Abstract
An ultrasonic welding process for joining a current collector to an anode or cathode material of electrochemical cells is described. The ultrasonic welding process utilizes an ultrasonic welding frequency which may be combined with an applied force to bond dissimilar metals comprising the electrode material and the current collector. Preferably, the method is used to bond the anode material to the anode current collector. This method of attachment is suitable for either primary or secondary cells, particularly those powering implantable biomedical devices.
