Electrically-conducting adhesion-promoters

Claim 1

An electrode/current collector composite comprising: a metal foil suitable for use as a current collector, a layer of a solid polymeric matrix, electrically-conducting, adhesion-promoter comprising formed on at least one surface of the metal foil which comprises from about 30 to 80 weight percent of a conductive material; from about 20 to about 70 weight percent of a polymer derived from a solid matrix forming monomer or partial polymer thereof; and an effective amount of acid functionalities so as to enhance the adherence of this layer of electrically-conducting adhesion-promoter to the surface of the metal foil; and a a composite electrode paste selected from the group consisting of a cathode paste and an anode paste wherein the cathode paste comprises from about 1 to about 20 weight percent of a conductive material, from about 35 to about 60 weight percent of a compatible cathodic material, from about 10 to about 50 weight percent of an electrolytic solvent and from about 5 to 30 weight percent of a cathode prepolymer all based on the total weight of the paste and further wherein the anode paste comprises from about 1 to about 20 weight percent of a conductive material, from about 35 to about 60 weight percent of a compatible anodic material, from about 10 to about 50 weight percent of an electrolytic solvent and from about 5 to about 30 weight percent of an anode prepolymers all based on the total weight of the paste wherein said adhesion-promotor is interposed between said metal foil and said composite electrode.
