Device for packaging a lithium battery
First Claim
1. Battery packing construction for packaging at least one lithium battery, said lithium battery including a solid polymer electrolyte in electrical contact with an anode of lithium or a lithium alloy and a cathode containing at least one metallic salt, said device comprisinga first metallic foil having a first continuous band of plastic film bonded thereto by means of a thermoset adhesive along entire peripheral edges of said first metallic foil,a second metallic foil having a second continuous band of plastic film bonded thereto by means of a thermoset adhesive along entire peripheral edges of said second metallic foil,said first and second metallic foils disposed over one another with the first and second plastic films arranged adjacent one another in facing relationship,said lithium battery being sandwiched between said first and said second metallic foils in space inside said first and said second continuous bands of plastic film with the anode in contact with one said metallic foil and the cathode in contact with the other metallic foil,said first and second continuous bands of plastic film being imperviously heat-sealed together to prevent any outside substance to contact said battery.

Abstract
Two metallic foils each have a continuous band of polyethylene film adhesively bonded thereto. The lithium battery is sandwiched between these two metallic foils and a thermo-seal is provided to join the two polyethylene films. This construction prevents any outside substance from contacting the lithium battery.
