Used as an ionic liquid in electrochemical applications such as lithium-ion batteries and supercapacitors due to its high thermal stability and good ionic conductivity. It helps improve electrolyte performance by enhancing conductivity and widening the electrochemical stability window. Also employed in dye-sensitized solar cells and as a solvent in organic synthesis where a non-volatile, polar medium is required. Its low volatility and high solvating ability make it suitable for use in green chemistry processes and in extraction techniques.
