Descrizione

Descrizione generale

Lithium fluoride is a white crystalline solid with a high melting point. It is widely applied in the field of rechargeable batteries, storage devices, and thermoluminescent materials. LiF is also used as a coupling layer in OLED or PLED devices to enhance electron injection. On the other hand, it is preferred for optical applications due to its wide band gap, which allows it to transmit light efficiently.

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.

Applicazioni

Lithium fluoride can be used:

• As an additive to fabricate SiO@C/graphite composite anode materials for Li-ion batteries. LiF stabilizes solid electrolyte interphase (SEI) and enhances initial coulombic efficiency.
• As a critical component in SEI for stabilizing the SEI layer and improving the cycling efficiency of Li metal batteries.
• To fabricate electron contacts for high-efficiency n-type crystalline silicon solar cells.
• To prepare solid-state light sources for radiation imaging detectors.
• To synthesize highly crystalline MXene for asymmetric supercapacitor applications. And also, lightweight, flexible, and hydrophobic MXene foam with reasonable strength, high electrical conductivity, and an outstanding EMI-shielding performance.
• As an electron-injection layer to fabricate ITO/PEDOT:PSS/perovskite/B₃PYMPM/ LiF/Al OLED device with a quantum efficiency of 20%.
