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.[1]

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.[2]
  • To compose unique nonflammable electrolyte, having thermal stability beyond 200°C and a remarkably high transference number, for lithium-ion batteries.[3]
  • As electrolyte for the Li-O2 batteries.[4]
  • To compose the solid polymer electrolytes for lithium batteries.[5]
