Abstract
An alkaline storage battery such as a sealed nickel-cadmium storage battery has an improved current collector tab structure connected as a current path to the marginal edge of a spirally coiled electrode of an electrode assembly. The current collector tab structure comprises either a plurality of current collector tabs or a single current collector tab comprising a current collecting tab and a lead tab thicker than the current collecting tab. With this arrangement, the internal resistance of the storage battery is reduced, and high-rate discharge performance is achieved.
