Lithium Sulfide Li2S:
lithium sulfide formulais li2S. Molecular weight of 45.95. It is a white to yellow crystal. It has an antifluorite structure. The melting point and boiling point are 938degC (938 = water) and 1372degC (1372 = 1372).
What occurs when sulfur reacts lithium?
It forms a solid, yellow-white powder. Cocoa, which is easily soluble with water, can be used to make a lithium-ion battery electrolyte.
What kind of bond is lithium sulfuride?
Ionic Bond Inorganic lithium sulfide, which crystallizes to form a powder.
What is the strength of Li2S as an electrolyte?
It’s a strong, electrolyte since it is a salt that dissolves. It’s a non-electrolyte since it’s a molecular substance.
Lithium-sulfide, or Dilithium-sulfide, is an inorganic chemical compound with the molecule formula Li2S. It is a salt of (Li+) 2S2-. It appears as a yellow-white powder.
What is the strength of Li2S as an electrolyte?
It is a strong Electrolyte, because it is a soluble salt. It’s a nonelectrolyte, because it’s a molecule. Hydrogen sulfide is easily released in the air (rotten egg smell). Lithium Sulfide can be used in applications compatible with sulfates. It is water- and acid-soluble. Sulfate salts and esters are formed when one or both hydrogens of sulfuric acids are replaced with a metal.
Does Li2S have a covalent or an ionic character?
This short animation shows the formation of the ionic Bond in lithium sulfide Li2S.
The hydrogen sulfide is liberated when the acid is heated. It is to produce lithium sulfate.
Water bodies are usually only slightly affected by lithium sulfide. Do not let large quantities of unreplaced products, or those that are not regularly replaced, fall on the ground or into waterways.

How does Lithium Sulfide (Li2S) Powder get produced?
There are only a few methods to synthesize lithium sulfide. The most popular synthetic methods include:
In the first way, sulfur powder is added to a tetrahydrofuran liquid containing lithium triethylborohydride. The reaction is completed and the solid powder separated from the liquid in order to get lithium sulfide.
In the second method (Tao Shengdong: a method to prepare lithium sulfide), sulfur powder and metal-lithium powder are mixed with an organic liquid. After sufficient reaction, solid powder is separated to produce lithium sulfide. Both methods use toxic and harmful solvents that are costly and have low productivity.
Lithium sulfide is also produced by high-temperature calcination, which takes place at 800degC.
The lithium sulfide produced by sulfur treatment is called Lithium sulfide. This reaction is easily carried out using anhydrous ammonia.
2 Li + Li2S
Super hydride can be used to produce the lithium sulfide triethyl-borane adduct that is THF soluble.

Lithium Sulfide Li2S: Applications
Lithium sulfide, or Li2S, is a material that can be used to make solid electrolytes and electrodes. For what is lithium-sulfide? It is used to make high-performance batteries. Lithium sulfide can be applied either as an electrolyte or a precursor. It is a high-performance electrode material that overcomes the many problems of pure sulfur electrodes.
The electrode material is not only high-capacity but also eliminates the many problems associated with pure sulfur electrodes.
Lithium Sulfide (anti fluorite) is a semiconductor with a bandgap as low as 3.865eV. It can be found in cubical and orthorhombic forms. Densities are 1.75g/cm3 for cubic and orthorhombic shapes, and 1.63g/cm3 for orthorhombic.
The superconductor Lithium Sulfide was studied in the same way as MgB2- It’s also used in the cathode of rechargeable lithium-sulfur battery.

Storage Conditions of Lithium Sulfide Li2S:
Lithium Sulfide Li2S is affected by dampness, which will reduce the performance of Li2S powder and its use. Therefore, Lithium Sulfide Li2S must be stored in a room that’s cool and dry, and should not be exposed air. Li2S powder must also not be exposed to stress.

Packing & Shipping for Lithium-Sulfide Li2S powder:
Lithium Sulfide Li2S is available in a variety of different packings.
Lithium Sulfide (Li2S) Powder Packaging: Vacuum packed, 100g,500g or 1kg/bag.
Once payment is received, Lithium Sulfide (Li2S) Powder can be shipped by sea, air or express.
