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.

Meanwhile, the battery cell project in West Java accounts for $1.2bn of the total budget.

Indonesia’s mineral advantage meets China’s battery expertise

Indonesia holds abundant nickel, cobalt, and manganese, essential for EV batteries, but lacks lithium and advanced technology. Therefore, Antam partnered with CATL to secure the expertise and technology required. By 2026, smelting and hydrometallurgy plants, alongside a nickel-cobalt-manganese precursor facility, are expected to strengthen Indonesia’s midstream value chain. This partnership underscores a growing alignment between Indonesia’s resource base and China’s global battery leadership.

Energy independence and EV market expansion

The Indonesia-China EV battery joint venture could supply batteries for 300,000 EVs annually, potentially reducing fuel imports by 300,000 kilolitres per year. President Prabowo stated that Indonesia could reach full energy self-sufficiency within five to seven years, provided battery production grows to 100GWh annually. As a result, Indonesia is positioning itself not just as a raw material supplier but as an integrated EV hub.

The Metalnomist Commentary

Indonesia’s partnership with CATL cements its role in the global EV battery supply chain. However, success depends on infrastructure, environmental safeguards, and balancing resource nationalism with foreign investment. If executed effectively, Indonesia could become a strategic alternative to China-dominated supply routes.

Global Battery Demand Nears 1TWh in 2024 as LFP Market Share Surges

Battery

EV Growth and China Lead Surge in Battery Demand

Global battery demand reached nearly 1TWh in 2024, largely driven by rising electric vehicle (EV) adoption, according to the IEA's latest EV Outlook 2025. The Focus Keyphrase "global battery demand" continues to dominate energy transition narratives as EV sales accelerate across major economies.

EV battery demand alone exceeded 950GWh, accounting for more than 85% of total battery consumption. China led with 59% of EV battery demand, followed by the U.S. and EU, each holding a 13% share. The IEA projects battery demand will more than triple to over 3TWh by 2030 under current national policies. While supply of critical minerals is currently in surplus, the IEA warns that depressed prices could deter future investment, risking lithium and nickel shortages by decade’s end.

Battery Manufacturing Grows Faster Than Demand

Global battery manufacturing capacity grew by nearly 30% to 3.3TWh in 2024, tripling actual demand. If all announced projects proceed, capacity could reach 6.5TWh by 2030, outpacing the IEA’s projected demand.

South Korea led overseas battery capacity expansion with over 400GWh deployed in 2024, far ahead of Japan (60GWh) and China (30GWh). If planned projects materialize, South Korea could produce over 1TWh annually by 2030, almost double China’s expected output. As a result, China’s global manufacturing share is projected to fall from 85% in 2024 to two-thirds by 2030, diversifying global supply chains.

LFP Dominates Market as Regional Dynamics Shift

Lithium iron phosphate (LFP) batteries now make up nearly half of the global EV battery market, with Chinese producers holding a de facto monopoly, especially in Europe and the U.S. European OEMs are increasingly opting for LFP chemistries to cut costs, displacing South Korean suppliers.

South Korean battery makers’ EU market share fell to 60% in 2024, down from 80% in 2022, while their U.S. market share rose to 35%, closing in on Japan’s 48%. Major Korean firms — LG Energy Solution, SK On, Samsung SDI — are all preparing for mass LFP production to compete in this fast-growing segment.

Meanwhile, LFP adoption in Southeast Asia, Brazil, and India has surpassed 50% of battery electric car sales, signaling rapid global penetration. However, Japanese battery makers face domestic setbacks, highlighted by Nissan’s cancellation of its Kyushu LFP plant amid restructuring.

The Metalnomist Commentary

The rise in global battery demand underscores a structural transformation in energy, mobility, and manufacturing. While demand growth is robust, the oversupply of battery capacity and volatility in mineral prices highlight the sector’s growing pains. As LFP continues its global ascent, regional competition and vertical integration will shape the future of the battery ecosystem.

