Description

Technical Field

[0001] This application relates to the field of all-solid-state battery technology, and in particular to a system for fabricating all-solid-state batteries. Background Technology

[0002] All-solid-state batteries may include at least one stacked cell, and each stacked cell may include a positive electrode and a negative electrode. In existing all-solid-state batteries, since the size of the positive electrode is usually smaller than the size of the negative electrode, when the positive and negative electrodes are stacked and subjected to isostatic pressing or flat pressing, steps are formed at the edges of adjacent positive and negative electrodes, generating shear forces. This can easily cause the edges of the positive and negative electrodes to break or fall off, leading to a short circuit inside the battery. Based on this, the inventors provide an all-solid-state battery in which the positive electrode is partially offset from the negative electrode along a first direction; the size of the positive electrode along a second direction is smaller than the size of the negative electrode along a second direction, and the positive electrode along the second direction is within the size range of the negative electrode, wherein the first and second directions intersect. Simultaneously, the stacked cell also includes a frame, which is disposed at the edge of the positive electrode extending beyond the negative electrode and at the edge of the negative electrode extending beyond the positive electrode. During isostatic pressing or flat plate pressing of this all-solid-state battery, the frame ensures that the stacked cells are subjected to uniform stress, thereby preventing shear forces at the edges of the positive and negative electrodes that could lead to edge breakage or powder shedding. However, existing all-solid-state battery fabrication systems are ill-suited to the processing requirements of this all-solid-state battery. Utility Model Content

[0036] This application provides a system for fabricating an all-solid-state battery, such as... Figures 1 to 8 As shown, the fabrication system for all-solid-state batteries includes:

[0037] The first electrode preparation device 100 is used to prepare the positive electrode 910;

[0038] The second electrode preparation device 200 is used to prepare the negative electrode sheet 920;

[0039] A first stacking device 300 is disposed downstream of the first wafer-making device 100 and the second wafer-making device 200, and is used to stack a positive electrode 910 and a negative electrode 920; wherein the positive electrode 910 is partially offset from the negative electrode 920 along a first direction, the size of the positive electrode 910 along a second direction is smaller than the size of the negative electrode 920 along a second direction, and the positive electrode 910 is disposed within the size range of the negative electrode 920 along the second direction, and the first direction intersects the second direction;

[0040] A first adhesive-forming apparatus 400 is disposed downstream of a first lamination apparatus 300 and is used to prepare an adhesive frame 930 on the edge portion of the positive electrode 910 extending beyond the negative electrode 920 and the edge portion of the negative electrode 920 extending beyond the positive electrode 910, so as to prepare a lamination unit 900.

[0041] like Figure 1 and Figure 2 As shown in this embodiment, by way of example, the fabrication system for an all-solid-state battery can be used to fabricate an all-solid-state battery. The all-solid-state battery may include at least one stacking unit 900, which may include a positive electrode 910, a negative electrode 920, and a photoresist frame 930. Correspondingly, the fabrication system may include a first sheet-making apparatus 100, a second sheet-making apparatus 200, a first stacking apparatus 300, and a first photoresist apparatus 400.

[0042] like Figure 1 and Figure 3As shown, the first electrode preparation device 100 can be used to prepare the positive electrode 910, and the second electrode preparation device 200 can be used to prepare the negative electrode 920. The first electrode preparation device 100 and the second electrode preparation device 200 can be configured as two parallel devices. The positive electrode 910 and the negative electrode 920 can be configured with the same shape and have dimensions along a first direction and a second direction, wherein the first direction may intersect with the second direction. In this embodiment, taking the first direction and the second direction as perpendicular as an example, both the positive electrode 910 and the negative electrode 920 are rectangular. The first direction can be the length direction of the positive electrode 910 and the negative electrode 920, and the second direction can be the width direction of the positive electrode 910 and the negative electrode 920. The size of the positive electrode 910 along the first direction can be less than or equal to the size of the negative electrode 920 along the first direction, and the size of the positive electrode 910 along the second direction can be less than the size of the negative electrode 920 along the second direction, that is, the size of the positive electrode 910 can be less than the size of the negative electrode 920.

[0043] like Figure 1 and Figure 3 As shown, the first stacking device 300 can be used to place the positive electrode 910 on one side of the negative electrode 920, that is, to perform stacking. It can be located downstream of the first electrode preparation device 100 and the second electrode preparation device 200, and can receive the positive electrode 910 prepared by the first electrode preparation device 100 and the negative electrode 920 prepared by the second electrode preparation device 200, respectively.

[0044] When the first stacking device 300 stacks the positive electrode 910 and the negative electrode 920, the positive electrode 910 and the negative electrode 920 can be partially offset along a first direction. That is, one end of the positive electrode 910 along the first direction can extend beyond the negative electrode 920, and the other end of the negative electrode 920 along the first direction can extend beyond the positive electrode 910. The positive electrode 910 is positioned within the size range of the negative electrode 920 along a second direction, that is, the vertical projection of the positive electrode 910 along the stacking direction is within the size range of the negative electrode 920. At this time, the edge portion of the positive electrode 910 extending beyond the negative electrode 920 may include one end of the positive electrode 910 extending beyond the negative electrode 920 along the first direction, and the edge portion of the negative electrode 920 extending beyond the positive electrode 910 may include one end of the negative electrode 920 extending beyond the positive electrode 910 along the first direction and the portion of the negative electrode 920 extending beyond the positive electrode 910 along the second direction; and the aforementioned edge portions are all formed with steps.

