Widely used as an ionic liquid in electrochemical applications, particularly in energy storage devices like batteries and supercapacitors. Its high thermal stability and low volatility make it suitable for use as an electrolyte in lithium-ion batteries, enhancing safety and performance. It is also employed in dye-sensitized solar cells to improve efficiency and longevity. In chemical synthesis, it serves as a green solvent for various reactions, including catalysis and polymerization, due to its non-flammability and recyclability. Additionally, it is utilized in gas separation processes and as a lubricant additive to reduce friction and wear in mechanical systems.
