Widely used as an ionic liquid in electrochemical applications, particularly in batteries and supercapacitors, due to its high conductivity and stability. It serves as an electrolyte in dye-sensitized solar cells, enhancing efficiency and performance. In chemical synthesis, it acts as a solvent or catalyst for various organic reactions, including polymerization and catalysis. Its thermal stability makes it suitable for high-temperature processes. Additionally, it is employed in gas separation technologies, particularly for capturing carbon dioxide, due to its selective absorption properties. In materials science, it is used to modify surfaces and create advanced functional materials.
