Obtaining recycled value from waste lithium batteries and realizing the utilization of metal resources
Research on the recycling of waste lithium batteries mainly focuses on the recovery of valuable positive electrode precious metals cobalt and lithium, and there are few reports on the separation and recovery of negative electrode materials. Therefore, by recycling waste lithium batteries, valuable metals such as nickel, cobalt, and lithium can be extracted and recycled. Lithium battery resource processing equipment Lithium battery waste is transported to the crusher for crushing, and is crushed to 3cm; the material crushed by the crusher is first transported to the airflow sorting screen, and the diaphragm paper fragments are separated by the airflow sorting screen. Since the diaphragm paper fragments are lighter, they are sucked away to the collector one by the induced draft fan with the airflow, and the material after the diaphragm paper fragments are separated is transported to the crusher, and the crusher crushes the waste to mesh; the material crushed by the crusher is transported to the analyzer, and the analyzer performs air separation on the crushed material to sort out graphite powder, lithium cobalt oxide mixed powder and metal waste; the sorted graphite powder and lithium cobalt oxide mixed powder are transported to the collector two by the induced...
