During installation, the viscosity of the electrolyte can stick the battery to the electronic device. During disassembly, an electric field can be formed between the metals on both sides of the electrolyte by energizing the metals on both sides of the electrolyte to achieve electrolysis of the electrolyte.

[0072] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0073] In order to ensure the sealing performance and battery life of electronic devices such as mobile phones, tablets, and laptops, the batteries used in electronic devices are usually assembled in the electronic devices in a non-detachable manner. The above-mentioned assembly method of the battery enables the battery to have a higher unit volume capacity, thereby extending the battery life of the electronic device, and also facilitates the sealed assembly of the electronic device, thereby improving the sealing performance of the electronic device.

[0074] Although the above-mentioned assembly method of batteries in electronic devices can improve the sealing performance and battery life of electronic devices, it is not conducive to the disassembly and replacement of batteries. It is difficult for ordinary consumers to disassemble and replace batteries by conventional means.

[0075] Based on the above considerations, electrolytic glue can be used to complete the installation of the battery, which can reduce the difficulty of battery installation and removal to a certain extent. The electrolytic glue is a double-sided tape. Generally, the electrolytic glue has sufficient viscosity. In an electric field environment, the electrolytic glue can be electrolyzed to lose viscosity or weaken viscosity.

[0076] Therefore, electrolytic gel can be used as a component of the installation structure of the battery in the electronic device. The battery can be installed in the electronic device by utilizing the viscosity of the electrolytic gel and the property that it can be electrolyzed in an electric field environment. During installation, the viscosity of the electrolytic gel can stick the battery to the electronic device. During disassembly, an electric field can be formed between the metals on both sides of the electrolytic gel by energizing the metals on both sides to achieve electrolysis of the electrolytic gel.

[0077] The battery can usually be installed in a designated position of an electronic device, for example, the battery can be installed in a metal battery compartment of the electronic device, the metal battery compartment can be an independent component of the electronic device, and the metal battery compartment can also be formed by the frame, back shell and other structures of the electronic device. The metal battery compartment usually has a recessed area, which is usually designed to be a cuboid or other shapes, and the battery can be installed in the recessed area.

[0078] After the battery is installed in the recessed area, the electrolytic gel can be outwrapped on the surface of the battery facing the metal battery compartment. For ease of understanding, the side where the metal battery compartment is located can be understood as the outside of the electrolytic gel. In other words, the metal battery compartment is located on the outside of the electrolytic gel. To facilitate the formation of an electric field environment, a conductive layer is also required on the side of the electrolytic gel facing away from the metal battery compartment. For ease of understanding, the side facing away from the metal battery compartment can be understood as the inside of the electrolytic gel. In other words, the conductive layer is located on the inside of the electrolytic gel. The conductive layer can be made of metal materials such as copper and aluminum. The conductive layer is another component of the above-mentioned installation structure. The above-mentioned electric field environment can be formed by energizing the conductive layer and the metal battery compartment. For example, the positive pole of the external power supply is connected to the conductive layer, and the negative pole of the external power supply is connected to the metal battery compartment.

[0079] In order to prevent contact short circuit between the conductive layer and the metal battery compartment, an insulating structure can be provided between the conductive layer and the metal battery compartment. The insulating structure can be another component of the above-mentioned installation structure. The insulating structure can include the aforementioned electrolytic gel, and can also include other components with insulating properties. In the related art, the design of the electrolytic gel, the conductive layer and the insulating structure is not reasonable enough. This unreasonableness is mainly reflected in the difficulty in balancing the insulating performance of the insulating structure, the assembly and disassembly performance of the electrolytic gel and the capacity of the battery. Although the insulating structure is too large to achieve insulation between the conductive layer and the metal battery compartment, it is easy to affect the assembly and disassembly performance of the electrolytic gel and the capacity of the battery. Although the insulating structure is too small to ensure the assembly and disassembly performance of the electrolytic gel and the battery capacity, it is difficult to achieve insulation between the conductive layer and the metal battery compartment. As a conventional design idea, the battery is usually assembled in a way that does not affect the assembly and disassembly performance of the electrolytic gel and the capacity of the battery as much as possible, which will cause the conductive layer and the metal battery compartment to be easily contacted and short-circuited, the electrolytic gel cannot be electrolyzed, and the battery is difficult to remove from the electronic device.

