Envia Systems announcement may herald the first wave of DOE-supported commercial high energy density Li-ion cells with Si-C anodes

Green Car Congress

As an example, the military’s BB-2590 Li-ion battery used in a range of portable systems calls for a cycle life of ≥224 and ≥ 3 years.). LIB capacity is limited in part by the intercalation of Li ions by the anode material—i.e., Envia is targeting its high energy density Li-ion cells at plug-in hybrid and electric vehicles.
