General description

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.

Application

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.

Features and Benefits

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

Caution

  • These electrolyte solutions have extremely low water content; please handle under inert and moisture free environment (glove box).
  • Keep containers tightly closed. Keep away from heat and ignition sources. Store in a cool and dry place. Avoid storing together with oxidizers.
