A recovery device for positive and negative electrode materials of lithium-ion batteries

Abstract

The invention discloses a recovery device for cathode and anode materials of a lithium ion battery. The structure of the recovery device comprises a motor bottom case groove, a polar plate winding drum, a grinding roller, a clamping shaft frame, a beam plate, a side ring slot vertical plate, a drawer plate cut-off cabinet and a heat exchange bottom groove. The recovery device achieves that the polar plate winding drum and the drawer plate cut-off cabinet are matched to pull out the cathode and anode material rolled plates of the lithium ion battery, the stretched surface enters the polar platewinding drum and the upper and lower sliding surfaces of the grinding roller to press and rotate a surface-grinding cleaning block layer, the effects of eliminating and cleaning the thickness of an upper additive and a lower additive and sweeping powder particles on the surface of an iron-copper incineration plate are formed, a cathode and anode material plate recycling and outputting effect is formed, and after the cathode and anode material plates of the battery are pulled out, the splitting hydrolysis operation of the lithium battery is supported, the free state of organic matters with chemical properties can be decomposed and ionized, the cathode and anode plates of the lithium ion battery taken out from a terminal can be forged, remelted and deformed, the recycling utilization rate is high, the pollution degree of the battery is low, and the environment-friendly treatment is achieved.

Description

technical field [0001] The invention relates to a recovery device for positive and negative electrode materials of lithium ion batteries, which belongs to the field of recovery of lithium batteries. Background technique [0002] Lithium battery is a battery of non-aqueous electrolyte solution. In the era when electric motorcycles and electric vehicles are popular, lithium batteries have become mainstream consumables and spare parts. After use, lithium batteries contain a lot of heavy metals and waste strong acids. It is easy to affect land fertility and air quality pollution. The disadvantages of the current technology to be optimized are: [0003] Substances that integrate organic chemistry and inorganic chemistry will be attached to the positive and negative electrode material plates of lithium-ion batteries, and the degradation efficiency of inorganic compounds is high, but organic iron and copper need to be incinerated at high temperature, and then sieved to remove iron ...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a recovery device for positive and negative materials of lithium ion batteries, to solve the problem of the adhesion of substances integrating organic chemistry and inorganic chemistry on the positive and negative materials of lithium ion batteries. , and the degradation efficiency of inorganic composites is high, but organic iron and copper need to be incinerated at high temperature, and then the iron and copper powder are screened out and continuously heated and dissolved in acid. The work of protective clothing will also be burned by local corrosion, which will affect the safety of work. Then, due to the bonding additives of the conductive coating, it will take a short time to consume and shave the bonding impurities in the recycling operation of the positive and negative plates, resulting in recycling The effect is low, resulting in a high doping degree of the coating water agent and oily organic solvent in the current collecting operation, and the problem of low power distribution and recycling rate
