Used as an electrolyte component in advanced lithium-ion and sodium-ion batteries due to its high ionic conductivity and wide electrochemical stability window. Its low viscosity and good thermal stability make it suitable for high-performance energy storage systems, especially in solid-state or quasi-solid electrolytes. Often employed in research settings to improve battery safety and cycling efficiency by reducing flammability compared to conventional organic electrolytes. Also explored in supercapacitors for enhanced charge-discharge rates and operational temperature range.
