High discharge rate electric cells and batteries
Abstract
Abstract High discharge rate electric cells in which an assembly of opposite polarity electrodes and separators in wound form are provided. The opposite polarity electrodes have bared conductive edge portions of their carriers which project respectively from opposite ends of the assembly. These respective projecting edge portions are slotted and folded down at the opposite ends substantially perpendicular to the surfaces of the electrodes. The projecting edge portions are of sufficient width so that when folded they extend over a distance greater than the distance between two adjacent spires of the same wound electrode. The adjacent segments of the conductive edge portions defined by the slots therein partially overlap laterally so as to form at the respective ends of the assembly a substantially plane elastically deformable surface for electrical contact with a current collector which latter may be welded at selected localities thereto, one of said collectors being the bottom of the metallic casing and the other being a metallic cover insulated from the casing and sealingly joined thereto.
