Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery cell recycling, and in particular to a low-carbon battery cell separator and electrode sheet separation and recycling device. BACKGROUND

[0002] With the rapid development of China's new energy vehicle industry, lithium batteries, as the main power battery for vehicles, have a service life of 3-5 years. The battery cells of waste lithium batteries contain valuable metals and toxic and harmful substances. Therefore, recycling and reusing waste lithium batteries not only realizes resource recycling, but also reduces environmental pollution.

[0003] To this end, when recycling lithium batteries, the prior art uses a method of first crushing the battery cells and then recycling them. However, in the case of complete crushing of the battery cells, the valuable components in the separator and electrode sheet are mixed together, making separation difficult. Multiple devices are required for gradual separation, resulting in a long recycling process, large equipment investment, and high energy consumption when multiple devices are in operation, which is not conducive to low-carbon environmental protection.

[0004] Another recycling method is to separately recycle the separator and electrode sheet by separating the separator and electrode sheet of the battery cell. The electrode assembly of the battery cell mainly consists of a first separator, a first electrode sheet, a second separator, and a second electrode sheet stacked together. Since the separator and electrode sheet of the battery cell are relatively soft, the device used in the prior art to recycle the separator and electrode sheet mainly uses manual separation of the separator and electrode sheet. Therefore, the efficiency of recycling the separator and electrode sheet in the battery cell is low, and it is not conducive to automation. SUMMARY

[0005] The purpose of the present application is to provide a low-carbon battery cell separator and electrode sheet separation and recycling device to realize the automatic separation and recycling of the separator and electrode sheet of the battery cell, improve the recycling efficiency, and make the recycling process low-carbon and environmentally friendly.

[0006] To solve the above technical problems, the present application provides the following technical solutions:

[0007] The application discloses a low-carbon cell diaphragm pole piece separation and recovery device which is used for separating and recovering a first diaphragm, a first pole piece, a second diaphragm and a second pole piece of an electrode assembly, and comprises a traction member, a cutting member, two tearing mechanisms and four recovery mechanisms. The cutting member is used for cutting the first diaphragm. The two tearing mechanisms are used for tearing the first pole piece and the second pole piece respectively. The four recovery mechanisms are used for recovering the first diaphragm, the first pole piece, the second diaphragm and the second pole piece respectively. In a first direction, the cutting member, one of the recovery mechanisms, one of the tearing mechanisms, another of the recovery mechanisms, another of the tearing mechanisms and the rest of the recovery mechanisms are sequentially and spacedly arranged. The traction member is used for pulling the electrode assembly to move in the first direction and sequentially pass through the cutting member, one of the recovery mechanisms, one of the tearing mechanisms, another of the recovery mechanisms, another of the tearing mechanisms and the rest of the recovery mechanisms.

[0008] In an embodiment, the tearing mechanism comprises a clamping assembly, a supporting member, a rotating tearing disc and a first driving member. The clamping assembly is used for clamping the electrode assembly. The rotating tearing disc and the supporting member are arranged opposite to each other. The traction member is used for driving the electrode assembly to pass between the rotating tearing disc and the supporting member. The distance between the rotating tearing disc and the supporting member is adjustable. The first driving member is used for driving the rotating tearing disc to rotate.

[0009] In an embodiment, the rotating tearing disc comprises a disc body and a frosted layer. The frosted layer is arranged on a side of the disc body which is opposite to the supporting member.

[0010] In an embodiment, the rotating tearing disc comprises a disc body and a suction disc. The suction disc is arranged on a side of the disc body which is opposite to the supporting member.

[0011] In an embodiment, the recovery mechanism comprises a scraper and a recovery box. The scraper is inclined towards the electrode assembly, and the front end of the scraper is close to the electrode assembly. The recovery box is adjacent to the rear end of the scraper to collect the pole pieces and diaphragms scraped from the electrode assembly by the scraper.

[0012] In an embodiment, the front end of the scraper is provided with an arc surface part opposite to a side of the electrode assembly. The front end of the scraper extends in a direction opposite to the first direction to form a thorn part.

