[0028] Please see Figures 1 to 3 This utility model provides a hot-pressing formation apparatus 100, which includes a housing 10 and a plurality of formation drawers 20. The formation drawers 20 are movably disposed in the housing 10. Each formation drawer 20 includes a drawer body 21, clamping plates 22, and a pressurizing mechanism 23. The drawer body 21 houses the clamping plates 22 and the pressurizing mechanism 23. There are multiple clamping plates 22, which are spaced apart from each other. A battery vertical placement slot 24 is formed between two adjacent clamping plates 22. The battery vertical placement slot 24 houses a lithium battery. Each clamping plate 22 is provided with an electrical contact 25. The pressurizing mechanism 23 pushes the clamping plates 22 closer together to clamp the lithium battery. The electrical contact 25 abuts against the electrodes of the lithium battery.

[0029] Therefore, the hot-pressing formation apparatus 100 of the utility model embodiment, by adopting a drawer-type design, allows operators to easily pull out and push in the formation drawer 20 for batch loading and unloading of batteries. Compared with the traditional method of loading and unloading individual batteries one by one, the drawer-type design of the hot-pressing formation apparatus 100 greatly reduces loading and unloading time, thereby improving work efficiency.

[0030] Please see Figures 1 to 3 Specifically, the hot-pressing formation apparatus 100 includes a housing 10 constituting the main body of the apparatus 100. The housing 10 forms the external frame of the entire apparatus 100 and houses the formation drawers 20, which are movably disposed within the housing 10. Several formation drawers 20 are installed within the housing 10 in a drawer-type design. This allows operators to pull out and push in each formation drawer 20 for battery loading and unloading operations. Therefore, the ability to load and unload batteries by pulling out the formation drawers 20 improves the efficiency of lithium battery loading and unloading as well as the efficiency of hot-pressing formation. Furthermore, the design of the housing 10 facilitates the installation of multi-layer drawer structures, allowing for the storage of multiple battery groups for formation, thereby increasing the capacity and operating efficiency of the hot-pressing formation apparatus 100.

[0031] The formation drawer 20 specifically includes a drawer body 21, clamping plates 22, and a pressurizing mechanism 23. The drawer body 21 can accommodate the clamping plates 22 and the pressurizing mechanism 23 and provide space for fixing and protecting the lithium battery, so as to better adapt to the heat resistance requirements of the device in the hot-pressing formation process. The clamping plates 22 are key components for fixing and contacting the battery. Multiple clamping plates 22 are arranged inside the drawer body 21, spaced apart from each other. A battery vertical placement slot 24 is formed between every two adjacent clamping plates 22. Therefore, the lithium battery can be placed into the battery vertical placement slot 24 for hot-pressing formation. The clamping plates 22 are provided with energized contacts 25, which are specifically located in the battery vertical placement slot 24, so as to contact the battery electrodes when the battery is clamped by the clamping plates 22, providing the current path required for the battery formation process. Therefore, since the vertical battery slot 24 of the formation drawer 20 can restrict the position of the lithium battery, the alignment of the energized contact 25 with the electrode of the lithium battery is more convenient and accurate. When using it, the staff can directly put the lithium battery into the vertical battery slot 24 to achieve the effect of efficient loading and unloading of lithium batteries during hot pressing formation.

[0032] Furthermore, the pressurizing mechanism 23 is specifically connected to the clamping plates 22. The pressurizing mechanism 23 can push the clamping plates 22 closer together, clamping the lithium battery placed between the clamping plates 22. The energized contact 25 then abuts against the electrodes of the lithium battery, performing thermoforming on the lithium battery. When the lithium battery is placed into the battery vertical placement slot 24, the pressurizing mechanism 23 pushes the clamping plates 22 toward the lithium battery, making it come into close contact with the energized contact 25, achieving electrode docking. This pressurizing mechanism 23, designed in this way, can adjust the pressure as needed, thereby adapting to batteries of different specifications and shapes, achieving the effect of improving the stability of the formation process.