[0045] like Figure 1 and Figure 3As shown, the first adhesive-forming device 400 can prepare an adhesive frame 930 on the positive electrode 910 and the negative electrode 920. It can be positioned downstream of the first stacking device 300 and can receive the stacked positive electrode 910 and negative electrode 920 prepared by the first stacking device 300. The first adhesive-forming device 400 can arrange the adhesive frame 930 at the steps formed by the edges of the positive electrode 910 extending beyond the negative electrode 920 and at the steps formed by the edges of the negative electrode 920 extending beyond the positive electrode 910. It is easy to see that the adhesive frame 930 can be used to fill the gaps at the steps, so that when the stacking unit 900 undergoes isostatic pressing or flat plate pressing, the positive electrode 910 and negative electrode 920 of the stacking unit 900 can be subjected to uniform force, thereby avoiding shear forces at the edges of the positive electrode 910 and negative electrode 920.

[0046] It is understood that this application prepares a positive electrode 910 and a negative electrode 920 respectively using a first electrode preparation device 100 and a second electrode preparation device 200, and stacks the positive electrode 910 and the negative electrode 920 at a designated position using a first stacking device 300, and prepares a glue frame 930 at a designated position using a first glue preparation device 400. This allows the desired all-solid-state battery to be prepared. The all-solid-state battery allows the stacking unit 900 to be uniformly stressed during isostatic pressing or flat plate pressing, thereby avoiding shear force at the edges of the positive electrode 910 and the negative electrode 920, which could cause the edges to break or shed powder. Therefore, the all-solid-state battery preparation system provided by this application can meet the processing requirements of all-solid-state batteries.

[0047] Specifically, the first sheet-making apparatus 100 includes a first unwinding mechanism 110 and a first cutting mechanism 120. The first cutting mechanism 120 is located downstream of the first unwinding mechanism 110. The first unwinding mechanism 110 is used to unwind the roll of positive electrode sheet 910, and the first cutting mechanism 120 is used to cut the roll of positive electrode sheet 910 into positive electrode sheet 910.

[0048] like Figure 1 , Figure 3 and Figure 4As shown in this embodiment, the positive electrode sheet 910 can be exemplarily described as being cut from a roll of material. The first sheet-making apparatus 100 may include a first unwinding mechanism 110 for unwinding the roll of material containing the positive electrode sheet 910 and a first cutting mechanism 120 for cutting the unwound roll of material containing the positive electrode sheet 910 into positive electrode sheets 910. The first cutting mechanism 120 may be located downstream of the first unwinding mechanism 110. The first unwinding mechanism 110 may specifically include a first roll 111 and a first transfer roller 112, while the first cutting mechanism 120 may specifically be a cutting machine. The roll of the positive electrode 910 can be arranged on the first roll 111 and tensioned between the first roll 111 and the first cutting mechanism 120; while the first transmission roller 112 can be driven by a motor or other driving device, and can be arranged between the first roll 111 and the first cutting mechanism 120 and in contact with the roll of the positive electrode 910 to drive the roll of the positive electrode 910 to move.

[0049] Between the first roll 111 and the first cutting mechanism 120, a deviation correction mechanism 1010, a tension control mechanism 1020, and a roll material detection mechanism 1030 may also be provided. The deviation correction mechanism 1010 may include a deviation correction roller and is used to correct the deviation of the roll material of the positive electrode sheet 910. The tension control mechanism 1020 may include a tension adjustment roller, which can be movably set and is used to adjust the tension of the roll material of the positive electrode sheet 910 when unwinding. The roll material detection mechanism 1030 may include a vision detection system and is used to detect defects in the roll material of the positive electrode sheet 910 and issue an alarm when an abnormality is detected.

[0050] It is understood that in this embodiment, by setting the first sheet-making device 100 to at least the first unwinding mechanism 110 and the first cutting mechanism 120, the preparation and processing of the positive electrode sheet 910 is facilitated, so as to further stack the positive electrode sheet 910 and the negative electrode sheet 920.

[0051] Specifically, the second sheet-making device 200 includes a second unwinding mechanism 210 and a second cutting mechanism 220. The second cutting mechanism 220 is located downstream of the second unwinding mechanism 210. The second unwinding mechanism 210 is used to unwind the roll of negative electrode sheet 920, and the second cutting mechanism 220 is used to cut the roll of negative electrode sheet 920 into negative electrode sheet 920.

[0052] like Figure 1 , Figure 3 and Figure 4As shown in this embodiment, by way of example, the negative electrode sheet 920 can also be cut from a roll of material. The second sheet-making device 200 may include a second unwinding mechanism 210 for unwinding the roll of material containing the negative electrode sheet 920 and a second cutting mechanism 220 for cutting the unwound roll of material containing the negative electrode sheet 920 into negative electrode sheets 920. The second cutting mechanism 220 may be located downstream of the second unwinding mechanism 210. The structure of the second unwinding mechanism 210 is similar to that of the first unwinding mechanism 110. Specifically, it may include a second roll 211 and a second transfer roller 212. Similarly, the second cutting mechanism 220 may also be a cutting machine. The roll of negative electrode sheet 920 can be arranged on the second roll 211 and tensioned between the second roll 211 and the second cutting mechanism 220; while the second transmission roller 212 can be driven by a motor or other driving device, and it can be arranged between the second roll 211 and the second cutting mechanism 220 and in contact with the roll of negative electrode sheet 920 to drive the roll of negative electrode sheet 920 to move.

[0053] Between the second roll 211 and the second cutting mechanism 220, a correction mechanism 1010, a tension control mechanism 1020, and a roll material detection mechanism 1030 can also be provided. The functions of each mechanism are basically the same as those of the mechanisms in the aforementioned first sheet-making devices 100, so as to respectively realize the correction of the negative electrode sheet 920 roll material, the adjustment of the tension, and the detection of defects.

[0054] It is understood that in this embodiment, by setting the second sheet-making device 200 at least as a second unwinding mechanism 210 and a second cutting mechanism 220, the preparation and processing of the negative electrode sheet 920 is facilitated, so as to further stack the positive electrode sheet 910 and the negative electrode sheet 920.

