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.

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.

China LFP Supply Deal Between Wanrun and CATL Secures 1.32 Million Tonnes

Wanrun

China LFP supply deal reached historic proportions as Hubei Wanrun New Energy Technology signed a five-year agreement to deliver 1.32 million tonnes of lithium-iron-phosphate cathode materials to CATL. The massive China LFP supply contract from May 2025 through May 2030 represents one of the largest battery materials procurement agreements in the industry, highlighting CATL's aggressive expansion strategy and LFP technology's growing market dominance.

Strategic Partnership Drives Battery Technology Innovation

China LFP supply partnership extends beyond simple procurement to encompass joint research and development initiatives. Wanrun and CATL agreed to collaborate on high-density LFP product iteration and mass production capabilities while jointly exploring new energy market opportunities. CATL committed to purchasing at least 80% of promised monthly quantities, providing Wanrun with guaranteed revenue streams and production planning certainty.

Meanwhile, Wanrun demonstrated strong operational performance with 2024 LFP production reaching 233,108 tonnes, representing 51% growth from 2023. Sales volumes increased 39% to 228,240 tonnes during the same period, reflecting robust market demand and the company's expanding manufacturing capabilities. This performance trajectory supports the substantial supply commitments made to CATL.

CATL's Market Leadership Drives Demand Growth

However, CATL's explosive growth trajectory necessitates secured raw material supplies for sustained market expansion. The battery giant sold 120 GWh of batteries in Q1 2025, marking 30% year-over-year growth and reinforcing its position as China's largest battery producer. CATL raised $4.6 billion through Hong Kong Stock Exchange share sales on May 20th, specifically targeting global battery market expansion financing.

Therefore, the Wanrun supply agreement aligns perfectly with CATL's international growth strategy and capital deployment plans. The five-year commitment provides production stability while supporting CATL's aggressive capacity expansion across multiple global markets. This strategic partnership model demonstrates how Chinese battery companies integrate vertically to secure critical material supplies.

LFP Technology Gains Global Market Share

Furthermore, lithium-iron-phosphate batteries captured nearly half of the global electric vehicle battery market in 2024 according to the International Energy Agency. LFP technology offers significant advantages including lower manufacturing costs and enhanced safety performance compared to ternary battery alternatives. These benefits drive increasing adoption across automotive manufacturers seeking cost-effective energy storage solutions.

As a result, the Wanrun-CATL partnership positions both companies advantageously within the rapidly expanding LFP segment. China's dominance in LFP production creates competitive advantages for domestic battery manufacturers while supporting the country's electric vehicle industry leadership. The supply agreement reinforces China's integrated approach to battery supply chain control from raw materials through finished products.

The Metalnomist Commentary

The Wanrun-CATL supply agreement exemplifies China's systematic approach to battery supply chain integration, securing critical materials access while driving technology innovation through strategic partnerships. This 1.32 million tonne commitment reflects both companies' confidence in LFP technology's long-term market prospects and China's continued dominance in global battery manufacturing despite increasing international competition.

Toyota Tsusho PPESNA Stake Strengthens North American Battery Supply Chain

Toyota Tsusho

Toyota Tsusho PPESNA stake acquisition gives the Japanese trading firm a stronger role in building Toyota Group’s North American battery supply chain. The company acquired a 20% stake in Prime Planet Energy and Solutions’ North American subsidiary, PPESNA.

The Toyota Tsusho PPESNA stake is designed to support stable battery production across procurement, materials, components, production equipment and recycling. The move shows how Japanese industrial groups are deepening control over regional battery supply chains as North American electrification investment expands.

PPESNA was established in September 2025 to improve service and response capabilities for PPES customers and Toyota Group’s battery business in North America. Toyota Tsusho’s investment gives the subsidiary a broader commercial and supply-chain platform.

Toyota Tsusho Targets Battery Procurement and Recycling Integration

Toyota Tsusho said the investment will help develop a supply chain covering equipment procurement, battery materials, components and recycling. This is important because battery production increasingly depends on coordinated sourcing across cathode materials, anode materials, separators, electrolytes, cells, modules and recycling routes.

The company already has exposure to Toyota Battery Manufacturing North Carolina, which can produce 30GWh/yr of batteries at full capacity. That gives Toyota Tsusho a direct link to one of Toyota Group’s key North American battery manufacturing assets.

The Toyota Tsusho PPESNA stake also complements the company’s recycling strategy. Toyota Tsusho has established a joint venture with LG Energy Solution to recycle batteries in North Carolina, giving it another position in the circular battery materials chain.

