L&F’s LFP Cathodes to Electrify U.S. Grid and EVs Without Chinese Minerals

Decarbonizing transportation and the grid hinges on scaling battery storage, yet reliance on Chinese-dominated LFP cathode production poses both strategic and environmental risks. This deal brings a new non-Chinese LFP sourcing channel online, potentially speeding up EV adoption and renewable integration while ensuring the supply chain aligns with U.S. climate and security policies—a crucial balancing act for the energy transition.

South Korean battery materials producer L&F has signed a mid- to long-term supply agreement with U.S.-based Coreshell Technologies to deliver lithium iron phosphate (LFP) cathode materials. The deal, announced on July 28, 2026, marks a strategic move to build a battery supply chain explicitly excluding Chinese-origin minerals and components, aligning with tightening U.S. national security and domestic sourcing requirements. L&F, a major player in cathode active materials, will expand its LFP business beyond energy storage systems (ESS) into electric mobility and defense applications through this partnership. Coreshell, a California-based battery technology firm, develops next-generation lithium-ion batteries using metallurgical silicon sourced domestically. The company has tested its products with global automakers and is now scaling into EVs, grid-scale storage, and defense.

China currently dominates the LFP cathode market, controlling over 90% of global production.

The partnership directly addresses legislative and regulatory pressures such as the National Defense Authorization Act (NDAA) and broader federal sourcing restrictions that increasingly demand batteries free of Chinese-controlled supply chains. L&F emphasized its non-Chinese cathode material network, asserting it can meet stringent U.S. requirements for strategic and defense-related industries. For Coreshell, access to L&F’s large-scale production capacity provides a compliant cathode source that supports domestic manufacturing and regulatory compliance across defense, EV, and grid energy storage customers.

The deal reflects a broader reconfiguration of global battery supply chains driven by geopolitical tensions and the U.S. Inflation Reduction Act’s push for localized, allied-nation sourcing. China currently dominates the LFP cathode market, controlling over 90% of global production. By targeting a China-free supply chain, L&F and Coreshell are betting on the willingness of U.S. automakers, defense contractors, and utilities to pay premiums for secure, compliant batteries. This mirrors moves by other Korean cathode producers like LG Chem and POSCO Future M to set up U.S. plants, but L&F’s approach of supplying directly to a U.S. technology firm for integrated battery manufacturing is distinct. It also highlights the growing importance of LFP chemistry in the U.S., which had been slower to adopt compared to China’s dominant LFP market.

For the defense sector, the implications are immediate: U.S. military platforms increasingly rely on advanced batteries for everything from unmanned systems to portable power. The NDAA’s country-of-origin restrictions mean many current battery inputs are non-compliant. This deal offers a concrete pathway to fielding batteries that meet those rules, though scaling production and validating the supply chain’s integrity will take years. For electric mobility, the agreement provides a potential cathode source for automakers seeking to qualify for IRA tax credits, which require a certain percentage of battery components to be sourced from the U.S. or free-trade agreement partners. Coreshell’s silicon-anode technology combined with L&F’s cathodes could yield high-energy-density LFP cells attractive for mid-range EVs.
