Founded in 2008, Amprius is a manufacturer and developer of high energy density lithium-ion batteries.

The technology is centered on using silicon to replace carbon in lithium-ion battery electrodes and seeks to capture silicon’s greater lithium ion capacity potential. Using anodes with this technology could potentially create lithium-ion batteries that have a up to 80% improvement in battery life over existing high-end batteries.

Company’s short-term focus is on consumer electronics with a long-term interest in electric transportation. As of 2015 Amprius built about 1,000,000 batteries for testing with customers that include Nokia and some of U.S. and China-based manufacturers.

Introduced in May 2013, first-generation nanostructured battery products in market are able to store 580 watt-hours per liter: 20% to 30% higher than any other battery in the marketplace. Second-generation battery products will have approximately 700 Wh/L performances (17% improvement). Third-generation model would provide upwards of 750 Wh/L (32% improvement). The long-term product potential could reach 1000 Wh/L.

Dr. Steven Chu, Nobel Prize in Physics (2007), 12th United States Secretary of Energy (2009 to 2013) is on the Board of Directors.
