Abstract
Description
Technical Field
[0001] This application belongs to the field of battery technology, specifically relating to a battery module and electronic device. Background Technology
[0002] Batteries, especially lithium-ion batteries, have advantages such as high energy density, high charge-discharge conversion efficiency, and long lifespan, and are widely used in electronic devices such as mobile phones, tablets, laptops, and wearable devices. In different applications, multiple cells are connected in series, parallel, or in a hybrid interconnection to form battery modules to achieve target voltages and capacitances under different conditions. In related technologies, battery modules include cell components and a label layer. The label layer is attached to the surface of the cell components with acrylic adhesive and contains product information for user viewing.
[0003] Battery modules generate heat during charging, discharging, and use. This heat tends to concentrate in certain areas of the module and cannot dissipate evenly and quickly, which can reduce battery module performance and shorten its lifespan. To prevent this heat concentration, related technologies use additional thermally conductive material between the label layer and the acrylic adhesive to accelerate heat dissipation. However, this increases the thickness of the battery module, hindering the reduction of battery component thickness. Utility Model Content
[0004] The purpose of this application is to provide a battery module and electronic device that can solve the problem in the related art where the thickness of the battery module increases due to the additional placement of thermally conductive material between the acrylic adhesive and the label layer.
[0005] In a first aspect, embodiments of this application provide a battery module, including a battery cell assembly, a first thermal conductive patch, and a second thermal conductive patch. The first thermal conductive patch covers a first side of the battery cell assembly, and the second thermal conductive patch covers a second side of the battery cell assembly. The first side and the second side are two opposite sides of the battery cell assembly in its thickness direction, and both the first thermal conductive patch and the second thermal conductive patch include a first thermally conductive adhesive layer. The first thermally conductive adhesive layer is bonded to the battery cell assembly. Product information is provided on the side of the first thermal conductive patch opposite to the battery cell assembly and / or on the side of the second thermal conductive patch opposite to the battery cell assembly.
[0006] Secondly, embodiments of this application also provide an electronic device, including a device body and the aforementioned battery module, wherein the battery module is disposed on the device body.
[0007] In this embodiment, the battery module includes a cell assembly, a first thermally conductive patch, and a second thermally conductive patch. The first and second thermally conductive patches cover the first and second surfaces of the cell assembly, respectively. Both the first and second thermally conductive patches include a first thermally conductive adhesive layer that is bonded to the cell assembly. In this way, the heat of the cell assembly can be conducted through the first thermally conductive adhesive layer, so that the heat generated by the battery module during charging and discharging and during use can be evenly conducted to the entire surface of the battery module. This makes the heat of the battery module uniform, thereby improving the heat dissipation efficiency of the battery module, reducing the overall temperature of the battery module, and reducing the temperature of the electronic devices using the battery module. This can effectively improve the performance of the battery module and extend its service life.
[0008] Furthermore, by connecting the first thermally conductive adhesive layer to the battery cell assembly, the first and second thermally conductive adhesive patches can be connected to the battery cell assembly, so that the first thermally conductive adhesive layer can be used as both a thermally conductive structure and a connection structure. This configuration can save space in the thickness direction of the battery module, thereby improving the space utilization of the battery module and making it easier to reduce the overall thickness of the battery module, which in turn helps to improve the space utilization of electronic devices using battery modules.

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0025] The battery module and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0026] refer to Figures 1-8 The battery module provided in this application embodiment may include a cell assembly 100, a first thermal conductive patch 200, and a second thermal conductive patch 300.
