LiTFSI as Electrolyte salt

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
