ABSTRACT:
In order to avoid a distinct two step plateau in the discharge voltage of a divalent silver oxide cell, the positive depolarizing mixture pellet in the positive cap serving as the cathode terminal of the cell is covered with a silver or mono-silver oxide layer. The layer is, for example, formed of foamed silver which is partially compressed during assembly of the cell. Monovalent silver oxide powder may be applied to and penetrate in the foamed silver. Alternatively, the surface of the foamed silver may be oxidized to form a mono-silver oxide layer thereon.
