Rechargeable alkaline MnO/sub 2/--zinc cell. [reserve Zn mass not part of electrode for extra capacity]
Patent
·
OSTI ID:6610734
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 the cell equal to at least 50 percent of the anode discharge capacity. 6 figures.
