Compared with two years ago, the U.S. lithium-ion battery industry has changed a lot. After the federal EV tax credit ended in September 2025, several cell plants slowed EV output and shifted lines to LFP cells for energy storage, while defense and industrial buyers began asking harder questions about where their cells come from.<\/p>\n\n\n\n

This guide lists 12 lithium-ion battery manufacturers in the USA, split into two groups that buyers often confuse: battery cell manufacturers (the gigafactories that make the cells themselves) and battery pack and system manufacturers (the companies that design and assemble finished battery packs for OEMs). Knowing which group you need saves weeks of emailing the wrong suppliers.<\/p>\n\n\n\n

U.S. Lithium-Ion Battery Cell Manufacturers<\/h2>\n\n\n\n

These companies produce cells at gigawatt-hour scale. They mostly sell to automakers and large energy storage integrators under long-term contracts, so a typical OEM ordering a few thousand battery packs a year will not buy cells from them directly. They matter for understanding where U.S. supply is heading.<\/p>\n\n\n\n
