800kg/h Lithium Battery Recycling Plant With A Black Mass Recovery Rate Greater Than 97%

In recent years, with the vigorous development of the new energy vehicle industry, the amount of retired power lithium batteries has also increased year by year. How to recycle and treat these retired batteries efficiently and environmentally friendly has become a major challenge facing the industry. As a key material produced in the lithium battery recycling process, the recovery rate of “black mass” is directly related to the economic and environmental benefits of the entire recycling line.

Pain points of traditional recycling process:
The traditional lithium battery recycling process mainly adopts the method of crushing and sorting-hydrometallurgy, that is, the battery is first crushed, and then the positive and negative electrode materials are obtained by physical sorting, and finally the valuable metals are extracted by hydrometallurgical process. However, this method has the following pain points:

• Low black mass recovery rate: In traditional processes, the recovery rate of black mass is generally less than 90%, resulting in waste of resources.
• Environmental pollution risk: A large amount of waste liquid will be generated during the hydrometallurgical process, and improper treatment can easily cause environmental pollution.
• Complex process flow: Traditional processes involve multiple links, complex process flow, and large equipment investment.

Breakthrough of new process:Aiming at the pain points of traditional processes, our lithium battery recycling line with a black mass recovery rate of more than 97% adopts a fully automatic physical recycling process, achieving the following breakthroughs:

• Efficient crushing and sorting: Multi-stage crushing and refined sorting technology are used to achieve accurate separation of battery components and improve the black mass recovery rate.
• Environmentally friendly and pollution-free: The entire recycling process does not require the use of chemical reagents, and there is no wastewater or exhaust gas emissions, achieving green and environmentally friendly recycling.
• High degree of automation: The use of an automated control system realizes the automation of the entire process from battery loading to black mass collection, improving production efficiency.
