Method of connecting electric leads to battery tabs

摘要

A method of connecting a generally flat battery lead to at least one flat current collector of a polymer battery, comprising the steps of: bending a generally planar lead about at least one generally planar current collector tab to form a layered area, wherein at least one planar tab is disposed between planar portions of the lead with the lead wrapped around one edge of at least one tab; clamping the layered area between two weld fixtures of an ultrasonic welder; and vibrating the weld fixtures to ultrasonically weld together the battery lead and at least one current collector tab.
