Lithium-ion battery materials mainly consist of cathode materials, anode materials, separators, electrolyte, aluminum foil, copper foil and binders.Among them, cathode materials account for approximately 33% of the total cost, and anode materials account for 10%; electrolyte and separators make up around 12% and 30% of the cost respectively. Cobalt and lithium, the key metals to be recovered from lithium-ion batteries, are primarily concentrated in cathode materials containing cobalt and lithium.
The recovery and treatment of waste lithium-ion batteries and their scraps can not only ease the shortage of cobalt, lithium and other resources and protect the ecological environment, but also serve as an effective way to conserve resources.Aluminum foil and copper foil used as current collectors for cathodes and anodes also possess high recovery value.
This utility model relates to the field of waste battery treatment, in particular to a new type of lithium battery processing equipment.The system comprises a shredder, crusher, magnetic separator, pulverizer, classifier, sorting equipment, diverter valve, Collector I, Collector II, Collector III, Pulse Dust Collector I, Pulse Dust Collector II, Pulse Dust Collector III, High-pressure Fan I, High-pressure Fan II, High-pressure Fan III, Air Classifier I, Air Classifier II, Air Classifier III, Induced Draft Fan I and Induced Draft Fan II.
The shredder is sequentially connected with the crusher, magnetic separator, pulverizer, classifier, sorting equipment, diverter valve, Collector I, Pulse Dust Collector I and High-pressure Fan II.
This treatment system features rational structural design. It can produce powder materials of high purity during lithium battery crushing and recovery, with low pollution and high efficiency. The treatment process has simple and well-designed procedures, causes minor environmental pollution in operation, achieves high recovery rate and boasts strong practicability.
