[0002] With the continuous advancement of technology and the increasing demands of people, battery technology is also constantly evolving. Among them, solid-state batteries are a new type of battery technology that uses a solid electrolyte instead of a liquid electrolyte. Compared with traditional liquid batteries, solid-state batteries have advantages such as higher energy density, faster charging speed, better safety performance, and longer lifespan, and have attracted widespread attention.

[0003] In existing technologies, solid-state batteries generally include a positive electrode, a negative electrode, a solid electrolyte, and a frame. The process requires first cutting the positive and negative electrode sheets, solid electrolyte, and frame into sheets, and then stacking these sheets on a stacking table to form a solid-state battery cell. However, existing solid-state battery manufacturing equipment has low sheet-forming efficiency, which cannot match the stacking efficiency of the stacking process, resulting in low overall equipment production efficiency and an inability to meet capacity requirements. Utility Model Content

[0004] Therefore, it is necessary to provide a solid-state battery wafer fabrication device and solid-state battery preparation equipment that can improve wafer fabrication efficiency and better meet production capacity requirements in order to address the above problems.

[0035] Please see Figures 1 to 4This application provides a solid-state battery fabrication apparatus, including a composite mechanism 10 and a fabrication mechanism 20. The composite mechanism 10 includes an electrode unwinding assembly 11, a frame unwinding assembly 12, and a strip composite assembly 13. The electrode unwinding assembly 11 and the frame unwinding assembly 12 are both arranged upstream of the strip composite assembly 13, and are respectively used to unwind and output electrode strip A and frame strip B to the strip composite assembly 13. Both sides of the electrode strip A are provided with a solid electrolyte layer. The strip composite assembly 13 is used to roll-composite the passing electrode strip A and frame strip B to form a composite strip C. It should be noted that the electrode strip A can be a negative electrode strip; however, in other embodiments it can also be a positive electrode strip, which is not limited here. The frame strip B can be a single-layer frame or a double-layer frame, which is not limited here.

[0036] The electrode fabrication mechanism 20 includes an electrode tab cutting assembly 21 and a cutting assembly 22. The electrode tab cutting assembly 21 is located downstream of the composite material assembly 13 and is used to cut the electrode strip A on the passing composite material strip C to form electrode tabs on the electrode strip A. The cutting assembly 22 is located downstream of the electrode tab cutting assembly 21 and is used to cut the passing composite material strip C to form electrode sheet material D. The electrode sheet material D includes a laminated frame, a solid electrolyte layer, an electrode, and a solid electrolyte layer.

[0037] In this way, the electrode strip A and the frame strip B are combined using the strip composite assembly 13, and then the tab cutting assembly 21 is used to cut the composite strip C to form tabs. Finally, the cutting assembly 22 is used to cut the composite strip C to form the electrode sheet D. This avoids cutting the electrode sheet, solid electrolyte layer and frame separately, which helps to improve the sheet production efficiency and thus improve the overall production efficiency of the machine, so as to better meet the production capacity requirements.

[0038] Specifically, in the embodiment, the adhesive frame unwinding assembly 12 outputs an adhesive frame strip B including a release film B1 and several adhesive frames B2 disposed on the same side of the release film B1, with each adhesive frame B2 arranged sequentially along the length direction of the release film B1.

[0039] The composite mechanism 10 also includes a release film winding assembly 14, which is arranged between the downstream of the tape composite assembly 13 and the upstream of the tab cutting assembly 21, for winding the release film B1 on the composite tape C in the path, so that the composite tape C reaching the tab cutting assembly 21 does not contain the release film B1.

[0040] Furthermore, the release film winding assembly 14 includes a first guide roller 142, a first tension adjusting assembly 143, and a release film winding member 141. The first guide roller 142 is used to wind the release film B1 on the composite strip C. The release film winding member 141 is arranged downstream of the first guide roller 142 and is used to wind the release film B1 on the composite strip C that has passed through the first guide roller 142. The first tension adjusting assembly 143 is arranged between the downstream of the first guide roller 142 and the upstream of the release film winding member 141 and is used to adjust the tension of the release film B1 so that the tension of the release film B1 remains stable, so that the release film winding member 141 can stably wind the release film B1.

[0041] Optionally, the first tension adjustment assembly 143 includes a second guide roller 1431, a third guide roller 1433, and a first moving roller 1432. The second guide roller 1431 is arranged downstream of the first guide roller 142, the third guide roller 1433 is arranged downstream of the second guide roller 1431, the release film winding member 141 is arranged downstream of the third guide roller 1433, and the first moving roller 1432 is movably disposed between the second guide roller 1431 and the third guide roller 1433. Thus, after the release film B1 on the composite strip C separates from the composite strip C at the first guide roller 142, it sequentially passes through the second guide roller 1431, the first moving roller, and the third guide roller 1433, and is then wound up by the release film winding member 141. The first moving roller 1432 can move relative to the second passing roller 1431 and the third passing roller 1433, thereby causing the release film B1 to be tensioned or relaxed, that is, to adjust the tension of the release film B1 and ensure that the tension of the release film B1 remains stable.