Strategic Project Targets Heavy Vehicle Transportation

However, Sinopec and CATL finalized a specific agreement on May 21st for the Qiji Exchange Station project focused on heavy trucks in Fujian province. The project will serve critical road freight transportation along the coastal route between the Yangtze River Delta and Pearl River Delta using CATL's latest battery exchange system technology. This heavy vehicle focus addresses a key market segment where battery exchange offers significant advantages over traditional charging methods.

Therefore, the heavy truck application demonstrates practical implementation of battery exchange technology for commercial vehicles requiring rapid turnaround times. The coastal corridor route represents one of China's most important freight transportation arteries, making successful deployment here a potential template for nationwide expansion. The project showcases how traditional energy companies can integrate new energy technologies into existing transportation infrastructure.

Traditional Energy Companies Embrace New Energy Transition

Furthermore, Sinopec's investment reflects broader trends among conventional energy companies accelerating investments in new energy markets. State-run energy firm PetroChina launched a "supercharger station" in Shanghai's Yili road area in March, demonstrating industry-wide recognition of EV infrastructure opportunities. These companies leverage existing real estate assets and customer relationships to enter growing new energy segments.

As a result, joint ventures between traditional energy companies and EV technology providers create synergistic opportunities for rapid infrastructure deployment. PetroChina, SAIC, Sinopec, and CATL established the Shanghai JieNeng Zhidui New Energy Technology joint venture in September 2022 to lease EV battery packs and develop battery exchange technology. CATL's construction of a 40 GWh annual capacity factory in Dongying, China's largest oil refining city, further strengthens these traditional energy sector connections.

The Metalnomist Commentary

Sinopec's cornerstone investment in CATL's record-breaking IPO exemplifies how China's traditional energy giants are strategically positioning themselves within the electric vehicle ecosystem, leveraging their existing infrastructure assets to capture new revenue streams in battery exchange services. The partnership's focus on heavy vehicle applications addresses a critical market need where battery exchange technology offers compelling advantages over conventional charging, potentially accelerating commercial EV adoption across China's logistics sectors.

LGES Exits Indonesia EV Battery Project Amid Strategic Shift

LGES

LGES exits Indonesia EV project

LGES exits Indonesia EV project, marking a significant shift in its global battery strategy.

South Korea’s LG Energy Solution (LGES) has officially withdrawn from Indonesia’s $8.4 billion Grand Package EV battery initiative.

The project originally included LGES, LG Chem, Posco Future M, Huayou, Antam, and Indonesia Battery Corporation. Plans had outlined a complete value chain: from mining and smelting to precursor, cathode, and battery cell production.

Strategic Refocus on Core Ventures and Energy Storage

LGES exits Indonesia EV project while reaffirming its commitment to the HLI Green Power joint venture with Hyundai Motor. This Indonesian JV plant has a 10 GWh annual battery cell capacity and began mass production in April 2024.

Meanwhile, LGES continues to diversify beyond the EV battery sector. It has secured energy storage system (ESS) battery contracts with Delta Electronics in Taiwan and PGE in Poland.

Indonesia Presence Maintained Through LFP and JV Assets

Despite the LGES exit from the Indonesia EV project, the company retains stakes in key Indonesian operations. Earlier this year, LGES invested in a lithium iron phosphate (LFP) cathode plant with China’s Lopal Tech.

LGES emphasized its intent to continue collaboration with the Indonesian government, particularly via its joint venture HLI Green Power. This signals a strategic recalibration rather than a full-scale withdrawal from the Indonesian battery ecosystem.

The Metalnomist Commentary

LGES’s departure reflects a broader recalibration of battery majors toward diversified revenue streams and scalable ESS markets. The company’s sustained Indonesian footprint suggests long-term positioning, albeit through leaner, more focused partnerships.

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.

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.

Sales mirrored production, with 1.835 million NEVs sold—a strong signal of consumer confidence and supportive policy. CPCA projects 2025 NEV sales will exceed 15.65 million units, up 28% from 2024, sustaining China’s global lead in electric mobility.

The Metalnomist Commentary

The CATL–Sinopec alliance marks a pivotal shift in China's EV ecosystem. Battery-swapping offers a fast, scalable solution to charging delays. By aligning infrastructure with battery tech, China could set a global standard for EV convenience—especially for fleet operators and logistics.

