Enovix has developed a 3D silicon lithium-ion battery, which is 5-years ahead of the broader industry, with 2x higher energy density, around 900Wh/liter.
Specifically, silicon has up to 10x higher energy density than graphite as an anode material, but it is prone to swelling 300-400% when charging/discharging, and Enovix’s silicon anode solution aims to overcome this issue.
The company went public via SPAC in February-2021, acquired by Rodgers Silicon Valley, with an implied post-deal valuation of $1.12bn.
