General description
硫化锂 粉末是一种高纯度的无机化合物，外观为白色至 淡黄色结晶粉末。其分子量为45.95 g/mo， 密度为1.82 g/cm³。硫化锂是一种强亲核试剂， 化学式为 Li₂S。它容易与水反应形成氢氧化锂 和硫化氢气体。它也可溶于一些有机溶剂， 如吡啶和二甲亚砜。
Application
高纯度的 硫化锂主要可作为前体用于合成其它 锂化合物，如硫代乙酸锂、 四氟硼酸锂和 thio-LISICON，这些物质可用于 锂离子电池和其它应用。高纯度的硫化锂还可直接用于 电池应用，作为锂硫电池的正极材料。硫化锂的 理论容量高达1166 mAh/g，几乎是锂钴氧化物理论容量的四倍， 作为下一代正极材料其受到广泛 关注。 此外，在半导体行业硫化锂可作为前体 用于生产薄膜晶体管（TFT）和其它 电子设备，特别是硫化锂-氧化磷（Li2S-P2O5） TFT。在化学制造行业它也可作为前体用于制造 氢化锂、硼氢化锂和氨基化锂 ，还用于许多其它应用。
Features and Benefits
高纯度-99.98%,令其成为需要较高纯度物质应用的理想选择。

In the search for novel solid electrolytes for solid-state batteries, thiophosphate ionic conductors have been in recent focus owing to their high ionic conductivities, which are believed to stem from a softer, more polarizable anion framework. Inspired by the oft-cited
