Description

Application

Bis(trifluoromethane)sulfonimide lithium salt (Li-TFSI) can be used:

• As a chemical additive for improving the power conversion efficiencies in porphyrin-based organic solar cells.     
• As a reagent in the preparation of imidazolium core bearing monomer ionic liquids to develop polymerized ionic liquids.
• For the preparation of a chiral imidazolium salt via anion metathesis of the corresponding triflate.       
• In the synthesis of solid polymer electrolytes for lithium-ion batteries. 
• In the synthesis of polyelectrolyte reusable homogenous catalysts, which are used in the Diels–Alder reactions between isoprene and a variety of dienophiles.
• Used in the preparation of electrolytes for lithium batteries and novel rare-earth Lewis acid catalysts.