[0027] The first thermally conductive patch 200 can cover the first side of the battery cell assembly 100, and the second thermally conductive patch 300 can cover the second side of the battery cell assembly 100. Here, the first side and the second side can be two opposite sides of the battery cell assembly 100 in its thickness direction, respectively. Both the first thermally conductive patch 200 and the second thermally conductive patch 300 can include a first thermally conductive adhesive layer 220, which can be bonded to the battery cell assembly 100. This configuration allows the first thermally conductive adhesive layer 220 to conduct heat from the battery cell assembly 100, ensuring that the heat generated during charging, discharging, and use is evenly conducted to the entire surface of the battery module. This uniform heat distribution improves the heat dissipation efficiency of the battery module, reduces the overall temperature of the battery module, and lowers the temperature of the electronic devices using the battery module. This effectively improves the performance of the battery module and extends its lifespan. Optionally, both the first thermal conductive patch 200 and the second thermal conductive patch 300 may further include a base layer 210, with a first thermally conductive adhesive layer 220 coated on one side of the base layer 210. The base layer 210 may be made of polyethylene terephthalate (PET) or other materials, and the first thermally conductive adhesive layer 220 may be made of a mixture of acrylic polymer, thermally conductive ceramic powder, and silicone adhesive.
[0028] Here, by connecting the first thermally conductive adhesive layer 220 to the battery cell assembly 100, the first thermally conductive patch 200 and the second thermally conductive patch 300 can be connected to the battery cell assembly 100. This allows the first thermally conductive adhesive layer 220 to function as both a thermally conductive structure and a connecting structure. Compared to battery modules using additional thermally conductive structures, this design saves space in the thickness direction of the battery module, thereby improving the space utilization of the battery module and facilitating overall thinning of the battery module, thus improving the space utilization of electronic devices using battery modules. Furthermore, since the first thermally conductive patch 200 and the second thermally conductive patch 300 cover opposite sides of the battery cell assembly 100 in the thickness direction, they can replace the battery module's casing, effectively reducing the weight of the battery module.
[0029] In addition, product information can be provided on the side of the first thermal conductive patch 200 facing away from the cell assembly 100 and / or the side of the second thermal conductive patch 300 facing away from the cell assembly 100. This arrangement can display information about the battery module for easy observation by the user.
[0030] It should be noted that product information may include battery module specifications, customer information, or other information. There are no specific limitations on product information here; the specifics can be determined based on actual needs.
[0031] In an optional embodiment of this application, both the first thermal conductive patch 200 and the second thermal conductive patch 300 may further include a base layer 210 and a base coating layer 230. The base layer 210, the base coating layer 230, and the first thermal conductive adhesive layer 220 may be stacked sequentially. Furthermore, the base coating layer 230 may be a flame-retardant structure. This configuration allows the base coating layer 230 to effectively retard flames, preventing the battery cell assembly 100 from spontaneously combusting and burning the main body of the electronic device or being burned by other components of the main body. Simultaneously, the stacking of the base layer 210, the base coating layer 230, and the first thermal conductive adhesive layer 220 can form a multi-layer structure for the first thermal conductive patch 200 and the second thermal conductive patch 300, thereby enhancing the overall strength and stability of the first thermal conductive patch 200 and the second thermal conductive patch 300. Moreover, the materials of different layers work together to ensure that the first thermal conductive patch 200 and the second thermal conductive patch 300 can better maintain their shape and performance when subjected to external forces or temperature changes, and are not easily deformed or detached, thus ensuring that they can always effectively perform their thermal conductivity function during long-term use.
[0032] Here, product information may be provided on the side of the base layer 210 of the first thermal conductive patch 200 that faces away from its base coating 230 and / or on the side of the base layer 210 of the second thermal conductive patch 300 that faces away from its base coating 230, so as to ensure that the product information can be exposed.
[0033] In other embodiments, both the first thermal conductive patch 200 and the second thermal conductive patch 300 may not include the base layer 230. Specifically, the first thermal conductive patch 200 and the second thermal conductive patch 300 may only include the base layer 210 and the first thermal conductive adhesive layer 220.
[0034] In optional embodiments, the first thermally conductive patch 200 and / or the second thermally conductive patch 300 may further include a top coating layer 240. The top coating layer 240 may be located on the side of the base layer 210 opposite to the bottom coating layer 230 and may be used to cover product information. Furthermore, the top coating layer 240 may be a transparent structure. This configuration allows the top coating layer 240 to protect the product information from oxidation, damage, or peeling on the base layer 210. Simultaneously, because the top coating layer 240 is transparent, it does not obscure the product information.