[0055] Specifically, the first stacking device 300 includes a first robotic arm 310 and a first stacking stage 320. The first stacking stage 320 is located downstream of the first robotic arm 310. The first robotic arm 310 is used to pick up the positive electrode 910 and the negative electrode 920 and stack them on the first stacking stage 320.

[0056] like Figure 1 , Figure 3 and Figure 4As shown in this embodiment, by way of example, the first stacking device 300 may include a first robotic arm 310 for gripping the positive electrode 910 and the negative electrode 920, and a first stacking table 320 for the first robotic arm 310 to press and adhere the positive electrode 910 and the negative electrode 920 together. The first stacking table 320 may be disposed downstream of the aforementioned first cutting mechanism 120 and second cutting mechanism 220, and the first robotic arm 310 may be disposed between the first cutting mechanism 120 and the second cutting mechanism 220 and the first stacking table 320. The first robotic arm 310 can adopt a rotating platform design. When it rotates, it can grasp the positive electrode 910 obtained by the first cutting mechanism 120 and the negative electrode 920 obtained by the second cutting mechanism 220. After grasping the positive electrode 910 and the negative electrode 920 onto the first stacking table 320, it can also press the positive electrode 910 and the negative electrode 920 together.

[0057] like Figure 4 and Figure 5 As shown, in this embodiment, both the positive electrode 910 and the negative electrode 920 can be layered structures. The positive electrode 910 may include a positive current collector layer 911, a positive electrode material layer 912, and a solid electrolyte layer 9121 arranged sequentially, while the negative electrode 920 may include a solid electrolyte layer 9121, a negative electrode material layer 921, and a negative current collector layer 922 arranged sequentially. The solid electrolyte layer 9121 of the positive electrode 910 and the solid electrolyte layer 9121 of the negative electrode 920 can be made of the same material. When the first robotic arm 310 picks up the positive electrode 910 and the negative electrode 920 and places them on the first stacking stage 320 for stacking, the solid electrolyte layer 9121 of the positive electrode 910 can be pressed tightly against and connected to the solid electrolyte layer 9121 of the negative electrode 920, forming an electrical connection.

[0058] It is understood that in this embodiment, the first stacking device 300 is at least configured as a first robotic arm 310 for gripping the positive electrode 910 and the negative electrode 920, and a first stacking stage 320 for the first robotic arm 310 to stack the positive electrode 910 and the negative electrode 920, so as to facilitate the connection between the positive electrode 910 and the negative electrode 920, so as to further prepare the adhesive frame 930 on the positive electrode 910 and the negative electrode 920.

[0059] Specifically, the first adhesive making device 400 includes a first adhesive coating mechanism 410 and a first adhesive fixing mechanism 420. The first adhesive fixing mechanism 420 is located downstream of the first adhesive coating mechanism 410. The first adhesive coating mechanism 410 is used to coat the adhesive frame 930, and the first adhesive fixing mechanism 420 is used to cure the adhesive frame 930.

[0060] like Figure 1, Figure 3 and Figure 4 As shown in this embodiment, by way of example, the first adhesive application apparatus 400 may include a first adhesive application mechanism 410 for coating an adhesive frame 930 on the edge portions of the positive electrode 910 and the negative electrode 920, and a first adhesive curing mechanism 420 for curing the coated adhesive frame 930, wherein the first adhesive application mechanism 410 may be disposed downstream of the first adhesive curing mechanism 420.

[0061] In this embodiment, the first adhesive application mechanism 410 can be an adhesive applicator, which can apply adhesive to the edge portions of the positive electrode 910 and the negative electrode 920 to form an adhesive frame 930. Specifically, the adhesive frame 930 can include a first adhesive frame 931 and a second adhesive frame 932. The first adhesive frame 931 can be disposed on the edge portion of the positive electrode 910 extending along a first direction beyond the negative electrode 920, while the second adhesive frame 932 can be disposed on the edge portion of the negative electrode 920 extending along the first direction beyond the positive electrode 910 and on the edge portion of the negative electrode 920 extending along a second direction beyond the positive electrode 910. Further, the positive electrode 910 can be specifically disposed at the middle position of the negative electrode 920 along the second direction, so that both sides of the negative electrode 920 extend beyond the positive electrode 910 along the second direction. Based on this arrangement, the second frame 932 can be U-shaped, with the two sides of the U-shape of the second frame 932 located on the sides of the negative electrode 920 extending along the first direction beyond the positive electrode 910, and the closed side of the U-shape of the second frame 932 located at the end of the negative electrode 920 extending along the second direction beyond the negative electrode 920. The first frame 931 can be I-shaped, located at the end of the positive electrode 910 extending along the first direction beyond the negative electrode 920, and situated on the open side of the U-shape of the second frame 932. The first adhesive applicator 410 may include a movable and rotatable adhesive dispensing head, and the movement path of the dispensing head before and after rotating can cover the edge portions of the positive electrode 910 and the negative electrode 920, so as to coat the front and back sides of the stacked positive electrode 910 and negative electrode 920 with the first adhesive frame 931 and the second adhesive frame 932 respectively.

[0062] like Figure 1 , Figure 3 and Figure 4 As shown, the structure of the first adhesive curing mechanism 420 can be appropriately selected and set according to the material characteristics of the adhesive frame 930. Its curing method includes, but is not limited to, baking, blowing, ultraviolet light irradiation, etc. For example, the material of the adhesive frame 930 can be ultraviolet light curing (UV) adhesive, and the first adhesive curing mechanism 420 can include an ultraviolet lamp for irradiating the adhesive frame 930 with ultraviolet light.

[0063] In this embodiment, a transfer mechanism 1040 may be provided between the first adhesive coating mechanism 410 and the first adhesive fixing mechanism 420. The transfer mechanism 1040 may be a robotic arm, which can pick up the positive electrode 910 and negative electrode 920 coated with adhesive frame 930 on the first adhesive coating mechanism 410 and transfer them to the first adhesive fixing mechanism 420 so that the first adhesive fixing mechanism 420 can cure the adhesive frame 930.

