Used as an ionic liquid in electrochemical applications such as batteries and capacitors due to its high thermal stability and low volatility. It serves as a solvent or electrolyte component in lithium-ion and lithium-sulfur battery systems, enhancing ion conductivity and improving electrode performance. Also applied in separation processes and catalysis where a non-aqueous, polar medium is required. Its hydrophobic nature and chemical inertness make it suitable for use in fuel cells and dye-sensitized solar cells. Additionally, it is employed in analytical chemistry as a background electrolyte in capillary electrophoresis.
