  • Reinforced coiled electrode assemblies and methods of producing same
    Patent number: 6298530
    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. 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.
    Type: Grant