North America Becomes a Strategic Battery Manufacturing Base

North America is becoming a core region for Japanese battery supply-chain investment. Automakers and trading houses are trying to localise procurement, reduce logistics risk and prepare for tighter regional content requirements.

Toyota Tsusho’s role is especially important because trading companies often connect raw materials, equipment suppliers, manufacturers and recyclers. In battery supply chains, that coordination can reduce bottlenecks and improve long-term production stability.

For Toyota Group, the PPESNA investment supports a more integrated North American platform. It links battery production, upstream procurement and recycling at a time when battery costs, material security and regional manufacturing incentives remain central to electric vehicle competitiveness.

The Metalnomist Commentary

Toyota Tsusho’s PPESNA investment shows that battery competitiveness is moving beyond cell production alone. The real advantage will come from controlling the full supply chain, from equipment and materials procurement to recycling and closed-loop recovery.

Ronbay Secures Major Sodium-Ion Battery Cathode Order, Strengthening Market Presence

Ningbo Ronbay

Expanding Sodium-Ion Battery Cathode Production

Ningbo Ronbay, a leading Chinese battery cathode active material (CAM) manufacturer, has secured a 3,000-tonne order for sodium-ion battery cathode material from an undisclosed client. The company announced the deal on January 20, reinforcing its position as a key player in China’s sodium-ion battery market.

Ronbay has been heavily investing in sodium-ion cathode materials, committing 3 billion yuan ($413 million) in September 2023 to construct a 50,000-tonne-per-year production complex, which is set to launch by 2026. This investment aligns with the growing global demand for sodium-ion batteries, expected to reach 23GWh in 2025.

China’s Sodium-Ion Battery Industry Gains Momentum

China’s leading battery manufacturers, including CATL, BYD, and Hithium, have accelerated their sodium-ion battery production. BYD, for example, started construction on a 30 GWh per year sodium-ion battery plant in Xuzhou, Jiangsu province, in early 2024. These expansions indicate increasing market confidence in sodium-ion battery technology, particularly for two-wheeled and three-wheeled vehicles, energy storage, and power applications.

The Chinese government has also actively promoted sodium-ion battery development as part of its 2021-2025 energy strategy, emphasizing the battery’s cost advantages, resource abundance, and environmental benefits compared to lithium-ion batteries. However, despite strong governmental backing, sodium-ion battery shipments in 2024 fell short of earlier expectations due to higher manufacturing costs compared to lithium-ion and lead-acid batteries, according to Chinese research institution EV Tank.

Ronbay’s Role in the Growing Sodium-Ion Market

With this latest order, Ronbay strengthens its leadership in sodium-ion cathode production, ensuring steady market growth despite industry challenges. The company’s large-scale investment and expanding production capacity position it to capitalize on rising sodium-ion battery adoption while supporting China's push for alternative battery technologies.

As demand for low-cost and sustainable energy storage solutions rises, sodium-ion batteries could play a crucial role in diversifying the global battery supply chain, particularly as a viable alternative to lithium-ion technology.

Nth Cycle Trafigura Battery Materials Deal Signals Scale-Up in Black Mass Refining

Nth Cycle

Nth Cycle Trafigura battery materials deal marks a significant step for recycled battery metals supply as the US critical metals refiner prepares to expand its refining footprint. Nth Cycle has signed a 10-year binding offtake agreement to supply Trafigura with battery materials valued at $1.1bn.

The agreement covers 2,000 metric tonnes of contained nickel in mixed hydroxide precipitate and 1,500 tonnes of lithium carbonate. These materials will be refined from 12,000 tonnes of black mass, reinforcing the growing commercial role of recycled feedstock in the battery supply chain.

The Nth Cycle Trafigura battery materials deal also gives Trafigura long-term exposure to recycled nickel and lithium units. That matters as battery manufacturers, automakers, and trading houses seek lower-carbon and more traceable alternatives to mined raw materials.

Modular Refining Model Targets Faster Battery Materials Capacity

Nth Cycle plans to establish new operations in South Carolina and the Netherlands, with production scheduled to begin in 2028. The dual-location strategy gives the company access to both North American and European battery supply chains.

The company’s modular refinery system is designed to reduce build time and capital intensity. This model could become important because conventional refining projects often face long development timelines, high upfront costs, and permitting delays.

Black mass refining is becoming a strategic bridge between battery recycling and primary raw material supply. By converting battery waste into mixed hydroxide precipitate and lithium carbonate, refiners can return critical metals into the battery value chain with less dependence on new mining projects.

