  • MANUFACTURING METHOD FOR LiCoO2, SINTERED BODY AND SPUTTERING TARGET
    Publication number: 20120305392
    Abstract: Provided is a method for stably manufacturing high-density sintered LiCoO2. Said method uses a CIP-and-sintering method, which has a forming step using cold hydrostatic pressing and a sintering step. The pressing force is at least 1000 kg/cm2, the sintering temperature is between 1050° C. and 1120° C., and the sintering time is at least two hours. This makes it possible to stably manufacture sintered LiCoO2 with a relative density of at least 90%, a resistivity of at most 3 k?·cm, and a mean grain diameter between 20 and 50 ?m.
