Amprius Technologies
"Lighter. Longer. Stronger."
Manufacturer of silicon anode lithium-ion battery cells delivering up to 500 Wh/kg energy density for drones, eVTOL and aviation.
Amprius Technologies, Inc. (NYSE: AMPX) is a U.S. manufacturer of high-energy-density lithium-ion battery cells built on a proprietary 100% silicon anode platform, the highest-capacity anode material available commercially. Its SiCore and SiMaxx product lines deliver energy densities up to roughly 450-500 Wh/kg and 1,150 Wh/L, substantially exceeding conventional graphite-anode cells, while supporting fast charging (to 80% in as little as six minutes), high discharge rates, and a wide operating temperature range from -30 degrees C.
These attributes make the cells well suited to weight- and runtime-sensitive applications including unmanned aircraft systems (UAS), high-altitude pseudo-satellites, electric vertical takeoff and landing (eVTOL) aircraft, manned aviation, light electric vehicles, wearables, and emerging AI and robotics platforms such as humanoid robots. Amprius operates a MWh-scale manufacturing facility in Fremont, California, and has secured GWh-scale contract-manufacturing partnerships in Asia to scale capacity. Customers and partners cited by the company include Nokia Drone Networks, AALTO (Airbus), and BAE Systems subsidiary Prismatic, whose PHASA-35 stratospheric platform uses Amprius cells. The company has reported repeat purchase orders exceeding $35 million from a leading UAS manufacturer.
Founded in 2008 and headquartered in Fremont, Amprius commercializes technology originating from research at Stanford University. The company holds ISO 9001:2015 and AS9100:2016 quality certifications relevant to aerospace supply. Amprius positions silicon anode chemistry as an enabling component for next-generation electric mobility across air, land, and sea where payload, range, and reliability are critical.