[0080] In response to the above problems and current situations, an embodiment of the present application provides a battery that can be used in various electronic devices such as mobile phones, tablet computers, and laptop computers. The battery is configured with an assembly and disassembly structure formed by components such as electrolyte, making the battery easy to install and disassemble.

[0081] To achieve the above-mentioned purpose, the assembly and disassembly structure in the embodiment of the present application adopts a design concept that can isolate local parts, so that when the above-mentioned contact short circuit occurs, a certain part or some parts of the assembly and disassembly structure corresponding to the location where the contact short circuit occurs can be isolated, and the electrolyte gel in the remaining parts of the assembly and disassembly structure can still be electrolyzed and lose its viscosity, thereby achieving the purpose of the battery still being able to be disassembled when a contact short circuit occurs.

[0082] The assembly and disassembly structure in the embodiment of the present application has at least two states, one of which is an integrated state in which various parts can be connected into one. When no contact short circuit occurs, the assembly and disassembly structure in the integrated state can electrolyze the electrolyte gel inside it by a one-time power-on. The other state is a split state in which one or some parts can be isolated. When a contact short circuit occurs, the assembly and disassembly structure can be switched from the integrated state to the split state, so that the electrolyte gel in the unisolated part of the assembly and disassembly structure can be electrolyzed.

[0083] To this end, the assembly and disassembly structure in the embodiment of the present application needs to at least be provided with a connecting portion that connects multiple parts into one body, and the assembly and disassembly structure can be switched from an integrated state to a separated state by tearing or cutting the connecting portion with external force.

[0084] The assembly and disassembly structure in the embodiments of the present application can at least achieve a reasonable balance between the assembly and disassembly performance of the battery and the capacity of the battery. It can be understood that in some embodiments of the assembly and disassembly structure, an insulating structure can also be provided, such as the insulating layer in the following embodiments, so that the battery can achieve a reasonable balance between the insulating performance of the insulating structure, the assembly and disassembly performance of the electrolyte and the capacity of the battery.

[0085] Figure 1 A partial cross-sectional view of an electronic device provided according to an embodiment of the present application is shown.

[0086] In the examples of this application, please refer to Figure 1 The electronic device includes a metal battery compartment 100 and a battery 200 . The metal battery compartment 100 is formed with a recessed area 101 . The recessed area 101 is adapted to the shape of the battery 200 . The battery 200 can be installed in the recessed area 101 .

[0087] The electronic device may be a mobile phone, a tablet computer or a laptop computer, etc. The electronic device may include a shell, and the shell may include a frame and a back shell, etc. The metal battery compartment 100 may be a separate component arranged in the shell, and the metal battery compartment 100 may also be formed by the shell and / or the back shell. In other words, in order to form the recessed area 101, a separate component that can form the recessed area 101 may be provided for the electronic device, or the shell of the electronic device may be designed to have a recessed area 101.

[0088] The battery 200 can be designed into various shapes, which can be a square battery 200 or a round battery 200. For ease of understanding and description, the embodiment of the present application is mainly described by taking the square battery 200 as an example. Correspondingly, the recessed area 101 is also described by taking the rectangular structure as an example.

[0089] The metal battery compartment 100 is formed with a bottom wall 102 and four side walls 103 perpendicular to the bottom wall 102 at the recessed area 101 (see Figure 3 ), a bottom wall 102 and four side walls 103 form a recessed area 101. The battery 200 can be confined in the recessed area 101.

[0090] The battery 200 is provided with a mounting and disassembly structure 210 , and a connection portion 2112 in the mounting and disassembly structure 210 can extend from the recessed area 101 to be exposed outside the metal battery compartment 100 .

[0091] When assembling the battery 200 of the electronic device, the battery 200 can be placed in the recessed area 101, and the electrolytic gel in the assembly and disassembly structure 210 of the battery 200 can be bonded to the bottom wall 102 and / or the side wall 103 of the metal battery compartment 100; when disassembling the battery 200, when no contact short circuit occurs, the electrolytic gel can be electrolyzed by energizing the metal battery compartment 100 and the assembly and disassembly structure 210, and then the battery 200 can be picked up to complete the disassembly of the battery 200. After a contact short circuit occurs, the part where the contact short circuit occurs can be isolated by tearing or cutting, and the electrolytic gel in the unisolated part of the assembly and disassembly structure 210 can continue to be electrolyzed, and then the battery 200 can be picked up to complete the disassembly of the battery 200.

