10,626 RECHARGEABLE ALKALINE MnO2-ZINC CELL The rechargeable cell comprises a cathode formed from a compressed mixture of manganese dioxide particles, electrically conductive particles and a binder; an anode separated from the cathode and containing amalgamated metallic zinc particles on an electrically conductive carrier in an amount sufficient to provide a limited anode discharge capacity of about one-third of the cathode capacity; an aqueous alkaline electrolyte; and a charge reserve mass comprising an oxide or hydroxide of zinc in an amount sufficient to provide a charge reserve capacity for said cell equal to at least 50 percent of the anode discharge capacity. |
