The preparation method of lithium sulfide

Lithium Sulfide Overview

Lithium sulfide, molecular formula: Li2S, is lithium sulfide, molecular weight: 45.95. White to yellow crystals. 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. Soluble in water, soluble in ethanol, soluble in acid, insoluble in alkali. as a potential electrolyte material in rechargeable lithium-ion batteries.

The preparation method of lithium sulfide

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.


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.
