摘要 A nickel composite hydroxide having a volume-average particle size of the secondary particles of 8.0 μm to 50.0 μm is obtained, by obtaining a nickel composite hydroxide slurry in a primary crystallization process by providing an aqueous solution having at least a nickel salt and a neutralizer into a reaction vessel while continuously stirring in a state of not containing a complex ion formation agent, and controlling the crystallization reaction so that the ratio of the volume-average particles size of secondary particles with respect to that of the secondary particles finally obtained is 0.2 to 0.6, and producing the nickel composite hydroxide in a secondary crystallization process by continuing the crystallization process while keeping the amount of the obtained slurry constant, continuously removing only the liquid component of the slurry, and performing control so that the slurry has a temperature of 70° C. to 90° C. and a pH value at a standard liquid temperature of 25° C. of 10.0 to 11.0.
