Lithium Sulfide For Lithium Batteries

Product advantages

The main advantages of lithium sulfide (Li2S) include its high chemical stability, low fire risk, and low toxicity. ‌

High chemical stability: Lithium sulfide has high chemical stability and is not prone to violent reactions with most common substances. During storage and use, lithium sulfide does not rapidly decompose or release harmful gases, making it relatively safe to handle and store.

Low fire risk: Lithium sulfide itself is a non flammable substance with a high ignition point, so it will not cause a fire under normal circumstances. Compared to other lithium metal compounds, lithium sulfide has a lower risk of fire.

Low toxicity: Under normal conditions, lithium sulfide does not have direct toxic effects on the human body. However, if lithium sulfide is ingested or inhaled in large quantities, it may have certain health effects, such as difficulty breathing, coughing, eye irritation, etc.

Widely used: Lithium sulfide can be used as a positive electrode material for lithium-ion batteries, with advantages such as light weight, good conductivity, low cost, and wide material sources. In addition, lithium sulfide can also serve as a potential electrolyte material in rechargeable lithium-ion batteries.

High purity requirements: Battery grade lithium sulfide has high requirements for purity and particle size, usually requiring a purity of 99.99% or higher and particle size of nanometer or micrometer level.

In summary, lithium sulfide has significant advantages in the field of battery materials due to its high chemical stability, low fire risk, and low toxicity, especially in the application prospects of lithium-ion batteries and rechargeable batteries.
