摘要：

Poly(ethylene carbonate)-based polymer electrolytes with lithium salts (LiX; X = TFSI, ClO4, BF4 and PF6) were prepared, and their lithium transference numbers (t(+)) were measured to make comparison between different anion radius and salt concentrations. The LiTFSI electrolytes had the highest t(+) and Li-ion conductivities of all samples at 80 degrees C; these values increased with increasing salt concentration. According to the results of FT-IR measurements for all concentrated samples, the changes of band fraction, which divide at around 1720 cm(-1) for carbonyl groups interact, with Li+ (C=O-Li+), are strongly related to the mobility of Li+ ions.
