General description

Bis(trifluoromethane)sulfonimide lithium salt is a synthetic reagent.

LiTFSI exhibits high ionic conductivity and electrochemical stability. Used as an electrolyte additive in energy storage devices.

Application

Bis(trifluoromethane)sulfonimide lithium salt may be used in the following studies:
  • As ionic liquid in the preparation of gel polymer electrolytes (GPEs) using solution casting technique.
  • To compose unique nonflammable electrolyte, having thermal stability beyond 200°C and a remarkably high transference number, for lithium-ion batteries.
  • As electrolyte for the Li-O2 batteries.
  • To compose the solid polymer electrolytes for lithium batteries.
