摘要：

This paper studied application of different types of room temperature ionic liquids (RTILs) into flexible supercapacitors. Typical RTILs including 1-buthyl-3-methyl-imidazolium [BMIM][Cl], trioctylmethylammonium bis(trifluoromethylsulfonyl)imide [OMA][TFSI] and triethylsulfonium bis(trifluoromethylsulfonyl)imide ([SET(3)][TFSI]) were studied. [SET(3)][TFSI] shows the best result as electrolyte in electrochemical double-layer (EDLC) supercapacitors; with very high specific capacitance of 244 F/g at room temperature. overceiling the performance of conventional carbonate electrolyte such as dimethyl carbonate (DMC) with more stable performance and much larger electrochemical window.
