ABSTRACT:
An ultra-thin button-type hermetically sealed battery containing two primary electrochemical cells of the lithium-carbon type. The battery includes two similar dish-shaped housing members having outwardly turned rims. The rims of the two housing members are welded to a thin flat collector member of the same diameter as the housing members to form a sealed enclosure of two chambers. Each chamber contains a carbon cathode, a lithium anode, insulating separators, and an appropriate electrolytic solution with the elements suitably arranged and mounted to provide two cells in series. Terminal members pass through the centers of the housing members and are insulated therefrom. One terminal member makes electrical contact to the cathode in one chamber and the other terminal member makes electrical contact to the anode in the other chamber. The battery has a diameter of approximately 25 millimeters and a thickness of about 3 millimeters.
