PROBLEM TO BE SOLVED: To provide LiNiO2 in which Li/Ni element ratio is never slipped in thermal treatment by mixing prescribed Li compound and Ni compound together, then putting the mixture into a specified starting material housing vessel and thermally treating it. SOLUTION: An easily decomposing Li compound, preferably LiNiO3 and/or LiOH, and a Ni compound, preferably Ni(OH)2 , are mixed together, and the mixture is put in a Ni box which is a starting material housing vessel, and thermally heated preferably within a range of 600-750 deg.C. Namely, the Ni box is used as the starting material housing vessel, whereby the evaporation and penetration into the box of the Li component can be suppressed, and LiNiO2 in which the slippage of element ratio of Li/Ni is suppressed can be provided by a relatively low temperature thermal treatment. |
