High Purity Lithium Sulfide Li2S Powder CAS 12136-58-2, 99.99%

Description of Lithium Sulfide：

Lithium Sulfide is an organic compound whose formula is Li2S, usually produced in industry by the reaction of lithium and sulfur under certain conditions.

In terms of physical properties, lithium sulfide presents as a gray solid powder with a high melting point of 1245°C and a high vapor pressure. In the air, lithium sulfide easily absorbs moisture and becomes a viscous liquid. It is also slightly soluble in water but insoluble in organic solvents.

In terms of chemical properties, lithium sulfide has high chemical stability, and it is easy to absorb moisture in the air into a viscous liquid. However, if exposed to moisture, lithium sulfide will gradually oxidize to form lithium sulfate.

Lithium sulfide is used in industry as a raw material for the production of lithium metal. Lithium metal can be used to manufacture high-energy batteries, missiles, rocket fuels, and other military items. It can also be used to produce high-energy fuel, synthetic ammonia catalysts, and other civilian products. Therefore, lithium sulfide has a wide range of applications in both national defense and civil fields.

In addition, lithium sulfide is also used as a raw material for lithium salt production. For example, it can be used to produce lithium salts such as lithium sulfate, lithium carbonate, and lithium hydroxide. These lithium salts are widely used in glass, ceramics, greases, leather, photography, medicine, and other fields.

At the same time, lithium sulfide can also be used as electrode materials in electrochemistry. For example, it can be used as a negative electrode material in lithium batteries and a positive electrode material in peroxide fuel cells. Due to its high electronegativity, lithium sulfide can form stable complexes with many metal ions, so it is widely used in the field of electrochemistry.

Production Method of Lithium Sulfide：
Direct synthesis

Direct synthesis is a method to produce lithium sulfide by the reaction of lithium metal and sulfur under certain conditions. In this method, lithium metal and sulfur elements are mixed in a certain proportion and then heated to more than 1000 ° C in a high-temperature furnace for a certain time so that lithium and sulfur elements fully react. After the end of the reaction, the product is taken out, and the lithium sulfide product is obtained after washing and drying. The advantage of direct synthesis is that the process is simple and easy to operate, which is suitable for large-scale production. However, this method requires high-temperature conditions, large energy consumption, and high purity requirements for equipment and raw materials, and improper operation is easy cause environmental pollution.

Double salt process

The double salt process is a method of producing lithium sulfide by reacting lithium salt with hydrogen sulfide gas at high temperatures. The method mixes lithium salt and hydrogen sulfide gas in accordance with a certain proportion. Then, it heats to more than 1000℃ in a high-temperature furnace for a certain time so that the lithium salt and hydrogen sulfide gas fully react. After the end of the reaction, the product is taken out, and the lithium sulfide product is obtained after washing and drying. The advantage of the double salt method is that the reaction temperature is lower, the energy consumption is less, and it is suitable for large-scale production. However, this method requires high purity of equipment and raw materials, and improper operation is easy to cause low purity of products. At the same time, hydrogen sulfide gas is toxic, and improper operation can easily cause safety and health problems.

Solvent extraction method

Solvent extraction is a method of extracting lithium ions and sulfur ions from a solution of organic solvent to prepare lithium sulfide. The method mixes lithium ion and sulfur ion in an organic solvent, and then adds extractant so that lithium-ion and sulfur ion are extracted, and then separates the solvent through distillation and other methods to obtain lithium sulfide products. The advantage of solvent extraction is that lithium sulfide can be prepared directly from the solution, beware of harsh reaction conditions like high temperature and high pressure, and can be continuously produced. But, this process calls for using organic solvents, which can lead to environmental harm and security issues.
