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.

CATL Rio Tinto Partnership Targets Mining Electrification and Battery Circularity

CATL

CATL Rio Tinto partnership plans could accelerate electrification across Rio Tinto’s global mining operations as the metals sector looks for practical ways to cut emissions. The two companies have signed a non-binding agreement to explore cooperation in battery technologies, system integration, recycling, and new energy solutions.

The CATL Rio Tinto partnership connects one of the world’s largest battery producers with a major global supplier of iron ore, copper, aluminium, and lithium. This creates a direct link between upstream resource extraction and the battery systems needed to decarbonise mining fleets, rail, and industrial energy use.

Rio Tinto wants to develop a zero-carbon mining model with global demonstration value. CATL will support that goal through its battery technology, energy system expertise, and experience in large-scale electrification.

Battery Systems Move Deeper Into Mining Operations

Mining electrification is becoming a strategic priority because diesel-powered equipment remains a major source of operating emissions. Battery systems can support electric haul trucks, heavy equipment, rail locomotives, site power systems, and charging infrastructure.

The collaboration could help Rio Tinto improve operating efficiency while reducing carbon intensity. Electrified mining systems may also lower fuel exposure, improve maintenance economics, and support customers that increasingly demand lower-carbon raw materials.

The agreement also reflects a broader shift in mining procurement. Large miners are no longer only buying equipment; they are building partnerships around batteries, energy management, recycling, and circular material flows. This gives battery companies a larger role in mining’s industrial transition.

Critical Minerals Circularity Becomes a Strategic Link

The CATL Rio Tinto partnership will also explore business models for battery materials recycling and critical minerals circularity. This is important because mining electrification will create new demand for lithium, copper, nickel, graphite, rare earths, and other battery-linked materials.

Circularity can help reduce waste and strengthen supply security. If battery materials can be recovered and reused across mining operations, companies can reduce dependence on fresh raw material inputs and build more resilient supply chains.

CATL and BYD are increasingly targeting partnerships with major miners and energy companies. CATL and BYD have already signed agreements with BHP to develop battery solutions for mining equipment and railway locomotives, while BYD has also agreed to work with Aramco on electric and fuel cell vehicle technologies.

The Metalnomist Commentary

Mining electrification is becoming a new battleground for battery companies, miners, and equipment suppliers. The strategic winners will be those that can connect mineral supply, battery deployment, recycling, and low-carbon operations into one industrial ecosystem.

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.

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.

Battery Energy Storage Systems Accelerate Data Center Deployment

Battery Energy Storage Systems

Battery energy storage systems are becoming a practical tool for accelerating data center deployment as hyperscalers search for faster access to power. Industry executives said storage, combined with solar and wind, can help large technology companies bring major facilities online more quickly.

The discussion reflects a growing reality in the power market. Data center demand is rising alongside broader electrification, placing pressure on grids that were not designed for such rapid large-load growth.

Battery energy storage systems help address this problem by providing flexibility where grid connections, peak demand, or local capacity constraints delay projects. For hyperscalers, speed to power is now as important as land, chips, cooling, and fiber connectivity.

Storage Becomes a Bridge Between Hyperscalers and Grid Constraints

Battery energy storage systems can help data centers manage peak demand, reduce grid stress, and support faster deployment when full baseload supply is not immediately available. This makes storage a bridge between large electricity users and constrained power systems.

Invenergy said a mix of solar, wind, and storage can give hyperscalers strong speed-to-power advantages while remaining affordable. That combination is increasingly attractive because data centers need large volumes of electricity but also face public scrutiny over power prices.

The affordability issue is becoming more sensitive. US electricity prices rose by 6.3% in January, and rising demand from data centers is one of the factors adding pressure. If households feel they are paying more while large-load users secure cheaper power, the political risk around data center growth will increase.

Flexible Power Models Could Reshape Battery Demand

Technology companies are responding with a wider power strategy. Instead of relying only on large central power plants, they are looking at solar, wind, on-site batteries, demand response, and distributed storage.

Google said that in locations where peaking capacity is the main issue, faster solutions may include ramping down for short periods, switching to on-site batteries, or paying other customers to install batteries in their homes. This approach turns batteries into grid flexibility assets, not only backup systems.

For the materials supply chain, this matters because data center growth could become a stronger demand driver for batteries, lithium, graphite, iron phosphate materials, copper, aluminium, transformers, power electronics, and grid equipment. As AI infrastructure scales, battery storage will increasingly sit at the intersection of digital infrastructure and energy security.