[0042] It should be noted that the tension of the release film B1 can be adjusted by means of translation or oscillation, which is not limited here.

[0043] Please continue reading Figure 2 and Figure 4 As shown, in a specific embodiment, the composite mechanism 10 further includes a deviation correction component 17, which is arranged between the downstream of the electrode unwinding component 11 and the upstream of the strip composite component 13. The deviation correction component 17 is used to correct the deviation of the passing electrode strip A, so as to prevent the electrode strip A entering the strip composite component 13 from deviating from the frame strip B in the width direction.

[0044] Specifically, in this embodiment, the composite mechanism 10 further includes a fourth guide roller 161, a first tape-joining assembly 163, and a fifth guide roller 165. The fourth guide roller 161 and the fifth guide roller 165 are both arranged downstream of the electrode unwinding assembly 11 and upstream of the web-correcting assembly 17, and the first tape-joining assembly 163 is arranged between the fourth guide roller 161 and the fifth guide roller 165. Thus, the electrode strip A unwound from the electrode unwinding assembly 11 sequentially passes through the fourth guide roller 161, the first tape-joining assembly 163, the fifth guide roller 165, the web-correcting assembly 17, and the tape composite assembly 13. The fourth guide roller 161 and the fifth guide roller 165 are used to deflect the passing electrode strip A, ensuring that the electrode strip A between the fourth guide roller 161 and the fifth guide roller 165 passes through the first tape-joining assembly 163, so that a tape-joining operation can be performed at the first tape-joining assembly 163.

[0045] It should be noted that when the material roll on the electrode unwinding assembly 11 is used up and needs to be replaced, the electrode material strip A is first cut at the first splicing assembly 163, and the downstream cut end of the electrode material strip A is fixed by the first splicing assembly 163. Then, the empty material roll on the electrode unwinding assembly 11 is removed, and a new full material roll is loaded onto the electrode unwinding assembly 11. The starting end of the material strip on the full material roll is then pulled to the first splicing assembly 163, and bonded to the downstream cut end of the electrode material strip A fixed by the first splicing assembly 163 with adhesive tape, thus completing the splicing.

[0046] In a specific embodiment, the composite mechanism 10 further includes a second tension adjustment component 18. The second tension adjustment component 18 is arranged between the downstream of the electrode unwinding component 11 and the upstream of the correction component 17, and is used to adjust the tension of the electrode strip A so that the tension of the electrode strip A remains stable, so that the electrode strip A enters the strip composite component 13 with a certain tension, which is beneficial to improving the quality of strip composite.

[0047] Optionally, the second tension adjustment assembly 18 includes a sixth guide roller 181, a seventh guide roller 185, and a second motion roller 183. The sixth guide roller 181 is arranged downstream of the electrode unwinding assembly 11, the seventh guide roller 185 is arranged downstream of the sixth guide roller 181, the web guiding assembly 17 is arranged downstream of the seventh guide roller 185, and the second motion roller 183 is movably disposed between the sixth guide roller 181 and the seventh guide roller 185. Thus, the electrode strip A unwound from the electrode unwinding assembly 11 passes sequentially through the sixth guide roller 181, the second motion roller 183, the seventh guide roller 185, and the web guiding assembly 17. The second motion roller 183 can move relative to the sixth guide roller 181 and the seventh guide roller 185, thereby causing the passing electrode strip A to be tensioned or relaxed, that is, to adjust the tension of the electrode strip A and ensure that the tension of the electrode strip A remains stable.

[0048] It should be noted that the tension of the electrode strip A can be adjusted by means of translation or oscillation, which is not limited here.

[0049] Specifically, in this embodiment, the composite mechanism 10 further includes a first dust removal component 191 and a second dust removal component 192. Both the first dust removal component 191 and the second dust removal component 192 are arranged downstream of the electrode unwinding assembly 11 and upstream of the correction assembly 17. The first dust removal component 191 is used to remove dust from one side of the passing electrode strip A, and the second dust removal component 192 is used to remove dust from the other side of the passing electrode strip. Thus, by using the first dust removal component 191 and the second dust removal component 192 to remove dust from both sides of the electrode strip A, dust and other contaminants are avoided from remaining on the surface of the electrode strip A entering the strip composite assembly 13.

