    Abstract: A direct welding process for joining a current collector to a terminal pin in the construction of electrochemical cells is described. The resistance welding process utilizes increased current combined with an applied force to bond dissimilar metals with a melting temperature differential of preferably more than 500° C. Preferably, the method is used to bond the terminal pin to the cathode current collector. This method of attachment is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.

    Abstract: A magnetic pulse welding process for joining a current collector to a terminal pin in the construction of electrochemical cells is described. The magnetic pulse welding process utilizes a pulsed direct current and an electrically conductive coil to generate an electro-magnetic force that causes two work pieces to collide with each other and form a bond therebetween. Preferably, the method is used to bond the terminal pin to the cathode current collector. This method of attachment is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.

    Abstract: A process for creating a laser braze weld joint between a current collector and a terminal pin in the construction of electrochemical cells is described. The laser braze welding process utilizes a laser weld instrument to create a braze-like joint between two work pieces. The weld joint is created by controlling the amount of laser heat and energy imparted to the work pieces through proper control and positioning of the laser beam with respect to the work pieces. Preferably, the method is used to bond the terminal pin to the cathode current collector. This method of attachment is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.

    Abstract: An electrochemical cell comprising an electrode assembly having a plurality of cathodes in which the plurality of cathodes is electrically connected together at a connection tab junction is disclosed. The junction preferably comprises a plurality of cathode connection tabs that are folded over each other to construct a junction that is mechanically and electrically robust. The junction is comprised of a plurality of connection tabs that each extend from a cathode. Each of the respective tabs is folded over each other to form a compact electrode junction having redundant connections. An elongated lead extends from the junction to provide an electrical connection to the plurality of cathodes. The junction is welded together such as by a laser, resistance or ultrasonic weld joint. The cathode junction is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.
