Used as an ionic liquid in electrochemical applications such as lithium-ion batteries and supercapacitors due to its high thermal stability and wide electrochemical window. Its non-volatile nature and good ionic conductivity make it suitable as a solvent or electrolyte component in fuel cells and dye-sensitized solar cells. Also employed in separation processes, including extraction of metals and desulfurization of fuels, thanks to its ability to dissolve a wide range of organic and inorganic compounds. Additionally, it serves as a green solvent in catalytic reactions where high stability and low volatility are required.
