Abstract

A positive electrode material for an alkaline storage battery includes nickel hydroxide. Zn and an A element are held in solid solution in a crystallite of the nickel hydroxide, the A element being at least one element selected from the group consisting of Al, Ga, Mn, and Mo. The content of the A element, [A]/([Ni]+[A]+[Zn]), is 5 to 16% (where [A] represents the molarity of the A element,[Ni] represents the molarity of nickel, and [Zn] represents the molarity of zinc in the crystallite). [Zn]/([Ni]+[A]+[Zn]) is 1 to 10%. The nickel hydroxide includes α-phase nickel hydroxide and β-phase nickel hydroxide.
