Lyten, a leader in lithium-sulfur battery technology, has announced a major breakthrough in U.S. battery manufacturing with the production of the nation’s first battery grade lithium-metal foil made entirely from domestically sourced lithium and alloys. The development marks a significant step toward establishing a resilient, tariff-free U.S. battery supply chain.
The company, which already uses a fully localized supply chain for its sulfur cathodes, is now extending this localization to its lithium-metal anodes. The milestone positions Lyten as a key player in efforts to reduce dependence on Chinese-dominated battery material processing, aligning with growing calls from U.S. policymakers and defense agencies for domestic sourcing of critical minerals.
Lyten’s lithium-sulfur battery technology replaces nickel, manganese, cobalt, and graphite with a sulfur cathode and lithium-metal anode — materials that are abundant and geographically widespread, including within the United States. This architecture enables the production of ultra-lightweight batteries for use in electric vehicles, energy storage, drones, satellites, defense applications, and micromobility devices.
