| Application: | 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/ |
| Features and Benefits: | • High purity in lithium fluoride is vital for the best performance and lifespan of lithium-ion batteries, helping to reduce degradation from metal impurities. • The presence of metal impurities such as calcium, sodium, and iron at levels below 10 ppm helps maintain optimal battery performance . • High purity lithium fluoride enhances electrochemical efficiency by ensuring optimal ionic conductivity, minimizes side reactions that degrade battery materials, contributes to stable electrolyte formulations for improved longevity and cycle life, and reduces the risk of hazardous reactions during battery operation, thereby enhancing safety and reliability. • Low moisture content (114ppm) improves the performance of LiF in high-temperature or high-humidity environments, making it suitable for a wider range of applications. • High purity lithium fluoride enhances charge transport for increased solar cell efficiency, maintains material stability for long-term performance, reduces structural defects to improve light absorption, and boosts durability for extended operational life. |
| General description: | 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. |
