Summary: | When producing a nickel composite hydroxide that is a precursor to the cathode active material for a non-aqueous electrolyte secondary battery by supplying an aqueous solution that includes at least a nickel salt, a neutralizing agent and a complexing agent into a reaction vessel while stirring and performing a crystallization reaction, a nickel composite hydroxide slurry is obtained while controlling the ratio of the average particle size per volume of secondary particles of nickel composite hydroxide that is generated inside the reaction vessel with respect to the average particle size per volume of secondary particles of nickel composite hydroxide that is finally obtained so as to be 0.2 to 0.6, after which, while keeping the amount of slurry constant and continuously removing only the liquid component, the crystallization reaction is continued until the average particle size per volume of secondary particles of the nickel composite hydroxide becomes 8.0 μm to 50.0 μm. |
