Sodium sulfide is an essential inorganic chemical widely used in the wet purification process of lithium battery recycling.

It is mainly used to precipitate and separate heavy metal impurities in the material liquid, effectively removing harmful miscellaneous components from raw battery materials.

It can assist in optimizing the purification effect of metal solutions and improve the quality of refined products in production.

It is also commonly used for solution preparation and process debugging in laboratory and pilot production experiments of recycling factories.