Honda Ontario EV Plan Suspended Amid Slower Market Growth Projections

Honda EV

Honda suspended its ambitious C$15 billion ($10.7 billion) Honda Ontario EV plan to build a comprehensive electric vehicle value chain in Canada. Chief Executive Toshihiro Mibe announced the two-year delay during the company's first-quarter earnings presentation, citing slower-than-expected EV market growth. The Honda Ontario EV plan postponement represents a significant setback for Canada's battery materials supply chain development and critical mineral processing ambitions.

Comprehensive Battery Supply Chain Project Faces Market Reality

The Honda Ontario EV plan encompassed a complete electric vehicle manufacturing ecosystem in Alliston, Ontario, including an EV assembly plant and standalone battery manufacturing facility. Honda partnered with Posco Future M to develop cathode and precursor materials facilities while collaborating with Asahi Kasei on separator plant construction. Meanwhile, this integrated approach aimed to reduce supply chain dependencies while supporting Honda's goal of 100% battery and fuel cell EV sales by 2040.

The comprehensive nature of the Honda Ontario EV plan positioned Canada as a strategic hub for North American electric vehicle production. Honda's investment would have created substantial demand for Canadian critical minerals, particularly lithium, nickel, and cobalt for battery cathode materials. However, slower market adoption rates have forced automakers to reassess their aggressive electrification timelines and associated capital investments.

Critical Mineral Processing Ambitions Face Automotive Headwinds

Canada's strategy to capture value from its abundant critical mineral resources through downstream processing suffers a major blow from the Honda Ontario EV plan suspension. The project represented a key opportunity to establish domestic battery materials manufacturing capabilities using Canadian lithium, nickel, and graphite resources. As a result, the delay undermines government efforts to build integrated critical mineral supply chains within North America.

Posco Future M's planned cathode and precursor facilities would have processed Canadian-sourced critical minerals into high-value battery materials for Honda's EV production. The partnership promised technology transfer and manufacturing expertise to establish Canada's position in global battery supply chains. Therefore, the Honda Ontario EV plan postponement reduces near-term demand prospects for Canadian critical mineral producers seeking domestic processing partnerships.

The two-year delay reflects broader challenges facing automaker electrification strategies as consumer adoption lags initial projections. Honda joins other manufacturers reassessing EV investment timelines amid market uncertainty and profitability concerns. Consequently, critical mineral demand growth may moderate as automakers adjust production capacity plans to match actual market conditions.

The Metalnomist Commentary

Honda's decision to pause its massive Ontario investment reflects the gap between aggressive EV transition rhetoric and market reality, highlighting risks for critical mineral producers banking on rapid battery demand growth. This setback underscores the importance of diversified demand strategies for Canadian critical mineral projects, as automotive electrification timelines prove more volatile than anticipated across the industry.

Hydro Takes Full Ownership of Battery Recycler Hydrovolt

Hydrovolt

This acquisition comes as Northvolt faces financial challenges, having filed for Chapter 11 bankruptcy in November 2024 due to substantial debt. Hydro, which has been solely financing Hydrovolt's operations since mid-2024, now seeks a new partner to secure long-term funding for the subsidiary.

Strategic Significance

Hydro's full ownership of Hydrovolt underscores its commitment to sustainable and circular solutions within the aluminum and battery value chains. This strategic move strengthens Hydro's position in the burgeoning EV battery recycling market, contributing to a more environmentally responsible and resource-efficient industry.

Latam EV Market Set for Massive 2025 Expansion Driven by Chinese Automakers

Latam EV Market

The Latam EV market will experience unprecedented growth in 2025 as electric vehicle sales in Latin America and emerging markets double to 1 million units. According to the International Energy Agency (IEA), Chinese automakers drive this expansion by offering significantly cheaper models than traditional Western brands. The Latam EV market surge represents a critical shift in global automotive demand that will substantially increase battery materials consumption across the region.

