Abstract: The disclosed technology relates to electrodes with a polyurethane based melt coating present in the electrode. When the electrode is used in an electrochemical cell, the polyurethane based melt coating acts as a separator in the cell. The disclosed technology includes integrated electrode assemblies that include (A) an electrode; and (B) a separator comprising an ionically conductive thermoplastic polyurethane composition; wherein the separator is melt coated onto the electrode. Also included are electro chemical cells made with these electrodes or integrated electrode assemblies, and processes of making the same.
