Abstract
A film of organic electron donor material is formed to a predetermined thickness and shape and then the preformed film and a lithium element are pressed together in a manner bonding the film to the surface of the lithium element to form a coated lithium anode. During the pressing operation, the surface of the lithium element can be shaped to include formations such as corrugations which serve to increase the surface area thereof, and the pressure bonded film is of substantially uniform thickness over these formations. The resulting coating also is substantially free of voids so as to be of substantially uniform solidity. An entire coated anode assembly is formed in one pressing operation, so that bare lithium is not subjected to prolonged atmospheric exposure which, in turn, reduces or substantially eliminates the possibility of nitride formation on the surface of the lithium element which is coated simultaneously while being pressed. The resulting anode is for use in a lithium-halogen cell wherein the cathode contains a charge transfer complex of an organic donor component and halogen, and the material of the film can be the same as the organic donor component material of the char…
