A rechargeable cell has an anode, a cathode, barrier means between the cathode and anode, and an electrolyte in contact with the elements of the cell, the cathode being formed from a mixture of monovalent silver oxide and finely divided silver, nickel, or a mixture of silver and nickel. The cathode may also contain a second active material, e.g. HgO, to provide a discharge voltage which drops in a step before the cell is fully discharged, to indicate that recharging is needed. The added silver and/or nickel enhances rechargeability. |
