A separation device and separation method for electrode sheets of waste vehicle-mounted lithium power batteries

Abstract

The invention relates to a separation device and separation method for electrode sheets of waste vehicle-mounted lithium power batteries. The heating and extrusion friction, the hammering and friction of the stamping friction separation mechanism, and the vibration screening of the vibration screening mechanism form the separation of the electrode material and the metal sheet of the current collector. It can be seen from the above technical scheme that the present invention effectively realizes the separation of the coated electrode material and the current collector metal sheet through thermal separation, stamping friction separation and vibratory screening, improves the recycling rate of the electrode material, and avoids crushing The composition of the final mixture is complicated and the separation is difficult; while the electrode material is obtained, the integrity of the original metal sheet is maintained to the greatest extent, the economy of recycling is improved, and the subsequent chemical advanced treatment process is simplified, reducing Secondary pollution.

Description

technical field [0001] The invention relates to the field of recycling waste batteries, in particular to a separation device and separation method for electrode sheets of waste vehicle-mounted lithium power batteries. Background technique [0002] With the rapid development of the new energy automobile industry, a large number of used vehicle lithium power batteries are scrapped, which will inevitably cause a huge waste of resources and serious pollution of the environment. Therefore, from the aspects of cost reduction, environmental protection and resource utilization improvement, the recycling of waste vehicle lithium power batteries is of great significance for the sustainable development of my country's new energy electric vehicle industry. [0003] At present, there are physical and chemical methods for recycling waste vehicle lithium power batteries. The physical recovery process uses manual or mechanical dismantling as pretreatment, crushes the waste electrodes, and ...

AI Technical Summary

Problems solved by technology

The physical recovery process uses manual or mechanical dismantling as pretreatment, crushes the waste electrodes, and then uses different sorting methods to achieve material separation and resource recovery. For example, the commonly used crushing and screening method is to crush the waste electrodes together. Then the mixture is physically screened and separated. The process is simple and easy, and there is no secondary pollution, but the separation effect is poor, the recovery rate is low, there are too many impurities, and the application value is not high.

The chemical method can effectively recycle waste vehicle lithium power batteries and obtain high-value materials, but the process is more complicated, the cost is higher, the technical difficulty is too high, the toxic by-products of the reaction are difficult to control, and the environment is seriously polluted
