Description

Technical Field

[0001] The utility model relates to the technical field of battery core disassembly and testing, and more specifically to a battery core disassembly and protection system. Background Art

[0002] Currently, battery cell disassembly is a key analytical method that plays an important role in revealing the causes of battery cell failure, exploring failure mechanisms, and conducting comprehensive product analysis. By disassembling the battery cells in detail, technicians can deeply understand the various performance changes and internal structure changes of the battery during use, providing important information for battery design optimization and life prediction. This process can not only help improve the safety and reliability of battery products, but also has guiding significance for subsequent links such as battery recycling and material reuse.

[0003] Although cell disassembly technology plays an indispensable role in battery analysis and testing, existing disassembly methods and equipment face many challenges. The industry usually adopts a standardized disassembly process to avoid dangers during the disassembly process, such as short circuits between the positive and negative electrodes. In addition, the prior art also uses an integrated cell disassembly box to fix the battery and cut the outer shell to expose the cell, thereby separating the diaphragm and electrodes in the cell, thereby achieving safe disassembly. These methods and equipment have improved the safety and efficiency of the disassembly process to a certain extent.

[0004] However, the existing technical solutions still have obvious limitations. First, even with a standardized disassembly process, it is impossible to completely avoid the risk of positive and negative electrode short circuits, heat release, or even fire caused by electrode debris or electrode powder loss during the disassembly process. These problems not only increase the danger of disassembly operations, but also seriously affect the efficiency and quality of disassembly. Secondly, although the integrated disassembly box can protect operators to a certain extent and avoid direct contact with batteries that may short-circuit, it does not fundamentally solve the technical problem that the positive and negative electrodes are prone to short circuits and fires during the disassembly of the battery cells.

[0005] In summary, although the industry has improved the safety and operational efficiency of battery cell disassembly to a certain extent through standardized disassembly processes and integrated disassembly boxes, the existing technical solutions still have shortcomings. These shortcomings include but are not limited to: there are still high safety risks during the disassembly process, and the problem of short circuits and fires between the positive and negative poles during battery cell disassembly cannot be fundamentally solved. These defects limit the further development and application of battery cell disassembly technology, and it is urgent to solve these problems through technological innovation to ensure the safety, efficiency and reliability of the battery cell disassembly process.

[0066] As mentioned above, the heating device 3 is used to heat the inside of the sealed protection box 1, so that the temperature inside the box reaches a certain temperature under the premise of being controllable, so that the electrolyte solvent in the battery cell 200 to be disassembled can be vaporized.

[0067] As mentioned above, the carrying base 2 is used to carry the battery cell 200 to be disassembled.

[0068] As mentioned above, the size of the sealed protection box 1 is based on the size that can accommodate the battery cell 200 to be disassembled, and the box can reach a vacuum state by evacuating the vacuum.

[0071] In the utility model, a battery cell disassembly protection system 100 is adopted, and a battery cell 200 to be disassembled is placed in a sealed protective box 1, and then a vacuum device 8 is used to perform a vacuum operation to enable the box to reach a vacuum state, and then the sealed protective box 1 is heated by a heating device 3 to make the temperature reach a predetermined temperature, at which time the electrolyte solvent of the battery cell is directly gasified at high temperature; nitrogen is then input into the box through a nitrogen device 4 to make the gas flow, and then a vacuum operation is performed, and the nitrogen device 4 and the vacuum device 8 are repeatedly coordinated, so that the gas after the electrolyte solvent in the box is replaced by nitrogen, and then the processed battery cell can be taken out and directly disassembled at normal temperature and pressure, so that the electrolyte solvent can be gasified and removed before the disassembly operation is performed, fundamentally solving the safety problem of battery cell disassembly caused by short circuit between the positive and negative electrodes.

[0072] The utility model places the battery cell 200 to be disassembled into a sealed protective box 1, heats it through a heating device 3, and uses a vacuum device 8 and a nitrogen device 4 to perform a "vacuum-heating-vacuum-gas replenishment" cycle process, so that the electrolyte solvent in the battery cell 200 to be disassembled is gasified at high temperature and extracted through nitrogen replacement to achieve the purpose of removal, cuts off the ion path between the positive electrode plate and the negative electrode plate, and fundamentally eliminates the problem of battery cell fire caused by positive and negative electrode short circuit during battery cell disassembly, which not only ensures the safety of operators, but also ensures the smooth disassembly of the battery cell, can obtain expected experimental results, and ensures the safety, efficiency and reliability of the battery cell disassembly process.

[0073] Furthermore, the heating device 3 includes a pulse heating module 31 and an electric heating element 32;

[0074] The electric heating element 32 is arranged in the sealed protection box 1;

[0075] The pulse heating module 31 is electrically connected to the electric heating element 32 .

[0076] As mentioned above, the electric heating element 32 may be an electric heating wire, which is heated up under the control of the pulse heating module 31, thereby achieving heating inside the box.

