LiTFSI (or TFSILi) is a key component for Li-ion battery in liquid electrolyte as well as solid electrolyte (LMP batteries) with high ionic conductivity and chemical /thermal stability providing:

  • High battery performance
  • High intrinsic safety thanks to  its chemical and thermal stability 
  • Reduced battery cost over its lifetime
  • No aluminium corrosion
  • Reduced battery filling time with LITFSI used as separator coating

Solvay lithium bis-trifluoromethanesulfonimide can be used as electrolyte additive or main salt. 

Thanks to its historical expertise, Solvay also provides TFSI derivatives that can be used as solvent (ionic liquid) and TA EG as intermediate of synthesis for LiTA for instance.

LiTFSI as Antistatic agent

LiTFSI and its derivatives, such as ionic liquid, acts as antistatic agent in polymer matrix for:

  • Liquid crystal display (LCD) : Protective films (ITO), Polarizer component (PSA films)
  • Electrochromic display (ECD)
  • OLED

Thanks to its optical properties and surface resistivity, our LiTFSI answers the main requirements of 3C markets (Consumer electronics, Computer, Communication): transparency and performance.
