Description

Technical Field

[0001] This utility model relates to the field of electrode design technology, and in particular to an assembly structure for an integrated positive and negative electrode plate. Background Technology

[0002] Integrated positive and negative plates are electrode structure components in batteries (such as lead-acid batteries) that integrate positive and negative active materials with current collectors in a single design or encapsulation. Their core feature is that they break away from the traditional separation of positive and negative plates and use specific processes (such as composite coating and lamination integration) to distribute the positive and negative electrode materials in an orderly manner on the same substrate or frame. They also work with a separator to achieve ion conduction and electronic insulation, thereby simplifying the internal structure of the battery.

[0003] A storage battery is assembled by connecting several integrated positive and negative plates in parallel. After assembly, the positive or negative terminals of several plates need to be connected together. Since the positive and negative terminals of the existing positive and negative plates are distributed at the top and bottom of the tube array, the same electrode of a single positive and negative plate is connected in parallel through the tube array, and the positive and negative terminals are arranged alternately through two sets of tube arrays. This alternately arranged assembly method is inefficient. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an integrated positive and negative electrode plate assembly structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an assembly structure for an integrated positive and negative electrode plate, comprising several tubes arranged horizontally, the tubes being composed of several single tubes, two sheaths being provided at the top of the tubes, the two sheaths being symmetrically arranged on both sides of the tubes, an electrode contact being installed at one end of the sheath, through which current is conducted, a copper busbar being provided above the top of the sheath, several electrode contacts being arranged on the same side according to polarity, and the copper busbar being electrically connected to the electrode contacts of the same electrode on the same side.

[0006] Preferably, the single tube is a hollow structure with both ends connected, and a bottom plate is provided at the bottom end of the tube.

[0007] Preferably, the bottom surface of the sheath is fixedly connected with lead reinforcing bars, which extend from the top end of the single tube to the bottom end.

[0008] Preferably, the position of the lead reinforcing strip corresponds one-to-one with the arrangement position of the single tube, and the outer layer of the lead reinforcing strip is coated with an active substance.

[0009] Preferably, the active material used for the positive electrode is lead dioxide, capacitor-grade activated carbon, and barium sulfate, and the active material used for the negative electrode is elemental lead powder and carbon materials, etc. The active materials are respectively filled in a single tube, and current conduction is achieved through lead reinforcing bars.

[0010] Preferably, an isolation plate is provided between the two sheaths to isolate and prevent short circuits between the positive and negative electrodes.

[0011] Preferably, the bottom plate and the sheath are fixedly connected by an elastic rubber ring.

[0012] Preferably, the bottom end of the copper busbar is provided with a plurality of bending platforms, the spacing of which corresponds to the spacing of the electrode contacts.

[0013] Preferably, the bending table is designed as a bending plate, and the groove formed by the bending table and the copper busbar is used to form a fastening with the electrode contacts.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. Compared to existing traditional single-sided electrode plates that require staggered positive and negative plates and gaps between tubes of the same polarity for insertion of tubes of the other polarity, this utility model separates the positive and negative electrodes on both sides of the tube to form an integrated design. During longitudinal assembly, there is no need to control the assembly gap, which significantly shortens assembly time and reduces the spacing between tubes, thus saving considerable space occupied by the positive and negative plates after assembly. Furthermore, while existing structures have limited capacity adjustment, this structure allows for flexible adjustment of the number of tubes according to actual voltage requirements, easily increasing battery capacity and adapting to more application scenarios.

[0016] 2. In this utility model, the thickness of the lead reinforcing bars and the thickness of the single tube can be selected as needed. The thinner lead reinforcing bars, combined with multiple active materials, are suitable for electrical energy storage, while the thicker single tube is suitable for high-current discharge, adapting to different application requirements. At the same time, with the help of the interlocking and welding structure of the bending table and the copper busbar, several rows of tubes can be quickly connected in parallel to the same electrode, and charging and discharging can be carried out simply by clamping the two ends of the electrode plate with the container, which is convenient to operate and improves the overall flexibility and practicality of use.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an assembly structure for an integrated positive and negative electrode plate, including several tubes 1, each tube 1 being formed by several single tubes 10 arranged horizontally. Two sheaths 3 are provided at the top of the tubes 1, and the two sheaths 3 are symmetrically arranged on both sides of the tubes 1. An electrode contact 4 is installed at one end of the sheath 3, through which current is conducted. A copper busbar 7 is provided above the top of the sheath 3. Several electrode contacts 4 are arranged on the same side according to polarity, and the copper busbar 7 is electrically connected to the electrode contacts 4 of the same electrode on the same side.

