Process for manufacturing nickel-cobalt composite represented by Ni1-x-yCoxMnyMz(OH)2 (where, 0.05≦x≦0.95, 0≦y≦0.55, 0≦z≦0.1, x+y+z<1, and M is at least one metal element selected from Al, Mg, and the like), includes: forming seed particle, while reaction solution having mixed solution containing metal compounds and ammonia solution containing ammonium ion supply source at discharge head of an impeller from 50-100 m2/s2, the concentration of nickel ions is maintained within range 0.1-5 ppm by mass, whereby seed particles are formed; and growing seed particle wherein solution is obtained by supplying mixed and ammonium solutions to reaction solution is agitated with a concentration of nickel ions being maintained within range 5-300 ppm by mass and higher than the concentration of nickel ions in seed particle formation, whereby seed particles are grown up. |
