Description

Technical Field

[0001] The present invention relates to a crushing and recycling device, in particular to a crushing and recycling device for lithium ion battery positive electrode current collectors based on a multi-electrode array, belonging to the technical field of ion batteries. Background Art

[0002] Lithium-ion batteries have outstanding advantages such as high energy density, support for cyclic charge and discharge, low self-discharge rate, and no memory effect. They are currently the most important type of power battery for electric vehicles. However, lithium-ion batteries can generally only be charged and discharged 500 to 1,000 times in a cycle, and their service life is relatively short. With the rapid increase in the number of electric vehicles, the number of retired lithium-ion batteries will also increase exponentially. The large-scale retirement of lithium-ion batteries will bring tremendous pressure to the subsequent treatment of their positive electrode collectors. For this reason, some scholars have proposed the use of various physical and chemical methods to achieve the crushing and recycling of lithium-ion battery positive electrode collectors.

[0003] However, due to the defects of traditional organic solvent method, alkaline solution dissolution method, thermal decomposition method, etc., some scholars have proposed to use pulse discharge to achieve the crushing and recycling of lithium-ion battery positive electrode collector. However, the current pulse discharge method and device for crushing lithium-ion battery positive electrode collector have defects. First, the crushing efficiency is not high. A single charge-discharge cannot completely crush the lithium-ion battery positive electrode collector. It requires multiple repeated charge-discharges to completely crush it. Even with multiple repeated charge-discharges, there are still a small number of lithium-ion batteries that are not completely crushed. Secondly, the crushing and recycling device is small and can only process a small number of lithium-ion batteries at a time. Therefore, the crushing efficiency of the lithium-ion battery positive electrode collector is not high, which directly affects the recycling of retired lithium-ion batteries.

[0004] Therefore, there is an urgent need to improve the lithium-ion battery crushing and recycling device to solve the above-mentioned problems. Summary of the Invention

After colliding with the inner wall of the box, a reflected wave is generated and transmitted to the lithium-ion battery.

DETAILED DESCRIPTION

[0034] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0035] like Figure 1-Figure 7 As shown, the present embodiment provides a lithium-ion battery positive electrode collector crushing and recovery device based on a multi-electrode array, including a crushing box 1, a multi-electrode oscillation component 2 is fixedly provided inside the crushing box 1, the multi-electrode oscillation component 2 includes a negative pulse part 3 and a positive pulse part 4, a plurality of angular cathode strips 301 are fixedly provided on the negative pulse part 3, and a plurality of angular anode strips 401 are fixedly provided on the positive pulse part 4, the angular cathode strips 301 and the angular anode strips 401 are staggered, and the device adopts a multi-electrode array of the multi-electrode oscillation component 2 for pulse discharge, and the conduction discharge mode is: the three groups of angular cathode strips 301 and the three groups of angular anode strips 401 discharge each other and conduct. The angular structure of the edges of the angular cathode strips 301 and the angular anode strips 401 makes the device conduction and discharge faster, and also facilitates the generation of stronger oscillation waves to act on the water in the box, generating shock waves to act on the lithium-ion battery. The oscillation waves are generated from the intersection between the three groups of angular cathode strips 301 and the three groups of angular anode strips 401, and propagate toward the inner wall of the box. After colliding with the inner wall of the box, reflected waves are generated and transmitted to the lithium-ion battery. The lithium-ion battery is affected by the oscillation waves generated between the cathode and anode, as well as the reflected waves generated after the collision with the inner wall of the box, resulting in uneven force on the positive electrode current collector. Under the action of multi-directional shock waves, high-frequency oscillations are generated, thereby achieving the purpose of breaking;

[0036] The crushing box 1 is configured as a regular hexagon in order to ensure that the oscillation waves generated by the water reach the inner wall of the box at different times, thereby making the time and direction of the reflected waves reaching the lithium-ion battery diverse, ensuring that the lithium-ion battery is subjected to multi-directional shock waves, thereby generating high-frequency oscillations and crushing. The effect of the multi-directional shock waves also ensures that a single charge-discharge of the device is sufficient to completely crush the positive electrode current collector of the lithium-ion battery, without the need for repeated discharges.

