Description

General description

Lithium fluoride is an inorganic halide with good ionic conductivity, high refractive index, and high transmittance in the UV region. Owing to its unique properties, it is widely used in the field of optical and electronic devices, X-ray imaging, and dental materials.

Application

Lithium fluoride(LiF) can be used:

• To fabricate an insulating layer in AC-driven organic light-emitting diodes(OLEDs). LiF provides excellent capacitance and high stability to the insulating layers in AC devices.
• As a precursor to synthesize Eu²⁺/Ce³⁺ doped barium lithium fluoride phosphors by solvothermal method.
• To fabricate LiF thin film coating on the lithium anodes to enhance their stability and coulombic efficiency.
• As an additive to enrich and enhance the performance of solidelectrolyte interface(SEI) in Li metal batteries.