[0025] The specific setup and function of this embodiment will be described in detail below. The integrated positive and negative plates combine the electrodes of the prior art and are distributed on both sides of the tube array 1, saving the space occupied by the plates. Since the number of electrodes on a single positive and negative plate is limited, the number of tube arrays 1 is increased according to the actual usage requirements and the voltage of the positive and negative plates. Several tube arrays 1 are assembled vertically to increase the capacity of the battery. Refer to the attached diagram. Figure 3 and attached Figure 4 As shown in the upper half of the figure, in a traditional electrode plate, the electrodes are arranged on one side, with positive and negative electrode plates alternately arranged. Electrodes of the same polarity are connected by copper busbars 7, and gaps are left between tubes 1 of the same polarity to allow insertion of tubes 1 of the other polarity; see attached figure. Figure 3 and attached Figure 4 As shown in the lower half of the figure, the direct mounting of the integrated electrode plate of this positive and negative plates is longitudinally assembled. There is no need to control the assembly gap, so the gap of the tube 1 can be controlled to be small during assembly, which shortens the assembly time and saves the space occupied by the positive and negative plates after assembly.

[0026] Example 2: Figure 1 and Figure 2As shown, the single tube 10 is a hollow structure with both ends open, and a bottom plate 2 is provided at the bottom end of the tube 1. Lead reinforcing bars 6 are fixedly connected to the bottom surface of the sheath 3, and the lead reinforcing bars 6 extend from the top end of the single tube 10 to the bottom end. The position of the lead reinforcing bars 6 corresponds one-to-one with the arrangement of the single tubes 10, and the outer layer of the lead reinforcing bars 6 is wrapped with active material.

[0027] The active materials used for the positive electrode are lead dioxide, capacitor-grade activated carbon, and barium sulfate, while the active materials used for the negative electrode are elemental lead powder and carbon materials. These active materials are respectively filled into the single tube 10, and current conduction is achieved through lead reinforcing bars 6. An isolation plate 5 is installed between the two sheaths 3 to prevent short circuits between the positive and negative electrodes. The bottom plate 2 and the sheaths 3 are fixedly connected by an elastic rubber ring.

[0028] The bottom end of the copper busbar 7 is provided with several bending platforms 8, the spacing of which corresponds to the spacing of the electrode contacts 4. The bending platforms 8 are designed as bending plates, and the grooves formed by the bending platforms 8 and the copper busbar 7 are used to engage with the electrode contacts 4.

[0029] The overall effect of this embodiment is that, due to its electrochemical properties, the thinner the lead rib 6, the more active material is added, and the more electricity is stored, making it suitable for power storage. The thicker the single tube 10 used, the more suitable it is for high-current discharge. When needed, it can be charged and discharged as long as a container clamps both ends of the electrode plate. Several single tubes 10 are arranged in order, with one side being the positive electrode sheath 3 and the other side being the negative electrode sheath 3. The two sheaths 3 are separated by an isolation plate 5, achieving the effect of integrated assembly of positive and negative electrodes. The bending table 8 is welded to the bottom of the copper busbar 7 using an electric welding process. Since the bending table 8 is designed in a bent shape, it forms a groove with one side opening with the copper busbar 7 above. The thickness of the groove corresponds to the thickness of the electrode contact 4, which can clamp the end of the electrode contact 4 between the copper busbar 7 and the bending table 8. The electrode contact 4 is electrically connected to the copper busbar 7 above, which can connect the same electrode of several tubes 1 in parallel.

[0030] The device's operation and working principle are as follows: Several tubes 1, each composed of horizontally arranged single tubes 10, are longitudinally assembled. A bottom plate 2 is installed at the bottom of each tube 1, and sheaths 3 are symmetrically arranged on both sides of the top. Electrode contacts 4 are installed at one end of each sheath 3, with positive and negative electrodes arranged on the same side. An isolation plate 5 is installed between the two sheaths 3 to prevent short circuits. Lead reinforcing bars 6 are fixed to the bottom surface of each sheath 3, corresponding to the positions of the single tubes 10 and wrapped with active materials, including lead dioxide (positive electrode), capacitor-grade activated carbon and barium sulfate, and elemental lead powder and carbon materials (negative electrode). A single tube 10 is filled with a reactive material, and lead reinforcing bars 6 facilitate current conduction. A bending platform 8 is provided at the bottom of the copper busbar 7, the spacing of which corresponds to the spacing of the electrode contacts 4. The bending platform 8 and the copper busbar 7 form a groove to engage the electrode contacts 4. The tubes are fixed by electric welding, so that the same electrode of several tubes 1 is electrically connected to the copper busbar 7 through the electrode contacts 4 to achieve parallel connection, thereby completing charging and discharging. This structure does not require control of assembly gaps, saving space and assembly time. The number of tubes 1 can also be increased or decreased according to voltage requirements to increase battery capacity.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
