Abstract
A cathode active material for a non-aqueous electrolyte secondary battery including primary particles of a lithium nickel complex oxide represented by a general formula: LiNiCoMO, and secondary particles in which the primary particles aggregate, wherein a plurality of coated lithium nickel complex oxide particles are formed by disposing a compound containing tungsten and lithium on surfaces of the secondary particles and surfaces of the primary particles positioned inside the secondary particles, and wherein a relative standard deviation of a ratio of a number of atoms of tungsten to a number of atoms of a metallic component other than lithium contained in the coated lithium nickel complex oxide particles is 0.4 or lower.