[0013] In an embodiment, the recovery mechanism comprises a housing, a negative pressure device, a recovery roller and a second driving member. The housing is provided with a first opening and a second opening. The negative pressure device is connected to the first opening. The second opening is towards and close to the electrode assembly. The recovery roller is arranged in the housing and can rotate relative to the housing. The second driving member is used for driving the recovery roller to rotate.

[0014] In one embodiment, the outer surface of the recycling roller is provided with an adhesive layer.

[0015] In one embodiment, the second opening of the housing is funnel-shaped.

[0016] In one embodiment, a tensioning assembly is further included, the tensioning assembly comprising two spaced-apart tensioning rollers, the traction member being used to drive the electrode assembly to sequentially pass around the two tensioning rollers and then sequentially pass along a first direction through the cutting member, one of the recycling mechanisms, one of the tearing mechanisms, another recycling mechanism, another tearing mechanism, and the remaining recycling mechanisms.

[0017] Compared with existing technologies, the low-carbon battery cell separator electrode separation and recycling device described in this embodiment has the following advantages:

[0018] In this paper, the traction member pulls the electrode assembly along a first direction and sequentially passes through the cutting member, one of the recycling mechanisms, one of the tearing mechanisms, another recycling mechanism, another tearing mechanism, and the remaining recycling mechanisms. When the electrode assembly passes through the cutting member, the cutting member first cuts the first diaphragm. Then, when the electrode assembly passes through one of the recycling mechanisms, the recycling mechanism can recycle the first diaphragm and expose the first electrode. Next, when the electrode assembly passes through one of the tearing mechanisms, the tearing mechanism can tear the first electrode. Then, when the electrode assembly passes through another recycling mechanism, the recycling mechanism can recycle the first electrode. Furthermore, after the electrode assembly passes through another tearing mechanism, the tearing mechanism tears the second electrode. Finally, the remaining two recycling mechanisms are used to recycle the second electrode and the second diaphragm. Therefore, this paper can automatically separate and recycle the first diaphragm, the first electrode, the second diaphragm, and the second electrode, realizing automated recycling of the diaphragm and electrode of the battery cell, reducing manual intervention, and improving recycling efficiency. In addition, compared to recycling by crushing battery cells, the battery cell recycling method described in this article is more low-carbon and environmentally friendly. Attached Figure Description

Detailed Implementation

[0029] The specific implementation methods described herein will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate this document, but are not intended to limit the scope of this document.

[0030] like Figure 1As shown, this article relates to a low-carbon battery cell separator and electrode separation and recycling device, used to separate and recycle the first separator 110, the first electrode 120, the second separator 130, and the second electrode 140 of the electrode assembly 100. It includes a traction member 1, a cutting member 2, a tearing mechanism 3, and a recycling mechanism 4. The cutting member 2 is used to break the first separator 110. Two tearing mechanisms 3 are provided to correspondingly tear the first electrode 120 and the second electrode 140. Four recycling mechanisms 4 are provided to correspondingly recycle the first separator 110, the first electrode 120, and the second electrode 140. The first electrode 120, the second diaphragm 130, and the second electrode 140; along the first direction, the cutting member 2, one of the recycling mechanisms 4, one of the tearing mechanisms 3, another recycling mechanism 4, another tearing mechanism 3, and the remaining recycling mechanisms 4 are arranged sequentially at intervals, and the traction member 1 is used to pull the electrode assembly 100 to move along the first direction and pass sequentially through the cutting member 2, one of the recycling mechanisms 4, one of the tearing mechanisms 3, another recycling mechanism 4, another tearing mechanism 3, and the remaining recycling mechanisms 4.

