[0002] A lithium-ion battery is a secondary battery (rechargeable battery), which mainly works by the movement of lithium ions between the positive electrode and the negative electrode. During the charge and discharge process, Li+ is embedded and de-embedded back and forth between the two electrodes: during charging, Li+ de-embeds from the positive electrode, passes through the electrolyte and embeds into the negative electrode, and the negative electrode is in a lithium-rich state; during discharging, the opposite occurs. Lithium-ion batteries have the advantages of high voltage, high specific energy, long cycle life, good safety performance, low self-discharge, and fast charging speed, and are widely used.

[0003] Now, due to environmental protection requirements, many electronic products need the batteries inside them to be easily disassembled for separate recycling of the electronic products themselves and the batteries. Based on this, the present invention provides a lithium-ion battery with a transfer board and an installation process for the transfer board to achieve the purpose of facilitating the disassembly of the lithium-ion battery inside the electronic product. Summary of the Invention

[0004] Based on this, the present invention provides a lithium-ion battery with a transfer board and an installation process for the transfer board, including a lithium-ion battery body. The lithium-ion battery body is cylindrical, and its positive electrode tab and negative electrode tab are located at the same end of the lithium-ion battery body and are cylindrical. The positive electrode tab and the negative electrode tab are arranged parallel to the axis of the lithium-ion battery body, and the positive electrode tab and the negative electrode tab are symmetrically arranged about the axis center of the lithium-ion battery; the end of the lithium-ion battery with the positive electrode tab and the negative electrode tab is also covered with a transfer board. The transfer board is disc-shaped, the transfer board is coaxially arranged with the lithium-ion battery, and the diameter of the transfer board is the same as the diameter of the lithium-ion battery body; a first conductive layer is covered on the end of the transfer board away from the lithium-ion battery. The first conductive layer includes an annular negative conductive area and a circular positive conductive area. The negative conductive area is coaxially arranged with the transfer board, the positive conductive area is located inside the negative conductive area and is coaxially arranged with the negative conductive area. There is a gap between the positive conductive area and the negative conductive area, forming a first insulating area on the surface of the transfer board; a positive electrode jack and a negative electrode jack penetrating the transfer board are provided in the first insulating area. The positive electrode tab and the negative electrode tab are respectively inserted into the positive electrode jack and the negative electrode jack, and are respectively conducted with the positive conductive area and the negative conductive area through a conduction structure arranged in the first insulating area, and the positive electrode tab and the negative electrode tab are respectively located inside the positive electrode jack and the negative electrode jack.

[0005] In the present invention, a transfer board is provided at one end of the lithium-ion battery having tabs, and the positive tab and the negative tab of the lithium-ion battery are respectively electrically connected to the positive conductive area and the negative conductive area on the transfer board through a conduction structure. Therefore, the positive contact and the negative contact of the lithium-ion battery are transferred to the surface of the transfer board, specifically the positive conductive area and the negative conductive area. Therefore, when the lithium-ion battery of the present invention is in use, only the battery installation structure of the electronic product needs to be adaptively improved, so that the lithium battery of the present invention can be installed and used like a dry battery, thereby achieving the purpose of convenient disassembly of the lithium-ion battery in the electronic product. Among them, the adaptive improvement structure of the electronic product is specifically: contacts matching the positive conduction area and the negative conduction area are provided at the battery installation structure of the electronic product, so that after the lithium-ion battery of the present invention is installed, the positive conduction area and the negative conduction area thereon are respectively abutted against and electrically connected to the corresponding contacts on the electronic product.

[0006] Further, the conduction structure includes a positive conductive ring and a negative conductive ring provided in the first insulating area, and the positive conductive ring and the negative conductive ring respectively surround the positive jack and the negative jack; the conduction structure further includes a second conductive layer provided on the inner side walls of the positive jack and the negative jack, and the second conductive layers located in the positive jack and the negative jack are respectively connected to and conduct the positive conductive ring and the negative conductive ring, and the positive conductive ring and the negative conductive ring are respectively connected to and conduct the positive conductive area and the negative conductive area through a third conductive layer provided on the first insulating area.

[0007] In the present invention, the conduction structure includes a second conductive layer provided in the positive jack and the negative jack, and a positive conductive ring and a negative conductive ring surrounding the positive jack and the negative jack, and the second conductive layers located in the positive jack and the negative jack are respectively connected to and conduct the positive conductive ring and the negative conductive ring. Therefore, the positive tab and the negative tab inserted into the jacks can be conducted through the second conductive layer with the positive conductive ring and the negative conductive ring, and further conduct the positive conductive area and the negative conductive area.

[0008] Further, the tops of the positive tab and the negative tab are fixedly provided on the inner side walls of the positive jack and the negative jack through a soldering structure, and the soldering structure is located inside the positive jack and the negative jack.

[0009] In the present invention, the tops of the positive tab and the negative tab are welded in the positive jack and the negative jack through a soldering structure. Therefore, the transfer board can be fixed on the lithium-ion battery through this soldering structure to realize the fixation of the transfer board and the lithium-ion battery. At the same time, the soldering structure has conductivity, which can ensure the conduction between the positive tab and the negative tab and the positive jack and the negative jack.

[0010] Further, a fourth conductive layer is also provided on the side of the adapter board facing the lithium-ion battery. The fourth conductive layer includes a first region and a second region, and there is a gap between the first region and the second region, forming a second insulating region on the surface of the adapter board; the second insulating region is located between the positive electrode jack and the negative electrode jack, and the second conductive layers in the positive electrode jack and the negative electrode jack are respectively connected and conduct the first region and the second region.

