Used as an ionic liquid in electrochemical applications due to its high thermal stability and low volatility. Commonly employed as an electrolyte component in lithium-ion batteries and supercapacitors, where it enhances ionic conductivity and improves safety by reducing flammability. 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-volatile, polar media are required. Shows promise in carbon dioxide capture and separation processes due to tunable solvation properties.
