Used as an ionic liquid in electrochemical applications such as lithium-ion batteries and supercapacitors due to its high ionic conductivity and wide electrochemical stability window. Its low volatility and high thermal stability make it suitable for use in high-temperature processes and as a green solvent in organic synthesis. Commonly employed in fuel cells and dye-sensitized solar cells to enhance device efficiency and performance. Also utilized in separation processes, including CO₂ capture and extraction of metals, thanks to its tunable solvation properties.