[0031] In the text, the traction member 1 pulls the electrode assembly 100 to move along a first direction and sequentially passes through the cutting member 2, one of the recovery mechanisms 4, one of the tearing mechanisms 3, another recovery mechanism 4, another tearing mechanism 3, and the remaining recovery mechanisms 4. When the electrode assembly 100 passes through the cutting member 2, the cutting member 2 first cuts the first diaphragm 110, and then the traction member 1 pulls the uncut first electrode 120, second diaphragm 130, and second electrode 140 to move in the first direction. When the electrode assembly 100 passes through one of the recovery mechanisms 4, the recovery mechanism 4 can recover the first diaphragm 110 and expose the first electrode 120. When the electrode assembly 100 continues to move and passes through one of the tearing mechanisms 3, the tearing mechanism 3... The first electrode 120 is torn open. At this time, the traction member 1 pulls the unbroken second diaphragm 130 and the second electrode 140 in the first direction. When the electrode assembly 100 continues to move and passes through another recycling mechanism 4, the recycling mechanism 4 recycles the first electrode 120. Then, after the electrode assembly 100 continues to move and passes through another tearing mechanism 3, the tearing mechanism 3 tears open the second electrode 140. Finally, the second electrode 140 and the second diaphragm 130 are recycled through the remaining two recycling mechanisms 4. Therefore, this method can automatically separate and recycle the first diaphragm 110, the first electrode 120, the second diaphragm 130, and the second electrode 140, realizing automated recycling of the separator and electrode of the battery cell, reducing manual intervention, and improving recycling efficiency. In addition, compared with the method of recycling by crushing the battery cell, the battery cell recycling method described in this paper is more low-carbon and environmentally friendly.

[0032] The tearing mechanism 3 includes a clamping assembly 31, a support member 32, a rotating tearing disc 33, and a first driving member. The clamping assembly 31 is used to clamp the electrode assembly 100. The rotating tearing disc 33 and the support member 32 are arranged opposite to each other. The traction member 1 is used to drive the electrode assembly 100 to pass between the rotating tearing disc 33 and the support member 32. The distance between the rotating tearing disc 33 and the support member 32 is adjustable. The first driving member is used to drive the rotating tearing disc 33 to rotate.

[0033] Specifically, when the traction member 1 passes the tearing mechanism 3, the clamping assembly 31 first clamps the electrode assembly 100. At this time, the tearing mechanism 3 is located between the clamping assembly 31 and the traction member 1, so that the electrode assembly 100 will not shift when the rotating tearing disc 33 tears the electrode sheet, ensuring stable tearing of the electrode sheet. The specific principle of the rotating tearing disc 33 tearing the electrode sheet is that the rotating tearing disc 33 and the bearing member 32 are first driven to move closer to each other so as to clamp the electrode assembly 100 together. Then, the first driving member drives the rotating tearing disc 33 to rotate 90°-180° to tear the electrode sheet to break.

[0034] Both the rotating tearing disc 33 and the supporting member 32 are made of materials with high hardness, which can increase the positive pressure when the rotating tearing disc 33 and the supporting member 32 clamp the electrode assembly 100, increase the friction between the rotating tearing disc 33 and the electrode assembly 100, and improve the efficiency and success rate of the rotating tearing disc 33 in tearing the electrode sheet.

[0035] The clamping assembly 31 includes a first clamping block 311, a second clamping block 312, and a clamping drive. The first clamping block 311 and the second clamping block 312 are directly opposite each other. The clamping drive drives the first clamping block 311 and the second clamping block 312 to move closer or further apart, thereby clamping the electrode assembly 100. The clamping drive can be a clamping cylinder. The first clamping block 311 and the second clamping block 312 are fixedly connected to the two output ends of the clamping cylinder, thereby facilitating the adjustment of the distance between the first clamping block 311 and the second clamping block 312.

[0036] Combination Figure 2 and Figure 3 As shown, in one embodiment, the rotating tearing disc 33 includes a disc body 331 and a frosted layer 332. The frosted layer 332 is disposed on the side of the disc body 331 facing the support member 32, thereby increasing the friction with the electrode and improving the efficiency and success rate of tearing the electrode.

[0037] Specifically, in one embodiment, the frosted layer 332 is a single frosted block that completely covers the side of the disc 331 facing the support member 32, thereby increasing the contact area between the electrode and the frosted layer 332. In another embodiment, the frosted layer 332 comprises multiple frosted blocks arranged in a ring array on the side of the disc 331 facing the support member 32, thereby reducing the contact area between the frosted layer 332 and the electrode, while increasing the pressure per unit area between the frosted layer 332 and the electrode, which is more conducive to tearing the electrode.

