General description

Symmetric and aliphatic trialkylsulfonium cations form room temperature molten salts with bis(trifluoromethylsulfonyl)imide.

Application

Triethylsulfonium bis(trifluoromethylsulfonyl)imide is a room-temperature ionic liquid (RTIL ) that can be used:
  • As an electrolyte in electrochemical double-layer supercapacitors.
  • As a model ionic liquid used in the studies of structure effect of ions on electrochemical windows (EWs).
  • As a component of the gel polymer electrolyte, which is used in the construction of symmetrical electrical-double layer capacitors.
  • As an electrolyte in the in-plane supercapacitor devices.
