ABSTRACT:
A solid state electrochemical device comprising (i) an anode, (ii) a cathode, (iii) interposed between the anode and cathode, a polymeric electrolyte, and (iv) adjacent to either the anode or the cathode, on a side opposite to the polymeric electrolyte, a current collector comprising (a) an aluminum or copper foil and (b) on a side of the aluminum foil facing the cathode or the anode, a layer of a cured polymer, in an amount effective to prevent corrosion between the cathode or anode and the aluminum foil, which (1) is conductive, (2) is pin-hole free and (3) adheres to said aluminum foil. The layer of cured polymer provides corrosion resistance to the current collector.
