Industrial Applications of SodiuM bis(trifluoroMethylsulfonyl)iMide
| Industry | Application | Process |
|---|---|---|
| Lithium-ion batteries | Electrolyte additive to enhance high-temperature stability and cycling performance | Blended with carbonate solvents (e.g., EC/DMC) and lithium salts (e.g., LiPF₆) to formulate electrolytes |
| Organic synthesis | Strong, non-nucleophilic base for deprotonation reactions | Used at low temperature (−78 °C) in anhydrous THF or ether to treat substrates containing acidic hydrogens (e.g., ketones, sulfones, sulfoxides) |
| Electrochemical plating | Electrolyte component for electrodeposition of light metals such as magnesium and aluminum | Used synergistically with Mg(TFSI)₂ or Al(TFSI)₃ for constant-current or constant-potential electrodeposition under inert atmosphere |
| Ion liquid preparation | Anion precursor for synthesizing TFSI⁻-containing ionic liquids | Undergoes anion exchange with imidazolium, pyridinium, or quaternary ammonium halide salts (e.g., via AgTFSI method or K₂CO₃ neutralization) |
| Solid-state electrolytes | Dopant component in sodium-ion battery solid-state electrolytes to improve Na⁺ transference number | Blended with poly(ethylene oxide) (PEO) and NaTFSI, hot-pressed into films, and vacuum-dried at 100 °C prior to use |
Manufacturing Quality Control of SodiuM bis(trifluoroMethylsulfonyl)iMide
| Detection Item | Common Analytical Method | Method Overview |
