1,221,716. Nickel-zinc cells. GULF GENERAL ATOMIC Inc. 20 Nov., 1968 [22 Nov., 1967], No. 55026/68. Heading H1B. In a nickel-zinc cell the electrolyte is circulated through the cell and the reaction products formed on discharge are separated from the electrolyte and stored outside the cell so that the zinc can be redeposited on the anode during recharging. As described, an alkaline battery has bipolar electrodes separated by electrolyte-frames. Each bipolar electrode consists of a mild steel sheet with zinc electroplated on one surface and a porous nickel sinter impregnated with nickel hydroxide welded to the opposite surface. A portion of the aq. KOH which is circulated is diverted from the cells through the separator/storage means where ZnO is removed, e.g. by a self-cleaning filter and stored during discharge or picked up during recharge. |