[0033] Therefore, a vertical battery placement groove 24 is formed between the clamping plates 22 inside the formation drawer 20, and a pressure mechanism 23 is used to push the clamping plates 22 closer together to clamp the vertically placed lithium battery. This ensures that the lithium battery maintains its vertical orientation during the hot-pressing formation process, allowing the electrolyte inside the lithium battery to participate in the film-forming reaction in a timely manner, improving the quality of the SEI film, and ensuring sufficient electrolyte wetting, thus reducing lithium plating. This contributes to improving the quality of the lithium battery.

[0034] Please see Figures 1 to 3 For the hot-pressing formation process of lithium batteries, the operator inserts the lithium batteries into the vertical placement slots 24 of the formation drawer 20. The lithium batteries are placed sequentially into the vertical placement slots 24 between each pair of clamping plates 22, ensuring they are placed vertically. After the lithium batteries enter the vertical placement slots 24, the pressurizing mechanism 23 is activated, pushing the clamping plates 22 closer together, so that the energized contacts 25 on the clamping plates 22 contact the electrodes of the lithium batteries and apply appropriate pressure. During hot-pressing formation, current is introduced into the battery through the energized contacts 25, performing charge-discharge cycles and activating the battery's chemical properties. At this time, due to the tight clamping of the pressurizing mechanism 23 and the clamping plates 22, the battery can be stably maintained in electrode contact, ensuring an uninterrupted current path and improving the reliability of the formation effect.

[0035] Therefore, in this embodiment of the utility model, after the hot-pressing formation apparatus 100 adopts a drawer-type design, the operator can easily pull out and push in the formation drawer 20 for batch loading and unloading of batteries. Compared with the traditional method of loading and unloading individual batteries one by one, this design greatly reduces the loading and unloading time and achieves the effect of improving work efficiency. At the same time, the clamping plates 22 inside the formation drawer 20 form a battery vertical placement groove 24, and the clamping plates 22 are pushed closer together by the pressurizing mechanism 23 to clamp the vertically placed lithium batteries, thereby maintaining the vertical posture of the lithium batteries during the hot-pressing formation process. This design allows the electrolyte inside the battery to fully participate in the film formation reaction, improves the quality of the SEI film, and ensures uniform wetting of the electrolyte, reducing lithium plating, thereby effectively achieving the effect of overall lithium battery quality.

[0036] Please see Figures 1 to 3Furthermore, regarding the structure of the energized contact 25, in one possible embodiment, the energized contact 25 is strip-shaped and extends along the height direction of the clamp 22.

[0037] Specifically, the energized contact 25 is designed as a strip structure extending along the height of the clamping plate 22. This strip-shaped energized contact 25 covers the entire height of the battery, ensuring stable contact between the electrodes and the contact, and guaranteeing uniform current conduction. The strip-shaped energized contact 25 not only improves the stability of current transmission during the formation process but also adapts to the needs of batteries of different sizes, further enhancing the versatility and contact effect of the hot-pressing formation apparatus 100. Furthermore, the strip-shaped design of the energized contact 25 eliminates the need for time-consuming and laborious adjustments to the clamping plate 22 to align the lithium battery and the contacts, further improving the loading and unloading efficiency of the hot-pressing formation process.

[0038] Please see Figures 1 to 3 Furthermore, the forming drawer 20 also includes a mating part 26, and the pressurizing mechanism 23 pushes the clamping plate 22 to move along the mating part 26.

[0039] Specifically, the mating part 26 is specifically located at the bottom of the drawer body 21. The mating part 26 can be integrally formed with the drawer body 21. It is made on the basis of the bottom plate of the drawer body 21 to provide support for the stable movement of the clamping plate 22. The mating part 26 can be a slide rod or a slide groove.

[0040] The pressurizing mechanism 23 pushes the clamping plate 22 to move smoothly along the mating part 26, enabling the clamping plate 22 to approach and clamp the battery during the formation process. The sliding rod or groove design of the mating part 26 effectively guides the movement path of the clamping plate 22, allowing it to slide along a predetermined direction under the action of the pressurizing mechanism 23. In this way, the clamping plate 22 can smoothly approach during pressurization, avoiding deviation or unevenness during clamping, thereby ensuring that the lithium battery maintains a stable clamping state during the hot-pressing formation process, which helps to improve the lithium battery formation effect and battery quality.

