Used as a key electrolyte additive in lithium-ion batteries to enhance performance and stability. It helps improve the battery's cycle life and capacity retention by forming a stable solid-electrolyte interphase (SEI) layer on the anode. This chemical is also employed in advanced electrochemical applications due to its high thermal stability and conductivity. Additionally, it finds use in specialty chemical synthesis where nonafluoroalkyl groups are required for specific reactions.
