Description

A graphdiyne-modified flexible supercapacitor electrode assembly Technical Field

[0001] This utility model belongs to the field of electrical equipment, and specifically relates to a graphdiyne-modified flexible supercapacitor electrode assembly. Background Technology

[0002] Flexible supercapacitor electrode assemblies are key energy storage components used in flexible electronic devices. Currently, there are several areas for improvement in flexible supercapacitor electrode assemblies. From an energy storage perspective, commonly used electrode materials such as carbon-based materials are insufficient to meet the demands of long-term continuous power supply. To address this, a conventional approach is to introduce pseudocapacitive materials such as metal oxides, but this increases manufacturing complexity and cost. Regarding structural stability, the bonding forces between materials within the electrode sheet are not very strong. After repeated bending and stretching, the internal structure is prone to displacement and deformation, such as poor contact between electrode material particles, leading to increased resistance and decreased capacitance. Stability is generally enhanced by optimizing material ratios and binders, but this may affect the flexibility of the electrode sheet and fails to fundamentally solve the problem of cumulative damage caused by repeated deformation. Therefore, a new structure is needed to address these technical issues. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a graphdiyne-modified flexible supercapacitor electrode assembly, thereby resolving the problems mentioned in the background section.

[0004] This utility model is achieved through the following technical solution: a graphdiyne-modified flexible supercapacitor electrode assembly, comprising: a support assembly and a capacitor assembly, wherein an electrode assembly for connection to a discharge device is mounted on the outer surface of the support assembly, the support assembly includes a support layer and a support outer layer for supporting the capacitor assembly, the support outer layer is mounted on the upper surface of the support layer, and the capacitor assembly is mounted inside the support outer layer, wherein the capacitor assembly includes a functional layer for energy storage and discharge, and a graphdiyne layer and a conductive layer are mounted on the lower surface of the functional layer.

[0005] In a preferred embodiment, the outer edge of the upper surface of the support layer is rectangular and a support outer layer is installed thereon. The length and width of the support layer match the length and width of the support outer layer. The support layer includes a support plate and a honeycomb plate.

[0006] In a preferred embodiment, two support plates are provided, both of which have the same structure. A honeycomb panel is installed between the two support plates. Both the support plates and the honeycomb panel are made of polyethylene terephthalate. In use, the support plates, the support layers of the honeycomb panel, and the support components of the outer support layer provide basic load-bearing capacity. The honeycomb panel, with its unique porous structure, disperses stress with high mechanical efficiency, enhancing the bending and compressive strength of the electrode sheet.

[0007] In a preferred embodiment, the electrode assembly includes a first connecting plate and a second connecting plate. The first connecting plate is connected to an external power supply device through electrode points, and the first connecting plate is electrically connected to a support assembly through the second connecting plate.

The graphyne layer has good flexibility, and when combined with a support layer, it can maintain structural stability when the electrode sheet is bent, significantly enhancing the cycle life and overall performance of the supercapacitor.

[0009] In a preferred embodiment, a conductive layer is mounted on the lower surface of the fiber layer, and the lower surface of the conductive layer is connected to the upper surface of the support layer.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a support component, the support component includes a support layer for supporting the capacitor component and a support outer layer. The support outer layer is installed on the upper surface of the support layer. The support layer includes a support plate and a honeycomb plate. In use, the support plate, the support layer of the honeycomb plate, and the support outer layer of the support component provide basic load-bearing capacity. The honeycomb plate, with its unique porous structure, disperses stress with high mechanical efficiency, enhancing the bending and compressive strength of the electrode sheet. At the same time, the support outer layer further buffers external impacts and protects the internal capacitor component. The combination of the three allows the electrode sheet to have excellent mechanical stability, electrochemical performance, and environmental adaptability, which can meet the needs of wearable devices, flexible electronics, and other scenarios.

[0011] 2. By setting up a capacitor assembly, the capacitor assembly is installed inside the outer support layer. The capacitor assembly includes a functional layer for energy storage and discharge. A graphdiyne layer and a conductive layer are installed on the lower surface of the functional layer. In use, the graphdiyne layer in the capacitor assembly can reduce the internal resistance of the electrode due to its excellent conductivity, so as to achieve rapid charging and discharging, thereby increasing the specific capacitance. At the same time, the graphdiyne layer has good flexibility. When combined with the support layer, it can maintain structural stability when the electrode sheet is bent, which significantly enhances the cycle life and overall performance of the supercapacitor.

[0023] There are two support plates 211, and the two support plates 211 have the same structure. A honeycomb panel 212 is installed between the two support plates 211. The support plates 211 and the honeycomb panel 212 are both made of polyethylene terephthalate.

[0024] In use, the functional layer 300, graphdiyne layer 330, fiber layer 340, and conductive layer 320 are all mounted on the upper surface of the support layer 210, and are disposed inside the outer support layer 200.

(To be elaborated further), the support plate 211 and the support layer 210 of the honeycomb plate 212, as well as the support components of the outer support layer 200, provide basic load-bearing capacity during use. The honeycomb plate 212, with its unique porous structure, disperses stress with high mechanical efficiency, enhancing the electrode sheet's resistance to bending and compression. Meanwhile, the outer support layer 200 further buffers external impacts and protects the internal capacitor components. The combination of these three components gives the electrode sheet excellent mechanical stability, electrochemical performance, and environmental adaptability, meeting the needs of wearable devices, flexible electronics, and other scenarios.

[0025] Please refer to Figures 1 to 4 as the second embodiment of this utility model: Based on the description in the above embodiments, the electrode assembly further includes a first connecting plate 100 and a second connecting plate 120.

Then, the graphyne layer 330 transfers the energy to the functional layer 300 for energy storage and discharge operations. Since the graphyne layer 330 is set in the capacitor assembly, its excellent conductivity can reduce the internal resistance of the electrode and achieve rapid charging and discharging, thereby increasing the specific capacitance.

When combined with the support layer 210, it can maintain structural stability when the electrode sheet is bent, which significantly enhances the cycle life and overall performance of the supercapacitor.
