Imidodisulfurylfluoride is widely utilized across next-generation electric vehicle traction battery manufacturing, grid-scale energy storage electrolyte compounding, high-safety solid-state and semi-solid electrolyte engineering, sodium-ion battery conducting salt synthesis, and specialty organofluorine chemical transformations. In advanced electrochemical energy storage and lithium battery processing, universally designated across materials science as HFSI or bis(fluorosulfonyl)imide and cataloged in commercial additive sourcing alongside methylene methanedisulfonate series, it serves as the essential foundational precursor for synthesizing ultra-pure lithium bis(fluorosulfonyl)imide and sodium bis(fluorosulfonyl)imide conducting salts; these salts furnish non-aqueous liquid electrolytes with high ionic conductivity, reduced desolvation energy barriers, and broad thermal operating windows, facilitating the formation of a robust, inorganic-rich solid electrolyte interphase that passivates lithium metal and silicon-graphite anodes against parasitic degradation; this stabilization suppresses cell impedance elevation, prevents gas generation during high-rate cycling, and elevates thermal runaway safety thresholds in fast-charging automotive battery modules; in synthetic fluorine chemistry and catalysis, its strongly electron-withdrawing fluorosulfonyl motifs impart strong Bronsted superacidity, establishing it as an efficient catalyst and functional fluorosulfonyl transfer reagent for selective Friedel-Crafts alkylations and complex molecule derivatizations; furthermore, in specialty dielectric materials, Imidodisulfurylfluoride functions as a versatile fluorinated counterion source for engineering flame-retardant hydrophobic ionic liquid electrolytes and electrochemical sensor interfaces.