Chinese Battery Technology Advantages Fuel Market Penetration

Chinese automakers captured 75% of all EV sales in emerging economies by leveraging superior cost advantages in battery pack manufacturing. China produces cheaper battery packs due to intense competition, enhanced manufacturing efficiency, supply chain integration, and access to skilled workforces. Meanwhile, Chinese battery pack prices fell 30% compared to only 10-15% decreases in Europe and the United States.

BYD and GWM electric vehicles now compete directly with conventional petrol cars in key Latam EV market segments. In Brazil, BYD's largest market outside China, the price gap between battery electric cars and conventional vehicles narrowed to just 25%. Therefore, Chinese manufacturers achieve price parity with internal combustion engines in Thailand and approach competitive pricing across Latin America.

Regional Manufacturing Expansion Promises Further Cost Reductions

Local production capacity remains minimal, with only 5% of EVs sold in emerging markets produced regionally currently. GWM and BYD plan to establish factories in Latin America by late 2026, potentially driving down costs further. As a result, these manufacturing facilities will bypass import tariffs while reducing transportation costs for the expanding Latam EV market.

Regional battery material demand will surge as local EV production scales rapidly across Latin America. Lithium, cobalt, nickel, and other critical minerals consumption will increase substantially to support growing battery manufacturing requirements. However, Latin America possesses significant lithium reserves, particularly in Argentina, Bolivia, and Chile, creating opportunities for vertical supply chain integration.

Global EV sales exceeded 17 million units in 2024, capturing 20% market share worldwide. The IEA projects 2025 sales will surpass 20 million units, representing over 25% of global automotive sales. Consequently, the Latam EV market expansion contributes meaningfully to this accelerating global electrification trend.

The Metalnomist Commentary

The Latam EV market boom signals a fundamental shift in global battery materials demand geography, with Chinese manufacturers leveraging cost advantages to penetrate price-sensitive emerging markets. This expansion will create substantial new demand for lithium, cobalt, and nickel while potentially enabling Latin America to capture more value from its abundant critical mineral resources through local processing and battery manufacturing integration.

EU EV Transition Faces Energy Cost and Trade Policy Pressure

EU energy

EU EV transition plans are facing growing pressure from high energy costs, tougher global competition and a regulatory model that industry leaders say may be weakening Europe’s automotive position. Speakers at the FT Future of the Car Summit warned that Europe must rethink how it competes with China and other industrial economies.

EU EV transition policy has relied heavily on regulation, including the planned 2035 phase-out of new internal combustion engine car sales. But carmakers and suppliers argue that regulation alone cannot deliver a competitive electric vehicle industry if energy prices, subsidies and supply-chain costs remain unfavourable.

EU EV transition challenges are becoming more visible as Chinese automakers gain share in Europe, southeast Asia and Latin America. Chinese producers have built cost-competitive EV platforms through subsidies, domestic competition, supply-chain control and fast industrial scaling.

The debate matters for metals because slower or more expensive electrification can reshape demand for lithium, nickel, cobalt, manganese, copper, aluminium and rare earth magnets. Automotive materials demand will still grow, but the path may become less direct and more exposed to policy choices.

China’s EV Scale Forces Europe to Rethink Trade Strategy

European automotive suppliers are calling for a more realistic approach to global competition. The industry is facing rivals that operate under different labour, subsidy and industrial policy conditions.

China has become one of the world’s strongest EV exporters. It accounted for around 40% of global EV exports in 2024, while leading Chinese brands have expanded aggressively with lower-cost, technology-rich vehicles.

This creates a competitive problem for European carmakers. Europe has focused on setting strict emissions targets, while China has focused on making EVs cheaper, scalable and export-ready.

Several industry executives now argue that collaboration may become unavoidable. Western manufacturers may need to partner with Chinese or other international competitors that already have a technological lead in EV platforms, batteries, software and power electronics.

This could change European supply chains. Rather than developing every technology internally, carmakers may increasingly combine European assembly and branding with externally sourced EV systems.

That strategy could support faster electrification, but it also creates dependence on imported components, battery materials and processed inputs. It may help automakers compete on cost, but it does not solve Europe’s strategic materials vulnerability.

