Polymer electrolyte, a battery cell comprising the electrolyte and method of producing the electrolyte

摘要

The invention relates to a polymer electrolyte comprising a polymer, a metal salt and at least one plasticizer or solvent, wherein the polymer is an amphiphilic graft copolymer comprising a backbone carrying hydrophilic and hydrophobic grafts attached to different carbon atoms in the backbone, and further wherein the hydrophobic grafts are selected from the group of fluorinated chains or alkyl chains having at least 8 carbon atoms. The invention also relates to a battery cell comprising a polymer electrolyte and methods of producing a polymer electrolyte.
