Abstract
An isolated, multipoint connection for a coiled electrode electrochemical cell which includes a cathode assembly with a cathode current collector having at least two connector tabs spaced apart on an edge of the current collector and an anode assembly having at least two connector tabs spaced apart on the edge of the anode assembly. Three barriers of nonconductive material are established to isolate the various components; a first nonconductive barrier which isolates the connector tabs from the remainder of the winding; a second nonconductive barrier which isolates the feedthrough and feedthrough pin from the case and from the anode elements; and a third nonconductive barrier established to separate the connections to the cathode connector tabs from the anode elements and from the case.