[0092] The electronic device in the embodiment of the present application can realize the installation and removal of the battery 200, and the operation is simple, stable and reliable, and the purpose of the battery 200 still being able to be removed when a contact short circuit occurs can be achieved.

[0093] Figure 2 A schematic diagram of the structure of removing a battery when no contact short circuit occurs in an electronic device provided by an embodiment of the present application is shown; Figure 3 Another structural schematic diagram of an electronic device provided by an embodiment of the present application for removing a battery when no contact short circuit occurs is shown; Figure 4 A cross-sectional view of an electronic device provided by an embodiment of the present application when a battery is disassembled without a contact short circuit is shown; Figure 5 Another cross-sectional view of an electronic device provided by an embodiment of the present application when a battery is disassembled without a contact short circuit is shown.

[0094] First, please refer to Figure 2 and Figure 4 The battery 200 is installed in the recessed area 101, and the connecting portion 2112 of the battery 200 extends out of the recessed area 101. Before disassembling the battery 200, first connect the external power supply 10 to the connecting portion 2112 and the metal battery compartment 100. For example, the positive electrode of the external power supply 10 is connected to the connecting portion 2112, and the negative electrode of the external power supply 10 is connected to the metal battery compartment 100. After power is turned on, the electrolytic gel in the assembly and disassembly structure 210 will be electrolyzed and lose its viscosity; then, please refer to Figure 3 and Figure 5 After the electrolyte loses its viscosity, the battery 200 can be removed from the recessed area 101 by applying force to the battery 200 .

[0095] Figure 6 A schematic diagram of a structure of removing a battery when a contact short circuit occurs in an electronic device provided by an embodiment of the present application is shown; Figure 7 Another structural schematic diagram of removing a battery when a contact short circuit occurs in an electronic device provided by an embodiment of the present application is shown.

[0096] First, please refer to Figure 4 Before disassembling the battery 200, first connect the external power source 10 to the connecting portion 2112 and the metal battery compartment 100. If the battery 200 cannot be disassembled by applying force, it means that the electrolytic gel has not been electrolyzed and the viscosity of the electrolytic gel still exists. Next, please refer to Figure 6 , the corresponding positions of the connecting part 2112 are cut off by tearing or cutting so that multiple parts are isolated from each other, each part can correspond to a sub-connecting part 2112a, and then the external power supply 10 is connected to each isolated sub-connecting part 2112a and the metal battery compartment 100 in turn to electrolyze the electrolytic gel in different areas. In the above process, only the electrolytic gel at the contact short circuit location cannot be electrolyzed, and the rest of the electrolytic gel can be electrolyzed. Finally, the battery 200 can also be removed from the recessed area 101 by applying force to the battery 200.

[0097] exist Figures 2 to 7 In the example shown, it can be understood that, in order to facilitate the power supply between the connection part 2112, the sub-connection part 2112a and the metal battery compartment 100, the connection part 2112 and the sub-connection part 2112a can be a flip-up structure formed on the edge of the battery 200. It should be recognized that when the battery 200 is normally in the electronic device, in order to reduce the space, the connection part 2112 and the sub-connection part 2112a can be directly attached to the surface of the corresponding structure of the battery 200. For example, it can be recognized in the following embodiments that the connection part 2112 and the sub-connection part 2112a can be attached to the surface of the battery cell 220. When the battery 200 needs to be disassembled, the connection part 2112 and the sub-connection part 2112a can be flipped up.

[0098] Figure 8 A schematic diagram of the structure of a battery provided according to an embodiment of the present application is shown; Fig. 9 A schematic diagram of an explosion of a battery provided according to an embodiment of the present application is shown.

[0099] In the examples of this application, please refer to Figure 8 and Fig. 9 The battery 200 includes a battery cell 220 and a mounting and disassembly structure 210 , and the mounting and disassembly structure 210 is connected to at least one side of the battery cell 220 .

