General description

1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide is a class of electrolytic materials that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.

Application

Ionic liquids (ILs) are molten salts with melting points lower than 100 °C. They usually consist of pair of organic cation and anion. ILs exhibit unique properties such as non-volatility, high thermal stability, and high ionic conductivity and find applications as electrolytes in lithium/sodium ion batteries and dye-sensitized solar cells. They are also used as media for synthesis of conducting polymers and intercalation electrode materials.
