What is lithium sulfide and how can it be used? Lithium Sulfide It is a yellow to white crystal with an inverse fluorite arrangement. Li2S, which is a lithium sulfide, is the molecular formula. The molecular mass of lithium sulfide (45.95) is equal to 1.66. The melting point for lithium sulfide at 938degC is 1372degC. Lithium sulfide can be easily dissolved in water, ethanol and solubles in acid. It is also insoluble in alkali. Rechargeable lithium-ion batteries can use lithium sulfide as an electrolyte.
Lithium sulfide’s physical and chemical characteristics
Physical properties
You can find white or yellow crystals.
Features an anti-fluorite design
The specific gravity is 1.66 (water = 1); the melting point at 938degC is 938degC and the boiling point at 1372degC are both 1.66.
Water soluble, soluble, ethanol soluble, soluble, acid soluble, insoluble, alkali insoluble.
Chemical nature
Lithium sulfide is able to absorb water vapor from the air and hyrolyzes, releasing highly poisonous hydrogen sulfide.
Separating lithium sulfide with acid can liberate hydrogen sulfuride. It can also react violently to nitric acids, but it can only be decomposed by heating it. Hydrobromic acid or hydroiodic can do this. It reacts slowly and violently with concentrated sulfuric, but not with dilute. When heated to around 300°C in air, it becomes oxidized by oxygen but doesn’t produce sulfur dioxide. Instead, it produces lithium sulfate.

Preparation for lithium sulfide
You can prepare lithium sulfide in a number of ways. The preparation of lithium sulfide was possible in the past by heating sulfur and lithium together. In order to produce lithium sulfide, carbon or hydrogen were used under heat to reduce the lithium-sulfate. It was later discovered that lithium and sulfur could act together in liquid ammonia. Or, lithium ethoxide may decompose lithium hydrosulfide’s ethanol adduct to create lithium sulfide. Some people then combined hydrogen sulfide with lithium pentoxide in order to first prepare lithium hydrogen, sulfide. Next, the vacuum heating was used to decompose lithium hydrogen, sulfide.
Anhydrous lithium sulfide is a high-quality product that can be made by reacting metallic lithium and hydrogen sulfide with tetrahydrofuran.
Application of lithium sulfide
Lithium sulfide is mostly used as an electrolyte in rechargeable lithium ion batteries.
Precautions and storage of lithium sulfide
Lithium Sulfide is able to absorb water vapor from the air and hyrolyzes it, releasing highly toxic hydrogen sulfuride gas. It must be kept at room temperatures in a dry, dark area.
Hydrogen sulfuride can cause slight harm to water bodies. Do not expose large amounts or undiluted products to groundwater or sewers.

Irritation: The effects above the eyes
Sensitization: There is no known sensitization
