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 dye-sensitized solar cells and fuel cells, enhancing ion conductivity and device efficiency. Also investigated in separation processes, including extraction of metals and desulfurization of fuels, thanks to its tunable solubility and chemical robustness. Its non-volatile nature makes it suitable for use in green chemistry applications where reduced environmental impact is desired.
