A new type of nickel mesh

Abstract

This invention provides a novel nickel mesh, belonging to the field of nickel mesh technology. It includes a first mesh surface and a second mesh surface. The first mesh surface comprises a nickel wire woven mesh surface, which is composed of first nickel wire and second nickel wire. The second mesh surface comprises a woven mesh surface, which is formed by interlacing woven mesh threads. This invention covers the surface of the nickel wire woven mesh surface with a layer of regular woven mesh threads. The regular grid design of the mesh structure of the woven mesh threads can evenly distribute external forces, reduce local stress concentration, thereby improving the fatigue resistance and long-term stability of the material. Furthermore, the regular pores of the mesh structure provide more uniform flow channels, reducing turbulence and pressure drop during fluid flow. Simultaneously, traditional uneven surfaces are prone to local blockage due to particle accumulation, while the uniform pore size design of the regular mesh can reduce dead angles and extend the cleaning cycle.

Description

Technical Field

[0001] This utility model relates to the field of nickel wire mesh technology, and in particular to a novel nickel wire mesh. Background Technology

[0002] Alkaline water electrolysis for hydrogen production is currently a relatively mature method. The alkaline water electrolysis device is an electrolyzer, mainly composed of a strongly alkaline electrolyte, porous cathodes / anodes, and a diaphragm. Currently, the widely used anode material is nickel mesh, and the cathode material is coated nickel mesh. Existing nickel mesh forming methods typically involve weaving nickel wire of a specific diameter (commonly 0.19 / 0.25 mm) into nickel meshes of different mesh counts as the anode material, and coated nickel mesh as the cathode material. The quality of the electrodes determines the voltage and energy consumption of the water electrolyzer, affecting the cost. The evaluation of industrial water electrolysis electrode materials focuses on service life and water electrolysis energy consumption.

[0003] In the traditional design of nickel mesh, an uneven surface morphology includes the following defects:

[0004] Uneven pore distribution:

[0005] Uneven structures can easily create random pores (pore size differences can reach ±30%), which can cause turbulence and local pressure drops when fluid passes through (such as pressure loss increasing by more than 40% in filtration scenarios), thus reducing system energy efficiency.

[0006] Insufficient mechanical strength:

[0007] Stress concentration in raised or recessed areas can easily lead to fatigue cracks over long-term use (especially in high-temperature or corrosive environments), shortening material life (typically reduced by 30% to 50%).

[0008] Uneven coverage of functional coating:

[0009] In catalytic or battery electrode applications, uneven surfaces lead to uneven loading of active materials (such as Pt catalysts or LiCoO2) (deviation rate > 15%), affecting conductivity and reaction efficiency.

[0010] The manufacturing process is complex.

[0011] Relying on multi-step stamping or chemical etching processes, the yield is low (approximately 85%), and it is difficult to achieve micron-level precision control (e.g., aperture error > ±10μm).

[0012] Therefore, this application provides a novel nickel mesh to meet the requirements. Utility Model Content

[0013] The technical problem to be solved by this invention is to provide a new type of nickel mesh to solve existing problems.

[0014] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0015] A novel nickel wire mesh includes: a first mesh surface and a second mesh surface, wherein the first mesh surface includes a nickel wire woven mesh surface composed of a first nickel wire and a second nickel wire, and the second mesh surface includes a woven mesh surface formed by interlacing woven mesh wires.

[0016] Preferably, multiple first and second nickel wires are arranged between the nickel wire woven mesh, and the multiple first and second nickel wires are arranged in an alternating pattern.

[0017] Preferably, the braided mesh is arranged in an interlaced grid pattern inside the braided mesh surface, and the grid of the braided mesh is arranged in a diamond shape.

[0018] Preferably, the nickel wire braided mesh surface is fixedly connected to the braided mesh surface, and the nickel wire braided mesh surface is fixedly connected to the braided mesh surface by welding, and the braided mesh wire is located above the first nickel wire and the second nickel wire, and the surface of the braided mesh wire is covered with a nano-coating.

[0019] Preferably, the nano-coating on the surface of the braided wire is made of CVD-deposited graphene.

[0020] Compared with the prior art, this utility model has at least the following beneficial effects:

[0021] In the above scheme, by covering the surface of the nickel wire braided mesh with a regular braided mesh, the regular grid design of the mesh structure can evenly disperse external forces and reduce local stress concentration, thereby improving the fatigue resistance and long-term stability of the material. In addition, the regular pores of the mesh structure can provide more uniform flow channels, reducing turbulence and pressure drop when the fluid passes through. Meanwhile, traditional uneven surfaces are prone to local blockage due to particle accumulation, while the uniform pore size design of the regular mesh can reduce dead corners and extend the cleaning cycle. The continuous conductive network of the mesh structure can optimize the electron transport path, and the regular mesh surface is more likely to achieve uniform coverage of coatings or catalysts.

Detailed Implementation

[0029] The present invention provides a novel nickel mesh in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments; other alternative methods may be used by those skilled in the art. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0030] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0031] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0032] It is understood that the meanings of “on”, “above”, and “above” in this disclosure should be interpreted in the broadest sense, such that “on” means not only “directly on” something, but also includes something with an intermediary feature or layer, and that “above” or “above” means not only “on” something, but also includes something “above” or “above” without an intermediary feature or layer.

[0033] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0034] like Figures 1 to 3 As shown, an embodiment of the present invention provides a novel nickel mesh, comprising: a first mesh surface 1 and a second mesh surface 2. The first mesh surface 1 includes a nickel wire woven mesh surface 101, which is composed of a first nickel wire 102 and a second nickel wire 103. The second mesh surface 2 includes a woven mesh surface 201, which is formed by interlacing woven mesh wires 202.

[0036] In this embodiment, it should be further explained that the braided mesh 202 is arranged in a grid pattern inside the braided mesh surface 201. The grid of the braided mesh 202 is arranged in a diamond shape. The regularly intersecting diamond grid structure can significantly improve the overall rigidity, especially in high temperature or corrosive environments where it is more resistant to deformation. Moreover, the regular pores of the mesh structure can provide a more uniform flow channel, reducing turbulence and pressure drop when the fluid passes through. At the same time, traditional uneven surfaces are prone to local blockage due to particle accumulation, while the uniform pore size design of the regular mesh can reduce dead corners and extend the cleaning cycle. The continuous conductive network of the mesh structure can optimize the electron transmission path, and the regular mesh surface is more likely to achieve uniform coverage of coatings or catalysts.

[0037] In this embodiment, it should be further explained that the nickel wire braided mesh 101 is fixedly connected to the braided mesh 201, and the nickel wire braided mesh 101 and the braided mesh 201 are fixedly connected by welding. The braided mesh 202 is located above the first nickel wire 102 and the second nickel wire 103. The surface of the braided mesh 202 is covered with a nano-coating. By covering the surface of the nickel wire braided mesh 101 with a layer of regular braided mesh 202, the regular grid design of the mesh structure of the braided mesh 202 can evenly disperse external forces, reduce local stress concentration, and thus improve the fatigue resistance and long-term stability of the material.
