Lithium-ion batteries include a variety of toxic substances, high corrosive and pollution. In addition, the lithium-ion battery electrolyte contains a very poisonous, flammable and explosive, corrosive electrolyte and organic solvent, then how to deal with waste lithium ion batteries? The life of the lithium-ion battery is generally three years, currently used There are more and more types of lithium-ion batteries. When recovering, it is also different from the value of the type of lithium ion battery.

In fact, the lithium-ion battery contains a large number of metal copper and lithium powder, which are highly scarce resources. The waste lithium ion batteries on the market will have thousands of tons of production per year. If these recovery will have a very high business value.

Waste lithium-ion batteries are contained in metal elements such as cobalt, lithium, nickel, copper, aluminum and iron. The mass fraction of cobalt ions can be as high as 15%, which is 850 times the cobalt ore content, far exceeding the production of cobalt mines in my country. out.

At the same time, the copper foil of the aluminum foil and the negative electrode fluid as a positive electrode fluid in the structure of a lithium ion battery also has high recovery value. Investing in Kaidi cancer ion battery crusher kits, recovering provals in lithium-ion batteries, reducing pollution caused by environmental pollution, relieving resource lacking, etc., has important social significance and economic significance.

How to treat waste lithium ion batteries Treatment of wet process to treat waste lithium-ion batteries is currently studied more and more mature processes, important experience 3 stages: 1) Thorough discharge of recycled waste lithium ion batteries, simple split breakage Wait pretreatment, after the screening is obtained, an important electrode material is obtained, and then the organic substance is obtained. 2) The electrode material is obtained by dissolving the electrode material obtained after pre-treatment, so that the various metals and their compounds into the leach in the form of ions. China; 3) The separation and recovery of metals in the leaching liquid is the key and difficult to study the waste lithium-ion battery treatment process.

At present, the method of separating and recovery is important with solvent extraction, precipitation, electrolysis, ion exchange method, salting and etiology. .
