Thin strip films are obtained directly through continuous rolling, reducing the need for separate processing lines for positive electrode strips, battery separators, and negative electrode strips, thus integrating the film processing line. At the same time, it reduces processing equipment and processing steps, reduces the generation of intermediate products, and lowers the defect rate of intermediate products, thereby improving and ensuring the processing accuracy and pass rate of the final product.

Obviously, the accompanying drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0020] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] Example 1, refer to Figures 1-4 This is the first embodiment of the present invention, which proposes a solid-state cellless energy storage power supply production system.
[0023] In this embodiment, the production system specifically includes a frame 1, at least two feeders 3, at least two extrusion roller groups 1 4, and extrusion roller group 2 5. In this embodiment, the number of feeders 3 is preferably two, which are used to hold two kinds of electrode raw materials respectively. The number of extrusion roller groups 1 4 is preferably two. Each extrusion roller group 1 4 corresponds to one feeder 3. The extrusion roller group 1 4 includes two corresponding and rotatably arranged rollers 1. The extrusion roller group 2 5 includes two corresponding and rotatably arranged rollers 2.
[0024] In use, the separator roll 2, wound with the battery separator, is installed on the frame 1; the two electrode materials are fed into the two feeders 3 respectively; then the feeders 3 output the electrode materials to the middle of the two rotating rollers 1. The rotating rollers 1 are heated by the built-in heat exchange oil pipes of the prior art, or alternatively by the electric heating wires of the prior art; the electrode materials are thermally extruded by the extrusion roller group 4 to obtain two electrode strips, namely the positive electrode strip and the negative electrode strip; the positive electrode strip and the negative electrode strip are located on both sides of the battery separator; the positive electrode strip, the battery separator, and the negative electrode strip are conveyed in a stacked state to the middle of the two rotating rollers 2, and the positive electrode strip, the battery separator, and the negative electrode strip are initially compounded and extruded by the extrusion roller group 2 to form a thin strip film. Then the thin strip film is conveyed to the subsequent processing steps. Thin strip films are obtained directly through continuous rolling, reducing the need for separate processing lines for positive electrode strips, battery separators, and negative electrode strips, thus integrating the film processing line. At the same time, it reduces processing equipment and processing steps, reduces the generation of intermediate products, and lowers the defect rate of intermediate products, thereby improving and ensuring the processing accuracy and pass rate of the final product.
[0025] Furthermore, a conveyor chain 24, an outer film guide roller 25, and a heating roller 26 are added. The conveyor chain 24 is arranged in a cyclic transmission relative to the frame 1 to transport the electrode strip to the side of the battery separator. The outer film guide roller 25 is rotatably mounted on the frame 1. The heating roller 26 is rotatably mounted on the frame 1, and the conveyor chain 24 is wound around the heating roller 26. In use, there is a conveyor chain 24 on each side of each electrode strip when viewed along the direction of electrode strip movement. In use, the roll of the outer protective film is installed on the outer film guide roller 25. When each roll of outer protective film is used for the first time, the roll end of the outer protective film is moved to below the extrusion roller group 4 by the traction of the conveyor chain 16 and attaches to the flat surface of the electrode strip. The outer protective film can protect the opposite sides of the two electrode strips, preventing damage to the electrode strips from reducing the final product effect or causing failure. The two electrode strips and their corresponding outer protective films are synchronously conveyed to the second extrusion roller group 5 by the extrusion roller group 4 and the two conveyor chains 24, forming an overall five-layer overlapping structure. The five layers are, in order, outer protective film, electrode strip, battery separator, electrode strip, and outer protective film. When the outer protective film and electrode strip pass through the heating roller 26, the heating roller 26 heats and keeps the electrode strip warm, which facilitates the extrusion of the subsequent roller pressing belt 10.
[0026] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention. Based on the first embodiment, this embodiment further adds a third set of extrusion rollers 6 and optimizes the number of feeders 3 and extrusion roller sets 4. Specifically, in this embodiment, the number of feeders 3 is preferably four, in pairs, with each set of feeders 3 corresponding to a type of electrode material; the number of extrusion roller sets 6 is preferably four, with each extrusion roller set 6 corresponding to one feeder 3; the number of extrusion roller sets 4 is preferably two, with each extrusion roller set 4 corresponding to two extrusion roller sets 6.
[0027] In use, the electrode raw materials are conveyed to the extrusion roller group 6 via the feed component 3. The extrusion roller group 6 is heated by the built-in heat exchange oil pipe in the prior art, or by the electric heating wire in the prior art. With the help of the hot extrusion of the extrusion roller group 6, a stable electrode sheet is obtained. Two identical electrode sheets can be obtained for each type of electrode raw material. Then, the two identical electrode sheets are synchronously conveyed to the extrusion roller group 4. With the help of the extrusion roller group 4, an electrode strip is obtained. The adhesion, mixing uniformity and density between the electrode raw materials are improved by the two consecutive hot roller pressing. At the same time, the thickness of the electrode strip is guaranteed, avoiding the problems of poor thickness uniformity and density uniformity that occur when the electrode raw materials are only rolled once, which would cause poor film quality.