[0035] Alternatively, the surface coating 240 may be made of materials such as polypropylene (PP) or nanomaterials.
[0036] In some embodiments, the substrate 210 may be made of polyethylene terephthalate (PET) or other materials, and the color of the substrate 210 may be black, gray, or other colors. Optionally, the thickness of the substrate 210 may be 34-38 micrometers, the thickness of the undercoat 230 may be 15-25 micrometers, the thickness of the first thermally conductive adhesive layer 220 may be 20-30 micrometers, and the thickness of the topcoat 240 may be 2-6 micrometers. Here, the thermal conductivity and thickness of the first thermally conductive adhesive layer 220, as well as other relevant parameters (such as the thickness of the substrate 210, undercoat 230, and topcoat 240), can be adjusted according to different application scenarios and requirements to achieve optimal thermal conductivity.
[0037] In an optional embodiment of this application, the battery cell assembly 100 may include a frame 130 and at least one battery cell 110. The frame 130 may be provided with at least one battery cell mounting slot 131, and one battery cell 110 may be installed in one battery cell mounting slot 131. The first thermal conductive patch 200 and the second thermal conductive patch 300 may both be connected to the frame 130 and the battery cell 110. With this configuration, the first thermal conductive patch 200 and the second thermal conductive patch 300 can conduct heat from the battery cell 110 to the frame 130, and then dissipate the heat through the frame 130, thereby further improving the heat dissipation efficiency of the battery module. Optionally, the battery cell assembly 100 may include at least two battery cells 110, and at least one partition 133 may be provided within the frame 130 to divide the frame 130 into at least two battery cell mounting slots 131. Optionally, the number of battery cells 110 can be the same as the number of battery cell mounting slots 131, in which case each battery cell 110 is installed in each battery cell mounting slot 131 in a one-to-one correspondence; or, the number of battery cells 110 can be greater than the number of battery cell mounting slots 131, in which case at least two battery cells 110 are installed in at least one battery cell mounting slot 131.
[0038] In other embodiments, the first thermal pad 200 and the second thermal pad 300 may also be connected only to the battery cell 110.
[0039] In an optional embodiment, the battery module may further include a third thermal conductive patch (not shown in the figure), which may be connected to the first thermal conductive patch 200, and a portion of the third thermal conductive patch may be bent to the second side and connected to the second thermal conductive patch 300; and / or, the battery module may further include a fourth thermal conductive patch 400, which may be connected to the second thermal conductive patch 300, and a portion of the fourth thermal conductive patch 400 may be bent to the first side and connected to the first thermal conductive patch 200. This configuration allows the first thermally conductive patch 200 and / or the second thermally conductive patch 300 to indirectly form multi-point connections with the battery cell assembly 100 through the third and / or fourth thermally conductive patch 400. This more effectively disperses the stress on the first and second thermally conductive patches 200 and 300, reducing the risk of them detaching or being damaged due to localized stress concentration. This improves the connection stability between the first and second thermally conductive patches 200 and 300 and the battery cell assembly 100. Furthermore, the addition of the third and / or fourth thermally conductive patch 400 increases the heat conduction area, allowing more heat to be conducted simultaneously, thus improving the overall heat dissipation efficiency of the battery module. Moreover, by bending the third and / or fourth thermally conductive patch 400, heat can be conducted more quickly from high-temperature areas to low-temperature areas, such as from the area where the battery cell 110 is located to the side of the frame 130, thereby enhancing the heat conduction effect.
[0040] In some embodiments, the third thermal conductive patch and the first thermal conductive patch 200 can be an integral structure, and the fourth thermal conductive patch 400 and the second thermal conductive patch 300 can be an integral structure. This can improve the connection stability between the third thermal conductive patch and the first thermal conductive patch 200, and the connection stability between the fourth thermal conductive patch 400 and the second thermal conductive patch 300.
