For professionals in the chemical and battery industries, a thorough understanding of key compounds is essential for innovation and product development. NINGBO INNO PHARMCHEM CO.,LTD., a prominent supplier of fine chemicals, provides insights into Bis(2,2,2-trifluoroethyl) carbonate (TFEC), CAS 1513-87-7. This article delves into the fundamental chemical properties of TFEC, its molecular structure, and its critical applications, particularly as a high-purity electrolyte additive for lithium-ion batteries. Understanding these attributes is vital for researchers and purchasing managers looking to source this advanced material.

Bis(2,2,2-trifluoroethyl) carbonate, also known by its CAS number 1513-87-7, possesses the molecular formula C5H4F6O3 and a molecular weight of approximately 226.07. The presence of two trifluoroethyl groups attached to the carbonate core is central to its unique properties. These fluorine atoms significantly influence its polarity, thermal stability, and electrochemical behavior. As a colorless, transparent liquid, TFEC's purity is typically maintained at 99% or higher, ensuring its suitability for high-demand applications like lithium-ion battery electrolytes, where even trace impurities can negatively impact performance and safety.

The chemical structure of TFEC enables it to act as an effective flame retardant. The fluorine atoms contribute to a higher decomposition temperature and can quench radical chain reactions that propagate combustion. In the context of lithium-ion batteries, this property is invaluable for preventing thermal runaway. Furthermore, TFEC's interaction with electrode surfaces and its ability to form a stable solid electrolyte interphase (SEI) layer contribute to improved cycle life and the prevention of dendrite formation, which is crucial for battery longevity and safety.
