Abstract:
The present invention industrially provides: a non-aqueous electrolyte secondary battery having a high energy density and high cycling characteristics; a cathode active material for a non-aqueous electrolyte secondary battery having a high packing efficiency; and a nickel manganese containing composite hydroxide having a small particle size, a narrow particle size distribution, and a high sphericity. When producing the nickel manganese containing composite hydroxide by a crystallization reaction using material solution where metal compounds including nickel and manganese dissolve, a nucleation process is performed in a non-oxidizing atmosphere by stirring an aqueous solution for nucleation, that includes the quantity of the material solution corresponding to 0.6% to 5.0% of the whole amount of substance of metal element included in a metal compound used for the overall crystallization reaction.

Claim (Index 1):
A nickel manganese containing composite hydroxide represented by a general formula of: Ni x Mn y M z (OH) 2  (x+y+z=1, 0.1\u2264x\u22640.7, 0.1\u2264y\u22640.5, 0.1\u2264z\u22640.5; M is one or more of element that is selected from among Co, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, and W),\n the nickel manganese containing composite hydroxide comprising secondary particles formed by an aggregation of primary particles, and the secondary particles having a median diameter D50 within a range of 1 \u03bcm to 6 \u03bcm, an index [(D90\u2212D10)/D50] which indicates a spread of a particle size distribution of less than 0.50, and a tap density according to JIS2512:2012 within a range of 1.60 g/cm 3  to (0.04\u00d7D50+1.60) g/cm 3 .
