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 electrolytes, where it enhances safety by reducing flammability compared to traditional organic solvents. Its wide electrochemical window allows stable performance at high voltages. Also utilized as a solvent or catalyst support in organic synthesis, especially in reactions requiring polar, non-aqueous environments. Shows promise in carbon dioxide capture and separation technologies due to its tunable solvation properties.