[0100] In combination with the foregoing, the embodiments of the present application are mainly described by taking the square battery 200 as an example. Correspondingly, the present application is also mainly described by taking the square structured battery cell 220 as an example.

[0101] The battery cell 220 may be a laminated structure or a rolled core structure. When the former is adopted, the battery cell 220 may include a positive electrode sheet, a separator and a negative electrode sheet, and the positive electrode sheet, the separator and the negative electrode sheet are sequentially overlapped to form the battery cell 220. When the latter is adopted, the battery cell 220 may also include a positive electrode sheet, a negative electrode sheet and a separator, and the three may be wound clockwise or counterclockwise to form a structure.

[0102] For ease of understanding, the battery cell 220 includes a front side 221 and a back side 222 that are arranged oppositely, wherein the back side 222 is the side of the battery cell 220 facing the recessed area 101, and the front side 221 is the side of the battery cell 220 that is away from the recessed area 101. A pair of oppositely arranged long side surfaces 223 and a pair of oppositely arranged short side surfaces 224 are connected between the front side 221 and the back side 222, wherein the long side surfaces 223 correspond to the length direction of the battery cell 220, and the short side surfaces 224 correspond to the width direction of the battery cell 220.

[0103] by Figure 8 Taking the orientation shown as an example, the front side 221 and the back side 222 are located in the XY plane, and the front side 221 is on the upper side in the Z direction, the back side 222 is on the lower side in the Z direction, the long side 223 is located in the XZ plane, and the short side 224 is located in the YZ plane. The pair of long side surfaces 223 includes a left side surface and a right side surface, wherein the left side surface is located on the left side in the Y direction, and the right side surface is located on the right side in the Y direction; the pair of short side surfaces 224 includes a front side surface and a rear side surface, wherein the front side surface is located on the front side in the Z direction, and the rear side surface is located on the rear side in the Z direction.

[0104] In the above description, it can be appreciated that the Z direction defines the upper side and the lower side, the X direction defines the front side and the rear side, and the Y direction defines the left side and the right side.

[0105] In the above-mentioned square-structured battery cell 220, the detachable structure 210 is connected to at least one side of the battery cell 220, which means that the detachable structure 210 is at least connected to the back side 222 of the battery cell 220, so that the back side 222 of the battery cell 220 can be bonded to the recessed area 101. In some embodiments, the detachable structure 210 can also be connected to the long side 223, the short side 224 or the front side 221 of the battery cell 220.

[0106] In some embodiments, please refer to Figure 8 The assembly and disassembly structure 210 is simultaneously connected to the back side 222 , the long side 223 or the short side 224 of the battery cell 220 and part of the front side 221 of the battery cell 220 . The assembly and disassembly structure 210 located at the front side 221 of the battery cell 220 may include the aforementioned connection portion 2112 .

[0107] In the above embodiment, the assembly and disassembly structure 210 connected to the back side 222 can ensure that there is a sufficient contact area between the battery 200 and the metal battery compartment 100, and can ensure reliable adhesion between the two, thereby ensuring the assembly and disassembly performance of the assembly and disassembly structure 210. The assembly and disassembly structure 210 connected to the long side 223 or the short side 224 can make the assembly and disassembly structure 210 extend from the recessed area 101, so that the connecting part 2112 is located outside the recessed area 101, which is convenient for the subsequent disassembly operation of the battery 200.

[0108] In some embodiments, in order to increase the capacity of the battery 200, the assembly and disassembly structure 210 can be designed to be connected to one of the long side 223 or the short side 224. For ease of understanding and description, the following embodiments are mainly described using the assembly and disassembly structure 210 connected to the long side 223 of the battery cell 220 as an example.

[0109] exist Figure 8 In the example shown, the assembly and disassembly structure 210 is connected to the back side 222, the right side and part of the front side 221 of the battery cell 220. To match the shape of the battery cell 220, the assembly and disassembly structure 210 is curved as a whole. The part of the assembly and disassembly structure 210 connected to the front side 221 can be attached to the front side 221, and the connecting part 2112 is located in this part. When the battery 200 is disassembled, the connecting part 2112 can be flipped up from the front side 221.