[0038] Combination Figure 4 to Figure 6 As shown, in another embodiment, the rotating tearing disc 33 includes a disc body 331 and a suction cup 333. The suction cup 333 is located on the side of the disc body 331 facing the support member 32, so that the suction cup 333 can hold the outer surface of the electrode sheet and then tear the electrode sheet when the suction cup 333 rotates.

[0039] Specifically, in one embodiment, a suction cup 333 is provided, and the outer periphery of the suction cup 333 extends to the outer periphery of the disc body 331, thereby generating greater suction force to improve the efficiency of tearing the electrode sheet. Further, the diameter of the suction cup 333 is less than or equal to the width of the electrode sheet to ensure that the suction cup 333 does not leak air and can stably hold the electrode sheet. In this embodiment, the suction cup 333 can be either a concave suction cup 333 or a convex suction cup 333. In another embodiment, multiple suction cups 333 are provided, and the multiple suction cups 333 are arranged in a circular array on the side of the disc body 331 facing the support member 32 to reduce the contact area between the suction cup 333 and the electrode sheet, increasing the pressure per unit area between the suction cup 333 and the electrode sheet, which is beneficial for tearing the electrode sheet. In this embodiment, the suction cup 333 can also be either a concave suction cup 333 or a convex suction cup 333.

[0040] Combination Figure 7 and Figure 8 As shown, in one embodiment, the recycling mechanism 4 includes a scraper 41 and a recycling bin 42. The scraper 41 is inclined toward the electrode assembly 100, and the front end of the scraper 41 is close to the electrode assembly 100. The recycling bin 42 is adjacent to the rear end of the scraper 41 to collect the electrode sheets and diaphragms scraped off the electrode assembly 100 by the scraper 41.

[0041] With the scraper 41 and the recycling bin 42 in place, and the scraper 41 close to the electrode assembly 100, when the traction member 1 drives the electrode assembly 100 through the recycling mechanism 4, the scraper 41 picks up the broken electrode sheet and diaphragm, allowing the electrode sheet and diaphragm to move along the scraper 41 from the front end to the rear end and fall into the recycling bin 42, thereby achieving automatic separation and collection of the electrode sheet and diaphragm.

[0042] Optionally, the front end of the scraper 41 has an arc-shaped portion 411 on the side facing the electrode assembly 100, thereby preventing the scraper 41 from scratching the electrode assembly 100 and avoiding interference with the movement of the electrode assembly 100 along the first direction. The front end of the scraper 41 extends in the opposite direction to the first direction and forms a spike 412. Thus, during the movement of the electrode assembly 100 along the first direction, the ends of the cut electrode plates and diaphragms on the electrode assembly 100 can be lifted by the spikes 412, thereby achieving the separation of the electrode plates and diaphragms on the electrode assembly 100.

[0043] Combination Figure 9 As shown, in another embodiment, the recycling mechanism 4 includes a housing 43, a negative pressure device 44, a recycling roller 45, and a second driving member. The housing 43 has a first opening 431 and a second opening 432. The negative pressure device 44 is connected to the first opening 431. The second opening 432 faces and is close to the electrode assembly 100. The recycling roller 45 is disposed inside the housing 43 and can rotate relative to the housing 43. The second driving member is used to drive the recycling roller 45 to rotate.

[0044] When the recycling mechanism 4 is running, the negative pressure device 44 operates, creating a negative pressure inside the housing 43, thereby generating suction at the second opening 432. Since the second opening 432 of the housing 43 is close to the electrode assembly 100, the disconnected electrode plates and diaphragms on the electrode assembly 100 can be sucked into the housing 43 when passing through the recycling mechanism 4. At the same time, since the second driving member drives the recycling roller 45 to rotate, the electrode plates and diaphragms that have entered the housing 43 can be wound around the recycling roller 45. This facilitates the recycling of the electrode plates and diaphragms and prevents them from being sucked to the negative pressure device 44, thus affecting the normal operation of the negative pressure device 44.