[0050] Specifically Figure 2 In the illustrated embodiment, the electrode unwinding assembly 11, the fourth guide roller 161, the first tape joining assembly 163, the first dust removal assembly 191, the fifth guide roller 165, the sixth guide roller 181, the second motion roller 183, the seventh guide roller 185, the second dust removal assembly 192, and the web guiding assembly 17 are arranged sequentially from upstream to downstream. That is, the electrode strip A unwound from the electrode unwinding assembly 11 passes sequentially through the fourth guide roller 161, the first tape joining assembly 163, the first dust removal assembly 191, the fifth guide roller 165, the sixth guide roller 181, the second motion roller 183, the seventh guide roller 185, the second dust removal assembly 192, and the web guiding assembly 17, and then enters the strip composite assembly 13 for composite processing.

[0051] In a specific embodiment, the composite material assembly 13 includes a first composite roller 131 and a second composite roller 133, both of which are rotatable about their own axes. The first composite roller 131 and the second composite roller 133 are arranged parallel to each other and opposite to each other, forming a composite channel through which the electrode strip A and the frame strip B pass. Thus, the first composite roller 131 and the second composite roller 133 jointly compress the electrode strip A and the frame strip B passing between them, causing the electrode strip A and the frame strip B to adhere to each other to form a composite material strip C.

[0052] Furthermore, the strip composite assembly 13 also includes an adjustment assembly 135, which is connected to the second composite roller 133. The adjustment assembly 135 is used to move the second composite roller 133 closer to or further away from the first composite roller 131, thereby adjusting the width of the composite channel and thus adjusting the pressure on the electrode strip A and the frame strip B passing through the composite channel.

[0053] It should be noted that the first electrode strip A and / or the frame strip B have a bonding adhesive. This bonding adhesive can be a pressure-sensitive adhesive or a heat-sensitive adhesive, and is not limited here. The first composite roller 131 and the second composite roller 133 can be room temperature rollers or hot-press rollers, as long as they can achieve the bonding of the electrode strip A and the frame strip B, and are not limited here.

[0054] Please see Figure 3 and Figure 4 As shown in the embodiments of this application, the film-making mechanism 20 further includes a first visual inspection component 24 and a second visual inspection component 25. Both the first visual inspection component 24 and the second visual inspection component 25 are arranged downstream of the release film winding assembly 14 and upstream of the electrode cutting assembly 21, so that the first visual inspection component 24 and the second visual inspection component 25 can respectively perform visual inspection on both sides of the passing composite strip C, that is, perform surface defect detection on both sides of the composite strip C. Thus, if a surface defect is detected in a certain section of the composite strip C, the defective electrode sheet D will be rejected after that section is subsequently cut to form the electrode sheet D. It should be noted that both the first visual inspection component 24 and the second visual inspection component 25 can be cameras.

[0055] In a specific embodiment, the sheet-making mechanism 20 further includes a main drive conveying assembly 23. This main drive conveying assembly 23 is positioned downstream of the tab cutting assembly 21 and upstream of the cutting assembly 22, and is used to pull the composite material strip C towards the cutting assembly 22. Thus, each time the main drive conveying assembly 23 pulls the composite material strip C a certain distance towards the downstream cutting assembly 22, it ensures that the cutting position of the cutting assembly 22 is accurate each time, and that the resulting electrode sheet material D has a consistent size.

[0056] In a specific embodiment, the electrode fabrication mechanism 20 further includes a feeding assembly 26, a third vision inspection assembly 28, and a fourth vision inspection assembly 29. The feeding assembly 26 is located downstream of the cutting assembly 22 and is used to receive the electrode sheet material D formed by cutting the composite strip C by the cutting assembly 22. The third vision inspection assembly 28 and the fourth vision inspection assembly 29 are both arranged on the feeding path of the feeding assembly 26, enabling both the third vision inspection assembly 28 and the fourth vision inspection assembly 29 to perform visual inspection of the electrode sheet material D on the feeding assembly 26.

[0057] Furthermore, the third vision inspection component 28 is used to perform dimensional inspection on the electrode sheet material D on the feeding assembly 26 to determine whether the dimensions of the electrode sheet material D are qualified. The fourth vision inspection component 29 is used to perform surface defect inspection on the electrode sheet material D on the feeding assembly 26 to determine whether surface defects exist in the electrode sheet material D. It should be noted that both the third vision inspection component 28 and the fourth vision inspection component 29 can be cameras.

[0058] Optionally, the conveying assembly 26 is a vacuum belt conveyor. In actual use, firstly, the main drive conveying assembly 23 pulls the composite material belt C a certain distance towards the cutting assembly 22, so that the starting end of the composite material belt C reaches the belt of the conveying assembly 26 and is attracted and fixed on the belt; then, the cutting assembly 22 cuts the composite material belt C. At this time, part of the electrode sheet material D formed by the cutting is attracted and fixed on the belt of the conveying assembly 26. Then, the belt of the conveying assembly 26 moves downstream, thereby driving the electrode sheet material D to move downstream together.

