  "textContent": "The present invention aims to provide a positive electrode active material for nonaqueous electrolyte secondary batteries which achieves high output and high capacity when used as a positive electrode material. Disclosed is a method for manufacturing the positive electrode active material for nonaqueous electrolyte secondary batteries, the method comprising: a first step, wherein an alkaline solution with a tungsten compound dissolved therein is added to and mixed with a lithium metal composite oxide powder represented by a general formula LiNiCoMO(wherein, 0.10≤x≤0.35, 0≤y≤0.35, 0.97≤Z≤1.20, and M is at least one element selected from Mn, V, Mg, Mo, Nb, Ti, and Al), including primary particles and secondary particles composed of aggregation of the primary particles, and thereby W is dispersed on a surface of the primary particles; and a second step, wherein, by heat treating the mixture of the alkaline solution with the tungsten compound dissolved therein and the lithium metal composite oxide powder, fine particles containing W and Li are formed on a surface of the primary particles.",
