Description

Technical Field

[0001] The utility model relates to the technical field of waste lithium battery treatment, in particular to a novel integrated shredder. Background Art

[0002] Lithium battery recycling technology is mainly divided into waste lithium iron phosphate battery recycling technology, waste lithium cobalt oxide battery recycling technology, waste ternary battery recycling technology, etc. Waste lithium battery recycling technology uses waste lithium batteries as raw materials and prepares a mixed solution containing positive and negative electrode materials through processes such as discharge, disassembly and crushing, alkaline solution soaking, and impurity removal. The mixed solution is then filtered and separated into positive and negative electrode materials by a filtration and precipitation system, and then the materials are cleaned, dried, dried, and packaged for recycling. After the copper foil and aluminum foil are separated from the positive and negative electrode materials, they are washed, drained, recycled, sorted, packaged, and the solution is recycled. This technical system improves the resource recovery rate and reduces the cost of three waste treatment. In the lithium battery recycling process, it is still manually cut into blocks, and then immersed in different solutions. The lithium battery reacts with the solution to cause the positive and negative electrode materials to be peeled off from the block lithium battery, and then filtered, separated, cleaned, dried, and recycled.
