摘要： The present invention aims to provide an alkaline secondary battery having a large discharge capacity, and little performance degradation during overdischarge. The object of the present invention can be achieved by a positive active material for an alkaline secondary battery having a core layer containing nickel hydroxide and a conductive auxiliary layer which coats the surface of the core layer, wherein the conductive auxiliary layer contains a cobalt oxyhydroxide phase and a cerium dioxide phase, and the active material contains lithium. The inclusion of the cerium dioxide phase in the conductive auxiliary layer enables the inhibition of reduction of cobalt oxyhydroxide even in conditions such as overdischarge. The inclusion of lithium in the active material and the inclusion of the cerium dioxide phase in the conductive auxiliary layer enable the increase of the battery discharge capacity.
