发明名称 Polymer electrolyte, a battery cell comprising the electrolyte and method of producing the electrolyte
摘要 A polymer electrolyte comprising a polymer, a metal salt and possibly 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, wherein the hydrophobic grafts are selected from the group of fluorinated chains or alkyl chains having at least 8 carbon atoms A polymer battery cell comprising a cathode, an anode, and a polymer gel electrolyte comprising a metal salt, a polymer and possibly 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. A method of producing a polymer electrolyte, wherein an anhydrous salt is dissolved in at least one first anhydrous solvent or plasticizer forming a first solution and that an amphiphilic graft copolymer comprising a backbone carrying hydrophilic and hydrophobic grafts attached to different carbon atoms in the backbone is either 1) dissolved in the first solution forming a polymer gel electrolyte, or 2) dissolved in at least one second solvent or plasticizer forming a second solution which is mixed with the first solution, where after the solvent is slowly evaporated, forming a solid polymer electrolyte.
