either case the exemplary cell 100 shown in fig3 includes a central electrode 120 comprising the current collector 10 of the present invention supporting at least one of the opposite polarity active materials for the sake of clarity the active materials are not shown supported on the current collector 10 however in a case negative cell configuration current collector 10 supports opposed layers of cathode active material contacting the opposite major sides thereof locked together through its many open areas the tab 18 is then connected to the terminal lead 116 such as by welding in a case positive cell configuration anode active material is locked together supported on the opposite major sides of the current collector the central electrode 120 of cell 100 is sealed in a separator envelope 122 to prevent direct contact with the opposite polarity electrode while not shown in fig3 in a case negative design the opposite polarity electrode is the anode comprised of anode active material contacted to the inner major sides of the current collector 12 shown in fig2 the wing portions 12 a and 12 b of collector 12 joined by the intermediate tab 18 a are folded downwardly toward each other with respect to tab 18 a and into electrical association with the opposed major sides of the intermediate cathode in a case positive cell configuration the opposed cathode plates are carried by the wing portions 12 a 12 b and folded.
