A battery is comprised of a rigid, plastic housing defining a generally rectangular interior cavity, and an essentially flat interior surface. A battery rechargeable electric cell has a flexible outer packaging, an electrically conductive thermoset adhesive film, and is contained within the cavity. The cell is generally rectangular in shape and has a flat outer surface and two leads extending through the housing. The cell has a normal configuration when experiencing normal operating conditions, and an abnormal configuration when experiencing abnormal operating conditions. A membrane switch is disposed between the flat interior surface of the housing and the flat outer surface of the cell. The switch has at least one lead extending through the housing. The switch has a first electrical condition when the cell has the normal configuration and a second electrical condition when the cell has the abnormal configuration. The membrane switch is selected to have a predetermined operating pressure related to the battery size and shape.

Safety device for lithium-ion-polymer battery

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.
