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. An electrode plate which is coated with active material has a designated area for tab attachment. The conductive tab area's active material is pierced with opposing, offset piercing plates which have raised surface probes which penetrate the conductive tab area's coating and substrate. This tab area is cleared of active material and reinforced with a reinforcing material and a conductive tab is welded to the thus treated area resulting in an electrode plate having a strong integrated tab assembly.

[ What is claimed is:] [1.]1. A method of producing an electrode plate having a conductive tab area comprising the steps of:(a) piercing an area of an electrode plate with opposing, offset piercing plates having raised surface probes;(b) clearing the resulting area to expose a porous substrate forming a conductive tab area;(c) reinforcing the exposed porous substrate; and(d) attaching a conductive tab to the reinforced porous substrate.
