General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more information.

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

Complex Hydrides: A New Category of Solid-state Lithium Fast-ion Conductors

Research and development of solid-state lithium fast-ion conductors is crucial because they can be potentially used as solid electrolytes in all-solid-state batteries, which may solve the safety and energy-density related issues of conventional lithium-ion batteries that use liquid (farmable organic) electrolytes.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
