Abstract

PURPOSE:To increase the life of a nickel-cadmium storage battery by interposing a separator consisting of a nonwoven synthetic-fiber fabric and a strongly basic anion exchange membrane between a positive and a negative plate before rolling the thus formed body. CONSTITUTION:After a nonwoven fabric 1 consisting of synthetic fibers with diameter of 0.5 microns or less and an OH<-> type strongly basic anion exchange membrane 2 are cut to equal dimensions, these members are applied to each other to make a separator 3. The separator 3 is then interposed between a positive and a negative plate 4 and 5 before the thus formed body is rolled to make an electrode group. A nickel-cadmium storage battery is constituted by using the thus made electrode group. In this nickel-cadmium storage battery, since positive ions dissolved into electrolyte during charge and discharge do not pass through an anion exchange membrane, they accumulate near the plate and do not diffuse into the counter electrode. Accordingly, even when the unit cell of the storage battery has a reverse charge, electrodeposition does not occur in the positive plate. Consequently, it is possible to increase the life performance of the storage battery.

ていた。Conventionally, in assembled batteries in which several 11 J of nickel-cadmium storage batteries are connected in series, variations in capacity occur between each storage battery as they are used, and at deep +i ([t'Jσ), storage batteries whose capacity has decreased are subject to reverse charging. This will happen. When this phenomenon occurs, cadmium is deposited in the gold of the cathode active material on the anode active material, thus forming a local battery that can self-discharge and, after one more charge/discharge operation, metal Cadmium's cylindrical crystal force occurs, causing short circuits, which slows down the deterioration of storage batteries with reduced capacity M, and shortens the lifespan of 811 batteries.

The resulting force is the current situation.
