Description

Technical Field

[0001] This invention relates to the field of energy storage devices, and more specifically to a flexible stretchable zinc battery and its fabrication apparatus. Background Technology

[0002] With the rapid development of flexible electronics technology, traditional rigid energy storage devices (such as lithium-ion batteries and button batteries) are unable to withstand mechanical deformations such as stretching and bending, making them unsuitable for the application needs of emerging products such as wearable sensors, flexible displays, and smart skin. Flexible, stretchable zinc batteries, with their high theoretical capacity (zinc anode theoretical capacity 1218 mAh / g), high safety (aqueous electrolyte with no risk of combustion or explosion), low cost (abundant zinc resources), and excellent mechanical stretching properties, have become one of the core research directions in the field of flexible energy storage. The core technology lies in the synergistic design of "elastic substrate composite electrode materials," "gel electrolytes," and "elastic encapsulation structures" to achieve stable electrochemical performance (capacity retention ≥80%) even under stretching deformation (typically requiring a stretching rate ≥100%). The precision of the fabrication and assembly of the core components directly determines the final performance and reliability of the battery.

[0003] In the process of zinc battery manufacturing, the "negative electrode-electrolyte-positive electrode" of the zinc battery must be tightly bonded. If the electrolyte size is smaller than the electrode, it will cause the active area of ​​the electrode to be exposed, leading to oxidation of the zinc negative electrode or poor contact between the positive electrode and the electrolyte, reducing the battery capacity. If the electrolyte size is too large, the excess electrolyte is easy to peel off from the electrode during stretching, generating interface bubbles, which will cause the interface impedance to increase by more than 30%. Therefore, the cutting operation of the electrode and the dielectric is particularly important.

[0004] In existing related technologies, the cutting of stretchable electrodes and gel electrolytes is mostly done by hand with scissors or ordinary blades. However, manual operation can easily lead to irregular cutting edges and large dimensional deviations. Summary of the Invention

[0018] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example 1 This embodiment discloses a flexible and stretchable zinc battery fabrication apparatus, such as... Figure 1-5 As shown, it includes a processing table 1, a cutting mechanism 2, and a driving mechanism 3. The processing table 1 is used to place the material to be cut. The cutting mechanism 2 cooperates with the driving mechanism 3. The driving mechanism 3 drives the cutting mechanism 2 to move back and forth in the vertical direction to cut the material, thereby achieving the effect of accurately cutting the material and improving the quality of zinc battery preparation.

[0020] The cutting mechanism 2 includes a horizontal blade 21 and a vertical blade 22. The two horizontal blades 21 and the two vertical blades 22 together form a rectangle, thus forming a specific cutting area. The two horizontal blades 21 are fixedly installed, while the two vertical blades 22 can slide between the two horizontal blades 21. The driving mechanism 3 includes a mounting platform 31 and a first hydraulic cylinder 32. The mounting platform 31 is installed on the top of the processing table 1, and the cylinder body of the first hydraulic cylinder 32 is installed on the mounting platform 31. The first hydraulic cylinder 32 is used to drive the horizontal blades 21 and the vertical blades 22 to reciprocate vertically. The mounting platform 31 and the processing table 1 are connected by a support rod 310. A movable plate 4 is provided below the mounting platform 31, and the support rod 310 passes through the movable plate 4, which can slide up and down along the support rod 310. The push rod of the first hydraulic cylinder 32 is connected to the top of the movable plate 4. When the first hydraulic cylinder 32 works, the push rod pushes the movable plate 4 to move up and down along the support rod 310, thereby driving the horizontal blade 21 and the vertical blade 22 to move up and down for cutting.

