More Information
Summary:Disclosed is a polymer electrolyte for use in an electrochemical device. Said polymer electrolyte comprises at least one polymer having ion-exchangeable functional groups. The polymer also comprises ionic liquid functional groups. The ion-exchangeable functional groups comprise a polymer-bound anionic group, such as a sulfonate, a carboxylate, and a phosphonate or any anionic surfactant group. Also disclosed is an electrical device that comprises said polymer electrolyte material. Such electrical device preferably consists of a fuel cell, an electrical battery, a super capacitor, an electrochromic window or a solar cell.
