Application

Lithium trifluoromethanesulfonate can be used:
  • As an electrolyte salt to determine the thermal stability of graphite anodes in Li-ion batteries.
  • For the synthesis of solid polymer electrolytes with polyethylene oxide and chitosan, having potential applications in solid state batteries.
  • As a source of triflate anion (CF3SO3−) to synthesize ionic liquids for further syntheses of conducting polymer electrolytes.

Lithium-sulphur batteries with a high theoretical energy density are regarded as promising energy storage devices for electric vehicles and large-scale electricity storage. However, the low active material utilization, low sulphur loading and poor cycling stability restrict their practical applications. Herein