[0064] It is understood that in this embodiment, by configuring the first adhesive application device 400 at least as a first adhesive coating mechanism 410 for coating the edge portion of the positive electrode 910 and the negative electrode 920 with an adhesive frame 930 and a first adhesive curing mechanism 420 for curing the coated adhesive frame 930, it is convenient to prepare the adhesive frame 930 on the positive electrode 910 and the negative electrode 920 to prepare the desired all-solid-state battery.

[0065] Specifically, the first wafer-making apparatus 100, the second wafer-making apparatus 200, the first stacking apparatus 300, and the first gel-forming apparatus 400 are used to prepare a stacked unit 900 without positive electrode tabs 913 and negative electrode tabs 923. The all-solid-state battery fabrication system also includes:

[0066] The third sheet-making device 500 is located downstream of the first adhesive-making device 400 and is used to prepare a positive electrode sheet 910 with a positive electrode tab 913.

[0067] The fourth sheet-making device 600 is located downstream of the first adhesive-making device 400 and is used to prepare a negative electrode sheet 920 with a negative electrode tab 923.

[0068] The second lamination device 700 is located downstream of the third lamination device 500 and the fourth lamination device 600, and is used to place the positive electrode 910 with positive electrode tab 913 and the negative electrode 920 with negative electrode tab 923 on both sides of at least one lamination unit 900, or to lamination the positive electrode 910 with positive electrode tab 913 and the negative electrode 920 with negative electrode tab 923.

[0069] The second adhesive preparation device 800, located downstream of the second laminating device 700, is used to prepare the adhesive frame 930.

[0070] like Figures 1 to 3As shown in this embodiment, by way of example, the first sheet-making device 100 and the second sheet-making device 200 can be used to prepare a positive electrode sheet 910 without a positive electrode tab 913 and a negative electrode sheet 920 without a negative electrode tab 923, respectively. The first stacking device 300 can be used to stack the positive electrode sheet 910 without a positive electrode tab 913 and the negative electrode sheet 920 without a negative electrode tab 923. The first adhesive-making device 400 can prepare an adhesive frame 930 on the edge portion of the stacked positive electrode sheet 910 without a positive electrode tab 913 and the negative electrode sheet 920 without a negative electrode tab 923 to prepare a stacked unit 900 without a positive electrode tab 913 and a negative electrode tab 923.

[0071] like Figure 1 , Figure 6 and Figure 7 As shown, the preparation system may further include a third sheet-making device 500 for preparing a positive electrode sheet 910 with a positive electrode tab 913, a fourth sheet-making device 600 for preparing a negative electrode sheet 920 with a negative electrode tab 923, a second sheet-stacking device 700 for stacking the positive electrode sheet 910 with the positive electrode tab 910 and the negative electrode sheet 920 with the negative electrode tab 923 on both sides of a stacking unit 900 without the positive electrode tab 913 and the negative electrode tab 923, or for directly stacking the positive electrode sheet 910 with the positive electrode tab 910 and the negative electrode sheet 920 with the negative electrode tab 923, and a second adhesive-making device 800 for preparing an adhesive frame 930 after stacking. The third sheet-making device 500 and the fourth sheet-making device 600 can also be configured as two parallel devices, and can be located downstream of the first glue-making device 400. The second sheet-stacking device 700 can be located downstream of the third sheet-making device 500 and the fourth sheet-making device 600, and the second glue-making device 800 can be located downstream of the second sheet-stacking device 700.

[0072] like Figure 1 and Figure 6 As shown, in this embodiment, the all-solid-state battery may include only one stacked unit 900, and the stacked unit 900 has a positive electrode tab 913 and a negative electrode tab 923.

[0073] At this time, the first sheet-making device 100, the second sheet-making device 200, the first sheet-stacking device 300, and the first glue-making device 400 may not be operating, while only the third sheet-making device 500, the fourth sheet-making device 600, the second sheet-stacking device 700, and the second glue-making device 800 are operating. The third sheet-making device 500 can cut the roll of positive electrode sheet 910 with positive electrode tab 913 into positive electrode sheet 910 with positive electrode tab 913, while the fourth sheet-making device 600 can cut the roll of negative electrode sheet 920 with negative electrode tab 923 into negative electrode sheet 920 with negative electrode tab 923. The second stacking device 700 can directly stack the positive electrode sheet 910 with positive electrode tab 913 and the negative electrode sheet 920 with negative electrode tab 923. The second adhesive-making device 800 can prepare adhesive frames 930 at the edges of the positive electrode sheet 910 with positive electrode tab 913 and the negative electrode sheet 920 with negative electrode tab 923.

[0074] like Figure 1 and Figure 7 As shown, in this embodiment, the all-solid-state battery may also include a plurality of stacked units 900. These stacked units 900 may consist of at least one stacked unit 900 without a positive electrode tab 913 and a negative electrode tab 920 arranged on both sides of the stacked unit 900 without the positive electrode tab 913 and the negative electrode tab 923. The plurality of stacked units 900 of the all-solid-state battery may have an internal series structure, meaning that two adjacent stacked units 900 are directly electrically connected through a positive electrode tab 910 without the positive electrode tab 913 and a negative electrode tab 920 without the negative electrode tab 923. A positive electrode 910 with a positive electrode tab 910 can be connected to a negative electrode 920 without a negative electrode tab 923, and a negative electrode 920 with a negative electrode tab 923 can be connected to a positive electrode 910 without a positive electrode tab 913.

