ABSTRACT:
Disclosed is an alkaline storage battery which exhibit exceptional charge/discharge and cycle life characteristics by improved current collection and active material retention of the electrode substrate. The electrode comprises a substrate composed of a conductive core material and fibrous nickel members unitary sintered on both surfaces of the conductive core material, and a layer of an active material filled into the substrate. The fibrous nickel members of the substrate are bent or curved at least at their tip ends inside the active material layer to retain the active material.
