Abstract

Provided is a cathode active material for a non-aqueous-electrolyte secondary battery, the cathode active material containing a lithium composite oxide that has a layered structure containing a Li layer and that is represented by general formula LiaNiαAlβCoγMδSrxO(in the formula, 0.95<a<1.05, 0.85≤α≤0.95, 0<β≤0.08, 0≤γ≤0.1, 0≤δ≤0.15, 0<x≤0.015, 0≤w<0.05, α+β+γ+δ=1, and M is at least one type of element selected from Mn, Fe, Ti, Si, Nb, Zr, Mo, and Zn), wherein the proportions of metal elements present in the Li layer excluding Li are in the range of 1-2.5 mol % with respect to the total molar quantity of metal elements in the lithium composite oxide excluding Li.