[0041] Please see Figures 1 to 3 Furthermore, the chemically formed drawer 20 also includes a guide rod 27, the drawer body 21 houses the guide rod 27, the guide rod 27 passes through each clamping plate 22, and the pressure mechanism 23 pushes the clamping plate 22 to move along the guide rod 27.

[0042] Specifically, the drawer body 21 also houses a guide rod 27, and the pressurizing mechanism 23 pushes the clamping plates 22 to move along the guide rod 27. The guide rod 27 guides the movement of each clamping plate 22. The guide rod 27 passes through each clamping plate 22, and both ends of the guide rod 27 are fixed to the inner wall of the drawer body 21. The guide rod 27 is arranged inside the formation drawer 20, and the design of the guide rod 27 passing through the clamping plates 22 ensures that each clamping plate 22 remains parallel and stable during movement, without tilting or shifting. This guide rod 27 guiding structure enhances the movement accuracy and stability of each clamping plate 22, helping to avoid poor electrode contact caused by misalignment of the clamping plates 22. At the same time, the fixed design of the guide rod 27 improves the overall structural strength of the formation drawer 20, ensuring that the clamping plates 22 maintain the correct position even when pressure is applied during the hot-press formation process in the hot-press formation device 100, thereby improving the lithium battery formation effect and product consistency.

[0043] Furthermore, in one possible implementation, the formation drawer 20 also includes a heating module (not shown), which is embedded in the clamping plate 22, or the heating module is embedded in the drawer body 21.

[0044] Specifically, a heating module can be used to provide a hot-pressing environment for the hot-pressing formation apparatus 100. The heating module can be embedded in the clamping plate 22 or the drawer body 21 to provide the necessary heat during the formation process. The heating module is configured to provide temperature for the hot-pressing formation reaction of the lithium battery.

[0045] When the heating module is embedded in the clamping plate 22, each clamping plate 22 can be heated individually, enabling more precise control of the temperature environment around the lithium battery. This ensures that each lithium battery receives uniform heat, thereby improving the formation quality of the SEI film and reducing film formation defects caused by uneven temperature.

[0046] When the heating module is embedded in the drawer body 21, the temperature inside the entire drawer body 21 can rise evenly. This can meet the heating needs of a large number of batteries, and the structure is simpler, achieving cost savings, while also providing a stable and consistent thermal environment for all batteries.

[0047] Preferably, the heating module can be a heating resistance wire.

[0048] Please see Figures 1 to 3 Furthermore, in one possible implementation, the pressurizing mechanism 23 includes a cylinder 231 and a telescopic rod 232, wherein the cylinder 231 pushes the clamping plate 22 through the telescopic rod 232.

[0049] Specifically, the pressurizing mechanism 23 can be designed to include a cylinder 231 and a telescopic rod 232, wherein the cylinder 231 pushes the clamping plate 22 via the telescopic rod 232. This design allows the clamping plate 22 to move flexibly and stably during the formation process, ensuring that appropriate pressure is applied to the battery. The cylinder 231 can be embedded in the drawer body 21, providing a stable and controllable pressure source. By adjusting the air pressure of the cylinder 231, the pressure applied by the clamping plate 22 can be precisely controlled to accommodate batteries of different specifications and requirements, thereby enhancing the versatility and adaptability of the hot-pressing formation apparatus 100. The telescopic rod 232 connects the cylinder 231 and the clamping plate 22. Specifically, the telescopic rod 232 is connected to the clamping plate 22 closest to the cylinder 231. The telescopic rod 232 can transmit the power generated by the cylinder 231 to the clamping plate 22. Under the action of the cylinder 231, the telescopic rod 232 pushes the clamping plate 22 to move smoothly closer to the battery, ensuring that the clamping force of the clamping plate 22 on the lithium battery is evenly distributed, and preventing the lithium battery from being subjected to uneven force or shifting.

[0050] Please see Figures 1 to 3 Furthermore, the chemically formed drawer 20 also includes a connecting strap 28. The drawer body 21 houses the connecting strap 28. There are multiple connecting straps 28, which are disposed on both sides of the clamping plate 22 and connected to each clamping plate 22.

