摘要：

We report an all-solid-state Li rechargeable battery based on a hybrid membrane comprising a highly-concentrated poly(ethylene carbonate) (PEC) electrolyte with 80 wt.% of lithium bis(fluorosulfonyl) imide (LiFSI) and a three-dimensionally ordered macroporous polyimide matrix operating at room temperature. The PEC-LiFSI 80 wt.% electrolyte showed an ionic conductivity of the order of 10(-5) S cm(-1) at 30 degrees C and a quite high Li transference number, and was employed as a good ion-conductive solid polymer membrane for all-solid-state Li battery. To assure the mechanical stability, the polyimide matrix was combined as a porous substrate to support the electrolyte. A Li vertical bar PEC-LiFSI vertical bar LiFePO4 cell with the hybrid membrane delivered a reversible charge-discharge capacity close to 120 similar to 130 mAh g(-1) at 30 degrees C and C/20 rate.
