Application
氟化锂可用于：
- 作为添加剂，制造用于锂离子电池的SiO@C/石墨复合阳极材料。氟化锂能稳定固体电解质界面（SEI），并提高初始库仑效率。
- 作为SEI中的一个关键组分，用于稳定SEI层并提高锂金属电池的循环效率。
- 用于制造高效n型晶体硅太阳能电池的电子接触件。
- 用于制备辐射成像探测器的固态光源。
- 用于合成不对称超级电容器应用的高度结晶MXene。此外，还用于制备具有合理强度、高导电性和出色电磁干扰屏蔽性能的轻质、柔性和疏水性MXene泡沫。
- 作为电子注入层，用于制造具有20%量子效率的ITO/PEDOT:PSS/钙钛矿/B3PYMPM/LiF/Al OLED器件。
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.
