Lithium Sulfide Properties
About Lithium Sulfide Li2S Powder:
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. Easily soluble in water, cocoa can be used as a potential electrolyte material in rechargeable lithium-ion batteries.
Lithium sulfide 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. In the air, it is easy to release hydrogen sulfide (Rotten egg smell). Lithium Sulfide is a moderately water and acid soluble Lithium source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal.
It can be liberated by acid to liberate hydrogen sulfide; it can react with a nitric acid solution, but hydrobromic acid and hydroiodic acid can only be oxidized by oxygen when heated to about 300°C in the air, but no sulfur dioxide is generated. Is to generate lithium sulfate.
Lithium sulfide is usually slightly harmful to water bodies. Do not expose unreplaced or large amounts of products to the ground, waterways or sewage systems, and think that the government allows not to discharge materials into the surrounding environment. Feel free to send an inquiry to get the latest price if you would like to buy Lithium Sulfide Li2S Powder in bulk.

How is Lithium Sulfide Li2S Powder produced?
There are few synthetic methods for lithium sulfide, and the most common synthetic methods are mainly as follows:
In the first method, the sulfur powder is put into a tetrahydrofuran solution containing lithium triethylborohydride, and after a full reaction, the solid powder is separated from the liquid to obtain lithium sulfide;
In the second method, sulfur powder and metal lithium powder are added to an organic solvent, and after sufficient reaction, the solid powder is separated from the liquid to obtain lithium sulfide (Tao Shengdong, a method for preparing lithium sulfide). Both of the above two types of methods require the use of toxic and harmful solvents, which have low efficiency and high cost, and are difficult to achieve industrial production.
In addition, using lithium sulfate and coke as raw materials, lithium sulfide can also be obtained by the high-temperature calcination method at 800-900°C.
Lithium sulfide is prepared by treating lithium with sulfur. This reaction is conveniently conducted in anhydrous ammonia.
2 Li + S → Li2S
The THF-soluble triethyl borane adduct of lithium sulfide can be generated using super hydride.

Applications of Lithium Sulfide Li2S Powder:
Lithium sulfide (Li2S) is a product specially designed for use in high-performance batteries which can be either applied as an electrode material or as a precursor for solid electrolytes. It as an electrode material not only has high capacity but also overcomes many problems caused by pure sulfur electrodes.
Lithium sulfide is an anti fluorite semiconductor (bandgap 3.865eV). It exists in orthorhombic and cubic structures. The densities of the orthorhombic and cubic structures are 1.75g/cm3 and 1.63g/cm3 respectively.
Lithium sulfide has been studied as an MgB2- like superconductor. It is also used as a cathode material in rechargeable lithium-sulfur batteries.

Storage Condition of Lithium Sulfide Li2S Powder:
Damp reunion will affect Li2S powder dispersion performance and using effects, therefore, Lithium Sulfide Li2S Powder should be sealed in vacuum packing and stored in cool and dry room, the Lithium Sulfide Li2S Powder can not be exposure to air. In addition, the Li2S powder should be avoided under stress.

Packing & Shipping of Lithium Sulfide Li2S Powder:
We have many different kinds of packing which depends on the Lithium Sulfide Li2S Powder quantity.
Lithium Sulfide Li2S Powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Lithium Sulfide Li2S Powder shipping:could be shipped out by sea , by air, by express?as soon as possible once payment receipt.
