[0002] With the rapid popularization of electric vehicles and portable electronic devices, the use of lithium batteries has increased significantly. After the end of the life cycle of these batteries, the amount of waste lithium batteries generated also increases dramatically. The abandonment of lithium batteries not only occupies a large amount of land resources, but also can cause serious pollution to the environment, therefore, waste lithium batteries must be safely and efficiently treated and stored.

[0003] Currently, when recycling the positive electrode material of waste batteries, the batteries are first mechanically crushed and separated to obtain positive electrode sheet material, which usually includes aluminum sheets and black powder active substances adhered thereto, which are usually composed of lithium compounds, carbon materials and impurities. The aluminum sheet and the black powder thereon need to be further separated to reduce the aluminum content in the black powder. The separation method usually includes the following steps: passing the sheet material to be treated through a vibrating screen, the obtained powder is transported by airflow to a cyclone separator, then the material is transported to a pulse separator, then the material obtained in the above steps is transported by pipeline to a rotary drum heating drying cylinder, then the material from the rotary drum heating drying cylinder enters a rotary kiln, and the material is degummed in the rotary kiln, then the material is discharged from the rotary kiln and is de-magnetized by an electromagnet, then the material is controlled in particle size by an airflow mill, the obtained material is collected and weighed to improve the uniformity of the material, finally the black powder material is quantitatively stored in a storage tank, and specific materials are added for mixing to obtain a large volume of uniform material, and then the material in the storage tank enters the packaging process.
