  • Metal oxide composite cathode material for high energy density batteries
    Patent number: 4391729
    Abstract: An electrochemical cell incorporating cathode materials comprising at least one metal oxide, at least one metal, or mixture of metals or metal oxides incorporated in the matrix of a host metal oxide. The cathode materials of this invention are constructed by the chemical addition, reaction, or otherwise intimate contact of various metal oxides and/or metal elements during thermal treatment in mixed states. The materials thereby produced contain metals and oxides of the groups IB, IIB, IIIB, IVB, VB, VIB, VIIB, and VIII, which includes the noble metals and/or their oxide compounds.The incorporation of the metal oxides, metals or mixtures thereof substantially increases the discharge capacity and the overall performance of the cathode materials.
    Type: Grant
    Filed: June 30, 1980
    Date of Patent: July 5, 1983
    Assignee: Wilson Greatbatch Ltd.
    Inventors: Charles C. Liang, M. Elizabeth Bolster, Robert M. Murphy
