Why GruEnergy

Our co-founders spent years looking for a way to manufacture silicon anode material that delivered high performance and did not require exotic, high-cost processes and large amounts of capital.

Through persistence and scientific talent, they came up with a material with better performance characteristics than any silicon anode material tested to date, and one that is economical to produce.

Our breakthroughs are paving the way for the next generation of battery cell design – large diameter cylindrical cells – which depend on silicon anode material to achieve their full potential in energy density and fast charge.