[0021] Four support rods 310 are respectively and correspondingly inserted at the four corners of the movable plate 4, which can effectively improve the stability of the movement of the movable plate 4. The bottom of the movable plate 4 is provided with a dovetail-shaped slide groove 41, which extends along the length of the movable plate 4. Two sliders 42 are provided in the slide groove 41. The shape of the sliders 42 is adapted to the slide groove 41, and the outer wall of the sliders 42 fits against the inner wall of the slide groove 41, so they can slide back and forth in the slide groove 41 without falling out of the slide groove 41. A slide seat 43 is provided on the side of the slider 42 that is flush with the groove opening of the slide groove 41. The slide seat 43 is fixedly connected to the slider 42. The vertical blade 22 is installed on the slide seat 43. The bottom of the movable plate 4 is also provided with a pad 44. The horizontal blade 21 is installed on the pad 44. The blade edge of the vertical blade 22 is flush with the blade edge of the horizontal blade 21. This ensures that the blades in all four directions can cut the material at the same time during cutting, improving the cutting quality. Two second hydraulic cylinders 33 are provided at the bottom of the movable plate 4. The push rod of one second hydraulic cylinder 33 is connected to a slide block 43, and the push rod of the other second hydraulic cylinder 33 is connected to another slide block 43. The second hydraulic cylinders 33 can drive the slide block 43 and the vertical blade 22 to slide within the slide groove 41, thereby adjusting the position of the vertical blade 22 to meet the cutting requirements of materials of different sizes. The cutting edges of the vertical blade 22 and the horizontal blade 21 are both located below the second hydraulic cylinders 33, ensuring that the action of the second hydraulic cylinders 33 will not interfere with the cutting action of the horizontal blade 21 and the vertical blade 22.

[0022] Below the movable plate 4 is a lead screw 45. One end of the lead screw 45 is in contact with the inner wall of a vertical blade 22. A bearing seat can be installed on the inner wall of the vertical blade 22, and one end of the lead screw 45 passes through the bearing seat. The other end of the lead screw 45 passes through another vertical blade 22. An electric motor 46 is installed on the outer wall of the other vertical blade 22, which drives the lead screw 45 to rotate. A scraper 47 is sleeved on the lead screw 45, and the scraper 47 is threaded to the lead screw 45. The end of the scraper 47 is in contact with the inner wall of the transverse blade 21. When the lead screw 45 rotates, the scraper 47 moves along the lead screw 45, thereby scraping the material.

[0023] The scraper 47 includes a connecting part 471 and a scraping part 472. The connecting part 471 has a threaded hole 4711 in its center, and a lead screw 45 is adaptedly screwed into the threaded hole 4711. The bottom of the connecting part 471 has a receiving groove 4712, and the scraping part 472 is adaptedly disposed within the receiving groove 4712. An air cushion 473 is provided at the bottom of the receiving groove 4712, and each air cushion 473 is connected to an air pump via an air pipe. Thus, by controlling the opening and closing of the air pump, the air cushion 473 can be adjusted between expanded and contracted states. When the air cushion 473 is in a contracted state, the lower part of the scraping part 472 is located above the cutting edge of the transverse blade 21; when the air cushion 473 is in an expanded state, the lower part of the scraping part 472 is located below the cutting edge of the transverse blade 21. This allows for either scraping the material before cutting it, or cutting the material before scraping it.

[0024] The implementation principle of this embodiment is as follows: A rectangular cutting area is formed by the cooperation of the horizontal blade 21 and the vertical blade 22, enabling precise cutting of materials to the required dimensions. Simultaneously, the position of the vertical blade 22 is adjusted by the second hydraulic cylinder 33 to accommodate materials of different sizes. The cooperation of the lead screw 45 and the scraper 47 achieves accurate control of the material thickness, greatly improving cutting precision and quality, reducing the performance degradation of zinc batteries caused by cutting problems, and enhancing the reliability and stability of zinc battery manufacturing.

[0025] Example 2 This embodiment discloses a flexible and stretchable zinc battery, such as Figure 6 As shown, the flexible and stretchable zinc battery prepared by the above-mentioned apparatus includes an electrolyte 5 and a pair of electrodes 6 inserted in the electrolyte 5. Both the electrolyte 5 and the electrodes 6 can be twisted or stretched.

[0026] Electrolyte 5 is typically a gel-state electrolyte, which possesses good flexibility and stability, maintaining its performance when the battery is stretched or twisted. Electrode 6 can be a composite electrode material with an elastic substrate, such as an active electrode material composited on an elastic polymer substrate, to ensure that electrode 6 maintains good electrochemical performance during deformation. The electrolyte 5 and electrode 6 are coupled in that electrode 6 is inserted into electrolyte 5, forming a complete battery structure.

[0027] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
