[0023] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0025] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0026] This embodiment provides a high-performance lithium metal battery anode integrated preparation equipment 010, which can be used to prepare battery anode sheets.

[0027] Please refer to Figure 1 and Figure 2 The high-performance lithium metal battery anode integrated preparation equipment 010 includes: a frame 100, an unwinding mechanism 101, a conveying module, and a processing pool group. The unwinding mechanism 101 is mounted on the frame 100 and is used to unwind the substrate. The conveying module is mounted on the frame 100 and is used to wind the substrate released from the unwinding mechanism 101. The processing pool group is vertically and vertically mounted on the frame 100. When the processing pool group rises to the working position, the substrate wound on the conveying module can be immersed in the processing liquid contained in the processing pool group. When the processing pool group descends to the standby position, at least a portion of the conveying module and the substrate wound on the conveying module are removed from the processing pool group.

[0028] When the working fluid contained in the treatment pool is not needed, the treatment pool can be lowered to the standby position so that at least part of the conveying module and the substrate surrounding the conveying module can be removed from the treatment pool. In this way, when cleaning and maintaining the treatment pool, it can be lowered to the standby position to reduce the interference of the substrate and the conveying module with the space inside the treatment pool, thereby reducing the difficulty of cleaning and maintaining the treatment pool and improving efficiency.

[0029] It should be noted that the aforementioned substrate can refer to copper foil, 3D copper foil, or aluminum foil, etc., without specific limitations.

[0030] It should also be noted that the high-performance lithium metal battery anode integrated preparation equipment 010 can be used for electroplating lithium metal and can be used as a mass production equipment for ultra-thin lithium metal anodes of lithium metal batteries.

[0031] Optionally, the processing pool assembly includes an electroplating pool 402 and an SEI immersion pool 404; the conveying module includes a conductive roller assembly and a first support roller assembly 310 mounted on the frame 100. Both the conductive roller assembly and the first support roller assembly 310 are used to wind the substrate, and the first support roller assembly 310 is located downstream of the conductive roller assembly in the direction in which the conveying module moves the substrate; wherein, when the processing pool assembly rises to the working position, the substrate wound on the conductive roller assembly can be immersed in the electroplating solution contained in the electroplating pool 402, and the substrate wound on the first support roller assembly 310 can be immersed in the SEI immersion solution contained in the SEI immersion pool 404; when the processing pool assembly descends to the standby position, the substrate wound on the conductive roller assembly is removed from the electroplating pool 402, and the first support roller assembly 310 and the substrate wound on the first support roller assembly 310 are removed from the SEI immersion pool 404.

[0032] When the processing pool group is in the working position, the substrate immersed in the electroplating solution in the electroplating pool 402 can be electroplated (e.g., electroplating lithium metal), while an artificial SEI film layer can be formed on the surface of the substrate immersed in the SEI wetting pool 404.

[0033] Since the first support roller assembly 310 is located downstream of the conductive roller assembly in the direction of the conveying module's transport of the substrate, during the process of transporting the substrate using the conveying module, the substrate can first be immersed in the electroplating solution contained in the electroplating bath 402 to form a metal film layer (e.g., a lithium metal layer), and then moved and immersed in the artificial SEI wetting solution contained in the SEI wetting bath 404 to form an artificial SEI protective layer on the surface of the metal film layer on the substrate. In this way, the formed artificial SEI protective layer can be used to isolate oxygen, thereby protecting the chemically active metal film layer (e.g., a lithium metal layer).

[0034] It should be understood that in other embodiments, when the processing pool assembly rises to the working position, only the substrate wrapped around the conductive roller assembly can be immersed in the electroplating solution contained in the electroplating pool 402, or only the substrate wrapped around the first support roller assembly 310 can be immersed in the SEI wetting solution contained in the SEI wetting pool 404.

[0035] It should be noted that the first support roller assembly 310 is located downstream of the conductive roller assembly in the direction of the conveying module's transport of the substrate. This means that when the conveying module transports the substrate, the substrate first passes through the conductive roller assembly and then passes through the first support roller assembly 310.

[0036] Optionally, the electroplating tank 402 is configured to continuously and dynamically change the plating solution. The electroplating tank 402 is also connected to an inlet pump and an outlet pump. The inlet pump is used to replenish the electroplating solution to the electroplating tank 402, and the outlet pump is used to extract the electroplating solution from the electroplating tank 402. By continuously adding and removing plating solution into the electroplating tank 402 through the inlet pump and outlet pump, continuous dynamic solution change is achieved, which ensures the stability of the metal ion concentration and other properties of the electroplating solution in the electroplating tank 402.

[0037] Optionally, the SEI impregnation tank 404 is configured for batch solution replacement, that is, after the artificial SEI impregnation solution in the SEI impregnation tank 404 is discarded, a new artificial SEI impregnation solution is replaced.

