Abstract

In a battery cell electrical connection between electrodes (1, 3) and electrically conducting end members (6, 7) of the cell container (5 - 7) is accomplished in that a battery coil (4A) consisting of wound electrodes and separators (2), wherein the electrodes have axially protruding, electrically conducting net edges (1', 3'), is placed in the cell container with the net edges in contact with the end members and in that welding joints are externally accomplished between the net edges and the end members.
