| Abstract: | 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 (SET3]TFSI]) were studied. SET3]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. |
