The current collector contains a metal element A as a main component thereof. The positive electrode composite layer contains a two-phase compound containing lithium as a positive electrode active material. The positive electrode composite layer also contains as an additive a compound having a metal element B, in a composition thereof, that has a higher ionization tendency than the metal element A.",
