General description

1-Ethyl-3-methylimidazolium hexafluorophosphate 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 that adhere to one of the four categories of Greener Alternatives. 1-Ethyl-3-Methylimidazolium Hexafluorophosphate is an enabling product that enhances solid-state batteries by improving ionic conductivity. This leads to safer batteries with longer life cycles and higher energy density. 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 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.
