[0002] Lithium-ion batteries (LIBs) are widely used due to their high voltage and high energy density. Among them, lithium iron phosphate (LiFePO4 or LFP) is widely used in electric vehicles due to its high theoretical capacity (170mAh / g), low cost, environmental friendliness, safety, and thermal stability. However, the lifespan of lithium-ion batteries is quite limited. The lifespan of these electric vehicle power batteries is generally 5 to 10 years. With the rapid development of electric vehicles, a large number of lithium batteries will be scrapped in the next few years, and the recycling and harmless disposal of these failed batteries has become a topic of concern.
[0003] The recycling process for used batteries mainly includes two steps: pretreatment and recovery of valuable metals. Pretreatment primarily involves discharging, disassembly, crushing, and separation of active materials from current collectors. Currently, the discharge methods for used batteries are typically direct physical discharge, puncture discharge, and chemical discharge. In a certain number of cells, this energy is essentially wasted.

[0035] The following describes in detail the overall structure, working principle, and technical effects of the fast discharge device 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.
[0036] Please refer to Figures 1-2 The fast discharge device 010 provided by this utility model is used for the recovery and utilization of residual electricity in various types of waste battery cells.
[0037] Among them, the waste battery cells can be square aluminum shell cells of different models, square aluminum shell cells with the positive and negative terminals on the same side, and square aluminum shell cells with the positive and negative terminals on both sides.
[0038] This utility model proposes a fast discharge device 010, comprising:
[0039] The body 100 is provided with at least one clamp 200, which is used to clamp the battery cell.
[0040] The first discharge assembly 300 has two spaced-apart first needle beds 310. The first discharge assembly 300 is located on the top of the clamp 200 and is slidably disposed with the body 100 so that the first discharge assembly 300 drives the two first needle beds 310 to move relative to the clamp 200 along the Z-axis direction.
[0041] The second discharge assembly 400 is disposed on the body 100. The second discharge assembly 400 is disposed on both sides of the clamp 200. The second discharge assembly 400 is provided with a second needle bed 410.
[0042] Understandably, when discharging discarded battery cells, for square aluminum-cased cells with positive and negative terminals on the same side, the first discharge assembly 300 can be moved to discharge the cells using two first needle beds 310. For square aluminum-cased cells with positive and negative terminals on opposite sides, the second discharge assembly 400 located on both sides of the clamp 200 can be moved simultaneously to discharge the cells using a second needle bed 410. By setting the first discharge assembly 300, the fast discharge device 010 can discharge square cells with positive and negative terminals on the same side and of various lengths and widths. By setting the second discharge assembly 400, the fast discharge device 010 can discharge square cells with positive and negative terminals on opposite sides and of various lengths and widths. This fast discharge device 010 is compatible with different models of square aluminum-cased cells, can be quickly adjusted according to different models of square aluminum-cased cells, is simple to operate, and each unit is independent and does not conflict with each other, resulting in high device utilization.
[0043] In this embodiment, the fast discharge device 010 has an X-axis direction, a Y-axis direction, and a Z-axis direction, which are based on a spatial rectangular coordinate system.
[0044] In this embodiment, the fast discharge device 010 includes a body 100.
[0045] In this embodiment, please refer to Figures 1-2 The main body 100 includes an operating table 110 and a base cabinet 120. The operating table 110 is located on the top of the base cabinet 120. The top surface of the operating table 110 is used to install fixtures 200, first discharge assembly 300 and second discharge assembly 400, etc.
[0046] In this embodiment, the fast discharge device 010 includes a clamp 200.
[0047] The main body 100 is provided with at least one clamp 200, which is used to clamp the battery cell.
[0048] In this embodiment, please refer to Figure 2 The clamp 200 includes a first clamping plate 210 and a second clamping plate 220 symmetrically arranged. The first clamping plate 210 and the second clamping plate 220 are movably arranged on the operating table 110 of the main body 100. A clamping member 230 is provided on the back side of the first clamping plate 210 and the second clamping plate 220. The clamping member 230 pushes the first clamping plate 210 and the second clamping plate 220 along the Y-axis direction so that the first clamping plate 210 and the second clamping plate 220 clamp the battery cell.
