Application

Lithium fluoride can be used as an electron injection layer in the fabrication of electroluminescent devices.

It can be used as an electrolyte additive to protect the lithium metal electrode, which improves the stability and reversibility of the battery. The partially soluble LiF forms a thin coating over the surface of lithium and stabilizes the SEI layer.

It can also be used as catalyst support in the preparation of carbon nanofibers by a catalytic chemical vapor deposition method.

Features and Benefits

  • High mechanical strength
  • Wide electrochemical stability window
  • Low calculated barriers toLi diffusion
