A closer look at graphite—its forms, functions and future in EV batteries

The term graphene gets thrown around quite a lot. Graphene is a single layer of carbon atoms. Graphite is a pure form of carbon—by the time we process it into anode material, it''s 99.95% pure—and it''s the most stable form of carbon. The graphene layer of each particle is pretty much the outside layer or two, and that''s where the ions
