Lithium sulfide powder is a high-purity, inorganic compound that appears as a white to yellowish crystalline powder. It has a molecular weight of 45.95 g/mol and a density of 1.82 g/cm. Lithium sulfide is a strong nucleophile and has the chemical formula LiS. It readily reacts with water to produce lithium hydroxide and hydrogen sulfide gas. It is also soluble in some organic solvents, such as pyridine and dimethyl sulfoxide.High-purity lithium sulfide is primarily used as a precursor in the synthesis of other lithium compounds such as lithium thioacetate, lithium tetrafluoroborate, and thio-LISICONs, which are used in lithium-ion batteries among other applications. High-purity lithium sulfide can also be used directly in battery applications as a cathode material in lithium-sulfur batteries. With a theoretical capacity of up to 1166 mAh/g, almost four times that of lithium cobalt oxide, lithium sulfide has gained attention as next-generation cathode material. Additionally, lithium sulfide is used as a precursor in the semiconductor industry for the production of thin-film transistors (TFTs) and other electronic devices, especially lithium sulfide-phosphorus oxide (Li2S-P2O5) TFTs. It is also used in the chemical manufacturing industry as a precursor for lithium hydride, lithium borohydride, and lithium amide, among many other applications.
