1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide

Ionic liquids are liquid at or near room temperature, with a low vapor pressure and a liquid range wide (up to 300 ℃), is a non-volatile liquid, composed of freely moving anions and cations composition, has many advantages such as good electrical conductivity, thermal stability and solubility, is good choice of high temperature electrolyte for supercapacitors.

Due to the high cost of ionic liquids, we can use Emim-TFSI and propylene carbonate (PC) solvents are prepared into electrolytes with different concentrations and used in electric double layer capacitors, but pure ionic liquids are the best choice for high temperature applications of capacitors.

As a non-aqueous solvent, EMIM TFSI is superior to traditional aprotic polar organic solvents in the electrochemical research of electroactive materials. Under microwave conditions, zinc oxide nanoparticles can be synthesized as green solvents, and it shows good solubility in carbon dioxide. Suitable for solvent reactions requiring high carbon dioxide solubility.
