Application

Fluoroethylene carbonate serves primarily as an electrolyte additive for lithium-ion batteries. This clear, colorless liquid boasts a high dielectric constant, which helps in the dissociation of lithium salts, and its fluorine atoms enhance integration within battery systems. These properties contribute to better battery capacity and enhanced performance at low temperatures. By forming a thin and stable solid electrolyte interphase (SEI) layer, it improves cycling efficiency and discharge capacity retention, thereby enhancing the specific capacity, cycle stability, and cycle life of lithium-ion batteries. Additionally, this substance is utilized as an intermediate in organic synthesis and other applications, such as electronic chemicals and pharmaceutical intermediates, but its main role lies in increasing the range, service life, and safety of lithium-ion batteries.
