Used as an ionic liquid in electrochemical applications such as batteries and capacitors due to its high ionic conductivity and wide electrochemical window. It serves as a solvent or electrolyte component in fuel cells and dye-sensitized solar cells, enhancing device efficiency and stability. Also employed in catalysis and organic synthesis where its non-volatile and thermally stable properties improve reaction control. Commonly utilized in green chemistry processes as a reusable medium, reducing environmental impact. Its compatibility with polymer systems makes it suitable for use in conductive membranes and functional coatings.
