Used as an ionic liquid in electrochemical applications, particularly in dye-sensitized solar cells (DSSCs) to enhance efficiency and stability. It serves as an electrolyte component, improving ion conductivity and charge transfer. Also employed in catalysis and organic synthesis as a solvent or reaction medium due to its unique properties, such as low volatility and thermal stability. Additionally, it finds use in energy storage systems, including batteries and supercapacitors, for its ability to facilitate ion transport and improve performance.