Energy Costs Could Slow Consumer Adoption and Metals Demand

High charging and energy costs are another major barrier to Europe’s EV push. If consumers face much higher charging costs than drivers in China or other regions, the economic case for EV adoption weakens.

This is critical because EV demand is highly sensitive to total ownership cost. Batteries may become cheaper, but charging costs, highway tariffs and energy price volatility can still shape consumer decisions.

For battery metals, this matters directly. Slower EV adoption would reduce the speed of demand growth for lithium, nickel, cobalt and manganese, especially in full battery electric vehicles with large battery packs.

Copper and aluminium remain better positioned across multiple automotive pathways. EVs require copper for wiring, motors, charging systems and power electronics, while aluminium supports lightweighting, battery enclosures and structural components.

However, Europe’s automotive metals demand will increasingly depend on which technology mix wins. Full BEVs support larger battery metals demand, while hybrids and lower-cost EV platforms could shift consumption toward smaller batteries, more electronics and continued use of conventional automotive materials.

The policy challenge is therefore industrial as much as environmental. Europe must reduce emissions while keeping manufacturing competitive, securing raw materials and lowering energy costs for consumers.

If Europe cannot align regulation, energy prices and trade strategy, its EV transition could become a market for imported vehicles rather than a platform for domestic industrial growth.

The Metalnomist Commentary

Europe’s EV problem is not only about regulation or consumer demand. It is about whether the region can build a cost-competitive industrial system around energy, materials, technology and trade before Chinese EV platforms define the market.

Ford Expands EV Production with Cologne Battery Facility

Ford has begun mass assembly of electric vehicle battery packs at its Cologne, Germany plant, marking a major step in the automaker’s $2bn European electrification strategy. The facility will directly align with Ford’s nearby Cologne Electric Vehicle Center, enabling integrated production of the Capri and Explorer EV models, which will deliver ranges of up to 627km and 602km.

The highly automated production line, spanning 2km, uses 180 robots to weld, glue, and assemble the battery housing. Each battery pack consists of 2,775 individual parts and up to 12 modules, underscoring Ford’s commitment to advanced manufacturing efficiency and scale.

Strategic Supply Agreements for EV Battery Materials

Ford has also secured long-term supply deals to ensure stable access to critical materials. In October 2024, LG Energy Solution signed a contract to deliver 109 GWh of batteries from 2026, with terms extending up to six years. Meanwhile, US specialty chemicals firm Albemarle agreed to supply over 100,000 tonnes of lithium hydroxide between 2026 and 2030.

These partnerships highlight Ford’s focus on securing raw materials essential for its EV expansion. The agreements align with global trends of automakers locking in lithium and battery supply to mitigate price volatility and ensure future production capacity.

The Metalnomist Commentary

Ford’s Cologne investment reflects the growing importance of localized EV battery production in Europe. By integrating supply agreements with global partners, Ford strengthens its resilience against supply chain disruptions. This strategy not only supports its electrification roadmap but also places it in direct competition with European and Asian automakers accelerating EV deployment.

Gotion Foresees Lithium-Iron-Phosphate Batteries Dominating Global EV Market

In a significant shift for the electric vehicle (EV) industry, Gotion, a leading Chinese battery manufacturer, predicts that lithium-iron-phosphate (LFP) and lithium-manganese-iron-phosphate (LMFP) battery chemistries will dominate the global EV battery market within the next two to five years. Speaking at the ASEAN Battery Technology Conference in Singapore on August 21, Gotion's Asia-Pacific president, Cheng Qian, projected that these battery types could account for nearly 70 percent of the global market share, with the remainder being held by nickel-cobalt-manganese (NCM) batteries.

Qian emphasized that LFP battery technology is poised to take over the entire energy storage system sector, surpassing even the International Energy Agency's (IEA) forecast of 80 percent dominance. He attributed this trend to advancements in LFP battery range and the increasing demand for faster charging capabilities among EV consumers. NCM batteries, he noted, would be relegated to use in high-performance and ultra-long-range vehicles.

The transition has already begun to impact the nickel market and is gaining momentum among South Korean battery manufacturers. These companies are anticipating strong demand for more affordable EVs, driven by the cost-effectiveness of LFP batteries. Samsung SDI and SK On, for instance, are preparing to launch mass production of LFP batteries by 2026.