[0028] Meanwhile, a width-fixing blade is also rotatably mounted on the stand 1. A width-fixing blade is provided on both sides of any type of electrode strip. The width-fixing blade is used to cut the edges of the electrode strip on both sides to improve the consistency of the electrode strip width.
[0029] Example 3, refer to Figures 1-6 This is the third embodiment of the present invention. Based on the first embodiment, this embodiment further adds a fourth extrusion roller group 7. Specifically, the fourth extrusion roller group 7 includes a fourth roller shaft 8, a fourth transmission roller 9, a roller pressing belt 10, a transmission gear 11, a tensioning shaft 13, and an adjusting member 12. In this embodiment, the number of the fourth extrusion roller group 7 is preferably two, symmetrically distributed on both sides of the diaphragm.
[0030] In this embodiment, the roller pressing belt 10 is preferably made of steel belt, and a roller pressing gap is formed between the two roller pressing belts 10. The roller pressing gap is used for the passage of the film. The distance of the roller pressing gap is less than or equal to the thickness of the film output by the extrusion roller group 5, so that the film can be extruded again by the two roller pressing belts 10, and the film thickness is prevented from rebounding and failing to meet the product size requirements. In use, the diaphragm output from the extrusion roller group 25 is conveyed to the entrance of the roller gap, and the diaphragm is rolled again by the extrusion between the two roller belts 10. During the process, the two roller shafts 48 on both sides of the diaphragm are driven simultaneously by the built-in power source. The roller shafts 48 drive the roller belts 10 to move. The two transmission rollers 49 are synchronously driven by two meshing transmission gears 11 to avoid inconsistent movement speeds of the roller belts 10 on both sides of the diaphragm, which would cause wrinkles on the diaphragm surface and increase the product defect rate. By applying external force to drive the adjusting component 12 to slide on the stand 1, the adjusting component 12 drives the tensioning shaft 13 to slide synchronously and adjust the tension of the roller belts 10 to ensure that the roller belts 10 are in a taut state and to avoid the roller belts 10 becoming loose, which would cause problems such as diaphragm wrinkles and misalignment.
[0031] Meanwhile, a heating unit is installed on the stand 1, employing existing oil heat exchange technology. The heating unit heats the roller 8, which in turn heats the pressing belt 10. Simultaneously, the pressing belt 10 itself generates heat as it circulates through the roller 8, drive roller 9, and the outer ring of the tensioning shaft 13. This further increases the temperature of the pressing belt 10, achieving thermal pressing of the diaphragm and improving the pressing and shaping effects. Furthermore, the symmetrical arrangement of the two pressing belts 10 helps improve the parallelism of the two electrode strips on the diaphragm, enhancing product consistency.
[0032] Example 4, refer to Figures 1-6 and Figure 8This is the fourth embodiment of the present invention. Based on the first embodiment, this embodiment further refines the processing steps of the film. On one side of the stand 1, a cutting assembly 14, a cutting component 15, a compression roller group 7, a packaging assembly 16, and a baking assembly 17 are added sequentially. In this embodiment, the compression roller group 7 is preferably two in number, symmetrically distributed on both sides of the film. The cutting assembly 14 is preferably a laser cutting device in the prior art capable of performing cutting operations. The cutting assembly 15 is preferably any existing device capable of rolling cutting. For example, the specific cutting assembly 15 includes a cutting frame 21, on which an eccentric wheel 22 is rotatably mounted; a lower blade 23 is mounted on the eccentric wheel 22; when the eccentric wheel 22 rotates, the lower blade 23 slides up and down and back and forth relative to the cutting frame 21 (viewed along the direction of film movement); an upper blade is slidably mounted on the cutting frame 21, and the sliding direction of the upper blade is the same as the film conveying direction; when the eccentric wheel 22 rotates, the lower blade 23 gradually approaches the upper blade, and when the lower blade 23 is at its highest point, the lower blade 23 and the upper blade are precisely engaged, cutting the film; the cutting length can be adjusted by adjusting the rotation speed of the eccentric wheel 22. The extrusion roller group 4 7 on one side of the frame 1 is the same as the extrusion roller group 4 7 on the frame 1, which can re-roll and shape the cut film, improving product consistency. The packaging component 16 can be any existing equipment capable of packaging sheet-like products, picking up and loading the continuously output segmented diaphragms into the carrier frame. The baking component 17 can be any existing equipment capable of baking, conveying the products via a circulating conveyor belt; the carrier frame and the diaphragm are placed together on the conveyor belt, and the baking component 17 dehumidifies and shapes the diaphragm. The diaphragm shaping process is completed using the components arranged in sequence above, improving product consistency and yield.