[0041] In this embodiment, the battery module may include only the third thermal conductive patch, only the fourth thermal conductive patch 400, or both the third and fourth thermal conductive patches 400.
[0042] Optionally, the third and / or fourth thermal conductive pads 400 include a second thermally conductive adhesive layer, which is connected to the frame 130. This configuration allows the third and / or fourth thermal conductive pads 400 to be fixed to the frame 130 via the second thermally conductive adhesive layer, while also conducting heat from the first and second thermal conductive pads 200 and 300 to the sides of the frame 130, thereby further improving heat dissipation.
[0043] Of course, the third and / or fourth thermal pads 400 may also exclude the second thermal adhesive layer.
[0044] Further optionally, at least four third and / or fourth thermal conductive pads 400 are provided. This arrangement helps to improve the thermal conductivity, thereby improving the heat dissipation of the battery module. Optionally, each third and / or each fourth thermal conductive pad 400 can be distributed circumferentially along the frame 130. This arrangement helps to improve the uniformity of heat dissipation of the battery module.
[0045] The frame 130 has a rectangular structure, and each side of the frame 130 is connected to at least one third thermal conductive pad and / or at least one fourth thermal conductive pad 400. This configuration, on the one hand, further enhances the connection strength between the first thermal conductive pad 200 and the second thermal conductive pad 300 and the battery cell assembly 100; on the other hand, it allows for the uniform conduction of heat from the first thermal conductive pad 200 and the second thermal conductive pad 300 to the four sides of the frame 130, thereby promoting more uniform heat distribution within the battery module. Figure 5 As shown, the frame 130 is connected to a fourth thermal conductive patch 400 on each of its two sides in the length direction, and the frame 130 is connected to two fourth thermal conductive patches 400 on each of its two sides in the width direction.
[0046] Optionally, the third and / or fourth thermal conductive pads 400 may also include a base layer 210 and a primer layer 230 stacked sequentially, with the second thermally conductive adhesive layer located on the side of the primer layer 230 facing away from the base layer 210. This configuration allows the third and / or fourth thermal conductive pads 400 to possess flame-retardant properties and improves their overall strength and stability, making them less prone to breakage.
[0047] In an optional embodiment, both the first thermally conductive adhesive layer 220 and the second thermally conductive adhesive layer can be made of a mixture of acrylic polymer, thermally conductive ceramic powder and silicone adhesive, so that both the first thermally conductive adhesive layer 220 and the second thermally conductive adhesive layer have high thermal conductivity and insulation properties, while also having flexibility, compressibility, conformability and strong adhesion, which can adapt to a wide temperature range, conduct heat away quickly, and fill uneven surfaces to make the surface of the battery module smoother.
[0048] It should be noted that when the first thermally conductive sticker 200, the second thermally conductive sticker 300, the third thermally conductive sticker, and / or the fourth thermally conductive sticker 400 are not attached to the battery cell assembly 100, release paper 500 can be provided on the side of the first thermally conductive adhesive layer 220 facing away from the base layer 210, and release paper 500 can be provided on the side of the second thermally conductive adhesive layer facing away from the base layer 210, to prevent the first and second thermally conductive adhesive layers 220 and 220 from adhering to other substances or to prevent damage to the first and second thermally conductive adhesive layers 220 and 220. Here, the release paper 500 can be made of glassine mesh paper.
[0049] In an optional embodiment, the cell assembly 100 may further include a protection board assembly 120. The cell 110 can be electrically connected to the protection board assembly 120. When the cell assembly 100 includes at least two cells 110, each cell 110 is electrically connected to the protection board assembly 120. This arrangement has several advantages. First, by using one protection board assembly 120 to connect at least two cells 110, the number of protection board assemblies 120 can be reduced, thereby simplifying the structure of the entire cell assembly 100. This also has a positive effect on improving production efficiency, reducing costs, and reducing potential failure points. Second, since the cells 110 are electrically connected to the protection board assembly 120, space can be utilized more effectively, avoiding excessive space occupation by multiple protection board assemblies 120. At the same time, connecting the cells 110 to the same protection board assembly 120 helps ensure the electrical performance consistency between the cells 110. The protection board assembly 120 can balance and adjust the voltage, current, and other parameters of the cells 110, reducing differences between the cells 110, which is beneficial to improving the overall performance of the battery module and extending the service life of the battery module.
