements for purity, particle control, stability and conductivity.

For automakers, the key issue is reliability. Vehicle adoption requires materials that can perform under harsh cycling, temperature and safety conditions. This means electrolyte suppliers must pass long qualification cycles before volume demand can fully develop.

Technology Routes and Cost Cuts Shape the Scale-Up

Solid-state battery electrolyte technology remains diversified, especially in semi-solid batteries. Sulphide, oxide, polymer and halide routes are developing in parallel, while both single-electrolyte and composite-electrolyte solutions are being adopted.

This diversity shows that the industry has not yet settled on a single dominant material route. Different technologies offer different advantages in conductivity, stability, manufacturability, cost and safety.

Sulphide electrolytes currently dominate the roadmap for full solid-state batteries. They offer high ionic conductivity and are widely viewed as one of the most promising routes for high-performance battery cells.

However, sulphide systems also face challenges. They require careful handling, moisture control and interface engineering. These factors can raise production complexity and slow commercial scale-up.

Oxide electrolytes offer strong chemical and thermal stability, but they can face processing and interface resistance challenges. Polymer electrolytes offer manufacturing flexibility, but often struggle with conductivity at room temperature. Halide electrolytes are gaining interest because of their electrochemical stability and potential compatibility with high-voltage cathodes.

Composite electrolyte solutions may become increasingly important. By combining material systems, producers can try to balance conductivity, flexibility, stability and manufacturability.

Cost reduction is also becoming a major commercial driver. EV Tank said improvements in material quality and production processes lowered costs across several technology routes in 2025.

Sulphide electrolyte costs fell by more than 35% during the year. This is significant because cost remains one of the biggest obstacles to wider solid-state battery adoption.

Lower electrolyte costs improve the competitiveness of solid-state batteries against conventional lithium-ion technologies. They also make it easier for battery makers to test commercial deployment in premium vehicles, high-performance energy storage and other demanding applications.

Still, cost reduction alone will not guarantee rapid commercialisation. The industry must also solve interface stability, dendrite control, manufacturing yield, pressure management and long-term cycle reliability.

This explains why some major automakers remain cautious. BYD chief scientist Lian Yubo has said solid-state batteries still face core technical bottlenecks and that liquid and solid-state batteries should develop as complementary technologies.

Great Wall Motor also does not expect large-scale commercialisation of all-solid-state batteries in the near term. This caution suggests that the market may grow strongly, but unevenly.

The commercial pathway is therefore not a simple replacement of liquid batteries. Conventional lithium-ion batteries, semi-solid batteries and full solid-state batteries are likely to coexist for years, each serving different cost and performance segments.

This has important implications for materials demand. Solid-state growth could increase demand for lithium metal, high-nickel cathodes, sulphur-based materials, oxides, halides and specialty chemical precursors. But it may not immediately reduce demand for conventional electrolytes, separators or liquid battery components.

The forecast of 229,000t of global solid-state electrolyte shipments by 2030 points to a large materials opportunity. But the final market size will depend on how quickly automakers adopt semi-solid batteries and how successfully full solid-state batteries move from demonstration to reliable mass production.

For supply chains, qualification will be decisive. Battery makers will not buy electrolyte materials only because capacity exists. They will need stable quality, competitive pricing, proven performance and reliable long-term supply.

For policymakers, solid-state batteries are increasingly tied to advanced manufacturing and energy security. Countries that control electrolyte technology and battery production could gain strategic advantage in next-generation electric vehicles and storage systems.

For the metals market, the key point is that battery innovation changes materials demand before full commercial adoption arrives. Producers begin scaling supply years before the technology reaches mass-market vehicles, creating early demand signals and investment cycles.

Global solid-state electrolyte shipments therefore offer a useful indicator of where advanced battery manufacturing is moving. The numbers remain small, but the growth curve is steep enough to attract capital, competition and supply-chain restructuring.

The Metalnomist Commentary

Solid-state electrolyte growth shows that next-generation battery competition is moving upstream into materials engineering. The market will expand quickly, but full solid-state batteries still need technical proof before they can reshape EV and energy storage supply chains at scale.
