Used as an electrolyte additive in lithium-ion batteries to enhance performance and stability. It helps improve the battery's cycle life and safety by forming a stable solid-electrolyte interface (SEI) layer. Also employed in organic synthesis as a fluorinating agent or catalyst in various reactions. In electrochemistry, it serves as a supporting electrolyte in non-aqueous systems for studying redox processes. Additionally, it finds application in the preparation of perovskite materials for solar cells, contributing to improved efficiency and durability.
