Ionic liquids, 1-ethyl-3-methylimidazolium hexafluorotantalate (EMITaF 6 ) and hexafluoroniobate (EMINbF 6 ) were synthesized by a new method. They showed lower melting points and higher decomposition temperatures than popular EMIBF 4 due to larger anion size. Electrolytic conductivities of these ionic liquids were about 6 mS cm - 1 at 25°C. Lowering the melting point of ionic liquids did not result in the improvement of low-temperature characteristics of carbon double-layer capacitors, however, the new ionic liquids showed long life compared with EMICF 3 SO 3 , EMI(CF 3 SO 2 ) 2 N, and EMI(C 2 F 5 SO 2 ) 2 N at 3.0 V, 70°C. The derivatives of the new ionic liquids having a methyl group in 2-position (l-ethyl-2,3-dimethylimidazolium salts) were not ionic liquids at room temperature.
