Abstract

See full text

A positive electrode active material for a lithium ion secondary battery, includes lithium-nickel composite oxide particles and a coating layer that covers at least a part of surfaces of the lithium-nickel composite oxide particles, in which components other than oxygen of the lithium-nickel composite oxide are represented by Li:Ni:Co:M=t:1−x−y:x:y (where, M is at least one element selected from the group consisting of Mg, Al, Ca, Si, Ti, V, Fe, Cu, Cr, Zn, Zr, Nb, Mo, or W, 0.95≤t≤1.20, 02 surface area of the lithium-nickel composite oxide is 7.0 μmol or more and 60 μmol or less.
