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.
