Classification: CPC H  Y | IPC H

Claim 19:
20. An electrochemical system, comprising:
an electrode structure, comprising:
a first release layer, comprising one or more of the following materials: polyimide with a hexafluoropropylene coating; siliconized polyester films, metallized polyester films, polybenzimidazoles, polybenzoxazoles, ethylene-acrylic acid copolymers, acrylate based polymers, polyvinylpyrrolidone-polyvinylimidazole copolymers, polyacrylonitriles, styrene-acrylonitriles, thermoplastic polyurethane polymers, polysulfone-polyalkylene oxide copolymers, benzophenone-modified polysulfone polymers, polyvinylpyrrolidone-polyvinylactetate copolymers, and combinations thereof;
a first protective layer disposed on the first release layer; and
a first electroactive material layer disposed on the first protective layer; and

an electrolyte, wherein the first release layer is a polymeric release layer, wherein the first release layer is soluble in the electrolyte, wherein the electrochemical system is configured such that assembly thereof into an electrochemical cell causes the electrolyte to contact the first release layer, and wherein the contact between the electrolyte and the first release layer causes the release layer to be dissolved in the electrolyte and thereby removed from the electrode structure.
