The disassembly and sorting are necessary pretreatment technologies for recycling the lithium ion battery. Wherein, shredding process and crushing process are the indispensable step in the sorting process is disassembled to waste lithium cell. At present, the shredding device and the crushing device are in two separate cavities, connected by a track. And conveying the shredded products of the lithium battery to a crusher through a crawler belt for secondary crushing, and stripping the anode powder and the cathode powder from the degummed anode current collector and cathode current collector. However, the method occupies too large space, and greatly reduces the recovery efficiency of the lithium battery. Meanwhile, the batteries are rich in complementary energy and are extremely easy to ignite and explode in the crushing process, so that the waste lithium batteries need to be prevented from igniting and exploding in the disassembling and sorting process. Currently, the discharge methods of the waste lithium ion batteries are mainly divided into physical discharge methods and chemical discharge methods. The physical discharge method consumes residual electric quantity through an external circuit, and is difficult to be applied in a large scale; the chemical discharge method discharges through brine soaking, but easily causes electrolyte leakage and generates sewage, and the recovery cost of the lithium battery is greatly improved. Therefore, the charged recovery of the waste lithium battery is an urgent technical problem to be solved.