Trafigura Offtake Strengthens Commercial Validation

The Nth Cycle Trafigura battery materials deal provides commercial validation for Nth Cycle’s refining technology and expansion plan. A 10-year offtake agreement with a major global trading house can support financing, customer confidence, and project execution.

Nth Cycle has also received a €7.5mn grant from the Netherlands’ National Growth Fund under the Critical Raw Materials Lion initiative. This support highlights Europe’s policy focus on domestic and regional critical raw materials capacity.

The agreement reflects a broader shift in battery materials markets. Recycled nickel and lithium are moving from pilot-scale sustainability claims toward bankable supply contracts. As a result, black mass is increasingly becoming an industrial feedstock rather than a waste stream.

The Metalnomist Commentary

This deal shows that battery recycling is entering a more serious commercial phase. The key challenge for Nth Cycle will be execution, because long-term offtake value only matters if modular refining can deliver consistent volume, quality, and cost performance.

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.

Electra Cobalt Offtake Extension Secures LG Energy Solution’s Battery Supply

Electra

Electra cobalt offtake terms have been extended by LG Energy Solution, giving the South Korean battery maker longer access to battery-grade cobalt sulfate from Canada. The updated agreement shows how battery manufacturers continue to secure regional critical mineral supply even as cobalt demand faces changing battery chemistry trends.

Under the revised deal, LG Energy Solution will take 60% of Electra Battery Materials’ cobalt sulfate production through 2029. The agreement also includes an option to extend the offtake terms to 2032. LGES first agreed in 2022 to buy battery-grade cobalt sulfate from Electra for three years.

The Electra cobalt offtake update is strategically important because it supports a North American refining route for battery materials. Electra is developing a cobalt sulfate refinery in Ontario, Canada, with commercial production expected in the fourth quarter of 2027.

Ontario Refinery Becomes Key to Regional Cobalt Processing

Electra’s Ontario cobalt refinery has faced delays, but the project is now moving forward again. Financial constraints and supply chain disruptions paused construction in 2023, before Electra restarted work in November after approving a $73 million construction budget.

The company expects early commissioning to begin in the fourth quarter of 2026. Commercial production is planned for the fourth quarter of 2027. Once operating, the refinery is expected to initially produce 5,120 tonnes per year of contained cobalt.

Electra’s nameplate capacity could reach up to 6,500 tonnes per year of contained cobalt. This scale would not transform global cobalt supply alone, but it could provide an important regional source of battery-grade cobalt sulfate for North American and allied battery supply chains.

LGES Strengthens Critical Mineral Security Through Long-Term Supply

LG Energy Solution’s extended agreement shows that battery makers still value secure cobalt supply despite growth in lower-cobalt and cobalt-free chemistries. High-nickel battery systems and certain performance-focused applications continue to require reliable cobalt inputs.

The Electra cobalt offtake deal also supports supply chain diversification away from highly concentrated refining regions. For LGES, Canadian cobalt sulfate could help reduce procurement risk and support compliance with regional sourcing expectations in North America.

For Electra, the updated agreement strengthens commercial visibility before the refinery reaches production. Long-term offtake support can help improve project bankability, especially for critical mineral processing assets that require high capital spending before revenue begins.

The Metalnomist Commentary

The Electra-LGES deal shows that cobalt has not disappeared from battery supply strategy. Even as chemistries diversify, battery-grade refining capacity in North America remains strategically valuable for automakers, cell makers, and policy-driven supply chains.

Brunp Battery Materials Project Expands CATL’s Recycling and LFP Supply Chain

Brunp Battery Materials

Brunp battery materials project development has advanced in Yichang, Hubei province, as Guangdong Brunp Recycling Technology broke ground on a 500,000 t/yr production complex. The project carries total investment of 6.1bn yuan, or about $840 million.

The new plant is designed to produce 300,000 t/yr of iron phosphate, 180,000 t/yr of nickel sulphate and 12,000 t/yr of cobalt sulphate. Construction is scheduled for completion in the second half of 2027.

Brunp battery materials project investment strengthens the upstream materials platform behind China’s battery industry. Brunp is a controlling subsidiary of CATL, the country’s largest battery producer, and focuses on recycling, resources and battery materials.

Yichang Base Builds Scale Across LFP and Recycling

The Yichang base will become a major integrated battery materials hub once the new project is operational. It will have 750,000 t/yr of iron phosphate capacity, 450,000 t/yr of lithium iron phosphate capacity and 500,000 t/yr of battery recycling capacity.