[0037] A driving shaft 501 is rotatably provided in the middle of the negative pulse part 3 and the positive pulse part 4, and a driving motor 5 is fixedly provided at one end of the driving shaft 501.

When the driving shaft 501 rotates, the triangular cleaning rings 603 are slidably provided on the angular cathode strip 301 and the angular anode strip 401. The cleaning component 6 is used to clean impurities on the multi-electrode oscillation component 2. In the process of oscillating the lithium battery, once the lithium battery is damaged, the lithium battery is greatly A large amount of impurities will adhere to the angular cathode strip 301 or the angular anode strip 401, thereby reducing the frequency of vibration of the angular cathode strip 301 or the angular anode strip 401, thereby reducing the efficiency of crushing. After starting the drive motor 5, the drive motor 5 drives the drive shaft 501 to rotate in the forward and reverse directions. During the rotation of the drive shaft 501, the cleaning component 6 threadedly connected to the drive shaft 501 will move horizontally, so the triangular cleaning ring 603 on the cleaning component 6 can clean the impurities attached to the angular cathode strip 301 or the angular anode strip 401, ensuring that the frequency of vibration of the angular cathode strip 301 or the angular anode strip 401 is not affected, while improving the efficiency of crushing.

[0038] Further, such as Figure 2 and Figure 5 As shown, one end of the negative pulse part 3 is fixedly provided with a cathode fixing part 302, and the negative pulse part 3 is fixed to the inside of the crushing box 1 through the cathode fixing part 302, so as to improve the stability of the negative pulse part 3, and the cathode fixing part 302 is fixedly provided in the inside of the crushing box 1, and is electrically connected with a negative electrode connector 9 through the angular cathode strip 301, and the negative electrode connector 9 is fixedly provided on the outer side of the crushing box 1, and a negative electrode connecting groove 102 is provided at one end of the crushing box 1, and the negative electrode connector 9 is fixedly provided inside the negative electrode connecting groove 102, and the negative electrode connector 9 inside the negative electrode connecting groove 102 is connected to the negative pole of the circuit, and a trigger pole 13 is fixedly provided inside the negative electrode connecting groove 102 below the negative electrode connector 9, and the trigger pole 13 is electrically connected to the negative electrode connector 9.

The positive electrode connector 11 inside the positive electrode connection groove 103 is connected to the positive pole of the circuit.

[0040] like Figure 3 and Figure 4 As shown, a drive shaft groove 403 is provided inside the anode fixing member 402, a drive shaft 501 passes through the anode fixing member 402 and is fixedly connected to the output end of the drive motor 5, a drive thread 503 is fixedly provided on the drive shaft 501, the drive thread 503 is screwed together with the cleaning component 6 through a thread, the drive shaft 501 is used to push the cleaning component 6 horizontally, the cleaning component 6 includes a drive ring 601, the drive ring 601 is screwed together with the drive shaft 501 through a thread, and the drive ring 601 is fixed to the triangular cleaning ring 603 through the support arm 602 When the driving motor 5 drives the driving shaft 501 to rotate, the driving ring 601 screwed together with the driving shaft 501 moves horizontally under the action of the driving shaft 501. When the driving ring 601 moves, the triangular cleaning ring 603 is driven by the support arm 602 to move horizontally on the angular cathode strip 301 or the angular anode strip 401. Therefore, impurities on the angular cathode strip 301 or the angular anode strip 401 can be removed to prevent excessive impurities from affecting the vibration frequency of the angular cathode strip 301 or the angular anode strip 401.

[0041] The end of the driving motor 5 away from the driving motor 5 is rotatably set on the negative pulse part 3 through the bearing 504, ensuring the stability of the rotation of the driving shaft 501. The driving motor 5 is fixed on the positive connection groove 103 through the motor fixing plate 502. The driving motor 5 is fixed on the positive connection groove 103 through the motor fixing plate 502, thereby improving the stability of the driving motor 5.