[0075] At this time, the first sheet-making device 100, the second sheet-making device 200, the first sheet-stacking device 300, the first adhesive-making device 400, the third sheet-making device 500, the fourth sheet-making device 600, the second sheet-stacking device 700, and the second adhesive-making device 800 are all operating. The first sheet-making device 100 can cut the roll of positive electrode sheet 910 without positive electrode tab 913 into positive electrode sheet 910. The second sheet-making device 200 can cut the roll of negative electrode sheet 920 without negative electrode tab 923 into negative electrode sheet 920. The first stacking device 300 can stack the positive electrode sheet 910 without positive electrode tab 913 and the negative electrode sheet 920 without negative electrode tab 923. The first adhesive-making device 400 can prepare an adhesive frame 930 on the edge portion of the stacked positive electrode sheet 910 without positive electrode tab 913 and negative electrode sheet 920 without negative electrode tab 923 to prepare a stacked unit 900 without positive electrode tab 913 and negative electrode tab 923. Subsequently, the third sheet-making device 500 can cut the roll of positive electrode sheet 910 with positive electrode tab 913 into positive electrode sheet 910 with positive electrode tab 913, and the fourth sheet-making device 600 can cut the roll of negative electrode sheet 920 with negative electrode tab 923 into negative electrode sheet 920 with negative electrode tab 923. The second stacking device 700 can stack the positive electrode sheet 910 with positive electrode tab 913 and the negative electrode sheet 920 with negative electrode tab 923 on both sides of the stacking unit 900 without positive electrode tab 913 and negative electrode tab 923, and connect the positive electrode sheet 910 with positive electrode tab 913 to a negative electrode sheet 920 without negative electrode tab 923, and connect the negative electrode sheet 920 with negative electrode tab 923 to a positive electrode sheet 910 without positive electrode tab 913. The number of stacked units 900 without positive electrode tabs 913 and negative electrode tabs 923 can be reasonably selected according to actual needs, and there must be at least one. When there are several stacked units 900 without positive electrode tabs 913 and negative electrode tabs 923, two adjacent stacked units 900 are directly electrically connected through a positive electrode 910 without positive electrode tabs 913 and a negative electrode 920 without negative electrode tabs 923. The second adhesive forming device 800 can prepare adhesive frames 930 on the edge portions of the positive electrode 910 with positive electrode tabs 913 and the stacked units 900 without positive electrode tabs 913 and negative electrode tabs 923, as well as on the edge portions of the negative electrode 920 with negative electrode tabs 923 and the stacked units 900 without positive electrode tabs 913 and negative electrode tabs 923.

[0076] like Figure 1As shown, in this embodiment, when the all-solid-state battery includes several stacked units 900, the several stacked units 900 can also be internally parallel structures, that is, each of two adjacent stacked units 900 can have a positive electrode tab 913 and a negative electrode tab 923. The two stacked units 900 are insulated during stacking, and after the insulation treatment, their positive electrode tabs 913 are connected and their negative electrode tabs 923 are connected to achieve parallel connection.

[0077] At this time, the first sheet-making device 100, the second sheet-making device 200, the first sheet-stacking device 300, and the first glue-making device 400 may not be operating, while only the third sheet-making device 500, the fourth sheet-making device 600, the second sheet-stacking device 700, and the second glue-making device 800 are operating. The third sheet-making device 500 can cut the roll of positive electrode sheet 910 with positive electrode tab 913 into positive electrode sheet 910 with positive electrode tab 913, while the fourth sheet-making device 600 can cut the roll of negative electrode sheet 920 with negative electrode tab 923 into negative electrode sheet 920 with negative electrode tab 923. The second stacking device 700 can directly stack the positive electrode sheet 910 with positive electrode tab 913 and the negative electrode sheet 920 with negative electrode tab 923. The second adhesive-making device 800 can prepare an adhesive frame 930 after stacking to obtain a stacked unit 900 with positive electrode tab 913 and negative electrode tab 923. When several lamination units 900 with positive electrode tabs 913 and negative electrode tabs 923 are laminated, an insulating adhesive layer or other structure can be arranged between two adjacent lamination units 900 to achieve insulation between them. This process can be completed by an adhesive application mechanism or manually. After the insulating adhesive layer is arranged, several lamination units 900 with positive electrode tabs 913 and negative electrode tabs 923 can be laminated again. This process can be completed by a second lamination device 700 or by other independently set lamination devices.

[0078] In this embodiment, when the all-solid-state battery includes several stacked units 900, the several stacked units 900 can also be a combination of stacked units 900 without positive electrode tabs 913 and negative electrode tabs 923 and stacked units 900 with positive electrode tabs 913 and negative electrode tabs 923, so that the several stacked units 900 have an internal series-parallel structure, that is, a combination of internal series structure and internal parallel structure. Its preparation method is a combination of the aforementioned preparation methods of all-solid-state batteries with internal series structure and internal parallel structure, which will not be elaborated here.

[0079] It is understood that by setting up the third sheet-making device 500, the fourth sheet-making device 600, the second stacking device 700, and the second gel-forming device 800, this embodiment can directly prepare an all-solid-state battery with positive electrode tab 913 and negative electrode tab 923 without separately preparing the positive electrode tab 913 and negative electrode tab 923, which is more convenient. At the same time, the all-solid-state battery prepared in this embodiment can also include several structural forms, increasing the versatility and functionality of the preparation system.

[0080] More specifically, the third sheet-making apparatus 500 includes a third unwinding mechanism 510 and a third cutting mechanism 520. The third cutting mechanism 520 is located downstream of the third unwinding mechanism 510. The third unwinding mechanism 510 is used to unwind the roll of positive electrode sheet 910 with positive electrode tab 913, and the third cutting mechanism 520 is used to cut the roll of positive electrode sheet 910 with positive electrode tab 913 into positive electrode sheet 910 with positive electrode tab 913.

