ABSTRACT:
An electrode plate is formed from a porous electrode framework with welded-on current discharge lug for use in electrochemical storage cells. The electrode framework is formed from metallized plastic and has a current discharge lug welded on in a unilateral and overlapping manner on the weld-on edge of the electrode framework. The material thickness of the current discharge lug decreases in the weld-on end towards the weld-on edge. The material of the electrode framework assigned to the weld-on end of the current discharge lug is compressed in the region of the overlap. For greater stability of the welding, the weld-on end of the current discharge lug is formed by teeth spaced apart from one another by teeth interspaces. The teeth interspaces are at least wide enough that, when there is pressing during the welding on of the current discharge lug, the material of the electrode framework can swell between the teeth.
