General description

1-Ethyl-3-methylimidazolium acetate 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.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

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 nonvolatility, high thermal stability and high ionic conductivity. They find applications as electrolytes in lithium/sodium ion batteries and dye-sensitized solar cells and also used as media for synthesis of conducting polymers and intercalation electrode materials.
