ABSTRACT:
Electrochemical cell having at least two battery stacks each including an electrode assembly wound on a spool. Each electrode assembly includes two elongated electrode structures, an anode electrode structure and a cathode current collector structure. The electrode structures are wound around the center post of the spool with the anode electrode structure making contact with one of the conductive flanges of the spool and the cathode current collector structure making electrical contact with the other conductive flange of the spool. The flanges in contact with the anode structures of the battery stacks are connected to one external terminal of the cell, and the flanges in contact with the cathode current collector structures of the battery stacks are connected to another external terminal of the cell.