[0077] For further reference, Figure 2 , the battery cell disassembly protection system 100 further includes an airflow fan device 5;

[0078] The airflow fan device 5 is disposed in the sealed protection box 1 .

[0079] As mentioned above, in the utility model, the sealed protection box 1 is a box with a certain space size. When heating and "replacing" the gasified electrolyte solvent gas with nitrogen gas, a certain processing time is required to make the gas flow in the box and flow out of the box. If the space in the box is large, there will be problems such as long time, low efficiency and possible gas residue.

[0080] In order to further improve the heating effect and gas replacement effect in the sealed protective box 1, in the utility model, an airflow fan device 5 is arranged in the sealed protective box 1 for controllably disturbing the airflow, thereby improving the heating effect and improving the removal effect of the electrolyte solvent in the battery cell by promoting the flow of air.

[0081] Furthermore, the airflow fan device 5 includes a fan base 51, a rotating disk 52, an angle adjustment shaft 53 and an airflow fan 54;

[0090] The object-carrying base 2 may be provided with an object-carrying motor and a transmission mechanism. The object-carrying motor outputs power, which drives the rotating shaft 22 to rotate through the transmission mechanism, thereby controlling the rotation of the object-carrying platform 23 .

[0091] During heating, the position of the electric heating element 32 in the sealed protective box may have a certain influence on the heating effect. In order to further improve the heating effect and efficiently vaporize the electrolyte solvent in the battery cell 200 to be disassembled, the angle can be adjusted by rotating the carrier base 2, or continuous rotation can be performed during heating to make the heating more uniform, improve the heating effect, and the vaporization effect, thereby improving the processing efficiency.

The two gases will directly enter the pump oil of the oil pump or the water body of the water pump, and may evaporate into the air to a certain extent. On the one hand, the gas evaporates from the vacuum device 8 into the air, polluting the air and causing health effects on R&D personnel. On the other hand, the gas enters the vacuum device 8, such as a vacuum oil pump or a vacuum water pump, and pollutes the water body and pump oil, causing corrosion problems to the equipment.

[0107] As mentioned above, the air suction part 62 includes a first support body 621 and an air suction port 622. The first support body 621 is vertically arranged, and the air suction port 622 is connected to the upper end of the first support body 621 and extends from the end to the center of the circle to form an "L" shaped structure.

[0108] As mentioned above, the first support body 621 is provided with a first motor 624 and a first pulley 623 at the lower end thereof, so that the first motor 624 drives the pulley to move along the first outer ring movable rail 61 .

[0112] The blowing part 42 is connected to the second outer ring movable rail 41, and the blowing part 42 can move along the first outer ring movable rail 61 surrounding the inner circle of the second outer ring movable rail 41 and the object carrying base 2 in the middle;

The loading base 2 is in the middle, the first outer ring movable rail 61 is on the outer circle of the loading base 2, and the second outer ring movable rail 41 is on the outer circle of the first outer ring movable rail 61.

[0115] In the present invention, in order to realize the efficient processing operation of suction and blowing, the suction part 62 for suction and the blowing part 42 for blowing nitrogen are both arranged around the object carrier base 2, and can be moved to corresponding positions through corresponding moving tracks. For example, the suction part 62 is at the 12 o'clock position of the circle, and the blowing part 42 is at the 6 o'clock position of the circle. The blowing part 42 and the suction part 62 correspond to each other, so that during the nitrogen replacement process, the blowing part 42 and the suction part 62 can be started and operated at the same time, so as to realize the efficient discharge of the waste gas generated inside.

[0116] Further, the blowing portion 42 includes a second support body 421 and a blowing port 422;

[0119] The second support body 421 has a second pulley 423 and a second motor 424 at the lower end thereof;

[0120] The second motor 424 is used to drive the second pulley 423 to move, so that the blowing part 42 moves along the second outer ring moving rail 41 based on the second pulley 423 .

[0121] In a preferred embodiment, Figure 6 As shown, the loading platform 2 is in the middle, and the battery cell 200 to be disassembled is placed on the loading platform 2. The nitrogen device and the exhaust gas collection device 63 are adjusted along the outer ring movable rail to correspond to the blowing port 422 and the suction port 622, that is, one is at the 12 o'clock position and the other is at the 6 o'clock position. When or after the electrolyte solvent in the battery cell 200 to be disassembled in the middle is vaporized, the vaporized exhaust gas and aerosol are blown to the suction port 622 through the blowing port 422, forming an airflow belt, so that the airflow can be directly recovered by the exhaust gas collection device 63 more smoothly, efficiently and quickly.

[0122] In addition, the second outer ring movable rail 41 and the first outer ring movable rail 61 can not only realize the position adjustment of the suction port and the blowing port to improve flexibility, but also can move the two devices to the same position when they are no longer needed for operation, when neither device is needed, or when a larger space is needed. For example, both are moved to the "12 o'clock" position.
