Abstract

An alkaline secondary battery includes a positive electrode having active material particles principally made of nickel hydroxide, a negative electrode, and an electrolyte solution. The positive active material particle has a core layer containing nickel hydroxide and a conductive auxiliary layer which coats the surface of the core layer. The conductive auxiliary layer contains a cobalt oxyhydroxide phase and a cerium dioxide phase. The electrolyte solution is principally made of an aqueous sodium hydroxide solution.
