Patent ID: 11637283

Abstract:
Provided is a positive electrode active material for non-aqueous electrolyte secondary batteries for making high capacity and high output compatible, non-aqueous electrolyte secondary batteries, to which the positive electrode active material is adopted, and a production method for a positive electrode active material in which the positive electrode active material can be easily produced even on an industrial scale. A positive electrode active material for non-aqueous electrolyte secondary batteries, comprising: primary particles of a lithium nickel composite oxide represented by at least General Formula: LizNi1-x-yCoxMyO2 (0.95≤z≤1.03, 0<x≤0.20, 0<y≤0.10, x+y≤0.20, and M is at least one type of element selected from Mg, Al, Ca, Ti, V, Cr, Mn, Nb, Zr, and Mo); and secondary particles configured by aggregating the primary particles, wherein an LiAl compound is provided on surfaces of the primary particles.
