Description

Technical Field

[0001] The invention relates to the technical field of electrode foil formation and immersion, in particular to a formation device and a formation method for producing low-voltage and high-specific-capacity electrode foil. Background Art

[0002] Low-voltage and high-specific-capacity electrode foil refers to a material made of positive aluminum foil and negative copper foil, used for conducting electricity and storing energy in energy storage devices such as lithium-ion batteries. During production, electrode foil usually requires a formation reaction to activate its electrode material so that it can undergo an effective electrochemical reaction. The formation process mainly includes electrolyte immersion, charging, and post-processing.

[0003] Existing formation devices use a variety of methods to achieve electrode foil immersion. For example, a Chinese invention patent with publication number CN112185716B discloses an electrode foil formation device, including a formation tank, a winding roller is arranged on one side of the upper end of the formation tank, and two upper guide rollers are installed at equal distances on the upper end of the formation tank, located on one side of the winding roller, and a water receiving tank is arranged on the inner side of the formation tank directly below the upper guide roller, and three infusion tubes are distributed at equal distances from top to bottom on one outer side of the formation tank, and a liquid storage tank is arranged on the outer side of the formation tank, located on one side of the infusion tube;

[0004] Since the original state of the electrode foil is usually in a rolled shape, when the existing formation device is soaking the electrode foil, the electrode foil curled inside cannot fully contact with the electrolyte and is not soaked enough, which affects the uniformity and quality of the formed film. For example, in the above-mentioned prior art, the device uses a traction method to soak and move the electrode foil. This soaking method cannot control the soaking time of the electrode foil, so that the electrode foil will be soaked unevenly. At the same time, the electrolyte in the formation tank of the device is in a static state. Long-term static state will cause precipitation of the internal electrolyte, resulting in different soaking degrees of the electrode foil in different areas, affecting the soaking effect;

[0005] Therefore, it is urgent to design a formation device and a formation method for producing low-voltage and high-specific-capacitance electrode foil to solve the above problems. Summary of the invention

[0022] S2.

[0026] S6. After the drying is completed, the top cover plate is continuously lifted up until the electrode foil is moved up and out of the soaking inner box, and the electrode foil on the two winding rollers is taken out to complete the soaking operation.

[0027] The present invention provides a formation device and a formation method for producing low-voltage and high-specific-capacitance electrode foil. It has the following beneficial effects:

[0028] 1. When the electrode foil is soaked, the servo motor and the two winding rollers cooperate to realize the forward and reverse winding of the electrode foil while soaking it. The curled electrode foil can be pulled out to make it fully contact with the electrolytic forming liquid. The overall soaking time is the same and controllable, which can effectively improve the soaking effect of the electrode foil.

[0029] 2. When the electrode foil is soaked, the electrolytic solution can be automatically soaked by the downward movement of the sliding plate during the placement of the electrode foil, and the electrolytic solution can be automatically separated when the electrode foil is moved upward, so that the electrode foil can be quickly separated from the electrolytic solution, which can effectively improve the efficiency of subsequent drying.

[0030] 3. When the electrode foil is soaked, the electrolytic impurities attached to the electrode foil can be scraped off and the bubbles in the electrolytic solution can be scraped off by the cooperation of the extrusion spring and the extrusion scraper rod while the electrode foil is pulled out, so as to avoid the generation of too many bubbles during soaking and affect the uniform penetration of the electrolytic solution, thereby improving the soaking effect.

[0031] 4. When the electrode foil is soaked, the servo motor can be used to drive multiple impellers to rotate, and the electrolytic solution can be stirred during rotation, which effectively improves the fluidity of the electrolytic solution, makes it evenly mixed and has roughly the same internal concentration, and avoids uneven soaking and penetration.

[0032] 5.

DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Example 1: Reference Figure 1-Figure 5 as well as Figure 8 , a formation device for producing low-voltage and high-specific-capacity electrode foil, comprising a formation outer box 1 and an electrode foil 12 to be soaked;

[0051] The formation device also includes:

[0052] The storage unit is used to place and take the electrode foil 12, and includes an immersion inner box 4 arranged in the formation outer box 1. A top cover plate 2 for sealing is slidably installed in the immersion inner box 4. The top cover plate 2 is slidably matched with the immersion inner box 4. After the top cover plate 2 is arranged on the upper part of the immersion inner box 4, the immersion inner box 4 can be closed;

[0053] Two winding rollers 11 are installed on the top cover plate 2 through a sliding assembly, and the electrode foil 12 is wound between the two winding rollers 11. The sliding assembly includes two groups of connecting rods 13 fixedly installed at the lower part of the top cover plate 2, and the lower parts of the two groups of connecting rods 13 are fixedly installed with sliding plates 15. Two limit sliding rods 7 are fixedly installed in the soaking inner box 4, and the two sliding plates 15 are respectively engaged and slidably installed on the two limit sliding rods 7;

[0054] When the top cover plate 2 is raised or lowered, the two sliding plates 15 will be driven to rise or fall through the two groups of connecting rods 13 at the bottom thereof (each group of connecting rods 13 includes two connecting rods 13). When the sliding plates 15 are raised or lowered, they will slide vertically on the two limit sliding rods 7, thereby improving the stability of the lifting and falling movement of the top cover plate 2 and avoiding position deviation.