Brunp has already made several investments in Yichang since entering the city in 2021. The company launched a 450,000 t/yr LFP factory in December, reinforcing the site’s role in China’s expanding phosphate-based battery supply chain.

This matters because LFP batteries continue to gain share in electric vehicles and energy storage systems. Large-scale iron phosphate and LFP capacity gives CATL-linked supply chains stronger control over cost, material availability and recycling integration.

Recycling Capacity Deepens China’s Battery Materials Control

Brunp Recycling processed more than 200,000t of power batteries in 2025. The company now plans to raise total recycling and processing capacity to more than 1mn t/yr by 2030.

The strategy reflects a wider shift in battery materials sourcing. Recycling is becoming a strategic source of nickel, cobalt, lithium and other battery inputs, especially as governments and manufacturers seek lower-carbon and more secure supply chains.

The Yichang project also adds nickel sulphate and cobalt sulphate capacity, linking recycling with precursor material production. However, weaker upside in metals prices has limited buyer appetite in China’s black mass market, even as NCM payables edged higher in early March.

The Metalnomist Commentary

Brunp’s Yichang expansion shows how CATL is tightening control over the full battery materials loop, from recycling to LFP and sulphate production. The project also underlines China’s advantage in building scale across both primary materials processing and circular battery supply chains.

EnerSys Tijuana Battery Plant Closure Shifts Production to US TPPL Facility

EnerSys

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

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

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

TPPL Technology Strengthens EnerSys’ Domestic Manufacturing Position

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

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

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

Tariff Risk and Tax Benefits Reshape Battery Supply Chains

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

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

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

The Metalnomist Commentary

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

Element 25 Butcherbird Manganese Expansion Gains Funding for Battery Supply Chain

Element 25

Element 25 Butcherbird manganese expansion has moved forward after the Australian metals producer raised $18mn in equity to support the next phase of mine growth. The funding will help expand manganese concentrate output from the Butcherbird mine in Western Australia.

The project is expected to triple Butcherbird’s manganese concentrate production to 1.1mn t/yr from 365,000 t/yr. Full mechanical completion and commissioning are expected in the first quarter of 2027.

Element 25 Butcherbird manganese expansion is strategically important because the mine will supply feedstock for the company’s planned battery-grade manganese sulphate refinery in Louisiana. That project links Australian ore supply with US battery materials processing.

The expansion also strengthens Element 25’s role in the electric vehicle supply chain. The company already has offtake agreements with General Motors and Stellantis, giving the project direct exposure to automaker demand for non-China battery materials.

Butcherbird Expansion Builds Manganese Feedstock Scale

Western Australia’s state government approved the Butcherbird expansion in March 2025. The mine is expected to operate for at least 18 years, giving Element 25 a long-term feedstock platform.

The planned increase to 1.1mn t/yr of manganese concentrate would materially change the scale of the operation. Higher concentrate output should support downstream conversion into battery-grade manganese sulphate while also leaving room for sales into traditional steel markets.

Manganese remains a key steelmaking input because it improves strength and toughness. Element 25 plans to sell excess concentrate to steelmakers, creating a secondary demand channel outside batteries.

However, the main strategic value is in batteries. Manganese is increasingly important for lithium-ion battery chemistries as automakers seek lower-cost, more secure and less cobalt-dependent cathode materials.

Louisiana Refinery Links Australia to US Battery Materials Policy

Element 25’s manganese concentrate will mainly feed its battery-grade high-purity manganese sulphate monohydrate facility in Louisiana. The refinery is planned for 135,000 t/yr of production capacity.

The US government backed the Louisiana refinery with a $166mn grant in January last year. This support reflects Washington’s effort to build domestic processing capacity for battery materials and reduce reliance on China-controlled supply chains.

The Australian government also opened a A$50mn loan package in June to support the Butcherbird expansion. Together, the US and Australian support show how allied governments are trying to connect mining, refining and EV manufacturing supply chains.

Element 25 Butcherbird manganese expansion therefore fits a broader industrial strategy. Australia provides the resource base, while the US builds refining capacity closer to automakers and battery manufacturers.

The project’s success will depend on execution at both ends of the chain. Butcherbird must deliver concentrate at scale, while Louisiana must convert that material into battery-grade sulphate that meets customer specifications.

The Metalnomist Commentary

Element 25’s project shows how manganese is moving from a steelmaking material into a strategic battery supply input. The key challenge will be proving that mine expansion and US chemical refining can scale together on the timeline automakers require.

