The present invention provides a positive electrode active material for a lithium ion battery with excellent battery characteristics can be provided. The positive electrode active material for a lithium ion battery is represented by the following composition formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒLi x Ni 1-y M y O 2+±
(in the formula, M represents at least one selected from Sc, Ti, V, Cr, Mn, Fe, Co, Cu, Zn, Ga, Ge, Al, Bi, Sn, Mg, Ca, B, and Zr, 0.9 ‰¤ x ‰¤ 1.2, 0 < y ‰¤ 0.7, and ± > 0.1). |
