What are the disposal methods for used batteries?

1 Treatment of mercury-containing storage batteries (dry storage batteries) Dry storage batteries, with regard to storage batteries with low mercury content, are mainly treated by curing methods and then landfilled after curing. Regarding batteries with high mercury content (such as the commonly used carbon-zinc batteries and alkaline zinc-manganese batteries), there are wet and fire treatment methods. Hydrometallurgy includes roasting leaching method and direct leaching method. Pyrometallurgy is divided into atmospheric metallurgy and vacuum metallurgy. At present, Switzerland, Japan, Sweden, the United States and other countries mainly adopt pyrometallurgical processes. 2 Treatment of lead-acid batteries containing batteries The regeneration process of lead-acid batteries used in the early 1990s is mainly divided into casing disintegration and classification (lead powder, lead mud, small pieces of lead alloy, lead slag, regeneration, etc.). In recent years, China There is a new breakthrough in the development of waste battery recycling technology. This technology has the characteristics of high recovery efficiency and low pollution. 3 The treatment of nickel-containing batteries The treatment of nickel-containing batteries is currently available There are two types of dry method and wet method. The dry method mainly uses the characteristics of higher vapor pressure of cadmium and its oxides and the separation of nickel. The wet method uses the difference in the volume product of cadmium sulfide and nickel sulfide to control certain conditions so that nickel, Cadmium separation. 4 Lithium battery treatment The lithium battery treatment process is to first incinerate the battery to remove organic matter, then screen to remove iron and copper, heat the remaining powder and dissolve it in acid, and use an organic solvent to extract cobalt oxide. It can be used as a raw material for pigments and coatings. Statement: Some pictures and content of the articles published on this site are from the Internet.
