ELEKTRODESTRUKTUR TIL ELEKTROKEMISK ELEMENT

摘要

An electrode assembly adaptor to be wound on a spool to provide a battery stack for an electrochemical cell. The spool has a central post of insulating material and two conductive flanges. The electrode assembly includes two elongated electrode structures, an anode electrode structure and a cathode current collector electrode structure. Each electrode structure includes a metal substrate having deflective, resilient contact tabs spaced along one edge. An appropriate electrode material is adherent to the substrate. The electrode assembly of the two electrode structures with intervening insulating material is adapted to be wound around the post of the spool with the contact tabs of the anode electrode structure making contact with one of the flanges and with the contact tabs of the cathode current collector electrode structure making contact with the other flange.
