Abstract
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.
Claims5
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 said at least one planar tab is disposed between planar portions of said lead with said lead wrapped around one edge of said at least one tab and with said lead disposed on opposite sides of said at least one tab;
- clamping said layered area between two weld fixtures of an ultrasonic welder;
- vibrating said weld fixtures to ultrasonically weld together said battery lead and said at least one current collector tab to form a multi-layered weld area comprised of said at least one tab and said planar portions of said lead;
- and
- trimming said weld area by removing said one edge of said at least one tab.