[0011] In the present invention, the materials of the first conductive layer, the second conductive layer, the third conductive layer, and the fourth conductive layer are preferably copper metal, and can be processed on the surface of the adapter board through the processes of electroless copper plating and electroplating. Specifically, the first conductive layer, the second conductive layer, the third conductive layer, the fourth conductive layer, the positive electrode conductive ring, and the negative electrode conductive ring are obtained by dividing the copper metal layer electroplated on the surface of the adapter board. Among them, the division can be carried out by an etching process.

[0012] Further, a first positive electrode mark and / or a first negative electrode mark are also provided in the first insulating region. The first positive electrode mark is located on one side of the positive electrode conductive ring, and the first negative electrode mark is located on one side of the negative electrode conductive ring.

[0013] In the present invention, the first positive electrode mark and the first negative electrode mark provided on one side of the positive electrode conductive ring and / or the negative electrode conductive ring are used to mark the positions of the positive electrode jack and the negative electrode jack, so as to facilitate distinguishing the positive electrode jack and the negative electrode jack on the adapter board during installation.

[0014] Further, a second positive electrode mark and / or a second negative electrode mark are also provided on the end face of the lithium-ion battery at the end where its positive electrode tab and negative electrode tab are located. The second positive electrode mark is located on one side of the positive electrode tab, and the second negative electrode mark is located on one side of the negative electrode tab.

[0015] In the present invention, the second positive electrode mark and / or the second negative electrode mark provided on the end face of the lithium-ion battery are used to mark the positive electrode tab and the negative electrode tab of the lithium-ion battery, so as to facilitate distinguishing the positive electrode tab and the negative electrode tab on the lithium-ion battery during the installation of the adapter board. In addition, after the adapter board is installed, it is also possible to determine whether the adapter board is correctly installed through the first positive electrode mark, the second positive electrode mark, the first negative electrode mark, and the second negative electrode mark on the adapter board and the lithium-ion battery.

[0016] Further, at least two Mark points are also provided in the first insulating region.

[0017] In the present invention, the Mark points provided in the first insulating region can be used for visual recognition, so as to realize the automatic grasping and installation of the adapter board.

[0018] Further, an insulating protective layer is also covered on the first insulating region. The thickness of the insulating protective layer is greater than that of the first conductive layer, and the insulating protective layer covers the third conductive layer, the positive conductive ring, the negative conductive ring, and the Mark point.

[0019] In the present invention, the insulating protective layer covers the first insulating region on the adapter board, and the thickness of the insulating protective layer is greater than that of the first conductive layer. Therefore, the insulating protective layer will protrude from the top surfaces of the positive conductive region and the negative conductive region, and when the side of the adapter board where the positive conductive region and the negative conductive region are located is attached to the conductive plane, it can prevent the positive conductive region and the negative conductive region from coming into contact with the conductive plane, thereby effectively avoiding the situation of conduction and short circuit between the positive conductive region and the negative conductive region.

[0020] Further, the material used for the insulating protective layer is photocurable glue.

[0021] In the present invention, the insulating protective layer is photocurable glue coated on the first insulating region, and it can be quickly cured after being coated, thereby improving the production efficiency to a certain extent.

[0022] On the other hand, the present invention also provides an adapter board installation process for the above-mentioned lithium-ion battery with an adapter board, including the following steps:

[0023] S1. Determine the lengths a of the positive and negative electrode tabs of the lithium-ion battery according to the thickness of the adapter board, so as to ensure that after the adapter board is covered on the lithium-ion battery, the positive and negative electrode tabs inserted into the positive and negative jacks can be located within the positive and negative jacks.

[0024] S2. Perform a shearing operation on the positive and negative electrode tabs to shear them to a length of a.

[0025] S3. Cover the adapter board on the end of the lithium-ion battery, and insert the positive and negative electrode tabs into the positive and negative jacks respectively.

[0026] S4. Use soldering to weld the tops of the positive and negative electrode tabs to the inner side walls of the positive and negative jacks.

[0027] S5. Use photocurable glue to coat an insulating protective layer in the first insulating region, and make the insulating protective layer cover the third conductive layer, the positive conductive ring, the negative conductive ring, and the welding structure.

[0028] S6. Cure the insulating protective layer.

[0029] Further, before step S1 and after step S6, steps of detecting the voltage and internal resistance of the lithium-ion battery are included to detect defective products. Among them, compared with the invention that only detects the voltage and internal resistance after the adapter board is installed, it can be clearly known whether the defect appears in the lithium-ion battery body or the adapter board.

[0030] The principle and effect of the present invention will be further described below in combination with the above technical solutions and the drawings:

[0031] In the present invention, an adapter board is provided at one end of the lithium-ion battery having tabs, and the positive tab and negative tab of the lithium-ion battery are respectively connected to the positive conductive area and negative conductive area on the adapter board through a conduction structure. Therefore, the positive contact and negative contact of the lithium-ion battery are transferred to the surface of the adapter board, specifically the positive conductive area and negative conductive area. Therefore, when the lithium-ion battery of the present invention is used, only the battery installation structure of the electronic product needs to be adaptively improved, so that the lithium battery of the present invention can be installed and used like a dry battery, thereby achieving the purpose of convenient disassembly of the lithium-ion battery in the electronic product.
