Lithium sulfide chemical properties

It is easy to absorb water vapor and hydrolyze in the air, releasing highly toxic hydrogen sulfide gas. It can be decomposed by acid to release hydrogen sulfide; it can react violently with nitric acid, but hydrobromic acid and hydroiodic acid can only decompose it under heating. It reacts slowly with concentrated sulfuric acid, but reacts violently with dilute sulfuric acid. When heated to about 300°C in air, it is oxidized by oxygen, but does not generate sulfur dioxide, but generates lithium sulfate.

Lithium sulfide preparation method

Lithium sulfide can be prepared by a variety of methods. In the past, lithium and sulfur have been co-heated for reaction, and lithium sulfide has been prepared by reducing lithium sulfate with carbon or hydrogen under heating conditions. Later, it was found that lithium sulfide can be obtained by the action of lithium and sulfur in liquid ammonia, or by the decomposition of lithium ethoxide into the ethanol adduct of lithium hydrosulfide. Since then, some people have used lithium pentoxide to react with hydrogen sulfide to first obtain lithium hydrosulfide, and then decompose lithium hydrosulfide in vacuum to prepare lithium sulfide.

High quality anhydrous lithium sulfide can be prepared by reacting metallic lithium with hydrogen sulfide in tetrahydrofuran.

Overview of lithium sulfide Li2S powder

Lithium sulfide is an inorganic compound with the molecular formula Li2S. It will crystallize in the form of anti-fluorite, called the salt (Li+)2S2-. A solid yellow-white deliquescent powder formed. In the air, hydrogen sulfide (the smell of rotten eggs) is easily released. Lithium sulfide is a lithium source that is moderately soluble in water and acid for sulfate-compatible uses. Sulfate compounds are sulfate salts or esters formed by replacing one or two hydrogens with a metal.

Hydrogen sulfide can be released by acids. It can react with nitric acid solution, but hydrobromic acid and hydroiodic acid can only be oxidized by oxygen without producing sulfur dioxide when heated to about 300 ℃ in air. is the formation of lithium sulfate.

Lithium sulfide Li2S powder is generally mildly hazardous to water bodies. Do not expose unreplaced or large quantities of product to the ground, waterways or sewage systems, and trust that the government will not allow the material to be released into the surrounding environment.

Application of lithium sulfide Li2S powder

Lithium sulfide (Li2S) is a product specially designed for high-performance batteries and can be used as an electrode material or as a precursor for solid electrolytes. As an electrode material, it not only has high capacity, but also overcomes many problems brought by pure sulfur electrodes.

The lithium sulfide Li2S powder is an anti-fluorite semiconductor (with a band gap of 3.865 eV). It exists in orthogonal and cubic structures. The densities of the orthorhombic and cubic structures are 1.75g/cm3 and 1.63g/cm3, respectively.

Lithium sulfide Li2S powder has been studied as a superconductor similar to MgB2. It is also used as a cathode material for rechargeable lithium-sulfur batteries.
