(JP2000090933-A)   NOVELTY - A portion of the transition metal (Me) in a lithium transition metal compound of formula LiMexOy is substituted by not less than 2 elements (M) selected from Li, Fe, Mn, Mg, Zn, B, Al, Co, Cr, Si, Ti, Sn, P, V, Sb, Nb, Ta, Mo and W, to give the positive active material of formula LiMzMex-zOy, where M does not equal Me, providing the battery with small internal resistance and good charge-discharge cycle characteristics.    USE - Operational power source for portable electric equipment or motor driving battery for an electric vehicle or a hybrid electric vehicle.    ADVANTAGE - The battery has small internal resistance and good charge-discharge cycle characteristics.