Adding to this momentum, LG Energy Solution (LGES) recently secured a contract to supply 39GWh of LFP batteries to Renault's EV division, Ampere, from its largest battery plant in Europe for the period 2025-2030. LGES is also planning to shift to LFP batteries for a U.S. energy storage project after initially supplying NCM batteries.

Expansion into Two-Wheeler Market

Gotion also predicts a significant shift toward LFP and LMFP batteries in the global two-wheeler EV market, which has been predominantly powered by NCM batteries. Cost reductions will be crucial for major two-wheeler markets in the Asia-Pacific region, including India, Indonesia, and Thailand, Qian noted.

India, which experienced a 30 percent surge in two-wheeler EV sales during its fiscal year 2023-24, reaching a record high of 944,126 units, is poised for further growth. Indonesia is similarly ambitious, aiming to deploy 2 million electric motorcycles by 2025, escalating to 13 million by 2030. The nation has introduced a $458 million subsidy program to incentivize electric motorcycle adoption.

The Philippines has also outlined its EV roadmap, emphasizing the lower upfront costs of electric tricycles and motorcycles as key drivers for EV adoption. The country aims to achieve a 50 percent share of electric motorcycles and tricycles by 2030, increasing to 60 percent by 2040.

Hyundai Motor Group announced the completion of its electric vehicle (EV) battery plant in collaboration with LG Energy Solution in Indonesia. This development marks a significant step in establishing a fully-integrated EV production system in the Southeast Asian nation. The Hyundai LG Indonesia Green Power (HLI Green Power) battery plant, located in Karawang New Industry City, will supply battery cells for the mass production of the KONA Electric EV at Hyundai's local manufacturing plant starting this month.

The establishment of this plant enables Hyundai to leverage a local, integrated production system, enhancing its strategic position in the Southeast Asian EV market. Production at HLI Green Power began in the second quarter of this year.

A grand completion ceremony was held, attended by 300 dignitaries, including Indonesian President Joko Widodo and key officials from both nations. Hyundai Motor Group's executive chair Euisun Chung highlighted the collaboration’s success in his speech, emphasizing the joint efforts in shaping the future of the EV ecosystem globally.

HLI Green Power, spanning 320,000 square meters, boasts advanced facilities with an annual output capacity of 10 gigawatt-hours, supporting over 150,000 EVs. The battery cells will be utilized not only in Hyundai’s Indonesian plant but also in various Hyundai and Kia models worldwide. Following the Ioniq 5, the KONA Electric is expected to significantly impact the Indonesian EV market.

Indonesia aims to achieve carbon neutrality by 2060 and plans to produce 600,000 EVs by 2030. Hyundai Motor Group is committed to furthering cooperation with Indonesia in other innovative areas, including hydrogen solutions and future air mobility.

Indonesia Battery Ecosystem Project Moves Forward With New Chinese Partnership

Aneka Tambang

The Indonesia battery ecosystem project is moving into a new phase with a fresh Chinese partnership. Antam, Industri Baterai Indonesia, and HYD Investment signed a framework agreement to develop an integrated battery ecosystem in Indonesia. This follows the exit of LG Energy Solution in 2025. As a result, the Indonesia battery ecosystem project remains alive and strategically important.

The change in partners matters because the project scale remains significant. Antam said the planned investment value is around $5-6 billion. A joint feasibility study will now define the next steps. Therefore, the Indonesia battery ecosystem project is shifting from partner transition into renewed execution planning.

HYD brings a strong industrial base to the table. The consortium includes Zhejiang Huayou Cobalt, EVE Energy, and Daaz Bara Lestari. That mix adds processing, battery, and investment capability. Consequently, the project gains a broader foundation across the battery value chain.

Indonesia Nickel Battery Chain Expands From Ore to Cells

The Indonesia nickel battery chain is central to this project’s logic. Planned facilities include an RKEF plant with 100,000 t/yr of nickel metal equivalent capacity. The project also includes an HPAL plant with 50,000 t/yr of nickel metal equivalent capacity. Therefore, upstream and midstream nickel conversion remain core pillars.

