  • Patent number: 8257865
    Abstract: The positive electrode active material in accordance with the present invention is used for a positive electrode for a lithium-ion secondary battery, includes Li, Mn, Ni, Co, and O atoms, and has a substantially halite type crystal structure. Specifically, it is preferably expressed by LiaMnbNicCodOe, where a is 0.85 to 1.1, b is 0.2 to 0.6, c is 0.2 to 0.6, d is 0.1 to 0.5, and e is 1 to 2 (the sum of b, c, and d being 1). Because of such composition and crystal structure, the positive electrode active material of the present invention reduces the amount of elution of the battery into the liquid electrolyte and enhances the stability at a high temperature.

  • Patent number: 8084151
    Abstract: When an output voltage of a fuel cell is lowered to carry out a catalyst activation process so as to activate a catalyst during an intermittent operation of the fuel cell, if generated power P1 exceeds allowed battery charge power, while generated power P2 does not exceed the allowed battery charge power, then low speed corresponding to the generated power P2 is selected and the output voltage of the fuel cell is decreased toward a target voltage on the basis of the low speed, which has been selected, thereby restraining sudden generation of surplus power caused by a reduction in the output voltage of the fuel cell. By the control described above, a voltage reduction speed of a fuel cell is determined according to a receiving capability of an object which receives surplus power generated by the fuel cell during the catalyst activation process of the fuel cell.
