    摘要: 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, an electrode covering, preferably applied on the anode surface comprising a non-fabric, continuous and solid film of substrate material having a uniform unit weight, is described. The substrate material is perforated to provide for ion flow therethrough and coated with organic electron donor material, or other suitable coating material. The film substrate material preferably comprises a mechanically perforated synthetic polyester film material, and the film is prepared by contacting with a solution of the organic material and solvent followed by drying. The resulting coated film is flexible and is applied to the operative surface of the electrode thereby covering the same, preferably adhered to the surface by pressing. The flexible film can be applied equally well to electrode surfaces which are either smooth and flat or irregular.