[0050] Of course, the cell assembly 100 may also include at least two protection board assemblies 120, each of which is electrically connected to each cell 110.
[0051] Additionally, a protection board mounting slot 132 can be provided within the frame 130, and the cell mounting slot 131 can communicate with the protection board mounting slot 132. The protection board assembly 120 can be located within the protection board mounting slot 132. This arrangement simplifies the structure of the frame 130 compared to a frame 130 having at least two protection board mounting slots 132.
[0052] Of course, if the frame 130 is provided with at least two cell mounting slots 131, the frame 130 may also be provided with at least two protection board mounting slots 132, each protection board mounting slot 132 being connected to each cell mounting slot 131, and each protection board assembly 120 being located in each protection board mounting slot 132.
[0053] In an optional embodiment, the battery cell assembly 100 may further include a support plate 150, which may be located within the protection board mounting groove 132. The support plate 150 may be positioned close to and connected to the first thermal conductive patch 200. The protection board assembly 120 is connected to an external connector 140 for electrical connection with the main body of an electronic device, and the external connector 140 may be mounted on the support plate 150. This configuration allows the support plate 150 to support and fix the external connector 140, ensuring that the external connector 140 is not prone to shaking or misalignment during use. This improves the connection stability between the external connector 140 and the protection board assembly 120. Furthermore, since the support plate 150 is connected to the first thermal conductive patch 200, it can also conduct heat from the protection board assembly 120 and the external connector 140 to the first thermal conductive patch 200, thereby enhancing the heat dissipation effect of the protection board assembly 120 and the external connector 140.
[0054] In other embodiments, the cell assembly 100 may not include the support plate 150, and the external connector 140 may be connected only to the protection plate assembly 120.
[0055] Optionally, in order to facilitate the connection between the external connector 140 and the external wire, a clearance opening (not shown in the figure) may be provided on the frame 130. The clearance opening may communicate with the protection plate mounting groove 132 and may correspond to the external connector 140. Specifically, the clearance opening may be provided on the side wall of the frame 130.
[0056] In an optional embodiment, a limiting plate 134 may also be provided within the frame 130. The limiting plate 134 may be located close to and connected to the first thermal conductive patch 200, and may also be connected to the partition plate 133. In the direction from the first surface to the second surface of the cell assembly 100, the limiting plate 134 and the cell 110 are mutually limiting and engaged. This arrangement allows the limiting plate 134 to limit the cell 110, preventing displacement of the cell 110 in the thickness direction. Alternatively, the limiting plate 134 may also be located close to and connected to the second thermal conductive patch 300, and in the direction from the second surface to the first surface of the cell assembly 100, the limiting plate 134 and the cell 110 are mutually limiting and engaged.
[0057] Optionally, the limiting plate 134 can be positioned on the frame 130 away from the support plate 150. It is sufficient for the limiting plate 134 to perform a limiting function. It is not necessary to make the size of the limiting plate 134 large. This reduces the size of the limiting plate 134, which helps to reduce the weight of the battery module. At the same time, since the limiting plate 134 is smaller, the contact area between the first thermal conductive patch 200 and the cell 110 can be increased, which helps to improve the heat conduction effect on the cell 110.
[0058] Based on the battery module provided in the embodiments of this application, the embodiments of this application also provide an electronic device, which may include a device body and the battery module described in any of the above embodiments, and the battery module may be disposed on the device body.
[0059] The beneficial effects achieved by the electronic device provided in this application embodiment are consistent with the beneficial effects achieved by the battery module provided in this application embodiment, and will not be repeated here.
[0060] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
