【 摘 要 】
The ionic conductivities of two different electrolytes, namely lithium hexafluorophosphate (LiPF6) and lithium bis (trifluoromethylsulfonyl) imide (LiTFSI), in carbonate-based solvents have been investigated. The ionic conductivity of LiTFSI electrolyte is slightly larger than the LiPF6 electrolyte, namely 2.7 mS/cm vs. 2.4 mS/cm. The results of cyclic voltammetry and electrochemical impedance spectroscopy measurements show that LiTFSI electrolyte exhibit a better reversible redox reaction. Therefore, in this work, the full-cell battery using LiTFSI electrolyte exhibited higher specific capacity than the battery cell using LiPF6 electrolyte, namely 83.1 mAh/g and 101.5 mAh/g for the LiPF6 and LiTFSI electrolytes, respectively. Higher capacity in LiTFSI battery is thus related to better ionic conductivity and reversible redox reaction of LiTFSI electrolyte.【 预 览 】
