Amprius Technologies, Inc. engages in the manufacture and distribution of batteries. The company is headquartered in Westbury, New York and currently employs 58 full-time employees. The company went IPO on 2022-03-02. The firm is engaged in commercial production of an ultra-high energy density lithium-ion battery for mobility applications leveraging disruptive silicon anodes. Its silicon anode technology enables batteries with higher energy density, higher power density, and fast charging capabilities over a range of operating temperatures. The firm's silicon anodes are a direct drop-in replacement of the graphite anode in traditional lithium-ion batteries, and its manufacturing process leverages the manufacturing process for conventional lithium-ion batteries and the related supply chain. Its batteries are primarily used for existing and emerging aviation applications, including unmanned aerial systems (UAS), such as drones and high-altitude pseudo satellites (HAPS). Its technology has the potential for application in electric transportation.
