ABSTRACT:
The invention relates to a method for preparing polymer electrolytes for rechargeable lithium intercalation cells which contain a dissociable lithium salt dispersed in a polymeric matrix, the polymeric matrix being a self-supporting film of a copolymer of vinylidene difluoride and hexafluoropropylene, in which the plasticizer is exchanged for a solution of the dissociable lithium salt, so that the polymeric electrolyte 20 to 70 wt % of the solution of the dissociable lithium salt, and is characterized in that a plasticizer is used which is stable under the electrochemical conditions of a rechargeable lithium intercalation cell and is selected from the group consisting of hexylene carbonate, octylene carbonate or tributyl phosphate.
