Abstract:
A positive electrode for an alkaline battery of the present invention includes a spinel-type manganese oxide as a positive electrode active material, wherein the spinel-type manganese oxide has a potential of 0.26 to 0.34 V with respect to a Hg/HgO reference electrode, and the content of the spinel-type manganese oxide in the entire positive electrode active material is not less than 30 mass %. Further, an alkaline battery of the present invention includes the above-described positive electrode for an alkaline battery of the invention, a negative electrode and an electrolyte.
