چکیده انگلیسی
Two ionic liquids based on guanidinium cations and TFSA− anion were prepared, and their electrochemical stabilities were investigated. The cathodic limiting potentials of the two ILs were 0.7 V versus Li/Li+, and their electrochemical windows were 4.2 V. However, the lithium plating and striping on Ni electrode could been observed in the two IL electrolytes containing 0.3 mol kg−1 of LiTFSA without additive. And Li/LiCoO2 cells using the two IL electrolytes without additive showed good capacity and cycle property at the current rate of 0.2 C.
