1. A method for making electrical contact to a foil electrode of an electrochemical cell comprising the steps of punching an array of apertures in a predetermined section of a rectangularly shaped conductive element;

  • forming at least one pair of opposed teeth from the material punched from each aperture such that the teeth project from the same side of the conductive element, are longer than the thickness of the foil electrode, and are directed toward each other;

    pressing the conductive element into the surface of the foil electrode such that the teeth pierce through the electrode; and

    bending the teeth toward each other until they are flush with the opposite surface of the electrode.
