Application
4-Fluoro-1,3-dioxolan-2-one serves as an essential electrolyte additive in lithium-ion batteries, primarily enhancing the performance and longevity of these energy systems. By facilitating the formation of a thin, smooth, and stable solid electrolyte interphase (SEI) layer on the anode, it significantly increases cycling efficiency and retention of discharge capacity. This additive also improves battery capacity and performance at low temperatures due to its high dielectric constant and its ability to better integrate into the battery system thanks to the presence of fluorine atoms. Consequently, 4-Fluoro-1,3-dioxolan-2-one not only inhibits electrolyte decomposition but also contributes to a tightly bonded SEI film, thereby improving the specific capacity, cycle stability, and cycle life of lithium-ion batteries. Its role extends beyond electrochemistry, as it also functions as an intermediate in organic synthesis, underscoring its versatility in various chemical applications.
