Title:
LITHIUM-COBALT OXIDE AND ITS PREPARATION METHOD
Document Type and Number:
Japanese Patent JP2009091192
Kind Code:
A
Abstract:
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.
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.
