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.

Articles

Dr. Schmuch, Dr. Siozios, Professor Dr. Winter, and Dr. Placke review the challenges and opportunities of nickelrich layered oxide cathode materials. They discuss production processes for the layered oxide cathode materials as well as their chemistry and morphology.

The critical technical challenges associated with the commercialization of electric vehicle batteries include cost, performance, abuse tolerance, and lifespan.

Lithium-ion batteries (LIBs) have been widely adopted as the most promising portable energy source in electronic devices because of their high working voltage, high energy density, and good cyclic performance.

Due to the adverse impact of the continued use of fossil fuels on the earth’s environment and climate, researchers have been asked to develop new approaches for producing power using renewable sources like wind and solar energy
