[0002] With the popularity of new energy electric vehicles and other products using rechargeable battery technology, a large number of battery modules have gradually entered the retirement period as their service life increases, and some damaged batteries that need to be replaced often occur in the daily use of new energy vehicles. With the development of battery technology and the increasing demand for environmental protection and sustainable development in the market, the disassembly and recycling of battery modules has become an important link. It not only helps to protect the environment, but also realizes the effective use of resources.

[0003] For example, the existing Chinese patent (CN213701204U) discloses an integrated recycling and disassembly device for lithium battery modules, which comprises a disassembly workbench, a fixed sliding frame is installed above the disassembly workbench, a lifting sliding plate is installed on the surface of the fixed sliding frame, the upper end of the lifting sliding plate is connected with a driving cylinder installed at the top end of the fixed sliding frame through an extension rod, a cutting mechanism is installed on the lifting sliding plate, a cleaning tank is installed on one side of the disassembly workbench, a cleaning driving motor is installed at the upper end of the cleaning tank, a stirring rod is rotatably connected to the lower end of the cleaning driving motor through a rotating shaft, a conveying mechanism is installed on one side of the cleaning tank, a cutting driving motor is installed on the cutting mechanism, and a cutting wheel disc is rotatably connected to one end of the cutting driving motor through a rotating shaft.

The crushing treatment method can damage healthy battery monomers, and the various materials in the module are crushed and mixed together, making it difficult to distinguish and classify different materials, and further processing the crushed materials is difficult, greatly increasing the recycling difficulty.
