Abstract

Achieved is a nickel-cobalt-manganese composite hydroxide which is excellent in reactivity with a lithium compound, and able to achieve a positive electrode active material which has excellent thermal stability and battery characteristics. The nickel-cobalt-manganese composite hydroxide is intended to serve as a precursor for a positive electrode active material of a non-aqueous electrolyte secondary battery, and represented by a general formula: NiCoMnM(OH)(0<x≤⅓, 0<y≤⅓, 0≤z≤0.1, M represents one or more elements selected from Mg, Al, Ca, Ti, V, Cr, Zr, Nb, Mo, and W), and the nickel-cobalt-manganese composite hydroxide has a specific surface area of 3.0 to 11.0 m/g as measured by a BET method through nitrogen adsorption, and an average valence of 2.4 or more for Co and Mn as obtained by redox titration.
