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.