[0045] Optionally, the outer surface of the recovery roller 45 is coated with an adhesive to form an adhesive layer on the outer surface of the recovery roller 45, so that the ends of the electrode and diaphragm entering the housing 43 can be bonded to the winding roller, thereby making it easier and better for the winding roller to wind the electrode and diaphragm onto it.

[0046] Furthermore, the second opening 432 of the housing 43 is funnel-shaped, which facilitates the smoother intake of the electrode and diaphragm into the housing, thereby improving the recovery efficiency of the electrode or diaphragm.

[0047] Combination Figure 1 As shown, in this embodiment, the cutting element 2 is a laser cutter. When the electrode assembly 100 passes through the laser cutter, the temperature of the laser cutter is set to cut off the outermost first diaphragm 110 of the electrode assembly 100. Compared with cutting with a knife, saw blade or grinding disc, cutting with a laser cutter will not damage the electrode sheet of the next layer, thereby ensuring that the traction element 1 continues to smoothly pull the electrode assembly 100 to move along the first direction.

[0048] In this embodiment, the traction member 1 is specifically a traction clamp, which can clamp the free end of the electrode assembly 100, and then allow the electrode assembly 100 to unfold and move stably along the first direction, so as to sequentially separate and recycle the diaphragm and electrode on the electrode assembly 100.

[0049] In this embodiment, the low-carbon battery cell separator electrode separation and recycling device further includes a tensioning component 5. The tensioning component 5 includes two tensioning rollers 51 spaced apart. The traction member 1 is used to drive the electrode assembly 100 to pass sequentially around the two tensioning rollers 51 and then sequentially pass along the first direction through the cutting member 2, one of the recycling mechanisms 4, one of the tearing mechanisms 3, another recycling mechanism 4, another tearing mechanism 3, and the remaining recycling mechanisms 4.

[0050] By setting the tensioning component 5, the electrode assembly 100 can be kept taut in the first direction after the traction member 1 drives the electrode assembly 100 around the two tensioning rollers 51, thereby ensuring smoother separation and recycling of the electrode sheet and diaphragm.

[0051] The specific working process of the low-carbon battery cell separator electrode separation and recycling device described in this article is as follows:

[0052] The traction clamp first clamps the free end of the electrode assembly 100 to unfold the electrode plate and diaphragm of the electrode assembly 100. Then, the traction clamp drives the electrode assembly 100 to move along the first direction after passing around the two tension rollers 51, so that the electrode assembly 100 is in a taut state in the first direction. When the electrode assembly 100 passes the laser cutter, the laser cutter cuts the first diaphragm 110. Then, the electrode assembly 100 moves to one of its recycling mechanisms 4 to recycle the cut first diaphragm 110. Next, the electrode assembly 100 moves to one of its tearing mechanisms 3, where it is pressed by the rotating tearing disc 33 and the bearing member 32. The electrode assembly 100 is tightened, and the rotating tearing disc 33 is rotated to tear the first electrode 120. Then, the electrode assembly 100 continues to move to another recycling mechanism 4, which recycles the first electrode 120. Then, the electrode assembly 100 continues to move to another tearing mechanism 3, where the second electrode 140 is torn apart under the action of the rotating tearing disc 33. Finally, the traction clamp releases the remaining second diaphragm 130, allowing the second electrode 140 and the second diaphragm 130 to be recycled by the other two recycling mechanisms 4, thus completing the separation and recycling of the cell diaphragm and electrode.

[0053] In summary, compared with existing technologies, the low-carbon battery cell separator electrode separation and recycling device proposed in this paper can automatically separate and recycle the electrode and separator without the need for subsequent separation, thereby improving the efficiency of battery cell recycling. At the same time, the relatively simple structure of this paper can reduce the cost of the equipment and has high practicality.

[0054] The above description is only an optional implementation method of this article. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this article, and these improvements and substitutions should also be considered within the scope of protection of this article.
