What is Lithium sulfide?
Lithium sulfide, molecular formula: Li2S, is lithium sulfide, molecular weight: 45.95. White to yellow crystals. It has an anti-fluorite structure. The specific gravity is 1.66 (water = 1), the melting point is 938°C, and the boiling point is 1372°C. It is easily soluble in water, soluble in ethanol, soluble in acid, and insoluble in alkali. It can be used as a potential electrolyte material in rechargeable lithium-ion batteries.
Lithium sulfide easily absorbs water vapor in the air and hydrolyzes, releasing highly toxic hydrogen sulfide gas. Hydrogen sulfide can be liberated by acid; it can react violently with nitric acid, but hydrobromic acid and hydroiodic acid can only decompose it when heated. It reacts slowly with concentrated sulfuric acid but reacts violently with dilute sulfuric acid. When heated to about 300°C in the air, it is oxidized by oxygen, but does not generate sulfur dioxide, but generates lithium sulfate.
Is Li2S a strong electrolyte? 
Lithium sulfide Is A Strong Electrolyte Because It Is A Soluble Salt. It Is A Nonelectrolyte Because It Is A Molecular Compound. It is an inorganic compound with the molecular formula Li2S. It crystallizes in the anti-fluorite pattern and is called salt (Li +) 2S2-. It forms a solid yellow-white deliquescent powder. 
How to make lithium sulfide?
Lithium sulfide can be prepared by a variety of methods. In the past, lithium and sulfur were used to heat together to react, and carbon or hydrogen was used to reduce lithium sulfate under heating to prepare lithium sulfide. Later, it was discovered that lithium and sulfur can act in liquid ammonia, or lithium ethoxide can decompose the ethanol adduct of lithium hydrosulfide to produce lithium sulfide. Afterward, some people used lithium pentoxide and hydrogen sulfide to react first to prepare lithium hydrogen sulfide, and then make lithium hydrogen sulfide decomposed by heating in a vacuum to prepare lithium sulfide.
High-quality anhydrous lithium sulfide can be produced by reacting metallic lithium with hydrogen sulfide in tetrahydrofuran.
Storage method and use of lithium sulfide
Lithium sulfide should be stored in a closed and dark place at room temperature, in a ventilated and dry place.
Lithium sulfide can be used as a potential electrolyte material in rechargeable lithium-ion batteries.
Toxicological data of lithium sulfide
Lithium sulfide is irritating to the skin and eyes. At the same time, it also has a sensitizing effect.
