An object of the present invention is to provide a positive electrode material for a non-aqueous electrolyte secondary battery that can suppress gelation of a positive electrode mixture paste without reducing charge / discharge capacity and output characteristics when used as a positive electrode material of a battery. General formula LiaNi1-x-yzCoxMnyMzO2 (where 0.10 ≦ x0.35, 0 ≦ y ≦ 0.35, 0 ≦ z ≦ 0.05, 0.97 ≦ a ≦ 1.30, M is V, A mixture of a lithium metal composite oxide represented by at least one element selected from Fe, Cu, Mg, Mo, Nb, Ti, Zr, W, and Al) and an ammonium tungstate powder. 5 g of the material was mixed with 100 ml of pure water, stirred for 10 minutes, and then allowed to stand for 30 minutes. The measured supernatant liquid pH value at 25 ° C. was 11.2 to 11.8. Provide material material. |