[0110] It is understandable that by properly configuring the connection design between the assembly and disassembly structure 210 and the battery cell 220 , the capacity of the battery 200 can be improved while ensuring the assembly and disassembly performance of the assembly and disassembly structure 210 .

[0111] The battery 200 in the embodiment of the present application can be quickly installed and disassembled based on the design of the assembly and disassembly structure 210. When installing the battery 200, the battery 200 can be placed in the recessed area 101, and the electrolytic gel in the assembly and disassembly structure 210 of the battery 200 can be bonded to the bottom wall 102 of the metal battery compartment 100; when disassembling the battery 200, when no contact short circuit occurs, the electrolytic gel can be electrolyzed by energizing the metal battery compartment 100 and the assembly and disassembly structure 210, and then the battery 200 can be picked up to complete the disassembly of the battery 200. After a contact short circuit occurs, the part where the contact short circuit occurs can be isolated by tearing or cutting, and the electrolytic gel in the remaining part of the assembly and disassembly structure 210 can continue to be electrolyzed, and then the battery 200 can be picked up to complete the disassembly of the battery 200.

[0112] In combination with the foregoing, when disassembling the battery 200, the force can be applied to the battery cell 220 or to the flipped-up connecting portion 2112. To prevent the connecting portion 2112 from being subjected to insufficient force, the battery 200 can also be provided with an auxiliary structure, which can provide more points of force for the external force.

[0113] Fig.10 A schematic diagram of assembling a handle structure provided according to an embodiment of the present application is shown;

[0114] In some embodiments, please refer to Fig.10 The battery 200 may further include a handle structure 300, which is connected to the battery cell 220. The handle structure 300 has a fitted state where it is attached to the battery cell 220 and a flipped state where it can be flipped up under an external force.

[0115] The handle structure 300 can be arranged on the same side of the connecting portion 2112 or on the opposite side of the connecting portion 2112. After the electrolyte gel is electrolyzed, the handle structure 300 can be flipped up, and then the battery 200 can be picked up by applying force to the handle structure 300 and / or the connecting portion 2112.

[0116] Fig.11 A structural principle diagram of an assembly and disassembly structure in an integrated state provided in an embodiment of the present application is shown; Fig.12 A structural principle diagram of an assembly and disassembly structure in a split state provided according to an embodiment of the present application is shown.

[0117] In the examples of this application, please refer to Figure 1 and Figure 11 to Figure 12 The assembly and disassembly structure 210 includes a conductive layer 211 and an electrolytic glue layer 212. The conductive layer 211 can be made of a conductive metal material, and the electrolytic glue layer 212 can be made of electrolytic glue.

[0118] The conductive layer 211 includes a plurality of mutually isolated contact portions 2111 and a connecting portion 2112 connected to the plurality of contact portions 2111 . The electrolytic gel layer 212 is connected to one side of the conductive layer 211 .

[0119] The conductive layer 211 and the aforementioned metal battery compartment 100 form metal on both sides of the electrolytic layer 212. After the battery 200 is installed in the metal battery compartment 100, the electrolytic layer 212 is located between the conductive layer 211 and the metal battery compartment 100. When the battery 200 is disassembled, the external power supply 10 can be connected to the conductive layer 211 and the metal battery compartment 100.

[0120] The contact portions 2111 in the conductive layer 211 form various parts of the aforementioned assembly and disassembly structure 210. The connection portion 2112 can form an integrated assembly and disassembly structure 210 after being connected to multiple contact portions 2111. When the battery 200 is disassembled, the external power source 10 can be connected to the connection portion 2112 and the metal battery compartment 100. After being split and connected by tearing or cutting, the connection portion 2112 is split into multiple sub-connection portions 2112a, and the multiple contact portions 2111 are isolated. The sub-connection portions 2112a are connected to the contact portions 2111. When the battery 200 is disassembled, the external power source 10 can be connected to the sub-connection portion 2112a and the metal battery compartment 100.

[0121] In order to match the back side 222 and the long side 223 of the battery cell 220 , the conductive layer 211 is designed to have a planar structure with a certain thickness, and the electrolytic gel layer 212 is connected to one surface of the conductive layer 211 .

