| 英文摘要 | three choline-based ionic liquids functionalized with trimethylsilyl, allyl, and cynoethyl groups are synthesized in an inexpensive route as safe electrolytes for high-voltage lithium-ion batteries. the thermal stabilities, viscosities, conductivities, and electrochemical windows of these ils are reported. hybrid electrolytes were formulated by doping with 0.6 m lipf6/0.4 m lithium oxalydifluoroborate (liodfb) as salts and dimethyl carbonate (dmc) as co-solvent. by using 0.6 m lipf6/0.4 m liodfb trimethylsilylated choline-based il (sn1il-tfsi)/dmc as electrolyte, licoo2/graphite full cell showed excellent cycling performance with a capacity of 152 mah g(-1) and 99% capacity retention over 90 cycles at a cut-off voltage of 4.4 v. the propagation rate of sn1il-tfsi)/dmc electrolyte is only one quarter of the commercial electrolyte (1 m lipf6 ec/dec/dmc, v/v/v = 1/1/1), suggesting a better safety feature.
