<P>PROBLEM TO BE SOLVED: To provide highly homogeneous lithium-cobalt oxide by a heat-treatment carried out at a relatively low temperature for a short time, and its preparation method. <P>SOLUTION: A lithium-cobalt oxide powder is prepared by thermally decomposing a lithium-cobalt organic acid salt comprising a trivalent cobalt ion using a preparation method of the lithium-cobalt oxide powder comprising: (1) a step of mixing lithium hydroxide with a cobalt organic acid salt dissolved in an oxidizing medium and; (2) a step of thermally decomposing a precipitated lithium-cobalt organic acid salt. <P>COPYRIGHT: (C)2009,JPO&INPIT |
