In lithium-ion batteries, lithium-containing metal oxides are generally used as the cathode and graphite as the anode. Active materials are in the form of a powder, and binders are "glue" used to hold them together and fix them on a metal foil called a current collector foil (cathode: aluminum foil, anode: copper foil).