The Metalnomist Commentary

Battery energy storage systems are moving from optional backup equipment to strategic infrastructure for hyperscaler growth. The next bottleneck for AI data centers may not be computing hardware alone, but the ability to secure flexible, affordable, and politically acceptable power.

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 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.

Battery Metals Demand Faces Slower Path as Hybrid Vehicle Growth Extends

Battery Metals

Battery metals demand could face a slower growth path as carmakers and suppliers expect hybrids and range extenders to remain important for longer than earlier electric-only transition models assumed. Speakers at the FT Future of the Car summit said vehicle decarbonisation should be measured by emissions reduction, not only battery electric vehicle share.

Battery metals demand remains structurally supported by electrification. However, a longer hybrid phase could reduce near-term demand intensity for lithium, nickel, cobalt and manganese because hybrid vehicles use smaller battery packs than full battery electric vehicles.

Battery metals demand assumptions are therefore becoming more complex. Automotive electrification is still progressing, but the industry is moving toward a mixed powertrain future rather than a simple shift from combustion engines to full BEVs.

Horse Powertrain chief executive Matias Giannini said half of passenger vehicles could still be produced with some form of combustion or hybrid powertrain by 2040. That outlook would keep investment flowing into efficient hybrid systems alongside EV platforms.

Hybrid Growth Changes the Battery Raw Materials Curve

Hybrid vehicle growth could temper the pace of battery raw material demand without reversing electrification. Hybrids and range extenders still require electric motors, inverters, wiring and batteries, but their battery packs are much smaller than those used in BEVs.

This matters most for nickel. High-nickel NCM and NCA batteries are closely tied to longer-range BEVs, where larger packs are needed to deliver performance and driving range.

A slower BEV ramp-up could delay some of the nickel sulphate demand growth that has supported investment cases for new battery-grade nickel projects. It could also affect cobalt and manganese demand in cathode chemistries exposed to full EV penetration rates.

Lithium remains supported across almost every electrification pathway. Still, a longer hybrid transition could slow the rate at which large-format BEV batteries absorb lithium units.

The shift does not mean automotive metals demand will weaken across the board. Hybrids use more copper than conventional combustion vehicles because they require electric motors, power electronics and more complex wiring systems.

Continued hybrid and combustion production also supports aluminium castings, stainless steel, exhaust components and engine-related materials. Meanwhile, BEV growth still supports aluminium lightweighting, copper wiring, charging infrastructure and battery materials.

The result is a less linear automotive metals outlook. Battery metals may grow more slowly than aggressive BEV scenarios suggest, while broader automotive metals consumption remains supported by platform complexity and mixed powertrain production.

Policy Flexibility Could Reshape European Metal Demand

European suppliers are pushing for more flexibility in the EU regulatory framework. Current policy remains heavily weighted toward full electrification through tailpipe emissions targets.

The EU targets a 100% reduction in tailpipe emissions from new cars and vans from 2035. That effectively ends new combustion engine sales unless future exemptions are created.

Industry participants increasingly want a more technology-neutral route. They argue that hybrids, range extenders, renewable fuels and lower-carbon manufacturing should contribute to emissions reduction alongside BEVs.

This policy debate matters for metals. Battery material demand depends heavily on BEV penetration, average pack size and chemistry choice.

If Europe allows a longer role for hybrids and range extenders, lithium-ion battery capacity demand per vehicle could grow more slowly. That would affect demand forecasts for lithium, nickel, cobalt and manganese.

Chinese EV and hybrid technology is also improving quickly. This puts pressure on European and US automakers to share development costs across BEV, hybrid and range-extender platforms.

For suppliers, the strategic issue is flexibility. Companies tied only to high-growth BEV battery assumptions may face demand timing risk, while suppliers serving copper, aluminium, stainless steel, electronics and hybrid systems may benefit from a broader platform mix.

The automotive transition is still real, but the material demand path is becoming more diversified. Metals markets must now track powertrain mix, not only EV sales headlines.

The Metalnomist Commentary

Hybrid growth does not weaken the energy transition, but it changes the metals timing. Battery metals demand will still rise, yet copper, aluminium and hybrid-related materials may capture more value if automakers choose a longer mixed-powertrain route.

