NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing comprehensive information about the advanced materials we supply. Lithium Bis(trifluoromethanesulfonyl)imide (LiTFSI) is a sophisticated chemical compound with a precise set of properties that make it highly desirable for high-performance battery electrolytes. Understanding these characteristics is crucial for formulators and engineers working in the battery industry.

At its core, LiTFSI is a salt composed of a lithium cation (Li+) and a bistriflimide anion ([N(SO2CF3)2]-). This structure contributes to its hydrophilic nature and its excellent solubility in a range of solvents, including water, which is key for aqueous battery systems. The molecular weight of LiTFSI is approximately 287.09 g/mol, and its purity levels, often exceeding 99.5% when sourced from NINGBO INNO PHARMCHEM CO.,LTD., are critical for optimal electrochemical performance.

One of the most significant properties of LiTFSI is its exceptional electrochemical stability. This high stability window allows it to remain intact and functional across a wide range of operating potentials, preventing unwanted side reactions that can degrade battery performance and lifespan. This is particularly important in next-generation lithium-ion batteries that operate at higher voltages. Coupled with its high ionic conductivity, LiTFSI ensures efficient ion transport, which is fundamental for achieving high power density in batteries.

Another critical aspect is its behavior at elevated temperatures and its interaction with current collectors. Unlike some other lithium salts, LiTFSI exhibits low corrosivity towards aluminum current collectors, even at potentials above 4.2V. This property enhances the safety and reliability of the battery system. The material typically appears as a white solid, with a melting point around 236°C, indicating its thermal stability. Proper storage, as recommended for moisture-sensitive compounds, is essential to maintain its integrity and performance characteristics, such as storing it in a cool, dry, and sealed environment.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that the LiTFSI we provide meets these rigorous specifications, empowering our clients to develop advanced battery technologies with confidence.