[0081] like Figure 1 and Figure 8 As shown in this embodiment, by way of example, the positive electrode sheet 910 can be cut from a roll of material. This roll of material can be a roll of positive electrode sheet 910 with positive electrode tabs 913 or a roll of positive electrode sheet 910 without positive electrode tabs 913. The first sheet-making device 100 is used to cut the roll of positive electrode sheet 910 without positive electrode tabs 913 into positive electrode sheet 910 without positive electrode tabs 913, and the third sheet-making device 500 is used to cut the roll of positive electrode sheet 910 with positive electrode tabs 913 into positive electrode sheet 910 with positive electrode tabs 913.

[0082] Similarly, the third sheet-making device 500 may include a third unwinding mechanism 510 for unwinding the roll material and a third cutting mechanism 520 for cutting the unwound roll material, wherein the third cutting mechanism 520 may be located downstream of the third unwinding mechanism 510. The third unwinding mechanism 510 may also include a third roll 511 and a third transfer roller 512, while the third cutting mechanism 520 may specifically be a cutting machine. The roll material with positive electrode tabs 913 and positive electrode sheet 910 may be arranged on the third roll 511 and tensioned between the third roll 511 and the third cutting mechanism 520; while the third transfer roller 512 may be driven by a motor or other drive device, and may be located between the third roll 511 and the third cutting mechanism 520 and in contact with the roll material with positive electrode tabs 913 and positive electrode sheet 910 to drive the roll material with positive electrode tabs 913 to move. Between the third roll 511 and the third cutting mechanism 520, a correction mechanism 1010, a tension control mechanism 1020, and a roll material inspection mechanism 1030 can also be provided.

[0083] It is understood that, by configuring the third sheet-making device 500 as at least the third unwinding mechanism 510 and the third cutting mechanism 520, this embodiment facilitates the preparation and processing of the positive electrode sheet 910 with the positive electrode tab 913.

[0084] More specifically, the fourth sheet-making apparatus 600 includes a fourth unwinding mechanism 610 and a fourth cutting mechanism 620. The fourth cutting mechanism 620 is located downstream of the fourth unwinding mechanism 610. The fourth unwinding mechanism 610 is used to unwind the roll of negative electrode sheet 920 with negative electrode tab 923, and the fourth cutting mechanism 620 is used to cut the roll of negative electrode sheet 920 with negative electrode tab 923 into negative electrode sheet 920 with negative electrode tab 923.

[0085] like Figure 1 and Figure 8 As shown in this embodiment, by way of example, the negative electrode sheet 920 can also be cut from a roll of material. This roll of material can be either a roll of negative electrode sheet 920 with negative electrode tabs 923 or a roll of negative electrode sheet 920 without negative electrode tabs 923. The second sheet-making device 200 is used to cut the roll of negative electrode sheet 920 without negative electrode tabs 923 into negative electrode sheet 920 without negative electrode tabs 923, and the fourth sheet-making device 600 is used to cut the roll of negative electrode sheet 920 with negative electrode tabs 923 into negative electrode sheet 920 with negative electrode tabs 923.

[0086] Similarly, the fourth sheet-making device 600 may include a fourth unwinding mechanism 610 for unwinding the roll material and a fourth cutting mechanism 620 for cutting the unwound roll material, wherein the fourth cutting mechanism 620 may be located downstream of the fourth unwinding mechanism 610. The fourth unwinding mechanism 610 may also include a fourth roll 611 and a fourth transfer roller 612, while the fourth cutting mechanism 620 may specifically be a cutting machine. The roll material with negative electrode tabs 923 and negative electrode sheet 920 may be arranged on the fourth roll 611 and tensioned between the fourth roll 611 and the fourth cutting mechanism 620; while the fourth transfer roller 612 may be driven by a motor or other drive device, and may be located between the fourth roll 611 and the fourth cutting mechanism 620 and in contact with the roll material with negative electrode tabs 923 and negative electrode sheet 920 to drive the roll material with negative electrode tabs 923 to move. Between the fourth roll 611 and the fourth cutting mechanism 620, a correction mechanism 1010, a tension control mechanism 1020, and a roll material inspection mechanism 1030 can also be provided.

[0087] It is understood that, in this embodiment, by configuring the fourth sheet-making device 600 at least as the fourth unwinding mechanism 610 and the fourth cutting mechanism 620, it is convenient to realize the preparation and processing of the negative electrode sheet 920 with the negative electrode tab 923.

[0088] Specifically, the second stacking device 700 includes a second robotic arm 710 and a second stacking stage 720. The second stacking stage 720 is located downstream of the second robotic arm 710. The second robotic arm 710 is used at least to pick up the positive electrode 910 with positive electrode tab 913 and the negative electrode 920 with negative electrode tab 923 and place them onto the first stacking stage 320 for stacking.

[0089] like Figure 1 and Figure 8 As shown in this embodiment, by way of example, the second stacking device 700 may include a first robotic arm 310 for gripping a positive electrode sheet 910 with a positive electrode tab 913, a negative electrode sheet 920 with a negative electrode tab 923, and a stacking unit 900 without positive and negative electrode tabs 913 and 923, and a first robotic arm 310 for directly stacking the positive electrode sheet 910 with the positive electrode tab 913 and the negative electrode sheet 920 with the negative electrode tab 923 or stacking the positive electrode sheet 910 with the positive electrode tab 913 and the negative electrode sheet 920 with the negative electrode tab 923 by the first robotic arm 310, or stacking the positive electrode sheet 910 with the positive electrode tab 913 and the negative electrode sheet 920 with the negative electrode tab 923 by the first robotic arm 310. Positive electrode sheet 910 with positive electrode tab 913 and negative electrode sheet 920 with negative electrode tab 923 are stacked onto the first stacking platform 320 on both sides of the stacking unit 900 without positive electrode tab 913 and negative electrode tab 923. The second stacking platform 720 can be located downstream of the aforementioned third cutting mechanism 520 and fourth cutting mechanism 620, and the second robot arm 710 can be located between the third cutting mechanism 520 and fourth cutting mechanism 620 and the second stacking platform 720. The second robot arm 710 can also adopt a rotating platform design, which can grasp the positive electrode sheet 910 with positive electrode tab 913 obtained by the third cutting mechanism 520 and the negative electrode sheet 920 with negative electrode tab 923 obtained by the fourth cutting mechanism 620 when it rotates. Meanwhile, the second robotic arm 710 can also be positioned between the first adhesive fixing mechanism 420 and the second stacking device 700, so that it can grasp the stacking unit 900 without the positive electrode tab 913 and negative electrode tab 923 on the first adhesive fixing device when rotating. It is easy to see that there can be three second robotic arms 710 to perform the aforementioned three grasping actions respectively; or there can be only one second robotic arm 710 to perform the aforementioned three grasping actions sequentially; this embodiment takes the former as an example.

