Abstract

Lithium batteries utilizing a novel plastic crystal electrolyte prepared from LiTFSI and Succinonitrile (5 mol % doping) were investigated at 20 and -5°C by charge/discharge galvanostatic cycling, with Li4Ti 5O12 as anode and LiFePO4 or LiCoO2 as cathode materials. At 20°C, with only 5 mol % of LiTFSI, this solid electrolyte showed an improved capacity retention for LiFePO4 (72% remaining capacity after 99 cycles at 5°C) and for LiCoO2 (76% capacity retained after 99 cycles at C/12). In general, the total performance of the batteries outperformed those of their polymer gel-based counterparts, and matched those based on ionic liquids.
