Full silicon nanowire anodes: towards highest energy density Lithium-ion batteries

The silicon nanowire anode technology addresses silicon swelling by enabling silicon to expand and contract internally, in a very robust mechanical structure. As a result, over 1200 Wh/L and 450 Wh/kg levels of energy density were achieved in lithium-ion cells with a cycle life in the hundreds of cycles and fast charging in under 10 minutes, enabling new devices and applications.