A discharge door 7 is slidingly provided inside the discharge door guide groove 104. Rubber sealing gaskets 702 are fixedly provided on both sides of the discharge door 7. The rubber sealing gaskets 702 can improve the sealing between the discharge door 7 and the discharge door guide groove 104 to prevent water from flowing out. A door handle 701 is provided on the upper end of the discharge door 7. The discharge door 7 passes through the upper end of the crushing box 1 and is connected to the discharge door guide groove 104. The outer box of the device is a regular hexagonal epoxy resin with a side length of 0.8m and a height of 0.8m. The crushing box 1 has a height of 1m and can process one ton of lithium-ion batteries at a time. Its recycling efficiency is higher than that of other devices. A discharge port 101 is provided in the front of the box body. A discharge door body 7 is slidably provided in the discharge door body guide groove 104 on the discharge port 101. The discharge door body 7 is opened and the lithium battery is placed in. After the discharge door body 7 is closed, a closed container is formed in the entire crushing box 1. The crushing box 1 is set to be a regular hexagon in order to make the time for the oscillation wave generated by the water to reach the inner wall of the box inconsistent, so that the time and direction of the reflected wave reaching the lithium-ion battery are diverse, ensuring that the lithium-ion battery is subjected to multi-directional shock waves, thereby generating high-frequency oscillation and crushing.

[0043] Further, if Figure 2 and Figure 6 As shown, the upper end of the crushing box 1 is connected to a water inlet pipe 10, which is connected to the interior of the crushing box 1. After the discharging door 7 seals the crushing box 1, water is discharged into the interior of the crushing box 1 through the water inlet pipe 10 on the crushing box 1. The bottom of the crushing box 1 is connected to a drain pipe 8 connected to the interior of the crushing box 1. After the crushing is completed, the water is discharged through the drain pipe 8.

[0044] The specific process is as follows: first, open the discharge door 7, put in the lithium battery, close the discharge door 7, fill the crushing box 1 with water through the water inlet pipe 10, and after the crushing of the positive electrode collector of the lithium-ion battery is completed, release the water through the drain pipe 8, and then open the discharge door 7 to recycle the lithium-ion battery.

[0045] In addition, if Figure 1As shown, a visual window groove 105 is provided on the upper side of the crushing box 1, and the visual window groove 105 is connected to the interior of the crushing box 1. A visual window 14 is fixedly provided inside the visual window groove 105.

[0046] like Figure 7 As shown in the figure, the device comprises six modules connected in parallel to maximize the efficiency of breaking up the positive current collector of a lithium-ion battery. This multi-electrode oscillation assembly can utilize both synchronous and sequential discharge modes. Specifically, six energy storage capacitors are connected in parallel to increase discharge energy, and vacuum trigger tubes (TVSs) are used as switches for the high-voltage pulse circuit. In the synchronous discharge mode, the six TVSs (vacuum trigger tubes) conduct synchronously, discharging the six energy storage capacitors simultaneously. Under the high discharge energy, the positive current collector of the lithium-ion battery is completely broken up. In the sequential discharge mode, TVS1 conducts, discharging energy storage capacitor C1. After C1 discharges, TVS2 conducts, discharging energy storage capacitor C2. After C2 discharges, TVS3 conducts, discharging energy storage capacitor C3. This process continues until TVS6 conducts, discharging energy storage capacitor C6. Sequential discharge ensures that the lithium-ion battery is continuously exposed to the shock waves generated by the underwater pulse discharge, resulting in higher breakage efficiency. At the same time, the sequential discharge mode can also be adopted by turning on TVS1, TVS2, and TVS3, and discharging the energy storage capacitors C1, C2, and C3. After the discharge of C1, C2, and C3 is completed, TVS4, TVS5, and TVS6 are turned on, and the energy storage capacitors C4, C5, and C6 are discharged. This sequential discharge ensures that the lithium-ion battery can be continuously subjected to the shock wave generated by the pulse discharge in water, and ensures that the positive electrode current collector of the lithium-ion battery can be subjected to the strong shock wave under the action of high discharge energy, thereby achieving complete fragmentation of the positive electrode current collector of the lithium-ion battery under a single charge.