Panasonic Reports Increased Profits in Q3 2024, Driven by Storage Battery Demand and AI Growth

Panasonic

Japanese Battery Maker Sees Strong Performance in Automotive and Storage Battery Segments Amid Growing AI Demand

Panasonic, a leading Japanese battery producer, reported a notable increase in profits for the third fiscal quarter ending December 31, 2024. The company posted a profit of ¥132.2 billion ($862 million), marking a 15% rise compared to the same period last year. This growth was primarily driven by stronger sales of its storage battery systems, especially to data centers, fueled by the rising adoption of generative artificial intelligence (AI) technologies.

Growth in Storage Battery Sales and AI Demand

Panasonic’s strong performance in the storage battery segment reflects the growing demand for energy storage solutions, particularly for data centers. The company did not disclose specific sales volumes but highlighted that AI's rapid growth has significantly contributed to increased sales of its storage battery systems. This aligns with global trends, where AI's demands for high-performance computing infrastructure are pushing data centers to invest in more efficient energy solutions.

In response to the strong growth in the storage battery sector, Panasonic has revised its full-year outlook. The company raised its profit forecast for its battery segment by ¥15 billion, now projecting ¥124 billion for the fiscal year ending March 31, 2025. Panasonic expects the demand for storage batteries driven by AI technologies to continue, further enhancing its financial outlook.

Automotive Battery Sales and US Production Facilities

Panasonic's automotive battery business also saw a significant boost, with profits increasing by ¥2.6 billion compared to the previous year. This growth was attributed to higher battery shipments from its Nevada plant in the United States, where improved productivity has helped meet the rising demand for batteries in electric vehicles (EVs). The company’s investments in new battery production facilities in Kansas and Japan’s Wakayama prefecture helped offset initial investment costs.

Despite the potential impact of recent US tariff hikes on imports from Canada and Mexico, Panasonic anticipates minimal disruption to its operations. The company emphasized that its major battery production bases, including those in Kansas, are located within the US, which should shield it from significant negative effects from these tariffs.

Confidence in the Global EV Market

Looking ahead, Panasonic remains confident in the global EV market's growth, despite potential slowdowns in certain regions. The company believes that the overall expansion of the electric vehicle market will continue, regardless of fluctuations in growth rates. Panasonic's strategy of investing in battery production only in response to confirmed client demand ensures that the company will likely achieve a solid return on its investments, positioning it well for future growth.

In conclusion, Panasonic’s impressive performance in Q3 2024 underscores its strong position in the battery industry. With a robust outlook for storage batteries driven by AI and sustained growth in its automotive battery sector, Panasonic is poised for continued success.

Rio Tinto battery swap trial advances low-emission mining

Rio Tinto Battery swap

Rio Tinto battery swap trial at Oyu Tolgoi signals a step-change in low-emission surface mining. The Rio Tinto battery swap trial, launched with China’s SPIC Qiyuan, will test electric haul trucks in demanding operating conditions. As a result, the Rio Tinto battery swap trial could become a blueprint for fleet decarbonisation across global open-pit operations.

Battery swap technology at Oyu Tolgoi

The Rio Tinto battery swap trial introduces electric haul trucks that can change batteries in under seven minutes. Battery swapping avoids long fast-charging pauses and keeps haul trucks in near-continuous operation. Over the past year, Rio Tinto and SPIC Qiyuan deployed eight 91t Tonly trucks, 13 800kWh batteries and a swap station. This infrastructure also includes a static charger and supporting grid connections at the Mongolian copper mine.

The trial will initially support tailings dam construction and topsoil movements at Oyu Tolgoi. These tasks provide repeatable cycles that are ideal for testing battery performance and swap logistics. Meanwhile, the project will generate real-world data on duty cycles, energy use and maintenance needs. That data will be critical for scaling battery swap systems into harsher and deeper mining environments.

Scaling battery swap across Rio Tinto’s global truck fleet

Rio Tinto sees its 700-truck global fleet as a major opportunity for wider battery swap deployment. If successful, the Rio Tinto battery swap trial could enable progressive replacement of diesel trucks in high-volume pits. Battery swap systems also align with grid-connected power strategies at large copper and iron ore operations. However, scaling will depend on local power availability, grid stability and renewable energy penetration.

Partnership with SPIC Qiyuan gives Rio Tinto access to China’s fast-moving battery and power electronics ecosystem. Chinese suppliers have already commercialised battery swap technology in logistics and urban transport fleets. Therefore, this mining-focused collaboration may accelerate standardisation of battery packs, swap stations and digital control platforms. That standardisation would reduce costs and support adoption by other global mining companies.

