Application

This ionic liquid is primarily employed as an advanced electrolyte in energy storage devices due to its wide electrochemical stability window (>4.5V vs. Li/Li⁺). Researchers utilize it in lithium battery systems to improve safety and performance at elevated temperatures. It also serves as a polar solvent for organic synthesis and catalysis, particularly in reactions requiring non-coordinating media. Electrochemists value its application in sensor development and electrodeposition processes where traditional solvents are inadequate.