[0038] Optionally, the conductive roller assembly includes a first conductive roller 301, a second support roller assembly, and a second conductive roller 302 disposed on the frame 100 and used for winding the substrate; wherein the first conductive roller 301 and the second conductive roller 302 are located upstream and downstream of the second support roller assembly, respectively, in the direction in which the conveying module moves the substrate; when the processing tank assembly rises to the working position, the second support roller assembly and the substrate wound on the second support roller assembly are both located inside the electroplating tank 402, and the first conductive roller 301 and the second conductive roller 302 are both located outside the electroplating tank 402; when the processing tank assembly descends to the standby position, the first conductive roller 301, the second support roller assembly, and the second conductive roller 302 are all located outside the electroplating tank 402.

[0039] A first conductive roller 301 and a second conductive roller 302 are respectively arranged upstream and downstream of the second support roller assembly, which can form a double conductive roller arrangement at both ends to ensure the uniformity and stability of the overall current intensity of the electroplated substrate, and to ensure the uniformity and consistency of the metal film layer formed by electroplating.

[0040] A second support roller assembly is provided between the first conductive roller 301 and the second conductive roller 302 to facilitate the unfolding of the substrate using the second support roller assembly, ensuring the flatness of the substrate, and thus ensuring the uniformity, consistency and flatness of the metal film layer formed by electroplating.

[0041] Optionally, the second support roller assembly includes a plurality of first rollers 303 and a plurality of second rollers 304. The plurality of first rollers 303 are arranged sequentially at intervals along the direction from the first conductive roller 301 to the second conductive roller 302, and the plurality of second rollers 304 are also arranged sequentially at intervals along the direction from the first conductive roller 301 to the second conductive roller 302. The plurality of first rollers 303 are distributed above the plurality of second rollers 304, and the first rollers 303 and second rollers 304 are alternately distributed in the direction from the first conductive roller 301 to the second conductive roller 302. The substrate can be sequentially wound around the plurality of first rollers 303 and the plurality of second rollers 304 in an "S" shape.

[0042] Optionally, both the first roller 303 and the second roller 304 are rotatably mounted on the frame 100.

[0043] Of course, in other embodiments, the first roller 303 is mounted on the frame 100 via a motor mounted on the frame 100, and the motor can drive the first roller 303 to rotate.

[0044] Alternatively, in other embodiments, the second roller 304 is mounted on the frame 100 via a motor mounted on the frame 100, and the motor can drive the second roller 304 to rotate.

[0045] It should be noted that the first conductive roller 301 and the second conductive roller 302 are located upstream and downstream of the second support roller assembly, respectively, in the direction of the conveying module's transport of the substrate. This means that when the conveying module transports the substrate, the substrate passes through the first conductive roller 301, the second support roller assembly, and the second conductive roller 302 in sequence.

[0046] Optionally, the conductive roller assembly also includes a pressure roller disposed on the frame 100, which cooperates with at least one of the first conductive roller 301, the second support roller assembly, and the second conductive roller 302 to clamp the substrate.

[0047] For example, the conductive roller assembly includes a pressure roller that cooperates with the first conductive roller 301 to clamp the substrate. This reduces the problem of relative slippage between the substrate and the surface of the first conductive roller 301.

[0048] For example, the conductive roller assembly includes a pressure roller that cooperates with the second conductive roller 302 to clamp the substrate.

[0049] For example, the conductive roller assembly includes three pressure rollers, one of which cooperates with a first conductive roller 301 to clamp the substrate, another pressure roller cooperates with a second conductive roller 302 to clamp the substrate, and a third pressure roller cooperates with a first roller 303 or a second roller 304 to clamp the substrate.

[0050] Optionally, the treatment pool group further includes a first cleaning pool 401; the conveying module further includes a third support roller assembly 330 disposed on the frame 100 and used for winding the substrate; wherein the third support roller assembly 330 is located upstream of the conductive roller assembly in the direction in which the conveying module conveys the substrate; when the treatment pool group rises to the working position, the substrate wound on the third support roller assembly 330 can be immersed in the cleaning liquid contained in the first cleaning pool 401.

[0051] A third support roller assembly 330 is provided upstream of the conductive roller assembly, and a first cleaning tank 401 is configured to facilitate the cleaning of the substrate with the cleaning solution in the first cleaning tank 401 before electroplating, so as to reduce impurities and chemical residues on the surface of the substrate.

[0052] It should be noted that the third support roller assembly 330 is located upstream of the conductive roller assembly in the direction of the conveying module's transport of the substrate. This means that when the conveying module transports the substrate, the substrate first passes through the third conveying roller assembly and then moves to the conductive roller assembly.

[0053] It should also be noted that the third support roller assembly 330 is located upstream of the conductive roller assembly in the direction in which the conveying module moves the substrate. Specifically, the third support roller assembly 330 is located upstream of the first conductive roller 301 in the direction in which the conveying module moves the substrate.

