Used as an ionic liquid in electrochemical applications due to its high ionic conductivity and thermal stability. Commonly employed as an electrolyte in lithium-ion batteries and supercapacitors. Its wide electrochemical window allows for stable performance at high voltages. Also serves as a solvent or catalyst support in organic synthesis, especially in reactions requiring non-volatile and polar media. Exhibits good solubility for gases and organic compounds, making it suitable for use in gas separation and catalysis processes.
