Separation device for waste vehicle-mounted lithium power battery electrode slices and separation method

Abstract

The invention relates to a separation device for waste vehicle-mounted lithium power battery electrode slices and a separation method. The separation device comprises a thermal separation mechanism, astamping friction separation mechanism and a vibration screening mechanism which are sequentially arranged along an assembly line; after the electrode slices are subjected to heating and extrusion friction by the thermal separation mechanism, hammering and friction by the stamping friction separation mechanism, and vibration and screening by the vibration screening mechanism, electrode materialsare separated from current collector metal sheets. According to the technical scheme, through the multiple modes of thermal separation, stamping friction separation and vibration screening, separationof the coated electrode materials and the current collector metal sheets is effectively achieved, the recycling rate of the electrode materials is increased, and the defects that after smashing, mixtures are complex in component and high in separation difficulty are avoided; and while the electrode materials are obtained, the integrity of the original metal sheets is kept to the greatest extent,the recovery economical efficiency is improved, in addition, the follow-up chemical method advanced treatment technology is simplified, and secondary pollution is reduced.

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
