Vinylene carbonate is widely used as an electrolyte additive in lithium-ion batteries. It improves the stability and performance of the battery by forming a protective solid electrolyte interphase (SEI) layer on the anode surface. This SEI layer helps reduce electrolyte decomposition, enhances cycle life, and increases thermal stability. It is especially effective in batteries with graphite anodes, where it contributes to better charge-discharge efficiency and safety. Additionally, vinylene carbonate can be used in polymer synthesis and as a crosslinking agent in specialty resins, where it imparts improved mechanical and thermal properties.
