Used as a highly stable ionic liquid in electrochemical applications such as batteries and supercapacitors due to its wide electrochemical window and excellent thermal stability. Its low volatility and high ionic conductivity make it suitable as an electrolyte solvent in lithium-ion and other advanced battery systems. Also employed as a catalyst support or reaction medium in organic synthesis, especially in reactions requiring inert and polar environments. Additionally, it finds use in fuel cells and dye-sensitized solar cells for improving ion transport and device efficiency.
