The continuous drive for innovation in battery technology necessitates the exploration and adoption of advanced materials. Lithium Bis(fluorosulfonyl)imide (LiFSI) has emerged as a standout electrolyte salt, offering a unique combination of properties that significantly improve lithium-ion battery performance. This article provides an in-depth look at the key characteristics of LiFSI and explains why sourcing this material from specialized manufacturers is crucial for technological advancement.

At its core, LiFSI is a white crystalline powder with a molecular formula of F2NO4S2.Li and CAS number 171611-11-3. Its high purity, often exceeding 99%, is fundamental to its effectiveness. A critical property is its thermal stability, with no decomposition observed below 200°C, a stark contrast to some other common electrolyte salts. This inherent stability is a cornerstone for designing safer and more robust battery systems.

The electrochemical advantages of LiFSI are equally impressive. It demonstrates excellent low-temperature performance, enabling batteries to operate efficiently even in frigid conditions. This is achieved by its ability to effectively reduce the high and low-temperature resistance of the SEI (Solid Electrolyte Interphase) layer formed on electrode surfaces. Furthermore, its good hydrolysis stability contributes to reduced capacity loss during battery storage, thereby extending the overall lifespan and reliability of the battery.
