U.S. battery startups hit a rough patch when the One Big Beautiful Bill eliminated battery and EV incentives, undercutting a chunk of future demand. But recently, they’ve found a lifeline in the defense world, helping to power everything from drones and torpedoes to infantry radios and fighter jets.
The Trump administration, despite its open disdain for EVs, acknowledges that batteries are an inescapable part of modern life. And like many things in Washington these days, it’s leaning on national security as justification for its recent decisions.
The latest comes from the Department of Energy, which announced Thursday that it is awarding $500 million in grants to bolster the battery supply chain in the United States. The program aims to “reduce reliance on foreign sources, bolster national security, and advance American energy dominance.” Much of the money went to startups.
Defense applications of lithium-ion batteries are “absolutely playing out in discussions,” a spokesperson for Coreshell, a battery materials startup, told TechCrunch. The company recently brought on ADS Ventures as an investor; the strategic VC’s parent company, ADS, is a defense supplier, and it’s working with another supplier of autonomous systems. Coreshell received a $50 million award from the DOE to expand manufacturing for its metallurgical silicon anode material.
