PROBLEM TO BE SOLVED: To manufacture an alkaline storage battery having a good utilization factor of positive electrode and good cyclic characteristic by forming the positive electrode from a hydroxide covered with a higher order alkali oxide heat treated by cobalt manufactured in one storage by a mixer/stirror. SOLUTION: Nickel hydroxide and cobalt hydroxide are mixed in a mixer/ stirror and heated, whereto an alkali solution is added, and the cobalt hydroxide is oxidated while it is melted under co-existence of oxygen. Particles of nickel hydroxide are formed with the surfaces covered by a higher order cobalt oxide, while coagulation of the particles is suppressed, and surface-modified nickel hydroxide is established covered with higher order oxidated cobalt having good electroconductivity. |