[0055] A driven mechanism is installed between the two sliding plates 15, and the driven mechanism includes two driven rods 18 rotatably installed on the two sliding plates 15, and the two winding rollers 11 are respectively sleeved on the two driven rods 18;

[0056] The two winding rollers 11 are used to wind the electrode foil 12. When the electrode foil 12 needs to be soaked, the top cover plate 2 is first pulled up to drive the two winding rollers 11 to move to the outside of the soaking inner box 4, and then the rolled electrode foil 12 is sleeved on one of the winding rollers 11, and then pulled out and wound on the other winding roller 11 to form the electrode foil 12 attached to the instruction manual. Figure 5 In the state shown, the installation of the electrode foil 12 is completed;

[0057] The two driven rods 18 are both threadedly mounted with a threaded disk 20 for positioning the winding roller 11. After the rolled electrode foil 12 is sheathed, the threaded disk 20 can be rotated to move on the driven rod 18, and the threaded disk 20 is fitted with the side of the electrode foil 12 to complete the side positioning of the electrode foil 12, thereby preventing the electrode foil 12 from falling off during immersion.

[0058] A transmission belt 17 is sleeved between the two driven rods 18, and the transmission belt 17 is used to connect the two driven rods 18 so that the two driven rods 18 can rotate together, thereby allowing the two winding rollers 11 to rotate in the same direction and at the same speed, so that when one of the winding rollers 11 rotates to release the electrode foil 12, the other winding roller 11 can rotate synchronously to complete the winding of the electrode foil 12.

[0059] The liquid conducting component is arranged in the immersion inner box 4 and is used to cooperate with the sliding component to realize the conduction of the electrolytic liquid and complete the immersion of the electrode foil 12;

[0060] The soaking unit is arranged in the soaking inner box 4, and is used to soak, remove impurities and dry the electrode foil 12, improve the uniformity of soaking of the electrode foil 12, and realize the rapid removal of impurities and drying of the electrode foil 12 after soaking, so as to facilitate the subsequent charging of the electrode foil 12;

[0061] Example 2: Reference Figure 3-Figure 6 as well as Fig.13The difference between this embodiment and the first embodiment is that the liquid guide assembly includes a lifting partition 8 slidably mounted in the soaking inner box 4, and a plurality of lifting springs 9 for resetting the lifting partition 8 are fixedly mounted between the lifting partition 8 and the bottom wall of the soaking inner box 4, and the lower part of the lifting partition 8 in the soaking inner box 4 is filled with electrolytic liquid;

[0062] The electrolytic solution is filled in the lower part of the lifting partition 8 in the initial state, and the lifting partition 8 is supported by a plurality of lifting springs 9 in the initial state and does not contact with the electrolytic solution.

[0063] A liquid exchange pipe 3 is fixedly connected between the immersion inner box 4 and the formation outer box 1, and the liquid exchange pipe 3 is used for recovering and replenishing the electrolytic formation liquid;

[0064] A fixed frame 10 is fixedly installed in the lifting partition 8, and a filter frame 34 is fixedly installed in the fixed frame 10. The filter frame 34 is used to realize the conduction of the electrolytic liquid and the filtration of the impurities soaked. The lower parts of the two sliding plates 15 are fixedly installed with pressing rods 36, and a receiving cross bar 35 matched with the two pressing rods 36 is fixedly installed on the lifting partition 8;

[0065] When the top cover plate 2 moves downward and drives the sliding plate 15 to move downward, the sliding plate 15 will drive the pressing rod 36 at its lower part to move downward. When the pressing rod 36 moves downward to contact the receiving cross bar 35, the pressing rod 36 will continue to move downward to squeeze the receiving cross bar 35 to move downward, thereby driving the lifting partition 8 to move downward. The lifting partition 8 will squeeze the electrolytic solution at its lower part when it moves downward, so that the electrolytic solution passes through the filter frame 34 on the fixed frame 10 and then moves upward to the upper part of the lifting partition 8.

[0066] When the pressing rod 36 moves down to the maximum position, the lifting partition 8 moves down to the maximum position, and the two winding rollers 11 also move down to the maximum position. At this time, the electrolytic liquid on the lifting partition 8 can completely submerge the electrode foil 12 on the winding roller 11, and the electrode foil 12 can be soaked at this time.

