Silicon Anode Li-Ion Cell

Product Portfolio
Amprius Technologies, Inc. is a leading manufacturer of high-energy and high-power
lithium-ion batteries, producing the industry’s highest-known energy density cells. The
company’s commercially available SiMaxxTM batteries deliver up to 450 Wh/kg and 1,150
Wh/L, with third-party validation of 500Wh/kg and 1,300 Wh/L. Amprius expanded its
product portfolio to include the SiCoreTM platform in 2024, which delivers up to 400
Wh/kg, significantly enhancing its ability to serve additional customer applications.

The company’s corporate headquarters is in Fremont, California, where it maintains an

R&D lab and a MWh scale manufacturing facility for the fabrication of silicon anodes and
cells. To serve customer demand, Amprius entered into several agreements to secure
over 500MW/h of contract manufacturing available today and entered into a lease
agreement for a gigawatt-hour-scale facility in Brighton, Colorado.