[0054] Optionally, the processing pool assembly further includes a second cleaning pool 403; the conveying module further includes a fourth support roller assembly 340 disposed on the frame 100 and used for winding the substrate; wherein, the fourth support roller assembly 340 is located downstream of the conductive roller assembly in the direction in which the conveying module conveys the substrate; when the processing pool assembly rises to the working position, the substrate wound on the fourth support roller assembly 340 can be immersed in the cleaning liquid contained in the second cleaning pool 403; when the processing pool assembly descends to the standby position, the fourth support roller assembly 340 and the substrate wound on the fourth support roller assembly 340 are removed from the second cleaning pool 403.

[0055] A fourth support roller assembly 340 is provided downstream of the conductive roller assembly, and a second cleaning tank 403 is configured to facilitate the removal of excess electroplating solution by using the cleaning solution in the second cleaning tank 403 after electroplating.

[0056] It should be noted that the fourth support roller assembly 340 is located downstream of the conductive roller assembly in the direction in which the conveying module conveys the substrate. Specifically, the fourth support roller assembly 340 is located downstream of the second conductive roller 302 in the direction in which the conveying module conveys the substrate. That is, when the conveying module conveys the substrate, the substrate first passes through the second conductive roller 302 and then moves to the fourth support roller assembly 340.

[0057] Optionally, the treatment pool assembly further includes a third cleaning pool 405; the conveying module further includes a fifth support roller assembly 350 disposed on the frame 100 and used for winding the substrate; wherein, the fifth support roller assembly 350 is located downstream of the first support roller assembly 310 in the direction in which the conveying module moves the substrate; when the treatment pool assembly rises to the working position, the fifth support roller assembly 350 and the substrate wound around the fifth support roller assembly 350 can be immersed in the cleaning liquid contained in the third cleaning pool 405; when the treatment pool assembly descends to the standby position, the substrate wound around the fifth support roller assembly 350 is removed from the third cleaning pool 405.

[0058] A fifth support roller assembly 350 is provided downstream of the first support roller assembly 310, and a third cleaning tank 405 is configured so that after an artificial SEI film layer is formed on the surface of the substrate using SEI wetting liquid, the cleaning liquid in the third cleaning tank 405 can be used to wash away the excess wetting liquid on the surface of the substrate.

[0059] It should be noted that the fifth support roller assembly 350 is located downstream of the first support roller assembly 310 in the direction of the conveying module's transport of the substrate. This means that when the conveying module transports the substrate, the substrate first passes through the first support roller assembly 310 and then moves to the fifth support roller assembly 350.

[0060] Optionally, the electroplating tank 402, the SEI immersion tank 404, the first cleaning tank 401, the second cleaning tank 403, and the third cleaning tank 405 are connected together.

The first support roller assembly 310 includes a support roller and a motor that is driven to drive the support roller. The motor is mounted on a frame 100 and is used to drive the support roller to rotate. Thus, the rotating support roller can be used to drive the substrate surrounding the support roller to move.

[0079] The testing equipment includes, but is not limited to, online surface density components, thickness detection components, and CCD vision uniformity detection components.

[0080] It should be noted that, please refer to Figure 3 The high-performance lithium metal battery anode integrated preparation equipment 010 can be entirely set inside the glove box 910, so that the glove box 910 can isolate the air and can be filled with inert gas to meet the inert gas environment required for electroplating.

[0081] The glove box 910 is also equipped with a waste liquid collection tank 920 for collecting waste liquid discharged from the electroplating tank 402, the SEI immersion tank 404, the first cleaning tank 401, the second cleaning tank 403 and the third cleaning tank 405.

[0082] For example, the outlet pump connected to the electroplating tank 402 can also be connected to the waste liquid collection tank 920 through the outlet pipe so that the waste liquid output from the electroplating tank 402 can enter the waste liquid collection tank 920; the SEI immersion tank 404 is connected to an outlet pipe, and the outlet pipe is equipped with a valve. The end of the outlet pipe away from the SEI immersion tank 404 is connected to the waste liquid collection tank 920. When the valve is open, the waste liquid in the SEI immersion tank 404 can flow into the waste liquid collection tank 920 through the outlet pipe.

[0083] The way the first cleaning tank 401, the second cleaning tank 403, and the third cleaning tank 405 discharge waste liquid into the waste liquid collection tank 920 is similar to that of the electroplating tank 402 or the SEI immersion tank 404, and will not be described in detail here.

[0084] The glove box 910 is also equipped with a power distribution box 930, which contains an electrical control integrated module. The electrical control integrated module is electrically connected to the high-performance lithium metal battery anode integrated preparation equipment 010. For example, the electrical control integrated module is electrically connected to the first conductive roller 301 and the second conductive roller 302.

[0085] In summary, the high-performance lithium metal battery anode integrated preparation equipment 010 of this utility model can be used to prepare battery anode sheets. This equipment is also more convenient for cleaning and maintaining the treatment pool group containing various treatment solutions such as electroplating solutions.

[0086] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