China's LMFP Battery Plant Boosts Cathode Material Market

Battery LFP

China’s LMFP battery materials sector takes a leap forward with Shanxi Tewashi’s 100,000 t/yr plant launch.

China’s Shanxi Tewashi Energy has officially started production at its new 100,000 t/yr lithium ferro-manganese phosphate (LMFP) cathode material plant. Located in Changzhi city, the facility is equipped with 16 fully automated production lines and marks a major investment in next-generation lithium-ion battery technology. The company, formed in late 2023, is a joint venture between Qianyun High-tech Energy and state-owned Shanxi Changgao Zhihui Group.

This launch further underscores China’s strategic focus on expanding domestic LMFP output. LMFP cathode materials offer higher energy density and lower costs compared to traditional lithium iron phosphate (LFP), making them attractive for electric vehicles. However, market analysts note that LMFP’s shorter cycle life and reduced discharge performance remain challenges for widespread adoption. Nevertheless, Chinese firms are doubling down on development. Major players like Hunan Yuneng and Ningbo Ronbay are building large-scale LMFP facilities to capture future market share.

The push into LMFP reflects China’s evolving battery supply chain strategy. As battery manufacturers aim to improve performance and reduce reliance on critical raw materials like nickel and cobalt, LMFP offers a viable alternative. With new LMFP projects launching across Shanxi, Hubei, and Gansu provinces, China is positioning itself as the global leader in diversified cathode active materials. The ramp-up of LMFP output may also influence global pricing dynamics for both LFP and emerging sodium-ion chemistries.

The Metalnomist Commentary

China's aggressive expansion of LMFP cathode production signals a pivot toward alternative battery chemistries. As the global EV sector seeks higher energy density at lower cost, Chinese manufacturers are racing to commercialize LMFP at scale—potentially reshaping the future of EV battery composition.

Intensifying Battery Competition in Asia Amid Evolving Market Dynamics

EV Battery

The Race for Dominance in the Lithium Iron Phosphate Battery Market

The competition among major battery producers, particularly between China and South Korea, is set to intensify in 2025. South Korean giants like LG Energy Solution (LGES), Samsung SDI, and SK On are aggressively pursuing mass production of lithium iron phosphate (LFP) batteries, a domain where Chinese manufacturers have traditionally excelled. These South Korean firms are targeting a mass production rollout by the latter half of 2025, aimed primarily at the electric vehicle (EV) market.

Strategic Market Expansion

South Korean battery manufacturers are not just competing on the product level; they are also strategically targeting markets in the US and Europe, regions where their Chinese competitors have been less successful. This move is particularly strategic given the recent failure of Northvolt in Europe, which previously held a significant share of the European battery production capacity. The potential rollback of the US Inflation Reduction Act (IRA) tax credits, however, poses a financial threat to these South Korean firms, particularly with the upcoming changes anticipated under the administration of US president-elect Donald Trump.

Challenges and Opportunities in Other Regions

Australia, on the other hand, is focusing on niche areas such as "stationary storage" battery production, despite facing significant challenges in its mining sectors, especially with nickel and lithium. The downturn in these industries has led to major setbacks, such as the closure of the Bald Hill site by Mineral Resources, prompting government intervention.

In Southeast Asia, countries like Indonesia and the Philippines are making notable advances. Indonesia, in collaboration with LGES and Hyundai Motor, has already commenced operations at a new battery production facility, while the Philippines has launched its first LFP battery plant, which began operations in October with the support of Australian investment firm StB Capital Partners.

Leclanché Introduces Niobium-Based Battery Cells for Industrial and Heavy-Duty EV Applications

Leclanché

Swiss energy storage company Leclanché is set to launch a new battery cell solution that leverages XNO, a niobium-based anode material developed by UK-based Echion Technologies. The XN50 battery cell will replace Leclanché’s current lithium titanium oxide (LTO) offering, with a focus on heavy-duty electric vehicles (EVs), rail, and marine applications.

The XN50 promises significant advancements over LTO cells, delivering 50% higher energy density and the ability to fast charge in under 10 minutes. Moreover, the niobium-based cells offer enhanced safety and performance, particularly in extreme weather conditions. These new cells will be available alongside Leclanché's existing nickel manganese cobalt (NMC) batteries, which use graphite anodes. Leclanché has been producing LTO cells since 2012 and introduced NMC batteries in 2019.

