ABSTRACT:
Apparatus and method for mechanically and electrically interconnecting the individual electrochemical cells for a battery. A cell-holding fixture maintains the cells in fixed relationship and includes a conductive electrode disposed adjacent each terminal to be interconnected. Projecting cell terminals are partially bent about the conductive electrodes by pivotal arms and the fixture is then moved toward the ends of the arms Zto complete the bending of the terminals so that they lie in a common plane. A conductive link is placed over the bent terminals and a pair of welding electrodes, one in contact with the conductive link and the other in electrical contact with the conductive electrode of the fixture, passes a welding current through the link and terminal to effect the weld. The fixture is passed over an adhesive strip applicator for taping together the bottom surfaces of the cells prior to their removal from the fixture.
