Used as a lithium salt in electrolytes for high-voltage lithium-ion batteries and lithium metal batteries due to its excellent thermal stability, wide electrochemical window, and high chemical and electrical stability. Its fluorinated structure enhances ionic conductivity in both liquid and solid electrolytes, improves battery performance at elevated temperatures, and suppresses lithium dendrite formation to reduce risks of short circuits or explosions. Commonly applied in advanced energy storage systems, including electric vehicles and portable electronics, where stable cycling and safety are critical. Also investigated for use in solid-state batteries and supercapacitors owing to its ability to support high charge-discharge rates, long cycle life, and operation across a wide temperature range.
