Abstract
Lithium ion battery anodes including graphenic carbon particles are disclosed. Lithium ion batteries containing such anodes are also disclosed. The anodes include mixtures of lithium-reactive metal particles such as silicon, graphenic carbon particles, and a binder. The use of graphenic carbon particles in the anodes results in improved performance of the lithium ion batteries.
