Abstract

A prismatic storage battery. The battery has a housing, a coiled unit disposed in the housing and a cover disposed on the housing to seal and electronically connected to the coiled unit. The coiled unit is formed by a winded electrode sheet and a plurality of conductive plates and washers. As winding the electrode sheet, several coiled segments are formed, and one conductive plate and one washer in pairs are sequentially clamped by the flange of two adjacent coiled segments of the electrode sheet, i.e., the conductive plates are electronically connected to the electrode sheet through the flange of the electrode sheet. Thus, the coiled unit is conductive by two different paths through the conductive plates clamped by the coiled segments of the electrode sheet.
