Abstract: The present invention relates to coiled electrode assemblies having conductive tabs, methods of attaching the conductive tabs to the coiled electrode, and electrochemical cells employing such assemblies. In the process of the invention, the conductive tab area of an electrode plate (1) coated with active material is pierced with opposing, offset piercing plates (2) having raised surface probes (3) which penetrate the conductive tab area. The resulting area is cleared of active material, and a conductive tab is welded to the thus treated area resulting in an electrode plate having a strong integrated tab assembly.
