Descrição

Descrição geral

Anhydrous fluoroethylene carbonate (FEC) is a synthetic, organic compound that belongs to the class of compounds known as carbonates. It is a clear, colorless liquid that is highly stable and resistant to hydrolysis, making it an ideal choice for use in a variety of chemical reactions and processes. Fluoroethylene carbonate is typically produced by the reaction of fluoroacetic acid and carbon dioxide.

Aplicação

Anhydrous battery-grade fluoroethylene carbonate (FEC) is an essential ingredient in high-quality lithium-ion battery electrolytes. Its unique properties, such as its ability to form a stable SEI layer on the anode, help improve the safety, reliability, and performance of lithium-ion batteries. In particular, the addition of battery-grade FEC to the electrolyte can significantly enhance the rate capability, capacity retention, and low-temperature performance of lithium-ion batteries. Battery-grade FEC is compatible with a range of materials used in lithium-ion batteries, including lithium metal, graphite, silicon, and metal oxide cathodes, making it a versatile electrolyte additive. As the demand for high-performance lithium-ion batteries continues to grow in various applications, including electric vehicles and portable electronics, the use of battery-grade FEC as an electrolyte additive is becoming increasingly important in the development of advanced battery technologies.

Características e benefícios

Fluoroethylene carbonate can enhance battery safety and improve performance. Adding battery-grade FEC to the electrolyte can significantly enhance cycle life, capacity retention, and low temperature performance compared to batteries without FEC.
✔ Improves Battery Safety
✔ Enhances Battery Performance
✔ Versatile Electrode Compatibility
