Packaging material for hermetically sealed batteries

A method of packaging a rectangular electrolytic battery, comprising the steps of forming a sleeve from a flat, rectangular sheet of a laminate material by overlapping and joining opposite edges of the sheet; inserting a rectangular battery into one end of the sleeve, the battery having two electronic contacting leads extending from one side thereof and the battery being positioned within the sleeve wherein a portion of the leads is within the sleeve and a portion of the leads is outside said sleeve; joining the ends of the sleeve to form a seal along each end thereof, hermetically sealing the interior of the sleeve, one end of the sleeve forming a seal about the leads and the other end of the sleeve sealed adjacent the battery.

Flexible packaging for polymer electrolytic cell and method of forming

A method of securing a metal lead of a polymer battery to a flexible circuit, comprising the steps of positioning a metal lead of a polymer electrolyte battery onto a connection pad of a circuit; clamping the metal lead and the connection pad between two weld fixtures of an ultrasonic welder; compressing the metal lead and connection pad between the two weld fixtures to establish a pressure of about 44.9 psi to about 30.8 psi; and vibrating the weld fixtures at a frequency of about 20 kHz for about 0.1 seconds to about 2.0 seconds.
