Used primarily as an ionic liquid in electrochemical applications due to its high ionic conductivity and thermal stability. Commonly employed in lithium-ion batteries and supercapacitors as a component of the electrolyte, where it helps improve charge-discharge efficiency and device safety. Its low volatility and wide electrochemical window make it suitable for high-temperature operations. Also utilized as a solvent in organic synthesis, especially in reactions involving catalysts that benefit from a stable, polar environment. Shows promise in carbon dioxide capture systems due to its gas solubility properties.