[0090] like Figure 1 , Figure 6 and Figure 8As shown, during the stacking process, the second robotic arm 710 can perform gripping actions according to the actual processing needs of the all-solid-state battery. For example, when the all-solid-state battery only includes a stacking unit 900 with a positive electrode tab 913 and a negative electrode tab 923, the second robotic arm 710 can sequentially grip a positive electrode sheet 910 with a positive electrode tab 913 and a negative electrode sheet 920 with a negative electrode tab 923 onto the second stacking stage 720 for stacking. The stacking structure of the positive electrode sheet 910 with the positive electrode tab 913 and the positive electrode sheet 910 without the positive electrode tab 913 can be the same, that is, including a positive current collector layer 911, a positive electrode material layer 912, and a solid electrolyte layer 9121 arranged sequentially, and the positive electrode tab 913 can be connected to the positive current collector layer 911. Similarly, the stacked structure of the negative electrode 920 with negative electrode tab 923 and the negative electrode 920 without negative electrode tab 923 can be the same, that is, it includes a solid electrolyte layer 9121, a negative electrode material layer 921 and a negative electrode current collector layer 922 arranged sequentially, and the negative electrode tab 923 can be connected to the negative electrode current collector layer 922. When the second robot arm 710 stacks the positive electrode 910 with positive electrode tab 913 and the negative electrode 920 with negative electrode tab 923, the second robot arm 710 can press and bond the solid electrolyte layer 9121 of the positive electrode 910 with positive electrode tab 913 and the solid electrolyte layer 9121 of the negative electrode 920 with negative electrode tab 923 into a whole, so as to realize the electrical connection between the positive electrode 910 with positive electrode tab 913 and the negative electrode 920 with negative electrode tab 923.

[0091] like Figure 1 , Figure 7 and Figure 8As shown, for example, when the all-solid-state battery includes three stacked units 900 and is internally connected in series, the second robotic arm 710 can first grasp two stacked units 900 without positive electrode tabs 913 and negative electrode tabs 923, and stack these two stacked units 900 without positive electrode tabs 913 and negative electrode tabs 923; during stacking, the two stacked units 900 without positive electrode tabs 913 and negative electrode tabs 923 are connected through a positive electrode 910 without positive electrode tab 913 and a negative electrode 920 without negative electrode tab 923 to achieve series connection. Subsequently, the second robotic arm 710 can grasp another positive electrode 910 with a positive electrode tab 913 and a negative electrode 920 with a negative electrode tab 923, and stack the positive electrode 910 with a positive electrode tab 913 and the negative electrode 920 with a negative electrode tab 923 to both sides of the aforementioned two series-connected stacking units 900; during stacking, the positive electrode 910 with a positive electrode tab 913 is connected to one of the aforementioned two stacking units 900 without a positive electrode tab 913 and a negative electrode tab 923, and the negative electrode 920 with a negative electrode tab 923 is connected to one of the aforementioned stacking units 900 without a positive electrode tab 913 and a negative electrode tab 923.

[0092] It is understood that in this embodiment, the second stacking device 700 is configured with at least a second robotic arm 710 and a second stacking stage 720 for the second robotic arm 710 to perform stacking, so as to facilitate the stacking of the positive electrode 910 with positive electrode tab 913 and the negative electrode 920 with negative electrode tab 923, so as to further realize the preparation of an all-solid-state battery with positive electrode tab 913 and negative electrode tab 923.

[0093] Specifically, the second glue-making device 800 includes a second glue-applying mechanism 810 and a second glue-curing mechanism 820. The second glue-curing mechanism 820 is located downstream of the second glue-applying mechanism 810. The second glue-applying mechanism 810 is used to apply glue to the glue frame 930, and the second glue-curing mechanism 820 is used to cure the glue frame 930.

[0094] In this embodiment, it is exemplarily illustrated that the second coating mechanism 810 can also be a coating machine. Regardless of whether the positive electrode sheet 910 with positive electrode tab 913 and the negative electrode sheet 920 with negative electrode tab 923 are directly stacked or stacked separately to both sides of the stacking unit 900 without positive electrode tab 913 and negative electrode tab 923, the glue frame 930 is arranged in the form of a first glue frame 931 and a second glue frame 932. Similarly, the second coating mechanism 810 can be configured with the same structure as the first coating mechanism 410, that is, it includes a movable and rotatable glue dispensing head, and the movement path of the glue dispensing head before and after rotatability can cover the position where the glue frame 930 needs to be prepared, so as to coat and shape the first glue frame 931 and the second glue frame 932.

[0095] Similarly, the structure of the second adhesive fixing mechanism 820 can be the same as that of the first adhesive fixing mechanism 420, and a transfer mechanism 1040 can also be provided between the second adhesive coating mechanism 810 and the second adhesive fixing mechanism 820. The transfer mechanism 1040 can also be a robotic arm, which can pick up the positive electrode 910 and negative electrode 920 or the positive electrode 910, negative electrode 920 and stacked unit 900 coated with adhesive frame 930 on the second adhesive coating mechanism 810 and put them onto the second adhesive fixing mechanism 820 so that the second adhesive fixing mechanism 820 can cure the adhesive frame 930.

