| Zusammenfassung: | An alkaline secondary battery having excellent charge-discharge cycle characteristics is provided. The alkaline secondary battery includes a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode. The positive electrode contains a silver oxide. The negative electrode contains zinc-based particles selected from the group consisting of zinc particles and zinc alloy particles. The separator holds an alkaline electrolyte solution. An anion conductive membrane is disposed between the negative electrode and the separator. The anion conductive membrane includes a polymer as a matrix and particles of at least one metal compound selected from the group consisting of metal oxides, metal hydroxides, metal carbonates, metal sulfates, metal phosphates, metal borates, and metal silicates, which are dispersed in the matrix. |