[0051] Specifically, in this embodiment of the present invention, there are two connecting straps 28, which are set on both sides of the clamping plate 22. The connecting straps 28 are connected to both ends of each clamping plate 22. The purpose of setting the connecting straps 28 is to connect each clamping plate 22. When the pressurizing mechanism 23 presses the clamping plate 22, it can drive the clamping plate 22 to facilitate the collection of the lithium battery.

[0052] Preferably, the connecting strip 28 can be made of nylon. The nylon connecting strip 28 has high strength and wear resistance, and also has a certain degree of elasticity, which can effectively cope with the temperature and pressure changes that may occur during the hot pressing process.

[0053] Please see Figures 1 to 3 Furthermore, the surface of the chemically formed drawer 20 is provided with a drawer handle 30.

[0054] Specifically, for the formation drawer 20, each drawer surface is provided with a drawer handle 30, which can be in the form of a knob. To ensure that the operator can easily grip the handle when installing or removing batteries, the shape of the handle should be ergonomic, easy to operate, and able to withstand a certain amount of force, ensuring that there is no excessive resistance or discomfort when pulling out or pushing in the formation drawer 20.

[0055] In addition, the drawer handle 30 can be made of durable, corrosion-resistant materials (such as stainless steel or plastic) to withstand the high temperature and chemical environment during the chemical process, ensuring that it will not be damaged by high temperature or chemical corrosion during long-term use.

[0056] Please see Figures 1 to 4 Furthermore, the hot pressing formation apparatus 100 also includes a main controller 40; each formation drawer 20 is provided with a sub-controller 29, and the controller is electrically connected to each sub-controller 29 respectively.

[0057] Specifically, the hot pressing formation apparatus 100 is also equipped with a main controller 40, which is used to control the operation of the hot pressing formation apparatus 100. The main controller 40 can be an MCU or a microcontroller, etc.

[0058] The main controller 40 can be installed separately from the housing 10, or it can be installed inside the housing 10. Specifically, the main controller 40 can be installed inside the housing 10 on a layer other than the drawer 20. That is, the main controller 40 can be installed above or below the drawer 20.

[0059] Each formation drawer 20 is equipped with a sub-controller 29, and the main controller 40 is electrically connected to each sub-controller 29. The sub-controller 29 can be integrated into the formation drawer 20, or the sub-controller 29 can be set separately from the formation drawer 20.

[0060] Therefore, in the hot pressing formation apparatus 100, each formation drawer 20 is equipped with a sub-controller 29 to independently control the formation drawer 20, thus avoiding resource waste when not in use. The hot pressing formation apparatus 100 also includes a master controller 40 that controls each sub-controller 29, and the master controller 40 is electrically connected to each sub-controller 29. The master controller 40 can be an MCU or a microcontroller, etc.

[0061] Furthermore, in one possible implementation, the housing 10 is made of steel plate. Specifically, the housing 10 is made of steel plate. And when each formation drawer 20 is pushed into the housing 10, the hot-pressing formation apparatus 100 is completely sealed to provide a constant temperature environment for the hot-pressing formation process of the lithium battery.

[0062] For the specific formation process of the hot-pressing formation apparatus 100, the operator first pulls out the single-layer formation drawer 20, and the heating resistance wire starts heating when controlled by the main controller 40. Each lithium battery is placed vertically between each layer of pressure clamping plates 22, with the air bladder of the lithium battery facing upwards and the battery cell aligned with the energized contact piece 25 on the left and right sides of the clamping plate 22. After alignment, it is ensured that there is a lithium battery between each adjacent clamping plate 22 and that it is in contact with the energized contact piece 25. Then, the drawer is pulled out, pushed into the housing 10, and locked. Then, the pressure mechanism 23 is activated, which drives the clamping plates 22 to move, so that the clamping plates 22 move closer to each other, pressing the electrodes of each lithium battery and maintaining a constant pressure. At this time, the electrodes of the lithium battery gradually approach and press against the energized contact piece 25, and are energized to carry out formation. After the formation is completed, the personnel first pressurize the mechanism 23, causing the telescopic rod 232 of the pressurizing mechanism 23 to retract. At this time, each clamp 22 is gradually loosened by the connecting straps 28 at both ends. Finally, the formed lithium battery is manually removed to complete the entire hot pressing formation process.
