Used primarily as an ionic liquid in electrochemical applications due to its high ionic conductivity and thermal stability. Commonly employed in lithium-ion batteries and supercapacitors as a component of the electrolyte, where it enhances safety by reducing flammability compared to conventional organic solvents. Its wide electrochemical window allows stable performance at high voltages. Also utilized in dye-sensitized solar cells and as a solvent in organic synthesis where non-volatility and reusability are advantageous. Suitable for use in high-temperature processes owing to its low vapor pressure and robust decomposition resistance.
