実験手順

A nickel sulfate-cobalt sulfate mixed solution is prepared by dissolving nickel sulfate and cobalt sulfate at a molar ratio of Co to Ni of 20%. By adding a solution of sodium hydroxide to the nickel sulfate-cobalt sulfate mixed solution, a nickel-cobalt hydroxide is obtained by co-precipitation. By washing the obtained nickel-cobalt hydroxide in water and drying at 80° C., it becomes powdery and a nickel-cobalt hydroxide, Ni0.8Co0.2(OH)2, in which secondary particles similar to spherical or elliptic spherical particles in shape have been formed is obtained.
