Ethylene Sulfate 1072-53-3 C₂H₄O₄S

Ecovia Company has established itself as a key innovator in lithium-ion battery electrolyte additives, specializing in battery grade Ethylene Sulfate (1,3,2-dioxathiolane-2,2-dioxide, CAS 1072-53-3).

  Application  

Ethylene Sulfate is used in lithium-ion batteries primarily as an electrolyte additive. Its role is to enhance the stability and performance of the battery. When added to the electrolyte solution, ethylene sulfate can help improve the formation of the solid electrolyte interface (SEI) on the anode, which is crucial for the long-term cycling stability of the battery.
The SEI layer acts as a protective barrier between the electrolyte and the anode, preventing unwanted side reactions. Ethylene sulfate helps to optimize the structure and composition of this layer, which can lead to improved charge/discharge efficiency, reduced capacity fading, and better overall battery life. Additionally, it can contribute to the thermal stability of the battery, making it more resistant to overheating and degradation.
 In summary, ethylene sulfate helps improve the safety, longevity, and performance of lithium-ion batteries by enhancing the SEI layer and stabilizing the electrolyte.
