U.S. battery startups are entering a new phase as defense demand opens fresh opportunities for domestic manufacturing. After recent policy changes reduced support for electric vehicle incentives, several companies have found stronger momentum in military and security applications.
The U.S. Department of Energy has announced $500 million in grants to strengthen the country's battery supply chain, with a strong share of the funding directed to startups. The initiative is designed to reduce dependence on foreign materials, support energy resilience, and expand domestic production capacity.
Among the recipients, Coreshell secured $50 million to scale manufacturing of its metallurgical silicon anode material. The company says defense-related use cases are increasingly part of its growth strategy, alongside broader battery markets.
Lilac Solutions received $100 million to build a lithium processing facility in Utah near the Great Salt Lake, with plans to produce 5,000 metric tons of lithium carbonate a year by 2028. Nth Cycle also landed $100 million to develop a plant that will recover lithium and nickel compounds from recycled battery material, supporting a more circular supply chain.
Industry leaders note that defense is becoming a meaningful demand driver, especially for lightweight batteries used in drones, radios, torpedoes, and aircraft systems. At the same time, the automotive sector remains a major long-term market, keeping battery innovation on a broad growth path.
As domestic supply chains mature, battery technology is likely to connect defense, mobility, and clean industry in new ways, shaping a more resilient energy future.
