Abstract:
The purpose of the present invention is to easily provide at low cost, a cathode active material for non-aqueous electrolyte secondary batteries, which exhibits high particle strength and high weather resistance, while enabling achievement of excellent charge and discharge capacity and excellent output characteristics in cases where the cathode active material is used as a cathode material of a non-aqueous electrolyte secondary battery. A slurry of from 500 g/L to 2000 g/L is formed by adding water to a powder of a lithium nickel composite oxide represented by the general formula (A): Li z Ni 1-x-y Co x M y O 2 , where 0.10≤x≤0.20, 0≤y≤0.10, 0.97≤z≤1.20, and M represents at least one element selected from among Mn, V, Mg, Mo, Nb, Ti and Al); the slurry is washed with water by stirring; and after filtration, the resulting material is subjected to a heat treatment at a temperature of from 120° C. to 550° C. (inclusive) in an oxygen atmosphere having an oxygen concentration of 80% by volume or more.

Claim (Index 3):
The manufacturing method for manufacturing a cathode active material for a non-aqueous electrolyte secondary battery according to  claim 1 , wherein the temperature during the heat treatment is 120\u00b0 C. or greater but less than 400\u00b0 C.