[0049] It is understandable that by simultaneously adjusting the clamping members 230 on the back side of the first clamping plate 210 and the second clamping plate 220, the first clamping plate 210 and the second clamping plate 220 are moved towards the center, thereby clamping the battery cell with the first clamping plate 210 and the second clamping plate 220. The clamp 200 configured in this way can be adapted to battery cells of different thicknesses.
[0050] Alternatively, please refer to Figure 2 The clamping member 230 includes a support rod 231 and a push rod 232. The support rod 231 is mounted on the operating table 110. The support rod 231 has a threaded hole, and the push rod 232 is threadedly connected to the threaded hole so that the push rod 232 pushes the first clamping plate 210 or the second clamping plate 220.
[0051] It is understood that the push rod 232 is provided with a thread that mates with the threaded hole. When the push rod 232 is rotated, the push rod 232 moves along the threaded hole toward the first clamping plate 210 or the second clamping plate 220 and pushes the first clamping plate 210 or the second clamping plate 220, thereby realizing the process of the clamping member 230 pushing the first clamping plate 210 or the second clamping plate 220.

Specifically, for a square battery cell with positive and negative terminals located on both sides, the square battery cell is placed on the clamp 200 with its positive and negative terminals facing the second discharge assembly 400 on both sides, and the second discharge assembly 400 on both sides discharges on the positive and negative terminals respectively.
[0055] In this embodiment, please refer to Figures 1-2 The second needle bed 410 is slidably disposed on the second discharge assembly 400 so that the second needle bed 410 can move relative to the clamp 200 along the Z-axis. This arrangement allows for the discharge of square cells of various lengths and widths with the positive and negative terminals located on both sides.
[0056] Optionally, the second discharge assembly 400 includes a third guide rail 420, which is vertically disposed on the body 100, and the second needle bed 410 is slidably disposed on the third guide rail 420.
[0057] Understandably, the second needle bed 410 moves relative to the clamp 200 along the Z-axis, allowing it to discharge square cells with positive and negative terminals located on opposite sides at different positions. Specifically, moving the second needle bed 410 up and down along the third guide rail 420 allows it to move relative to the clamp 200 along the Z-axis.
[0058] Optionally, the second needle bed 410 is detachably connected to the third guide rail 420, and the second needle bed 410 includes transverse needle beds of different lengths.
[0059] Understandably, this setup allows for the selection of different lengths of transverse needle beds based on the length of the battery cell, resulting in a higher compatibility with square battery cells where the positive and negative terminals are located on both sides.
[0060] In this embodiment, the fast discharge device 010 includes a first discharge component 300.
[0061] The first discharge assembly 300 is provided with two spaced first needle beds 310. The first discharge assembly 300 is located on the top of the clamp 200 and is slidably disposed with the body 100 so that the first discharge assembly 300 drives the two first needle beds 310 to move relative to the clamp 200 along the Z-axis direction.
[0062] Understandably, for a square battery cell with the positive and negative terminals on the same side, the square battery cell is placed on the rack fixture 200 with its positive and negative terminals facing upwards, and the first discharge assembly 300 is moved so that the two first needle beds 310 are aligned with the positive and negative terminals to discharge it.
[0063] In this embodiment, please refer to Figures 1-2 The body 100 is provided with at least one first guide rail 320, which is vertically arranged and located on one side of the clamp 200. The first discharge component 300 is slidably arranged on the at least one first guide rail 320 so that the first discharge component 300 drives the two first needle beds 310 to move relative to the clamp 200 along the Z-axis direction.
[0064] The main body 100 has at least one first support plate 321 vertically arranged on the operating table 110, and a first guide rail 320 is vertically arranged on the first support plate 321.
[0065] Understandably, based on the length of the battery cell clamped on the fixture 200, the position of the first discharge component 300 on the first guide rail 320 can be adjusted so that the first discharge component 300 drives the two first needle beds 310 to move relative to the fixture 200 along the Z-axis, so that the two first needle beds 310 can discharge the battery cell.