The downstream ambition is equally important. The project is expected to produce 105,000 t/yr of precursors and 30,000 t/yr of cathode materials. It also aims to build 20 GWh per year of nickel-based battery capacity. As a result, the Indonesia battery ecosystem project goes well beyond raw material processing.

Battery recycling also appears in the plan. The proposed recycling capacity is capped at 10,000 t/yr. That addition supports a more circular industrial model. Meanwhile, Antam will supply the nickel ore required for the project.

Antam Battery Project Reinforces Indonesia’s Downstream Strategy

The Antam battery project fits directly into Indonesia’s long-term downstream policy. Jakarta wants to build a local battery industry from mining to refining to final battery production. This new agreement supports that goal with another large integrated platform. Therefore, the project has national strategic value, not just commercial relevance.

This also shows Indonesia’s flexibility in partner management. LGES may have exited, but the broader industrial objective did not disappear. Instead, the project has been restructured around a new consortium. As a result, Indonesia continues pushing its battery ambitions despite partner turnover.

Antam’s role is becoming even more central. The company is involved in this project and also has a separate EV battery joint venture with CATL. That CATL-linked venture is expected to start operations by 2026. Consequently, Antam is emerging as one of the key anchors in Indonesia’s nickel battery chain.

The Metalnomist Commentary

This partnership matters because it shows Indonesia’s battery strategy is bigger than any one foreign partner. The country is still determined to convert nickel strength into downstream battery power. If execution improves, Indonesia could become one of the most integrated battery manufacturing hubs outside China.

Lithium-Ion Battery Copper Foil Shipments Surge as Ultra-Thin Products Gain Share

Copper Foil

Lithium-ion battery copper foil shipments rose sharply in 2025 as global battery production expanded and manufacturers shifted toward thinner materials to reduce copper costs. Global shipments reached 1.302mn t, up 41.7% from 2024, according to Chinese research institute EV Tank.

Lithium-ion battery copper foil demand remains closely tied to electric vehicle and energy storage growth. Copper foil is a key current collector in lithium-ion batteries, making it essential to cell performance, energy density and manufacturing cost.

Lithium-ion battery copper foil shipments were dominated by China, which accounted for 82.9% of global deliveries in 2025. EV Tank expects global shipments to reach 2.615mn t by 2030, implying continued expansion as battery output scales.

The product mix changed quickly during the year. The share of 8μm foil declined, while 6μm remained the mainstream product and accounted for more than 70% of total shipments.

Ultra-Thin Foil Gains Momentum on Copper Cost Pressure

Ultra-thin copper foil gained share as battery producers looked for ways to reduce copper input costs. Persistently high global copper prices pushed cell manufacturers to use thinner foil while maintaining battery performance.

The combined share of 5μm and 4.5μm ultra-thin foil rose to 24% in 2025. This is a major shift for a material category that requires tighter production control, better surface quality and stronger consistency.

Thinner copper foil can help reduce battery weight and improve energy density. It also lowers the amount of copper used per cell, which becomes increasingly important when copper prices remain elevated.

EV Tank expects 5μm and thinner foil to become a key material for high-end batteries. This reflects the industry’s move toward lighter, higher-energy-density cell designs.

However, thinner foil also raises manufacturing difficulty. Producers must control pinholes, tensile strength, elongation, surface roughness and coating compatibility more precisely.

That technical barrier could separate higher-end suppliers from lower-cost producers. As battery customers shift toward thinner grades, qualification and process reliability will become more important than simple capacity.

China Leads Supply as Competition Intensifies

China’s 82.9% share of global shipments shows its dominant role in battery copper foil supply. The country has built large-scale capacity around its lithium-ion battery ecosystem, supported by domestic EV, energy storage and cell manufacturing growth.

Competition intensified in 2025 as the market recovered and producers brought earlier-built capacity on line. This created a more fluid ranking among suppliers.

Longdian Wason ranked first with a 12.2% market share. Huachuang New Material followed after capacity ramp-ups lifted output and sales.

