NICKEL-ZINC STORAGE CELL Russian patent published in 1998 - IPC

FIELD: chemical power supplies. SUBSTANCE: nominal capacitance of negative electrodes is in range of 0.9-1.2 of nominal capacitance of positive electrodes which are located in electrolyte tank and are separated by separator. Active medium of negative electrode contains 10-25 weight percents of metal zinc and up to 5 weight percents of lead oxide. In addition porous diaphragm which is made from metal foil is located between positive and negative electrodes. Upper edge of diaphragm extends over electrodes and can be activated with catalytic agent. EFFECT: increased service life and increased electric characteristics. 6 cl, 1 dwg
