Description

Technical Field

[0001] This utility model relates to the field of storage battery technology, and in particular to a storage battery anti-detachment plate. Background Technology

[0002] Storage batteries are a common type of chemical power source, widely used in automobiles, communications, power, and many other fields. During the use of a storage battery, the plates are one of its core components; the performance and stability of the plates directly affect the overall performance and lifespan of the battery.

[0003] In current battery plates, the active materials undergo continuous chemical reactions during charging and discharging, resulting in changes in volume and structure. If the active materials are not firmly attached, they can easily detach from the plates. This leads to a reduction in the effective area of ​​the plates, a decrease in battery capacity, and a shortened battery lifespan. Therefore, this application proposes a battery anti-detachment plate. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a battery anti-detachment plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A battery anti-detachment electrode plate includes an upper electrode plate substrate, a lower electrode plate substrate is fixedly connected to the bottom of the upper electrode plate substrate, and a reaction chamber is provided between the upper electrode plate substrate and the lower electrode plate substrate. The reaction chamber includes a grid frame, a conductive head, a flow guiding hole and an adhesive mesh.

[0007] Preferably, both the upper electrode substrate and the lower electrode substrate have a number of reaction holes on one side of their surfaces.

[0008] Preferably, the upper electrode substrate and the lower electrode substrate are connected by a grid frame, and the grid frame is arranged in an array at equal proportions.

[0009] Preferably, two conductive heads are fixedly disposed on one side of the grid frame, and the flow guide hole is located on the side of the grid frame near the conductive heads and disposed between the two conductive heads.

[0010] Preferably, the adhesive mesh is fixedly disposed inside the grid frame, and the flow guide holes are interconnected with the adhesive mesh.

[0011] Preferably, the adhesive mesh is coated with an active substance, and the surface of the grid frame is also coated with an active substance.

[0012] Preferably, the adhesive mesh has a dense honeycomb array structure, and the honeycomb structure of the adhesive mesh is hollow.

[0013] This utility model has the following beneficial effects:

[0014] 1. In the reaction chamber between the upper and lower electrode substrates, the adhesion mesh has a dense honeycomb array structure with hollow honeycomb structure, which greatly increases the adhesion area of ​​the active material. Compared with traditional electrode plates, this honeycomb design allows the active material to adhere more firmly to the adhesion mesh and the grid frame surface, reducing the shedding of active material during the charging and discharging process of the battery, effectively extending the service life of the electrode plates, and ensuring the stability of battery performance.

[0015] 2. The flow guide holes and the adhesive mesh are interconnected. The hollow structure of the honeycomb adhesive mesh forms an efficient electrolyte flow channel. When the battery is working, the electrolyte can quickly and evenly penetrate to all parts of the adhesive mesh through the flow guide holes, so that the active materials can fully contact the electrolyte, accelerate the electrochemical reaction speed, improve the charging and discharging efficiency of the battery, and thus improve the overall performance and output power of the battery.

[0016] 3. The grid frame is arranged in an array at equal proportions and connects the upper and lower electrode substrates. Together with the fixed conductive heads, it constructs a stable conductive network, ensuring efficient current transmission. At the same time, the honeycomb adhesive mesh not only helps the active material adhere, but its own structure also enhances the overall strength of the electrode, preventing the active material from falling off while improving the electrode's resistance to deformation under complex working conditions, thus enhancing the reliability and durability of the battery electrode.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A battery anti-detachment electrode plate includes an upper electrode plate substrate 1, with a lower electrode plate substrate 2 fixedly connected to the bottom of the upper electrode plate substrate 1. A reaction chamber is provided between the upper electrode plate substrate 1 and the lower electrode plate substrate 2. The reaction chamber consists of a grid frame 4, a conductive head 5, flow guiding holes 6, and an adhesive mesh 7. Several reaction holes 3 are formed on one side of the surfaces of both the upper electrode plate substrate 1 and the lower electrode plate substrate 2. It should be noted that these reaction holes 3 are used for the subsequent flow of electrolyte and the exchange of substances with the external environment, creating conditions for electrochemical reactions.

[0024] The upper electrode substrate 1 and the lower electrode substrate 2 are connected by a grid frame 4, which is arranged in an array at a proportional ratio. It should be noted that this arrangement of the grid frame 4 not only ensures the structural strength of the electrode plate, but also provides a basis for the subsequent installation of the conductive head 5, the flow guiding hole 6, and the adhesive mesh 7.

[0025] Two conductive heads 5 are fixedly mounted on one side of the grid frame 4. A flow guide hole 6 is located on the side of the grid frame 4 near the conductive heads 5 and positioned between the two conductive heads 5. An adhesive mesh 7 is fixedly mounted inside the grid frame 4. The flow guide hole 6 and the adhesive mesh 7 are interconnected. It should be noted that the conductive heads 5 and the grid frame 4 have good electrical conductivity. The flow guide hole 6 is created on the side of the grid frame 4 near the conductive heads 5 and positioned between the two conductive heads 5 using processes such as stamping or cutting. The size and shape of the flow guide hole 6 are designed according to the flow requirements of the electrolyte to ensure smooth electrolyte passage.

[0026] The adhesive mesh 7 has active materials adhered to it, and the surface of the grid frame 4 also has active materials adhered to it. The adhesive mesh 7 has a dense honeycomb array structure, and the honeycomb structure of the adhesive mesh 7 is hollow. It should be noted that, because the adhesive mesh 7 has a dense honeycomb array structure and the honeycomb structure is hollow, the active materials can be evenly attached to the surfaces of the adhesive mesh 7 and the grid frame 4 using processes such as coating or spraying. The large surface area provided by the honeycomb structure enables the active materials to adhere firmly, reducing the phenomenon of falling off during use.

[0027] In this invention, after the electrolyte is injected into the battery, it enters the reaction chamber through the reaction holes 3 on the surfaces of the upper electrode substrate 1 and the lower electrode substrate 2. Because the guide holes 6 are connected to the adhesion mesh 7, and the adhesion mesh 7 has a dense honeycomb array structure with hollow honeycombs, the electrolyte can quickly and evenly penetrate to all parts of the adhesion mesh 7 and around the grid frame 4, providing a material basis for the electrochemical reaction. The active materials adhered to the surfaces of the adhesion mesh 7 and the grid frame 4 come into full contact with the electrolyte, resulting in an electrochemical reaction. At the negative electrode, the active materials lose electrons, which are output outward through the grid frame 4 and the conductive head 5; at the positive electrode, the active materials gain electrons and combine with ions in the electrolyte, completing the entire electrochemical reaction process.

[0028] Furthermore, the honeycomb adhesive mesh 7 increases the attachment area of ​​active materials, allowing more active materials to participate in the reaction and improving power generation efficiency. Electrons generated by the electrochemical reaction are conducted in the conductive network composed of the grid frame 4 and the conductive head 5, forming a current through the external circuit to power the load. The proportionally arranged array of the grid frame 4 and the reasonable setting of the conductive head 5 ensure efficient electron transmission and stable current output. During the electrochemical reaction, the consumed active materials and ions in the electrolyte are continuously replenished and circulated. The electrolyte flows continuously in the channels formed by the hollow honeycomb structure of the adhesive mesh 7 and the flow guide holes 6, carrying away the substances produced by the reaction and bringing in new reactants, maintaining the continuous electrochemical reaction and ensuring stable power generation by the plates.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
