ABSTRACT:
A lithium-iodine cell comprising a region of iodine-containing cathode material having at least two surface portions, a current collector element operatively contacting one of the surface portions and a lithium anode element operatively contacting the other cathode surface. The lithium anode element is embraced by a holder in a manner exposing a surface of the element to the cathode material and sealing the corresponding anode current collector element from exposure to the cathode material, the holder being of a material which does not exhibit electronic conduction when exposed to iodine. The anode and cathode current collectors have extending lead portions, and the cathode lead is insulated from the lithium anode element. A pair of cells are combined, being heat sealed together around the peripheries, with the corresponding cathode regions contacting opposite surfaces of a separator sheet to form a battery.