Defu Technology and Jiayuan Technology ranked third and fourth, respectively. Seven companies in the top 10 changed positions during the year, showing how quickly capacity, customer access and product mix are reshaping the sector.

Battery makers also increased procurement from second-tier suppliers to improve supply stability. This suggests buyers are trying to diversify supplier bases rather than rely only on leading producers.

For copper markets, the trend is strategically important. Battery copper foil growth creates a direct link between copper demand and battery technology. But the move toward ultra-thin foil also means battery growth will not translate into copper demand on a simple one-to-one basis.

The sector is therefore entering a more technical phase. Volume growth remains strong, but material intensity, foil thickness, supplier qualification and copper price pressure will all shape future demand.

The Metalnomist Commentary

The copper foil market shows how battery growth can lift copper demand while also forcing material thrift. High copper prices are pushing battery makers toward thinner foil, making technology and process control as important as raw capacity.

Volkswagen ID.4 Production Halt Shows US EV Demand Pressure

Volkswagen EV

Volkswagen ID.4 production in the US will end as the German automaker shifts its Chattanooga, Tennessee, plant toward higher-volume internal combustion vehicle output. The decision reflects weaker electric vehicle demand in the US and the need to protect North American manufacturing utilisation.

Volkswagen said the EV market continues to challenge the industry and requires measured decisions. The company will stop producing the ID.4 at Chattanooga and begin assembling the all-new second-generation Atlas from mid-April 2026.

Volkswagen ID.4 production has been strategically important because the model is the company’s top-selling EV in the US. However, the ID.4 sold 22,373 units in 2025, far below the Atlas, which sold 71,044 units and remained Volkswagen’s second-best-selling model for the past three years.

The decision shows how automakers are adjusting production footprints as EV adoption slows. US EV sales fell by 27% year on year to 216,300 units in the first quarter, creating pressure on manufacturers to rebalance plant capacity, dealer inventory and product planning.

Chattanooga Shift Prioritises Higher-Volume SUV Demand

The Chattanooga plant will now focus on the second-generation Atlas, a three-row sport utility vehicle with much stronger US sales momentum. This gives Volkswagen a clearer volume base in a market where larger SUVs remain commercially attractive.

The move is not a full retreat from the ID.4. Volkswagen said model-year 2026 ID.4 vehicles will remain available through current inventory, supporting US demand into 2027. The company also plans a future version of the ID.4 for North America, although details have not yet been disclosed.

Still, the production shift is significant. Automakers rarely remove capacity from a model unless demand, margin or manufacturing strategy has changed. In this case, Volkswagen appears to be choosing a higher-volume SUV platform over a slower-moving EV in the near term.

This reflects a wider industry trend. EV demand has become more uneven as consumers respond to vehicle prices, charging access, policy uncertainty and changing incentive structures. Automakers now need more flexible production strategies rather than relying on straight-line EV growth forecasts.

EV Slowdown Could Weigh on Battery Materials Demand

Volkswagen ID.4 production changes also matter for the battery materials supply chain. Lower EV output can reduce near-term demand for lithium, nickel, graphite, manganese, copper, aluminium and rare earth magnet materials linked to electric drivetrains and battery systems.

The effect will not come from Volkswagen alone. The bigger issue is that several automakers are reassessing EV production rates in response to slower consumer adoption. If this pattern continues, battery material demand growth may become more volatile than earlier industry forecasts suggested.

For suppliers, the shift creates a timing problem. Many battery, cathode, anode and recycling investments were planned around rapid EV market expansion. Slower model-level output can leave material producers exposed to weaker offtake, lower utilisation and price pressure.

At the same time, Volkswagen’s decision does not eliminate long-term EV demand. It shows that the transition may move in phases, with automakers balancing EVs, hybrids and combustion vehicles depending on regional demand. North America may therefore remain a more mixed powertrain market than China or parts of Europe.

The Metalnomist Commentary

Volkswagen’s ID.4 decision shows that EV strategy is now being tested by real factory economics. The energy transition is still moving forward, but automakers will increasingly prioritise models that protect utilisation, margins and supply-chain stability.

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.
