Vinylethylene Carbonate (VEC) is a highly specialized cyclic carbonate additive used in Lithium-Ion Battery (LIB) electrolytes, primarily for its role in forming an excellent protective layer on the anode. It is closely related to Vinylene Carbonate (VC) but has a more complex structure, offering unique advantages in stabilizing the electrode interfaces, particularly in high-voltage and wide-temperature range applications. The vinyl group contains a double bond that allows VEC to function as an effective SEI-forming agent through polymerization.
