Solvay LiTFSI (lithium bis-trifluoromethanesulfonimide) is the lithium salt market reference with outstanding electrochemical properties, high stability (chemical and thermal) that ensure safety and performance to its main end-use applications: electrical vehicles, e-bikes, flat panel screens, smartphone, laptop & powertools. TFSILi shows outsanding electrochemical properties and high thermal stability. It used in many applications, mainly as antistatic agents, or as electrolyte salt for batteries. 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.
