Preparation method of lithium sulfide

According to statistics from China Chemical and Physical Power Supply Industry Association, China's export volume and export value of lithium-ion batteries have continued to increase. In 2021, China's exports of lithium-ion batteries were 3.428 billion, with a year-on-year growth of 54.34%. The export of lithium-ion batteries was 28.428 billion DOLLARS, up 78.34% year on year. 

From the battery export destination, so far. China's lithium-ion batteries are mainly exported to the Asia Pacific and the United States and other places. In terms of price, the price of lithium sulfide Li2S, lithium sulfide Li2S overview, lithium sulfide Li2S application, lithium sulfide Li2S suppliers, lithium sulfide Li2S price, led by lithium-ion batteries, is expected to expand globally. 

Overview of lithium sulfide Li2S powder

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.

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.

As the duration of the conflict between Russia and Ukraine grows, its impact on commodities is widening amid the tug-of-war. Recently, European and American sanctions against Russia have been issued one after another. In response, Russia has taken advantage of its role as an important supplier of many energy and commodities, requiring exports of commodities, including energy, grain, metal, and wood, to "unfriendly" countries to be settled in robles. Therefore, it is expected that the price of the lithium sulfide Li2S, lithium sulfide Li2S overview, lithium sulfide Li2S application, lithium sulfide Li2S suppliers, lithium sulfide Li2S price will continue to increase.
