| 摘要 |
A method for the preparation of polymer electrolytes used in rechargeable lithium intercalation cells that contain a lithium salt capable of dissociation dispersed in a polymer matrix comprising a self-supporting vinylidene fluoride/hexafluoropropylene copolymer film, comprises exchanging plasticiser in the film with a solution of the lithium salt in an organic solvent so that the polymer contains 20-70 wt.% of the lithium salt solution. The plasticiser used is stable under electrochemical conditions in the cell and is chosen from hexylene carbonate, octylene carbonate or tributyl phosphate. |
