Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a dual-electrode integrated substrate. Background Technology

[0002] A battery is a device that can directly convert energy in the form of chemical energy, internal energy, light energy, atomic energy, etc., into electrical energy. Inside a battery, there are two electrodes made of different materials—a positive electrode (also called a cathode) and a negative electrode (also called an anode). These two materials can participate in redox reactions in an electrolyte (such as a liquid, gel, or solid). During the reaction, the positive electrode material accepts electrons and undergoes a reduction reaction; while the negative electrode material releases electrons and undergoes an oxidation reaction. Batteries are widely used in modern society, covering almost all fields that require electrical energy.

[0003] Traditional battery packs consist of multiple independent batteries connected in series and linked by connecting tabs or wires. However, excessive resistance in the connecting parts (such as connecting tabs or wires) can consume too much of the battery's output power. As the resistance increases, the output voltage of the battery pack decreases, thereby reducing the actual usable power and efficiency of the battery. Therefore, a dual-electrode integrated substrate is proposed to solve the above-mentioned problems. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a dual-electrode integrated substrate, including a positive electrode sheet and a negative electrode sheet, with a separator paper disposed between the positive electrode sheet and the negative electrode sheet. A single positive electrode sheet, a single negative electrode sheet, and the separator paper constitute a battery cell. Two adjacent battery cells are stacked vertically, and a connecting layer is disposed between the two battery cells. An insulating pad is disposed at one end of the plurality of battery cells.

[0005] Furthermore, the connecting layer is made of foamed metal material.

[0006] The beneficial effects of this utility model are as follows: This utility model combines positive electrode sheet, negative electrode sheet and separator paper into a single battery cell, and stacks adjacent battery cells one on top of the other, thereby achieving a highly compact and integrated battery structure. A connecting layer is provided between the battery cells, and the connecting layer is made of foam metal material. Foam metal material has good conductivity and can effectively reduce the contact resistance between battery cells, thereby reducing the energy loss of the battery pack during charging and discharging.

[0009] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0010] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0011] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0012] In the embodiments, by Figure 1 Provided is a dual-electrode integrated substrate, comprising a positive electrode 1 and a negative electrode 2, with a separator paper 3 disposed between the positive electrode 1 and the negative electrode 2. Each positive electrode 1, each negative electrode 2, and the separator paper 3 constitute a battery cell. Adjacent battery cells are stacked vertically, with a connecting layer 4 disposed between the two battery cells. An insulating pad 5 is disposed at one end of each of the multiple battery cells. The positive electrode 1, the negative electrode 2, and the separator paper 3 are combined to form a single battery cell. The separator paper 3 serves to isolate the positive and negative electrodes, preventing direct contact and short circuits, while allowing electrical current to pass through. Electrolytes permeate between the two electrodes to support the electrochemical reaction. Multiple cells are arranged in a stacked manner. This stacking structure allows the battery pack to be arranged compactly, improving space utilization and making it easy to increase or decrease the number of cells as needed to adjust the total capacity of the battery pack. The connecting layer 4 has good conductivity and electrically connects the electrodes of adjacent cells together, ensuring that current can be smoothly transmitted between cells. The insulating pad 5 plays a role in electrical isolation, preventing cells from making unexpected contact with external conductors or adjacent cells, ensuring the safety and stability of the battery pack.

[0013] Reference Figure 1 The connecting layer is made of foamed metal material;

[0014] With the above structural design, the foam metal material can be any one of foam copper, foam nickel, etc., which has good conductivity and can ensure that a reliable electrical connection is formed between the positive and negative electrodes of adjacent cells, so that the current can be smoothly transmitted between the cells and meet the current requirements of the battery pack during charging and discharging.

[0015] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
