Abstract
There is provided a novel positive electrode active material for a secondary battery. A positive electrode active material for a secondary battery according to the present exemplary embodiment is represented by the following formula (I):Li(NiCrMnM1)O(I) wherein 0<x, 0<y, 0<z, x+y+z<2, and 0≦a≦2; and M1 contains at least one selected from the group consisting of Na and Mg. A positive electrode for a secondary battery according to the present exemplary embodiment has the positive electrode active material for a secondary battery according to the present exemplary embodiment. A method for manufacturing a secondary battery according to the present exemplary embodiment includes the steps of applying the positive electrode active material for a secondary battery according to the present exemplary embodiment on a positive electrode current collector to thereby fabricate a positive electrode for a secondary battery; and assembling the secondary battery by using the positive electrode for a secondary battery.
