Fluoroethylene carbonate (FEC) is the main electrolyte additive for lithium-ion batteries. It has better performance in forming the SEI film, forms a compact structure layer without increasing impedance, can further decomposition of electrolyte, and improve low-temperature performance of electrolyte.