[0033] Example 5, refer to Figures 1-4 and Figure 7 This is the fifth embodiment of the present invention. Based on the first embodiment, this embodiment further refines the feeding component 3 by adding an auger shaft 19 and a feeding pipe 20. In use, the electrode raw material is transported into the feeding chamber 18 through the feeding pipe 20. The rotating auger shaft 19 squeezes the electrode raw material downwards and transports it to the extrusion roller group 4 for rolling. With the help of the downward spiral extrusion of the auger shaft 19 and the falling of the electrode raw material by its own weight, the electrode raw material is compacted and transported, improving the density of the product and avoiding the problem of uneven density and inconsistent energy storage effect.
[0034] Example 6, refer to Figures 1-8 This is the sixth embodiment of the present invention, which proposes a solid-state cellless energy storage power supply processing technology.
[0035] The specific steps include: First, the battery separator and two types of electrode materials are loaded and placed in their corresponding positions. Second, the auger shaft 19 is activated to press the electrode materials downwards between the extrusion roller group 3 and 6, obtaining two types of electrode sheets, namely positive electrode sheets and negative electrode sheets, through the thermal extrusion of the extrusion roller group 3 and 6. There are two sets of each type of electrode sheet. Third, the two sets of electrode sheets with the same electrode are conveyed to the extrusion roller group 4, where they are thermally extruded to obtain two types of electrode strips, namely positive electrode strips and negative electrode strips. Fourth, the positive electrode strips and negative electrode strips are conveyed to both sides of the battery separator, and the whole assembly is conveyed to the extrusion rollers in a stacked manner. In step 5, the initial membrane sheet is initially obtained by hot extrusion using the extrusion rollers in group 2. In step 6, the initial membrane sheet is conveyed between two roller belts 10, and the initial membrane sheet is hot-extruded and shaped by the hot extrusion of the two roller belts 10 to obtain a strip-shaped membrane sheet. In step 7, the membrane sheet is cut on both sides according to the product size requirements, and a membrane sheet with a certain number of notches on the sides is output. In step 8, the membrane sheet is cut into segments of a certain size according to the product size requirements. In step 9, the segmented membrane sheets are sorted and boxed. In step 10, the boxed membrane sheets are baked.
[0036] In specific implementation, the electrode raw material is conveyed to the feed unit 3. The number of feed units 3 is preferably four, in pairs, with each pair corresponding to one type of electrode raw material. In this example, the first rolling is performed using extrusion roller group three 6. The number of extrusion roller group three 6 is preferably four, with each feed unit 3 corresponding to one extrusion roller group three 6. In this example, the second rolling is performed using extrusion roller group one 4. The number of extrusion roller group one 4 is preferably two, with each extrusion roller group one 4 corresponding to two extrusion roller groups three 6.
[0037] The feed unit 3 feeds the two types of electrode raw materials to four extrusion roller groups 36 for the first rolling, resulting in four portions of the two types of electrode sheets. Then, two portions of the same type of electrode sheets are stacked together again and fed to the same extrusion roller group 4 for the second rolling, resulting in positive electrode strips and negative electrode strips respectively.
[0038] In this example, the second extrusion roller group 5 is used for the third rolling process. The positive electrode strip, battery separator and negative electrode strip are stacked in sequence for composite rolling and then conveyed to the second extrusion roller group 5 for the third rolling process to obtain a strip-shaped film.
[0039] In this example, the fourth and fifth rolling processes are performed using extrusion roller group 7. Preferably, there are four extrusion roller groups 7, with two groups set on the frame 1 as the first group and the other two groups located on one side of the frame 1 as the second group. The strip-shaped film is conveyed to the extrusion roller group 7 in the first group for the fourth rolling process. The extrusion roller group 7 is heated by the heating unit set on the frame 1. The heated extrusion roller group 7 is used to perform hot rolling of the film, which is more conducive to film shaping and dehumidification.
[0040] Then, after the fourth rolling, the membrane undergoes side cutting and notching, length cutting, a fifth rolling, sorting and packing, and baking to complete the final product shaping. The fourth and fifth geothermal rolling processes improve the consistency of product dimensions and yield, preventing separation between the positive and negative electrode strips and the battery separator.
[0041] This processing technology enables one-time production of electrode raw materials and separator batteries into membrane sheets, reducing redundancy in intermediate products such as positive and negative electrode strips. It avoids the large-scale production, storage, and transfer of intermediate products, significantly shortening the processing flow and steps. Furthermore, by simultaneously cutting and trimming the positive electrode strip, battery separator, and negative electrode strip, it greatly improves product dimensional consistency, reducing the inconsistency in dimensional accuracy that occurs when intermediate products are cut individually. It also reduces storage, saves production space, and improves the utilization rate of production space. The processing technology described in this embodiment can significantly shorten the membrane processing flow and steps, reduce the amount of intermediate storage and buffer equipment, decrease the occurrence of intermediate products, and facilitate the widespread adoption of this product processing technology.
[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
