General description

Lithium trifluoromethanesulfonate is a class of electrolytic materials that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.

Application

LiOTf can be used for a variety of applications such as:
  • a polymeric layer for light-emitting electrochemical cells
  • an electrolyte for lithium-ion batteries
  • a recyclable catalyst for acetylation of alcohols and diacetylation of aldehydes
  • a separator for supercapacitors

Conjugated polymers containing long-chain alkyl side groups for solubility are generally unstretchable: large strain induces crack formation, fracture, or plastic deformation. When the polymers are stretched to reorient the conjugated chains along the stretching direction, high dichroic ratio is observed