[0067] When the lifting partition 8 moves downward, it squeezes the multiple lifting springs 9 at the lower part thereof. When the electrode foil 12 is taken, the pressing rod 36 moves upward under the action of the top cover plate 2 and releases the squeezing of the lifting partition 8. At this time, the lifting partition 8 automatically moves upward to the original position under the resetting action of the lifting springs 9, completing the automatic resetting.

[0068] The filter frame 34 is used to filter impurities generated during soaking. When the lifting partition 8 moves upward, the electrolytic liquid on its upper part will pass through the lower liquid of the filter frame 34, while the impurities in the electrolytic liquid will be blocked by the filter frame 34 and cannot pass through, and will accumulate on the filter frame 34. The impurities on the filter frame 34 can be cleaned regularly to maintain the cleanliness of the electrolytic liquid.

[0069] Example 3: Reference Figure 4-Figure 12 The technical solution of this embodiment is different from that of the second embodiment in that the soaking unit includes a winding assembly, a cleaning assembly and a drying assembly, wherein the winding assembly is used to realize the winding of the electrode foil 12, the cleaning assembly is used to realize the cleaning of impurities during the winding process of the electrode foil 12, and the drying assembly is used to realize the drying of the electrode foil 12 after winding;

[0070] The winding assembly includes a servo motor 6 fixedly mounted in the formation outer box 1, a driving roller 27 is arranged on the driving end of the servo motor 6, a fixed disk 19 is fixedly mounted on the driving roller 27, a hexagonal engaging column 24 is slidably mounted in the fixed disk 19, and the servo motor 6 drives the driving roller 27 to rotate when it is started, and the speed of the driving roller 27 can be adjusted by the servo motor 6;

[0071] A clamping mechanism is installed between the hexagonal clamping column 24 and the driven rod 18, and the clamping mechanism includes an electromagnetic disk 22 fixedly installed on the outside of the hexagonal clamping column 24, and a plurality of return springs 23 are fixedly installed between the electromagnetic disk 22 and the fixed disk 19, a permanent disk 21 matched with the electromagnetic disk 22 is fixedly installed on the driven rod 18, and a clamping hole matched with the hexagonal clamping column 24 is fixedly installed on the driven rod 18;

[0072] When the top cover plate 2 moves down to the maximum position, the sliding plate 15 and the winding roller 11 are both at the lowest position, and the midpoints of the driven rod 18 on the sliding plate 15 and the driving roller 27 of the servo motor 6 are on the same center line. At this time, the electromagnetic disk 22 can be energized. When the electromagnetic disk 22 is energized, it will generate magnetism and attract the permanent disk 21.

[0073] The electromagnetic disk 22 and the permanent disk 21 attract each other and approach each other, which will drive the hexagonal locking column 24 to move. When the electromagnetic disk 22 and the permanent disk 21 are attached to each other, the hexagonal locking column 24 will be locked into the locking hole in the driven rod 18 to complete the locking positioning. At this time, when the driving roller 27 rotates, it will drive the driven rod 18 to rotate through the fixed disk 19 and the hexagonal locking column 24, thereby driving the winding roller 11 to rotate to realize the release and extension or rewinding of the electrode foil 12;

[0074] When the electromagnetic disk 22 moves, multiple reset springs 23 will be stretched. When the soaking is completed, the electromagnetic disk 22 will be powered off and lose its magnetism. At this time, the reset spring 23 will automatically shrink and reset and drive the electromagnetic disk 22 to reset, thereby pulling the hexagonal locking column 24 back into the fixed disk 19, so that the hexagonal locking column 24 is separated from the driven rod 18, releasing the positioning of the driven rod 18, so that the driven rod 18 can be lifted and pulled out normally.

[0075] In a further embodiment, the cleaning assembly includes a support rod fixedly mounted on the connecting rod 13, a bogie 16 is rotatably mounted on the support rod through a damping spring shaft, an extrusion spring 26 is fixedly mounted on the bogie 16, and an extrusion scraper 25 for scraping impurities on the upper part of the electrode foil 12 is fixedly mounted on the lower part of the plurality of extrusion springs 26;

[0076] When the electrode foil 12 is placed (i.e., the electrode foil 12 has been wound between the two winding rollers 11), the damping spring shaft can be rotated to drive the bogie 16 to deflect, so that the extrusion scraper 25 at the lower part of the bogie 16 squeezes the electrode foil 12 under the action of the extrusion spring 26 to form the attached manual Figure 7 Status shown;

[0077] When the electrode foil 12 is pulled out or rewound in rotation, it will contact the extrusion scraper 25 when moving. At this time, the electrolytic impurities attached to the electrode foil 12 will be scraped off by the extrusion scraper 25, so that the electrolytic impurities will not adhere to the electrode foil 12. The extrusion scraper 25 can also scrape off the bubbles generated by the electrolytic solution during immersion, avoiding too many bubbles affecting the uniform penetration of the electrolytic solution, and further improving the immersion effect.