Niobium’s Growing Role in Battery Technology

Niobium, traditionally used in steel alloys and defense applications, is now becoming a key material in battery and fuel cell technologies due to its high energy density. Echion’s XNO materials, developed from mixed niobium oxide compounds and microparticle designs, are sourced from Brazilian niobium producer CBMM. The XN50 is the first battery cell to incorporate XNO on a commercial scale, offering manufacturers a cutting-edge solution for industrial and mass transportation use. Additionally, Echion has signed a deal with Taiwanese battery manufacturer GUS Technology to supply XNO for heavy-duty EV battery production.

As demand for niobium-based anode materials continues to rise, Echion plans to open a 2,000 t/yr XNO manufacturing facility this year to supply major cell manufacturers and original equipment manufacturers (OEMs). The versatility of niobium extends beyond batteries, with Canadian project developer NioBay Metals currently exploring niobium-titanium alloys for hydrogen fuel cells, presenting new market opportunities for niobium and titanium.

US Tariffs Could Boost Argentina’s Lithium Salts Production

Argentina Lithium

New Tariff Policies May Propel Argentina to the Forefront of Battery Materials Supply

US President Donald Trump’s new tariff measures, announced this week, could significantly impact the global lithium market. While many energy and mineral products, including lithium carbonate and lithium hydroxide, are exempt from new tariffs, the shift towards more localized battery production in the US could create new opportunities for Argentina's lithium sector. Argentina, with its lower-cost brine assets, could become a key player in the production of battery-grade lithium salts.

Shift in Global Battery Manufacturing and Tariffs Impact

Trump's recent tariff policy introduced significant duties on completed batteries from China, Japan, and South Korea. These duties are likely to accelerate the trend of localizing battery production in the US. Under the Inflation Reduction Act of former President Joe Biden’s administration, the US has already seen a shift toward local manufacturing, with major battery manufacturers like Panasonic, Samsung SDI, Ford, and Toyota planning to open around 10 new battery factories this year.

However, with a lack of domestic mining and processing capacity in the US, the country will increasingly rely on imports for raw materials to meet the demand for battery production. The US currently has only one operating lithium mine, Albemarle's Silver Peak mine in Nevada. Despite producing lithium carbonate and hydroxide, this mine cannot meet the higher purity standards required for battery-grade products needed in electric vehicles (EVs).

Argentina’s Competitive Edge in Lithium Salts Production

Argentina stands out due to its potential to produce high-quality, cost-competitive lithium salts. Brine operations in Argentina are expected to be more efficient and less costly than other South American and spodumene-producing countries. Although brine facilities require higher initial capital costs, their ongoing operational costs are lower than spodumene-based assets, making them an attractive option for global supply chains.

Argentina’s competitive advantage is further strengthened by its 3% royalty tax on lithium mining, compared to the 40% ceiling in Chile, which has a more developed lithium industry. Despite facing a 10% import tariff by the US, Argentina is well-positioned to expand its lithium production to meet the growing demand from battery factories in the US. According to Argentina’s Vice Minister of Energy and Mining, Daniel Gonzalez, "All of Argentina's lithium projects go to battery grade," signaling the country's commitment to producing high-purity lithium products.

While countries like Australia, Brazil, and some African nations rely on China for lithium processing, Argentina's direct production of battery-grade lithium offers it a strategic advantage in the global market.

ExxonMobil battery anode graphite deal signals new push into EV batteries

ExxonMobil

The ExxonMobil battery anode graphite deal marks a strategic shift toward advanced battery materials. The company will acquire the US assets and technology of Superior Graphite to gain a foothold in battery anode graphite. As a result, the ExxonMobil battery anode graphite deal aims to convert refining-derived carbon streams into higher value synthetic graphite products.

Synthetic graphite strategy builds on ExxonMobil refining strengths

ExxonMobil battery anode graphite deal execution leans heavily on the group’s refining skills and feedstock access. Synthetic graphite production can use carbon-rich streams from existing oil refineries, rather than rely on traditional mined graphite. Therefore, the company can integrate battery anode graphite manufacturing into current industrial sites with established utilities and logistics.

Producing synthetic graphite is also less labour intensive than conventional mining operations. This shift supports more predictable quality and supply for high performance battery anodes, especially for EV and energy storage systems. Meanwhile, Superior Graphite’s technology portfolio should help accelerate product qualification with cell manufacturers and automotive OEMs.

ExxonMobil expects demand for higher performance batteries and advanced graphite materials to grow significantly. As a result, the company views synthetic graphite as a natural extension of its downstream product chain. However, it still needs to prove that oil-to-anode economics can compete with incumbent graphite suppliers in Asia.