[0059] In a specific embodiment, the electrode fabrication mechanism 20 further includes a third dust removal component 27, which is arranged on the feeding path of the feeding component 26, so that the third dust removal component 27 can remove dust from the electrode sheet material D on the feeding component 26 to ensure that the cleanliness of the electrode sheet material D on the feeding component 26 meets the process requirements.

[0060] Specifically Figure 3 In the illustrated embodiment, the third dust removal component 27, the third visual inspection component 28, and the fourth visual inspection component 29 are arranged sequentially along the feeding direction of the feeding component 26. That is, the electrode sheet D on the feeding component 26 passes through the third dust removal component 27 for dust removal, the third visual inspection component 28 for size inspection, and the fourth visual inspection component 29 for surface defect inspection.

[0061] Based on the above-described solid-state battery fabrication apparatus, this application also provides a method for fabricating solid-state batteries. Please see below. Figure 1 and Figure 5 The solid-state battery fabrication method includes the following steps:

[0062] S10. Unwinding and outputting electrode strip A and frame strip B. Specifically, electrode strip A is unwound and output downstream of the strip composite assembly 13 using electrode unwinding assembly 11, and frame strip B is unwound and output downstream of the strip composite assembly 13 using frame unwinding assembly 12. Electrode strip A has a solid electrolyte layer on both sides, and frame strip B includes a release film B1 and multiple frames B2 disposed on the same side of the release film B1, with each frame B2 arranged sequentially along the length of the release film B1.

[0063] S20. The electrode strip A and the frame strip B are rolled together to form a composite strip C. Specifically, the electrode strip A and the frame strip B are rolled together using the strip composite assembly 13 to form the composite strip C. The composite strip C includes a release film B1, a frame B2, a solid electrolyte layer, an electrode, and a solid electrolyte layer, which are stacked sequentially.

[0064] S30. The release film B1 on the composite strip C is wound up so that the release film B1 is separated from the composite strip C. At this time, the composite strip C includes a frame B2, a solid electrolyte layer, an electrode sheet and a solid electrolyte layer stacked in sequence.

[0065] S40. The composite strip C is cut to form tab A1. Specifically, the composite strip C is cut using the tab cutting assembly 21 to form tab A1.

[0066] S50. The composite strip C is cut to form an electrode sheet D. Specifically, the composite strip C is cut using the cutting component 22, and the cut part is an electrode sheet D, thus completing the sheet making process.

[0067] Thus, the above solid-state battery manufacturing method first combines the electrode strip A and the frame strip B, then cuts the composite strip C to form the tab A1, and then cuts the composite strip C to form the electrode sheet D. This avoids cutting and manufacturing the electrode sheet, solid electrolyte layer and frame separately, which helps to improve the manufacturing efficiency and thus improve the overall production efficiency to better meet the production capacity requirements.

[0068] Furthermore, step S10 also includes: using the first dust removal component 191 and the second dust removal component 192 to remove dust from both sides of the electrode strip A, respectively, to ensure that the cleanliness of the electrode strip A of the strip composite component 13 meets the process requirements.

[0069] Furthermore, step S10 also includes: using the correction component 17 to correct the deviation of the electrode strip A to ensure that the electrode strip A of the strip composite component 13 is aligned with the frame strip B.

[0070] In a specific embodiment, the step between step S30 and step S40 further includes:

[0071] The first visual inspection component 24 and the second visual inspection component 25 are used to perform visual inspection on both sides of the composite strip C.

[0072] In a specific embodiment, the method further includes the following after step S50:

[0073] The electrode sheet material D is received by the material conveying assembly 26 and conveyed downstream. During the conveying process, the electrode sheet material D is dusted by the third dust removal assembly 27, the electrode sheet material D is dimensionally inspected by the third vision inspection assembly 28, and the electrode sheet material D is surface defect inspected by the fourth vision inspection assembly 29.

[0074] Based on the above-described solid-state battery fabrication apparatus, this application also provides a solid-state battery fabrication device. This solid-state battery fabrication device includes a stacking device and the solid-state battery fabrication apparatus as described in any of the above embodiments. The solid-state battery fabrication apparatus is used to fabricate the above-described electrode sheet D. The stacking device is used to stack the electrode sheet D to form a solid-state battery.

[0075] It should be noted that when the electrode in electrode sheet D is a negative electrode, the stacking device is used to stack electrode sheet D and the positive electrode to form a solid-state battery. When the electrode in electrode sheet D is a positive electrode, the stacking device is used to stack electrode sheet D and the negative electrode to form a solid-state battery.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
