摘要：
Thermally stable, flexible polymer gel electrolytes with high ionic conductivity are prepared by mixing the ionic liquid 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide (C(4)mpyrTFSI), LiTFSI and poly(vinylidene difluoride-co-hexafluoropropylene (PVDF-HFP). FT-IR and Raman spectroscopy show that an amorphous film is obtained for high (60 %) C(4)mpyrTFSI contents. Thermogravimetric analysis (TGA) confirms that the polymer gels are stable below similar to 300 degrees C in both nitrogen and air environments. Ionic conductivity of 1.9x10(-3) S cm(-2) at room temperature is achieved for the 60 % ionic liquid loaded gel. Germanium (Ge) anodes maintain a coulombic efficiency above 95 % after 90 cycles in potential cycling tests with the 60 % C(4)mpyrTFSI polymer gel.