Energy transition focus must still compete for capital

The ExxonMobil battery anode graphite deal fits into a broader energy transition strategy built around familiar skill sets. The company is already investing in carbon capture, hydrogen and low-emission fuels that leverage existing process and project expertise. Therefore, battery anode graphite offers another pathway where ExxonMobil can combine scale, engineering and feedstock advantages.

Yet internal capital allocation remains disciplined and competitive. Management has repeatedly stressed that new technologies, including carbon capture and hydrogen, must compete with core oil and gas projects for investment. Likewise, the ExxonMobil battery anode graphite deal will need to deliver attractive returns against upstream and petrochemical options. This requirement could limit speed of expansion if market conditions or pricing weaken.

In addition, graphite remains a politically sensitive material within global battery supply chains. Western buyers seek alternatives to Chinese-dominated supply, but must balance cost, performance and ESG criteria. If ExxonMobil can demonstrate low emission synthetic graphite at scale, it may win premium contracts from OEMs under pressure to de-risk their anode sourcing.

The Metalnomist Commentary

ExxonMobil’s move into battery anode graphite shows how oil majors now seek value in critical mineral adjacencies rather than pure mining. Success will depend on whether integrated refinery-based synthetic graphite can match Asian competitors on cost and performance. Market participants should watch for offtake deals with cell makers, which will reveal how quickly this new graphite platform gains traction.

China's Graphite Market to Grow in 2025 Despite Oversupply and Geopolitical Challenges

China Graphite

China's graphite flake market is set to expand further in 2025, driven primarily by sustained demand from the new energy vehicle (NEV) industry. Despite challenges such as oversupply and geopolitical uncertainties, the market remains resilient due to the critical role of graphite in producing lithium-ion battery components like anodes.

The NEV industry, a major consumer of graphite, has grown exponentially in China over the past decade, supported by the country's decarbonization agenda. In 2023, NEV production reached 11.345 million units (up 35% year-on-year), with sales climbing 36% to 11.262 million units. By October 2023, NEVs accounted for 46.8% of China's auto market, up from 26% in 2022.

To meet rising demand, China's domestic graphite flake production increased from 930,000 tons in 2020 to 1.2 million tons in 2023. Major companies, such as China Minmetals Heilongjiang Graphite, have launched large-scale projects, including a 6 million tons/year graphite flake ore production complex. Additional capacity expansions are underway, including projects by Heilongjiang Ruitong, Heilongjiang Longda, and Inner Mongolia Hengyu.

Export Licensing Challenges and Geopolitical Headwinds

However, Beijing's introduction of export licensing controls on graphite products like flake and spherical graphite is curbing exports. From January to October 2023, Chinese graphite flake exports dropped 23% year-on-year to 49,647 tons. Exports to India plummeted to zero, compared with 9,379 tons in the same period last year, largely due to the new regulatory restrictions.

Exporters must now comply with stringent licensing procedures that require detailed documentation, including technical descriptions, end-user identity verification, and export contracts. This move aligns with China's broader export control legislation for dual-use items, which applies to goods that have both civilian and military applications.

China also reduced tax rebates for spherical graphite exports, an essential component in lithium-ion batteries, from 13% to 9%, effective December 1, 2023. Meanwhile, stricter inspections on US-bound graphite shipments reflect escalating trade tensions between the two countries. Policies such as the US Inflation Reduction Act and the EU's Critical Raw Materials Act are further encouraging global battery manufacturers to diversify supply chains away from China.

Global Battery Producers Adapt

In response to export restrictions and potential US tariff hikes, Chinese battery manufacturers are increasing overseas investments. BTR, a major battery material producer, recently launched an 80,000 tons/year anode material plant in Indonesia and began building additional facilities in Morocco. Similarly, Shijiazhuang Shangtai is investing $154 million to establish a 50,000 tons/year anode material plant in Malaysia.

Such initiatives are helping companies hedge against geopolitical risks while ensuring a stable supply of raw materials for the growing global battery market.

Uncertain Political Climate

Political developments, such as a potential re-election of Donald Trump as US president, could further disrupt the global electric vehicle (EV) market. Trump's policies favor traditional energy sources and could lead to increased tariffs on lithium-ion batteries and related raw materials. This uncertainty underscores the importance of diversifying supply chains and expanding overseas production.

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.

