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.

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.

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.

Zhongke Anode Material Sales Surge as Energy Storage Demand Accelerates

Zhongke

Zhongke anode material sales rose sharply in 2025 as China’s lithium-ion battery sector expanded across new energy vehicles and power storage. Hunan Zhongke Electric sold 363,253t of anode materials during the year, up 62% from 2024.

Zhongke anode material sales were supported by strong downstream demand and higher operating rates. The company’s output increased by 66% to 378,469t, reflecting a rapid scale-up in response to battery market growth.

Zhongke anode material sales also lifted revenue. Revenue from anode materials rose by 60% to 7.99bn yuan, broadly in line with the increase in shipment volumes.

The result shows how anode materials remain one of the key beneficiaries of battery expansion. Demand is no longer driven only by electric vehicles. Grid storage, industrial storage and AI-related power demand are becoming increasingly important.

Capacity Utilisation Tightens as China Battery Demand Expands

Zhongke’s anode material capacity reached 348,683 t/yr in 2025, up 46% from a year earlier. The increase followed equipment and technology upgrades across its production base.

Capacity utilisation rose to 108.6% from 95.7% in 2024. This shows that Zhongke was operating above nameplate capacity as demand outpaced available production capability.

The company is now expanding further. A third-phase project at its Zhaotong site in Yunnan province is under construction and will add 100,000 t/yr of anode material capacity by the end of 2026.

Zhaotong has become a key growth platform. The first phase, with 15,000 t/yr of capacity, started production in April 2020. The second phase, with 100,000 t/yr of capacity, began operations in March 2024.

Zhongke is also planning a 300,000 t/yr anode material complex in Luzhou, Sichuan province. This would further strengthen its position in China’s graphite anode supply chain.

The expansion reflects a broader industry trend. Anode producers are adding capacity to serve battery makers that need reliable supply, stable quality and lower-cost materials for high-volume cell production.

Overseas Expansion Targets Storage and Non-China Customers

Zhongke is also building a 100,000 t/yr anode material plant in Tangier, Morocco. The project targets customers outside China and reflects the growing need for regionalised battery material supply chains.

Morocco offers strategic value because it is close to European markets and has become more attractive for battery-related investment. For Chinese anode producers, overseas capacity can help serve customers facing localisation, trade and supply-chain security requirements.

Energy storage is becoming a major long-term demand driver. Global energy storage battery shipments reached 651.5GWh in 2025, up 76.2% from a year earlier. Chinese companies accounted for 614.7GWh, or 94.4% of global shipments.

EV Tank expects global energy storage battery shipments to exceed 2TWh by 2030. If this forecast materialises, anode material demand will continue rising across China and overseas markets.

Policy is also supporting growth. China is moving new energy storage from mandatory allocation toward a more market-oriented system, including capacity pricing support for independent grid-side storage.

AI data centres are adding another demand layer. Rapid growth in electricity consumption from AI infrastructure is increasing the need for power storage, grid stability and backup capacity.

Europe is also expanding storage under energy security strategies. EU member states installed 27.1GWh of new battery energy storage systems in 2025, up 45% from the previous year.

For Zhongke, this demand mix supports a larger and more international anode strategy. The company is positioning itself to serve China’s dominant battery ecosystem while preparing for overseas demand linked to storage, EVs and grid resilience.

The Metalnomist Commentary

Zhongke’s growth shows that anode materials are moving from an EV-driven market into a broader energy infrastructure market. The next competitive phase will depend on overseas localisation, graphite supply security and the ability to serve storage demand outside China.

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.

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.

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.

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.

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.

China Battery Overcapacity Crackdown Targets Price Wars and Overseas Expansion

China Battery

China battery overcapacity concerns deepened after government authorities held another meeting with leading power and energy storage battery producers on 9 April. The meeting signalled stronger regulatory pressure on disorderly competition, low-price strategies and excessive capacity expansion in the lithium battery sector.

The meeting brought together 16 major battery producers and several industry associations. It was the second such regulatory session since January, showing that Beijing sees battery overcapacity as a structural industrial risk rather than a short-term market adjustment.

China battery overcapacity has grown as domestic and overseas capacity plans have moved far ahead of actual demand. Regulators are now seeking capacity early-warning mechanisms, stronger market-order controls and tighter oversight of aggressive price competition.

Regulators Target Involution-Style Competition

Chinese authorities said the meeting aimed to implement senior government directives against “involution-style” competition. This term refers to excessive internal rivalry that destroys margins, weakens investment discipline and creates unsustainable price wars.

Regulators also discussed a negative list of irrational competitive practices in the power and energy storage battery industry. This would give authorities a clearer tool to identify and restrict behaviour that destabilises the market.

The new focus on the “externalisation of involution” is especially important. It shows that Beijing is now concerned not only about domestic overcapacity, but also about excessive overseas expansion by Chinese battery producers.

