Abstract
An alkaline storage battery includes: a positive electrode containing nickel hydroxide; a negative electrode; a separator layer intervening between the positive electrode and the negative electrode; and an alkaline electrolyte. The separator layer includes a water-absorbing polymer, a water repellent, an alkaline aqueous solution, and a scavenger capable of trapping an element which leaches from the negative electrode into the alkaline aqueous solution. The scavenger comprises an oxygen-containing metal compound. The negative electrode is a hydrogen storage alloy electrode, a cadmium electrode or a zinc electrode. The water-absorbing polymer comprises a cross-linked polymer having at least one kind of monomer unit selected from the group consisting of an acrylate unit and a methacrylate unit.