[0096] It is understood that in this embodiment, by configuring the second adhesive application device 800 at least as a second adhesive coating mechanism 810 for coating the adhesive frame 930 and a second adhesive curing mechanism 820 for curing the coated adhesive frame 930, the adhesive frame 930 is facilitated to be formed and molded, so as to obtain the desired all-solid-state battery.

[0097] The implementation principle of the all-solid-state battery fabrication system provided in this application embodiment is as follows:

[0098] First, the structure of the prepared all-solid-state battery is determined. If the all-solid-state battery only includes a stacking unit 900 with a positive electrode tab 913 and a negative electrode tab 923, then the first sheet-making apparatus 100, the second sheet-making apparatus 200, the first stacking apparatus 300, and the first adhesive application apparatus 400 do not operate, while only the third sheet-making apparatus 500, the fourth sheet-making apparatus 600, the second stacking apparatus 700, and the second adhesive application apparatus 800 operate. The third cutting mechanism 520 can cut the roll of positive electrode sheet 910 with positive electrode tab 913 into positive electrode sheets 910 with positive electrode tab 913, and the fourth cutting mechanism 620 can cut the roll of negative electrode sheet 920 with negative electrode tab 923 into negative electrode sheets 920 with negative electrode tab 923. The second robotic arm 710 can sequentially pick up a positive electrode 910 with a positive electrode tab 913 and a negative electrode 920 with a negative electrode tab 923 and place them onto the second stacking stage 720 for stacking. During stacking, the solid electrolyte layer 9121 of the positive electrode 910 with the positive electrode tab 913 can contact and connect with the solid electrolyte layer 9121 of the negative electrode 920 with the negative electrode tab 923, forming an electrical connection. The second adhesive coating mechanism 810 can coat and shape the adhesive frame 930 at the edges of the positive electrode 910 with the positive electrode tab 913 and the negative electrode 920 with the negative electrode tab 923, and the second adhesive curing mechanism 820 can cure the coated adhesive frame 930.

[0099] If the all-solid-state battery can also include several stacked units 900, and the several stacked units 900 are internally connected in series, then the first sheet-making device 100, the second sheet-making device 200, the first stacking device 300, the first adhesive-forming device 400, the third sheet-making device 500, the fourth sheet-making device 600, the second stacking device 700, and the second adhesive-forming device 800 all perform operations. Among them, the first cutting mechanism 120 can cut the roll of positive electrode sheet 910 without positive electrode tab 913 into positive electrode sheet 910, and the second cutting mechanism 220 can cut the roll of negative electrode sheet 920 without negative electrode tab 923 into negative electrode sheet 920. The first robotic arm 310 can sequentially pick up a positive electrode 910 without a positive electrode tab 913 and a negative electrode 920 without a negative electrode tab 923 and place them onto the first stacking stage 320 for stacking. During stacking, the solid electrolyte layer 9121 of the positive electrode 910 without a positive electrode tab 913 can come into contact with and connect to the solid electrolyte layer 9121 of the negative electrode 920 without a negative electrode tab 923, forming an electrical connection. The first adhesive coating mechanism 410 can coat and shape the adhesive frame 930 on the edge portions of the positive electrode 910 without a positive electrode tab 913 and the negative electrode 920 without a negative electrode tab 923, and the first adhesive curing mechanism 420 can cure the coated adhesive frame 930 to prepare a stacked unit 900 without positive electrode tabs 913 and negative electrode tabs 923. Subsequently, the third cutting mechanism 520 can cut the roll of positive electrode sheet 910 with positive electrode tab 913 into positive electrode sheet 910 with positive electrode tab 913, and the cutting mechanism can cut the roll of negative electrode sheet 920 with negative electrode tab 923 into negative electrode sheet 920 with negative electrode tab 923. The second robotic arm 710 can sequentially pick up a positive electrode 910 with a positive electrode tab 913 and a negative electrode 920 with a negative electrode tab 923 and place them on the second stacking stage 720 to stack them on both sides of the stacking unit 900 without positive electrode tabs 913 and negative electrode tabs 923. During stacking, the positive electrode 910 with positive electrode tab 913 is connected to a negative electrode 920 without negative electrode tab 923, and the negative electrode 920 with negative electrode tab 923 is connected to a positive electrode 910 without positive electrode tab 913. There can be several stacking units 900 on the second stacking stage 720 that do not have positive electrode tabs 913 and negative electrode tabs 923. In this case, two adjacent stacking units 900 are directly electrically connected through a positive electrode 910 without a positive electrode tab 913 and a negative electrode 920 without a negative electrode tab 923.The second adhesive coating mechanism 810 can coat and shape the adhesive frame 930 on the edge portions of the positive electrode sheet 910 with positive electrode tab 913 and the stacked unit 900 without positive electrode tab 913 and negative electrode tab 923, and on the edge portions of the negative electrode sheet 920 with negative electrode tab 923 and the stacked unit 900 without positive electrode tab 913 and negative electrode tab 923. The second adhesive curing mechanism 820 can cure the coated adhesive frame 930.

[0100] This application prepares a positive electrode 910 and a negative electrode 920 using a first electrode preparation device 100 and a second electrode preparation device 200, respectively. The positive electrode 910 and the negative electrode 920 are stacked at a designated position using a first stacking device 300, and a glue frame 930 is prepared at a designated position using a first glue preparation device 400. This process can produce the desired all-solid-state battery. The all-solid-state battery allows the stacking unit 900 to be uniformly stressed during isostatic pressing or flat plate pressing, thereby preventing the edges of the positive electrode 910 and the negative electrode 920 from being sheared and thus avoiding edge breakage or powder shedding. Therefore, the all-solid-state battery preparation system provided in this application can meet the processing requirements of all-solid-state batteries.
