Used as an electrolyte additive in lithium-ion batteries to improve cycle life and thermal stability. Enhances the formation of a stable solid electrolyte interphase (SEI) layer on the anode, which reduces electrolyte decomposition and increases battery safety. Also improves low-temperature performance and charge-discharge efficiency. Its fluorinated structure contributes to higher oxidation resistance, making it suitable for high-voltage battery systems. Additionally, it acts as a green solvent in some organic reactions due to its high polarity and biodegradability.
