Fluoroethylene Carbonate (FEC) is one of the finest electrolyte additives to improve lithium-ion battery strength and performance. Renowned for its ability to build a stable Solid Electrolyte Interphase (SEI) on an anode, FEC assists in the advancement of the battery’s cycling stability, capacity retention as well as overall safety. Optimization of this additive is particularly helpful in systems of high voltage and capacity, where integrity and function over extended charge cycles are required.
With the increase in the demand for long-lasting and high-performance batteries in sectors including electric vehicles (EVs), energy storage systems (ESS), and consumer electronics, FEC assumes a life-saving role in increasing battery efficiency. Its exceptional electrochemical attributes enable it to positively change the stability of the SEI layer considerably, limiting the undesired reactions and avoiding capacity fade. By integrating FEC, producers can manufacture batteries that not only achieve a longer life cycle but also can work safely and effectively in extremes.