[0066] Alternatively, please refer to Figure 1 When there are at least two first guide rails 320 and first support plates 321, the at least two first guide rails 320 and first support plates 321 are spaced apart, and at least one transverse support plate 322 is connected between adjacent first support plates 321. The transverse support plate 322 supports the first support plates 321 on both sides and can limit the position of the first support plates 321.
[0067] In this embodiment, two first needle beds 310 are slidably disposed on the first discharge assembly 300 so that the first discharge assembly 300 moves relative to the battery cell along the X-axis direction.
[0068] Alternatively, please refer to Figure 1 The first discharge assembly 300 includes a second guide rail 330, which is slidably disposed with the body 100 so that the second guide rail 330 and the first needle bed 310 move relative to the clamp 200 along the Z-axis direction; the second guide rail 330 is disposed along the X-axis direction, and the first needle bed 310 is slidably disposed on the second guide rail 330 so that the first discharge assembly 300 moves relative to the battery cell along the X-axis direction.
[0069] The first discharge assembly 300 also includes a second support plate 331, a second guide rail 330 is disposed on the front side of the second support plate 331, and the back side of the second support plate 331 is slidably connected to the first guide rail 320.
[0070] Understandably, based on the positions of the positive and negative terminals on the battery cell held in the clamp 200, the positions of the two first needle beds 310 on the second guide rail 330 can be adjusted so that the first discharge assembly 300 can move relative to the battery cell along the X-axis, enabling the two first needle beds 310 to discharge the battery cell.
[0071] In this embodiment, two first needle beds 310 are slidably disposed on the first discharge assembly 300 so that the two first needle beds 310 move relative to the first discharge assembly 300 along the X-axis direction.
[0072] It is understandable that, since the distance between the positive and negative terminals of different types of battery cells is different, the first discharge assembly 300 can be adapted to more types of battery cells by setting two sliding first needle beds 310.
[0073] Alternatively, please refer to Figure 1 The first discharge assembly 300 includes a slider 311, which is slidably disposed on the first discharge assembly 300. A slide rail 312 is provided on the slider 311 along the X-axis direction, and two first needle beds 310 are slidably disposed on the slide rail 312.
[0074] The back of the slider 311 is slidably mounted on the second guide rail 330 of the first discharge assembly 300, so that the slider 311 can move along the second guide rail 330 in the X-axis direction.
[0075] Understandably, the two second needle beds 410 can be adjusted according to the distance between the positive and negative terminals of the actual battery cell so that the two second needle beds 410 can discharge the battery cell.
[0076] In this embodiment, the fast discharge device 010 includes a control module 500.
[0077] Please refer to Figure 1 The control module 500 is electrically connected to the first needle bed 310 and the second needle bed 410 via wires.

[0079] In this embodiment, the fast discharge device 010 includes an energy storage module.
[0080] The energy storage module is electrically connected to the first needle bed 310 and the second needle bed 410 via wires. This configuration can fully utilize the residual electricity in the waste battery cells and charge the energy storage device through the energy storage module, which can provide energy for the recycling process of the battery positive electrode material.
[0081] In this embodiment, please refer to Figure 1 and Figure 2 The operating table 110 is equipped with eight clamps 200 and corresponding first discharge components 300 and second discharge components 400. In order to facilitate operation and meet discharge efficiency requirements, four clamps 200 and corresponding first discharge components 300 and second discharge components 400 are grouped together, with one group facing the front of the operating table 110 and the other group facing the back of the operating table 110.

Adjust the second guide rail 330 to move downwards along the first guide rail 320, while simultaneously adjusting the slider 311 and the two first needle beds 310 to the corresponding positions of the positive and negative terminals of the battery cell. Then, the operation control module 500 discharges the battery cell.
[0084] For square aluminum-cased battery cells with positive and negative terminals located on both sides, the second discharge assembly 400 located on both sides of the clamp 200 can be moved simultaneously to allow the second needle bed 410 to discharge the battery. The specific steps are as follows: Simultaneously adjust the clamping members 230 on the back sides of the first clamping plate 210 and the second clamping plate 220, moving the first clamping plate 210 and the second clamping plate 220 towards the center, thereby clamping the battery cell.