The Metalnomist Commentary

This trial confirms that decarbonising mining fleets is shifting from concept studies to large-scale pilots. Battery swap technology addresses one of mining’s hardest problems: keeping heavy haulage electrified without sacrificing productivity. If Oyu Tolgoi proves the model, expect copycat projects in copper, iron ore and coal, especially where grid power and renewables are available.

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.

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.

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.

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.

Japan EU battery recycling alliance aims to cut China dependence

Japan, EU battery alliance

Japan EU battery recycling alliance marks a strategic push to reduce reliance on China in battery materials. The new Japan EU battery recycling alliance brings together key industry groups to strengthen recycling, black mass handling and data sharing. As a result, the Japan EU battery recycling alliance targets a more resilient and transparent battery supply chain across both regions.

Japan EU battery recycling alliance links tech strength and market scale

The Japan EU battery recycling alliance is built around three core industry associations. Japan’s Battery Association for Supply Chain, the European Battery Alliance and Brussels based Recharge have signed an initial agreement. Together, they will cooperate on improving recycling processes, materials flows and supply chain governance.

The agreement covers information exchange on issues such as data sharing and regulatory interpretation. It also includes joint studies on black mass classification, a key bottleneck for cross border recycling flows. Black mass refers to shredded cathode material containing nickel, cobalt and lithium from spent batteries. Therefore, clear definitions and standards for black mass are critical for trade, permitting and ESG compliance.

Japanese officials highlight the importance of combining Japan’s technology strength with Europe’s market size. Japan offers advanced recycling technologies and process know how developed over decades of battery manufacturing. Meanwhile, Europe provides a rapidly growing battery market driven by EV mandates and energy storage deployment. This mix gives the Japan EU battery recycling alliance strong industrial foundations.

Reducing strategic exposure to China dominated battery materials

The Japan EU battery recycling alliance clearly responds to geopolitical supply concerns. Officials from Japan’s trade and industry ministry note that the current battery supply chain depends heavily on one country. Although unnamed, the reference clearly points to China’s dominance in processed lithium, nickel, cobalt and anode materials.

By deepening cooperation, Tokyo and Brussels aim to reduce vulnerability to export controls or political friction. Recycling and black mass trade can partially offset primary supply risks from Chinese refineries and processors. In addition, improved data sharing should help track origin, quality and ESG performance of recovered materials. As a result, the Japan EU battery recycling alliance supports compliance with emerging battery passport and due diligence rules.

The initiative also fits within the broader Japan EU competitiveness alliance launched in July. That framework seeks closer coordination on semiconductors, clean energy, critical minerals and industrial standards. Battery recycling now becomes a visible test case for how quickly the partnership can move from statements to practical projects.

The Metalnomist Commentary

This partnership underlines how recycling is moving from a niche activity to a core pillar of battery security strategy. If the Japan EU battery recycling alliance can harmonise black mass standards and data systems, it will lower barriers for serious cross regional recycling investment. Market participants should watch for pilot projects, joint ventures and regulatory tweaks that follow this initial, largely framework level agreement.

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.

Tesla

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.

Falling Battery Costs Drive Longer Duration Energy Storage Expansion

CERAWeek

Shift to LFP chemistry and falling raw material prices boost two-hour-plus BESS projects, but SoC accuracy remains a hurdle.

Lower Battery Costs Accelerate BESS Deployment

Lower battery prices are transforming the energy storage market by enabling more battery energy storage systems (BESS) with longer durations, according to experts at the CERAWeek by S&P Global conference in Houston. Charlotte Johnson, general manager of InfraFlex (a Kraken unit), stated, "Lower prices have accelerated the deployment of BESS of two hours and more, rather than the one-hour systems."

Battery cells represent about 50% of total project costs, while the remainder goes to labor, operations, and maintenance. As battery cell costs fall, project developers are increasingly building longer-duration BESS to meet grid flexibility and renewable integration needs.

LFP Batteries Drive Cost Cuts but Add Challenges

The price drop stems largely from falling battery raw material costs and a rapid shift to lithium iron phosphate (LFP) battery chemistry. LFP cells are cheaper and more stable than nickel-based alternatives, making them ideal for utility-scale BESS projects.

However, panelists warned of a drawback: LFP systems have less predictable state of charge (SoC) behavior. Inaccurate SoC readings complicate real-time optimization and revenue maximization for grid operators and energy traders.

Outlook: Market Growth Continues Amid Technical Hurdles

While SoC monitoring remains a challenge, the economic advantages of LFP and longer-duration storage outweigh the downsides for now. Developers and technology providers are focusing on improving SoC management tools and software to unlock greater value from low-cost, longer-duration systems.
