Amprius Technologies, Inc. announced a manufacturing partnership with Nanotech Energy. This partnership secures a domestic production pathway for Amprius' high-performance silicon battery cells. Through its partnership with Nanotech Energy, Amprius establishes an American supply chain for its high-performance cells to support key customers, including L3Harris.
Nanotech Energy is Amprius' first U.S.-based manufacturing partner and strengthens the Company's ability to serve defense, aerospace, and other mission-critical markets by providing secure, domestic production that meets stringent sourcing and compliance requirements. The partnership aligns directly with the recently updated National Defense Authorization Act (NDAA) and enables Amprius to scale manufacturing of its silicon-anode cells while supporting national security programs that demand both superior performance and a trusted U.S. supply chain. The strategic value of this partnership is further validated by Amprius customers like L3Harris Technologies, which delivers end-to-end technology solutions connecting the space, air, land, sea, and cyber domains in the interest of national security.
Over the last several months, Amprius and Nanotech refined the design and manufacturing of the Amprius SA128 silicon-anode cell. Cell specifications include: Format: 21700 cylindrical; Capacity: 6.8 Ah; Energy density: 320 Wh/kg. The addition of U.S.-based contract manufacturing further strengthens Amprius' manufacturing-light model, extending its footprint across Asia and the United States, increasing global capacity beyond 2.0 GWh, and positioning the Company to support rising demand for its cells across commercial, industrial, and defense sectors.
