Disclosed is a positive electrode active material for a lithium ion battery which exhibits good battery performance. The positive electrode active material for lithium ion batteries is represented by the structural formula: Li(LixNi1-x-yMy)O2+a. (In the structural 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=x=0.1; 0<y=0.7; and a>0.) |
