Energy-dense, low-cost, silicon graphene anodes: tailored for both liquid and solid electrolyte batteries

Silicon anodes provide opportunities for energy-dense chemistries. The use of Si in anodes in commercial liquid electrolyte Li-ion batteries has been slowly but steadily rising in recent years and more interestingly, the same silicon anodes are emerging in solid-state batteries as well.

In this talk we unveil NanoXplore’s proprietary silicon graphene composite anode with excellent electron/ion transport, high reversible capacity, mechanical integrity, and stable cycle life performance. We will show how our patented mechanofusion technique tightly wraps graphene over the surface of Si particles, providing the stability and the conductivity that make such anode active materials a viable solution for large scale battery cell manufacturing, both for commercial Li-ion batteries and the emerging solid-state chemistries.
