Used as an electrolyte additive in lithium-ion batteries to enhance ionic conductivity and improve battery performance at high temperatures. It is also employed in electrochemical devices due to its high thermal stability and low volatility. Additionally, it serves as a solvent or co-solvent in various organic reactions, particularly those requiring a polar aprotic environment. Its ionic liquid properties make it suitable for applications in catalysis, separation processes, and as a medium for electrochemical synthesis.
