ABSTRACT:
A lithium-iodine cell comprising a casing of electrically conducting material, an anode including a lithium element within the casing, an electrical conductor operatively connected to the lithium element and extending out from the casing, and a cathode comprising iodine-containing material in operative contact with both the casing and the lithium element. The anode electrical conductor is completely sealed from the rest of the cell, and the casing serves as the cathode current collector. The anode operative surface is provided with a coating of an organic electron donor material. The anode conductor is enclosed within the combination of an insulator element within the casing, an isolator element between the insulator and the conductor, and a ferrule having one end within the insulator and the other end extending from the casing. During assembly, the cathode material is introduced in heated form and a filling element is employed which serves to keep the edge of the casing open end clean to facilitate subsequent welding of a lid to the casing.
