In the rapidly evolving landscape of energy storage, lithium-ion batteries stand at the forefront. Their performance, longevity, and safety are paramount, and a key factor influencing these attributes is the composition of the electrolyte. Amongst the various components, electrolyte additives play a crucial role, and Fluoroethylene Carbonate (FEC) has emerged as a particularly effective agent. As a leading manufacturer and supplier of specialty chemicals, we understand the critical importance of high-purity FEC for battery manufacturers worldwide.

The primary function of Fluoroethylene Carbonate (CAS 114435-02-8) as an additive is its ability to form a stable Solid Electrolyte Interphase (SEI) layer on the surface of the negative electrode. This SEI layer is fundamental in preventing the continuous decomposition of the electrolyte during charging and discharging cycles. A well-formed SEI layer by FEC leads to several significant performance improvements in lithium-ion batteries:

• Enhanced Battery Capacity: By minimizing electrolyte decomposition, FEC helps preserve the active materials within the battery, leading to a higher usable capacity and better energy density.
• Extended Cycle Life: A stable SEI layer significantly reduces parasitic reactions, thereby slowing down the degradation of battery components and substantially extending the overall cycle life of the battery.
• Improved Low-Temperature Performance: Batteries often suffer from reduced efficiency in cold environments. FEC's presence helps maintain electrolyte conductivity and stability at lower temperatures, ensuring more reliable operation.

The purity of FEC is a critical factor for its effectiveness. Impurities can lead to undesirable side reactions, compromising the SEI layer and negatively impacting battery performance and safety. Our commitment as a manufacturer in China is to provide Fluoroethylene Carbonate with an assay of ≥99.95%. This ultra-high purity ensures that our clients, from R&D scientists to large-scale production managers, receive a product that meets the most stringent demands of advanced battery technology.