Chinese battery companies have accelerated global plant construction to serve overseas demand and reduce exposure to geopolitical restrictions. But if too much capacity is exported abroad, price pressure could spread into global power battery and energy storage markets.

Capacity Mismatch Creates Pressure Across Battery Materials

China’s power and energy storage battery output reached 1,755.6GWh in 2025, up 60.1% from a year earlier. Sales rose by 63.6% to 1,700.5GWh, confirming strong demand growth but also exposing the scale of capacity pressure.

Planned national capacity has climbed close to 5,000GWh. That implies utilisation rates below 40%, which helps explain why regulators are concerned about price wars and weak production discipline.

The issue also matters for battery materials. Overcapacity can pressure cathode active materials, precursors, lithium carbonate, graphite, copper foil, separators and electrolytes if producers chase volumes rather than margins.

Chinese battery firms are also becoming more important abroad. CATL, BYD, Gotion High-Tech, Farasis Energy, SVOLT Energy and CALB recorded 218GWh of overseas power battery installations in 2025, accounting for 47.2% of the global market.

The Metalnomist Commentary

China’s battery crackdown shows that scale alone is no longer enough. The next phase of battery competition will reward disciplined capacity, stronger technology, regional supply-chain positioning and healthier margins over pure volume growth.

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.

Japex storage battery station supports Hokkaido renewable energy growth

Japex

Japex storage battery station development in Hokkaido marks a strategic shift in Japan’s upstream energy companies toward grid flexibility. The new Japex storage battery station in Tomakomai will support a stable supply of renewable energy as variable output rises. As a result, the project strengthens Japan’s broader push to integrate large-scale renewables without sacrificing reliability.

Japex will build the Tomakomai storage battery station as one of Japan’s largest power-storage facilities, with 20MW capacity. The company targets commercial operations in autumn 2027, aligning the Japex storage battery station with accelerating wind and solar additions in Hokkaido. Meanwhile, the firm highlights that storage batteries will play a growing role in balancing renewable energy output and maintaining grid stability.

Hokkaido emerges as a storage and renewables cluster

Hokkaido offers Japex strong fundamentals for expanding its battery storage business. The region already hosts significant renewable energy capacity and has made visible progress in adopting storage solutions. Therefore, locating the Japex storage battery station in Tomakomai leverages both existing infrastructure and future solar and wind growth.

Japex has already commissioned a smaller 2MW storage battery station in Chiba prefecture, gaining early operational experience. In Tomakomai, the company also runs two solar power plants and plans another for 2028, further deepening its presence in low-carbon assets. However, Japex emphasizes that the Tomakomai storage battery station will operate as a grid-level resource rather than being tied to a single power plant. This design allows the asset to respond dynamically to system needs across the local network.

The Metalnomist Commentary

Japex’s move into large-scale storage signals how traditional upstream players are repositioning for a decarbonised power system. By building a major storage hub in Hokkaido, the company is not just following renewable growth but actively enabling it. For metals and battery supply chains, sustained roll-out of 20MW-class projects across Japan will reinforce long-term demand for advanced battery materials and grid technologies.

Global Energy Storage Battery Shipments Surge in 2024

CATL

Global shipments of energy storage batteries experienced a significant increase in 2024, driven by rising demand and reduced manufacturing costs. According to Chinese research institute EV Tank, global shipments totaled 369.8GWh, reflecting a 65% increase from the previous year.

China Leads the Global Energy Storage Market

Chinese manufacturers played a dominant role in this surge, accounting for 93.5% of global shipments with a total of 345.8GWh. The growth can be attributed to China’s favorable incentive policies and the decreasing cost of battery cell production, which has bolstered shipments of energy storage batteries, particularly to the power industry. Energy storage systems in power grids remain the largest downstream market, with an 83.3% share of global demand in 2024.

Strong Growth Expected Through 2030

EV Tank forecasts that global energy storage battery shipments will continue to rise, reaching 1,550GWh by 2030. This growth will be fueled by increased demand from both traditional markets in Europe and the U.S., as well as emerging regional markets. The steady demand from these areas is expected to play a key role in driving the industry forward in the coming years.

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.

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.

This project exemplifies how energy storage drives critical mineral demand while enabling renewable energy integration at scale.

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.

These results further establish BYD as a global ESS leader, particularly as Chinese companies accounted for 93.5% of global energy storage shipments last year. In total, global energy storage battery shipments hit 369.8GWh in 2024—a 65% year-on-year increase.

Energy storage drives Saudi diversification efforts

The partnership between BYD and Saudi Electric Power aligns with the kingdom’s strategic push toward energy diversification and grid modernization. As Saudi Arabia ramps up utility-scale solar and wind projects, the need for large-scale battery storage grows rapidly.

BYD’s advanced LFP technology offers long cycle life, thermal stability, and safety—making it ideal for the desert climate and high-demand grid applications in the region. This deal positions BYD as a critical technology supplier in Saudi Arabia’s clean energy roadmap.

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.
