Amprius Technologies develops and manufactures lithium-ion batteries using proprietary silicon anode technology for electric aviation, vehicles, and other mobility applications. The company's silicon anodes store approximately 10 times the lithium capacity of conventional graphite anodes, enabling higher energy density, faster charging, and wider temperature operation; its commercial SiCore product line delivers up to 450 Wh/kg energy density and serves as a drop-in replacement for existing graphite-based batteries, while its development-stage SiMaxx line targets even higher performance. Amprius generates revenue through battery cell sales and engineering services to customers across unmanned aerial systems, electric vertical takeoff and landing aircraft, and electric vehicles, working with tier-one manufacturers including Airbus, AeroVironment, and BAE Systems, and scales production through contract manufacturing partnerships with global manufacturers.
