1. An electrochemical system, comprising:
a first electrode structure comprising:
a first release layer comprising one or more of the following materials: polysulfones, polyethersulfone, polyphenylsulfone, polyethersulfone-polyalkylene oxide copolymers, polyphenylsulfone-polyalkyleneoxide copolymers, polyisobutylene, polyisobutylene succinic anhydride, polyisobutylene-polyalkyleneoxide copolymers, polyamide 6, polyvinylpyrrolidone, polyvinylpyrrolidone-polyvinylimidazole copolymers, polyvinylpyrrolidone-polyvinylactetate copolymers, maleinimide-vinylether copolymers, polyacrylamides, fluorinated polyacrylates, polyethylene-polyvinylalcohol copolymers, polyethylene-polyvinylacetate copolymers, polyvinylalcohol and polyvinylacetate copolymers, polyoxymethylene, polyvinylbutyral, polyureas, polymers based on photodepolymerization of acrolein derivatives (CH2═CR—C(O)R), polysulfone-polyalkylene oxide copolymers, polyvinylidene difluoride, 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.