China's Battery Output, Installed Volumes Surge in 2024 Amidst NEV Boom

China Battery Production

LFP Batteries Dominate Market Share as CATL, BYD, CALB Lead Installations

China experienced a substantial increase in power and energy storage battery production and installed volumes in 2024, driven by the robust growth of the new energy vehicle (NEV) sector. Data reveals significant year-over-year growth, reinforcing China’s leading role in the global battery market.

LFP Batteries' Continued Market Dominance and Leading Producers

Lithium iron phosphate (LFP) batteries maintained their commanding market position, accounting for 74.4% of total production and 74.6% of installed volumes in 2024, as reported by the China Automotive Battery Innovation Alliance (CABIR). This underscores the strong preference for LFP batteries within China, primarily due to their cost-effectiveness and safety attributes.

The top three battery manufacturers, Contemporary Amperex Technology Co., Ltd. (CATL), BYD, and CALB, collectively installed a substantial 417.5 GWh of battery capacity in 2024. CATL led with 246 GWh, securing 45% of the market share, followed by BYD with 135 GWh (25%) and CALB with 36.5 GWh (7%). These companies are integral to the rapid expansion of China’s NEV industry.

The surge in battery demand is directly attributable to the explosive growth of China’s NEV market. According to data from the China Association of Automobile Manufacturers (CAAM), NEV production reached 12.888 million units in 2024, a 34% increase from the previous year, while sales rose by 36% to 12.866 million units.

PLS Lithium Phosphate Offtake Signals Shift Toward Midstream Battery Materials

PLS Lithium

PLS lithium phosphate offtake with China’s Ningbo Ronbay New Energy Technology marks a strategic step by the Australian lithium producer into higher-value battery materials. The agreement covers lithium phosphate from PLS’ midstream lithium refining demonstration plant.

PLS lithium phosphate offtake gives the company an early customer pathway as it tests whether spodumene can be converted into an intermediate chemical product with broader downstream appeal. The plant is scheduled to deliver first product in the third quarter of 2026.

PLS lithium phosphate offtake also links the company directly with Ronbay, one of the world’s largest lithium iron phosphate cathode material producers. Ronbay will provide technical support as PLS works to optimise product quality and specification.

The agreement’s price and volume details were not disclosed. But the pricing structure will broadly reference lithium chemical prices, with a proportional mechanism similar to spodumene pricing.

Lithium Phosphate Could Shorten the LFP Supply Chain

PLS’ demonstration plant is designed to produce more than 3,000 t/yr of lithium phosphate. It will consume about 27,000 t/yr of spodumene.

The company took full ownership of the plant from former joint-venture partner Calix in February. That gives PLS more control over the development route as it moves beyond conventional lithium concentrate sales.

The strategic importance lies in the possible use of lithium phosphate as a direct feedstock for LFP cathode production. Some LFP cathode producers are testing lithium phosphate instead of lithium carbonate because it could shorten processing steps and reduce total production costs.

This matters because LFP batteries are gaining share in electric vehicles and energy storage systems. Cathode producers want lower-cost, reliable and scalable lithium inputs that can support high-volume manufacturing.

If lithium phosphate can meet strict cathode specifications, PLS could access a new customer base. Instead of selling only to lithium hydroxide or carbonate converters, it could sell directly into cathode material supply chains.

That would move PLS closer to battery manufacturers and allow it to capture more margin inside the lithium value chain.

Quality Testing Will Determine Commercial Potential

The opportunity remains at an early stage. PLS has warned that lithium phosphate must meet demanding quality requirements before it can become a commercial cathode feedstock.

Battery material customers require tight control over impurities, consistency, particle characteristics and chemical performance. A product that works technically at small scale must still prove reliability across repeated production.

Ronbay’s role is therefore important. As a major LFP cathode producer, it can provide practical feedback on product suitability, processing performance and downstream qualification needs.

The agreement also reflects a broader trend in lithium markets. Producers are no longer focused only on mining and concentrate production. They are looking for midstream products that can reduce processing complexity and improve customer access.

For PLS, lithium phosphate could serve multiple markets. It may supply existing lithium chemical producers, while also opening a direct route to cathode manufacturers.

The demonstration plant will test whether that strategy can move from concept to commercial scale. If successful, it could give spodumene producers a new pathway into battery materials without fully entering carbonate or hydroxide production.

The Metalnomist Commentary

PLS’ lithium phosphate strategy is a clear attempt to move higher in the battery value chain without jumping directly into full chemical conversion. The key test will be whether cathode makers accept lithium phosphate as a reliable feedstock at scale, not just as a technical possibility.
