摘要： The positive electrode active material in accordance with the present invention is used for a positive electrode for a lithium-ion secondary battery, includes Li, Mn, Ni, Co, and O atoms, and has a substantially halite type crystal structure. Specifically, it is preferably expressed by LiaMnbNicCodOe, where a is 0.85 to 1.1, b is 0.2 to 0.6, c is 0.2 to 0.6, d is 0.1 to 0.5, and e is 1 to 2 (the sum of b, c, and d being 1). Because of such composition and crystal structure, the positive electrode active material of the present invention reduces the amount of elution of the battery into the liquid electrolyte and enhances the stability at a high temperature.
