High Energy Density And Specific Energy Silicon Anode-Based Batteries (Energy Storage Innovations USA 2017)

Amprius has successfully developed a pure silicon anode with a nanowire structure that has enabled lithium-ion batteries with energy density and specific energy performance that exceed current state of the art graphite cells by 20-50%, depending on cell size and form factor. The rooted nanowire structure has very good mechanical stability, electrical conductivity and connectivity, and allows material swelling within the structure, extending the cycle life to hundreds of cycles. Amprius products have shown that silicon anode based batteries can reach 1,000 Wh/L and 400 Wh/Kg while maintaining a cycle life compatible with aerospace, military and other high-end applications.

Jon Bornstein, President and COO of Amprius Technologies, is a data-driven leader of R&D, engineering, and operations with a record of success in organizations spanning pre-product start-ups to public companies. Previously he led technology development at Ampulse Corporation, an innovative public-private solar technology partnership. Before that at Neophotonics Corp., a leading designer and manufacturer of optical integrated circuits, Jon was responsible for R&D, operations, and manufacturing. He grew the company from a 25-person materials research startup to an industry leader, recognized for technical excellence, on-time delivery, and outstanding customer service. Jon began his career in the semiconductor industry and held management positions in Intel Corp., Cypress Semiconductor, and Philips. He received his M.S. in Materials Science and Engineering at Stanford University and a B.S. in Chemistry from Antioch College.

Amprius is a leading manufacturer and developer of high energy and high capacity lithium-ion batteries, with products that enable new and mission critical applications in aerospace and air mobility.

Amprius' silicon anode technology was originally developed at Stanford University and enables dramatic improvements in the energy density and specific energy of lithium-ion batteries.
