Application

氟化锂(LiF)可作为添加剂掺入锂离子电池电解质，提高热稳定性和电池总体性能。可用作覆盖在电极上的薄膜，通过防止循环降解来提高电极的稳定性和寿命。氟化锂是阳极界面膜的重要成分，其中高模量壳可防止LixSi粉化，高化学稳定性可有效抑制界面副反应。氟化锂因其中子吸收截面和中子俘获能力，适合用于中子屏蔽和检测，可用于核反应堆和辐射探测器中。

氟化锂（LiF）可用作烧结助剂，有助于尖晶石颗粒的蚀刻以降解镁铝尖晶石。它可用于制备锂离子电池用碳铁LiF纳米复合材料电极材料。它还可以在对电极上形成薄的中间层，以提高填充系数并稳定聚合物太阳能电池的高开路电压。

General description

氟化锂(LiF)是功能多样的化合物，广泛用于各种研发领域。独特的理化性质适用于光学器件、电池、核应用、陶瓷、玻璃、光电、冶金、热释光剂量计、催化、环境研究和生物医学应用。
