F. Attorney, Agent or FirmForeign Application Priority Data1973-12-28 JAAbstractDisclosed is a divalent silver oxide cell having amorphous carbon and a current collector in the positive active material. Amorphous carbon is useful for quickly dropping the high voltage of the AgO which appears at the initiation of discharge to a lower constant voltage level. The current collector which is disposed in the positive active material reduces the internal resistance of the cell when operating at low ambient temperatures including room temperature. |