[0078] In a further embodiment, the drying assembly includes a linkage roller 28 rotatably mounted between the formation outer box 1 and the soaking inner box 4, the linkage roller 28 and the driving roller 27 are fixedly mounted with a driving gear, and a transmission toothed belt 29 is meshed between the two driving gears, and a plurality of intermediate rollers 30 are rotatably mounted between the formation outer box 1 and the soaking inner box 4, and each intermediate roller 30 is fixedly mounted with a transmission gear 31 meshing with the transmission toothed belt 29;

[0079] When the driving roller 27 rotates, it drives the driving gear on it to rotate. The driving gear on the driving roller 27 drives the transmission toothed belt 29 to drive with the cooperation of the driving gear on the linkage roller 28. When the transmission toothed belt 29 drives, it drives multiple transmission gears 31 meshing with it to rotate, thereby driving multiple middle rollers 30 to rotate together.

[0080] An air guide mechanism is installed in the immersion inner box 4, and the air guide mechanism includes a plurality of impellers 33 fixedly installed on a plurality of center rollers 30, and the plurality of impellers 33 are all located in the immersion inner box 4. When the electrode foil 12 is immersed, the servo motor 6 is started to drive the plurality of center rollers 30 to rotate, and the rotation of the plurality of center rollers 30 will drive the plurality of impellers 33 to rotate. Since the electrolytic liquid is located on the upper part of the lifting partition 8 during immersion, the electrolytic liquid will submerge the plurality of impellers 33. At this time, when the plurality of impellers 33 rotate, the electrolytic liquid will be stirred to a certain extent, thereby effectively improving the fluidity of the electrolytic liquid, making it evenly mixed and having roughly the same internal concentration, thereby avoiding uneven immersion penetration.

[0081] The soaking inner box 4 is provided with a plurality of one-way air supply pipes 32 for air supply, and the air inlet end of the one-way air supply pipe 32 is located outside the formation outer box 1, and the top cover plate 2 is provided with a plurality of air exchange holes 5 for air exchange, and a heating rack 14 for drying the electrode foil 12 is fixedly installed between the two sets of connecting rods 13;

[0082] When the electrode foil 12 is soaked, the electrolytic solution flows back and the electrode foil 12 moves up to a certain distance. At this time, the impeller 33 is separated from the electrolytic solution, and the servo motor 6 is started again to drive the multiple impellers 33 to rotate. At this time, when the multiple impellers 33 rotate, they will replenish air under the action of the one-way air replenishment pipe 32, and generate a certain wind force and airflow to blow upward, and the air is discharged through the air exchange hole 5 on the top cover plate 2, completing the replenishment and circulation of the airflow;

[0083] The impeller 33 starts the heating frame 14 to heat and dry the electrode foil 12 while blowing air. At the same time, the wind force and airflow can achieve rapid dehumidification and drying of the electrode foil 12, which has higher drying efficiency and facilitates the subsequent charging operation of the electrode foil 12.

[0084] The embodiment of the present invention further provides a formation method for producing a low-voltage high-specific-capacitance electrode foil, and a formation device for producing the electrode foil, comprising the following steps:

[0085] S1. When soaking the electrode foil 12, first pull out the top cover plate 2 and sleeve the electrode foil 12 between the two winding rollers 11, and then push the top cover plate 2 back into the soaking inner box 4 to complete the soaking preparation of the electrode foil 12;

[0086] S2, when the top cover plate 2 is pushed back, the liquid guide assembly is triggered to conduct the electrolytic solution in the immersion inner box 4, so that the electrode foil 12 is immersed in the electrolytic solution when it moves downward, and the immersion of the electrode foil 12 is completed;

[0087] S3, during the soaking process of the electrode foil 12, the winding assembly in the soaking unit is started to drive the electrode foil 12 to be wound between the two winding rollers 11, and the electrode foil 12 is fully contacted and soaked in the electrolytic solution during the winding process;

[0088] S4, while the electrode foil 12 is being wound, impurities on the electrode foil 12 are cleaned with the cooperation of the cleaning component, and the fluidity of the electrolytic solution is improved with the cooperation of the drying component, so as to further improve the soaking effect;

[0089] S5. After the soaking is completed, the top cover plate 2 is lifted to drive the electrode foil 12 to move up a certain distance, and the drying component is started to heat and dry the electrode foil 12, and the electrode foil 12 is blown while drying to improve the drying efficiency;

[0090] S6. After the drying is completed, the top cover plate 2 is continuously lifted up until the electrode foil 12 is moved up and out of the soaking inner box 4, and the electrode foil 12 on the two winding rollers 11 is taken out, and the soaking operation is completed.

[0091] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
