NOVELTY - Cathode active material comprises metal compound and metal oxide compound. The metal compound and the metal oxide are in contact. USE - Cathode active material for use in battery (claimed). ADVANTAGE - The cathode evolves substantially no gaseous oxygen during operation of the battery, and can provide greater energy density, cost-effective, and exhibits greater electrochemical reversibility and resistance to oxygen generation during use. DETAILED DESCRIPTION - Cathode active material comprises metal compound and metal oxide compound. The metal compound having: MRx (I). The metal oxide compound having MyOz (II), The metal compound and the metal oxide are in contact. M=metal; x, y and z=positive nonzero real number; and R=atom, a molecule, or a radical, and has an oxidation state of -1. INDEPENDENT CLAIMS are included for: 1. a cathode material, which comprises: a cathode active material including a metal compound and a metal oxide, and an electrically-conductive material, such that one or both of the metal compound and the metal oxide are in contact with the electrically-conductive material; and 2. a battery, which comprises: a cathode (34), where the cathode includes a cathode active material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a battery. Cathode (34) Cathode material (36) Cathode current collector (38) Anode material (42) Electrolytic separator (46)
