ABSTRACT:
In an alkali metal/halogen or oxyhalide electrochemical cell wherein an alkali metal anode, preferably lithium, has a surface in operative contact with a halogen-containing or oxyhalide cathode/electrolyte including a solvent if necessary, a coating on the anode surface comprising a thin film or substrate material impregnated with organic material, for example organic electron donor material, or other suitable coating material. The substrate material is flexible, preferably a synthetic open mesh fabric material, and the film is prepared by contacting the substrate material with a solution of the organic material and solvent followed by drying. The resulting film is flexible and is applied to the operative surface of the anode thereby coating the same, preferably adhered to the surface by pressing. The flexible film can be applied equally well to anode surfaces which are either smooth and flat or irregular.