[0122] The assembly and disassembly structure 210 in the embodiment of the present application can be installed in and removed from a designated position such as the metal battery compartment 100 based on the viscosity of the electrolytic gel layer 212 and the property that it can be electrolyzed in an electric field environment. When disassembling the assembly and disassembly structure 210, power can be passed between the metal battery compartment 100 and the conductive layer 211 so that the electrolytic gel layer 212 is electrolyzed and loses or weakens its viscosity, thereby completing the disassembly operation of the assembly and disassembly structure 210. If the assembly and disassembly structure 210 is still difficult to disassemble after power is passed, the connecting portion 2112 can be divided by tearing or cutting so that multiple contact portions 2111 are isolated. The electrolytic gel layer 212 corresponding to the contact short circuit in the isolated contact portion 2111 cannot be electrolyzed, and the remaining electrolytic gel layers 212 can still be electrolyzed, and the disassembly operation of the assembly and disassembly structure 210 can also be achieved.

[0123] The assembly and disassembly structure 210 in the embodiment of the present application can realize the assembly and disassembly of the battery 200 and other components, and the operation is simple, stable and reliable, and the battery 200 can still be disassembled when a contact short circuit occurs.

[0124] The embodiment of the present application mainly uses the installation and removal of the assembly and disassembly structure 210 applied to the battery 200 as an example for explanation. To correspond to the shape of the battery 200, the assembly and disassembly structure 210 can be designed into the curved shape described above. It can be understood that the assembly and disassembly structure 210 in the embodiment of the present application can also be applied to other fields. For example, the assembly and disassembly structure 210 can be applied to the installation of the back shell of an electronic device by connecting the assembly and disassembly structure 210 to the back shell and then assembling the back shell to the housing of the electronic device. In other applications of the assembly and disassembly structure 210, the assembly and disassembly structure 210 can be designed into more structures, which can be curved, flat, etc.

[0125] It is understandable that the electrolytic layer 212 in the embodiment of the present application can form connections with the conductive layer 211 of different areas, and the electrolytic layer 212 can cover the entire conductive layer 211 or only cover the contact portion 2111 in the conductive layer 211 .

[0126] For example, in some embodiments, the electrolytic layer 212 may cover at least a portion of the contact portion 2111 and the connecting portion 2112 . In this embodiment, the electrolytic layer 212 may cover the entire contact portion 2111 and a portion of the connecting portion 2112 .

[0127] For example, in some embodiments, the electrolyte layer 212 covers at least a portion of the contact portion 2111 , and a portion of the space corresponding to the connection portion 2112 in the conductive layer 211 is reserved, so that a structure with better performance can be provided for the assembly and disassembly structure 210 .

[0128] In some embodiments, please refer to Fig.11 and Fig.12 The assembly and disassembly structure 210 may further include an insulating layer 213 , which is connected to one side of the conductive layer 211 and connected to the electrolytic gel layer 212 .

[0129] The provision of the insulating layer 213 can better form insulation between the conductive layer 211 and the metal battery compartment 100 and the like, thereby preventing the conductive layer 211 and the metal battery compartment 100 and the like from contacting and short-circuiting.

[0130] In some embodiments, the insulating layer 213 at least partially overlaps with the electrolytic layer 212, and the size of the overlapping area can be greater than 0 mm, which can prevent a gap 2115 from being left between the insulating layer 213 and the electrolytic layer 212, thereby preventing contact between the conductive layer 211 and the metal battery compartment 100, etc.

[0131] In some embodiments, the electrolytic layer 212 is an integral structure, and the electrolytic layer 212 of the integral structure can cover the contact portion 2111 in the conductive layer 211 .

[0132] Providing the electrolytic gel layer 212 as an integral structure can simplify the formation of the electrolytic gel layer 212 .

[0133] In some embodiments, the electrolytic glue layer 212 may include a plurality of sub-glue layers 2121 , the number of the sub-glue layers 2121 is the same as the number of the contact portions 2111 , and one sub-glue layer 2121 covers one contact portion 2111 .

[0134] Similarly, the insulating layer 213 may also be designed similarly to the electrolytic gel layer 212 , which will not be described in detail.

[0135] In order to adapt to the application of the detachable structure 210 in the battery 200 and realize the connection between the detachable structure 210 and the battery cell 220, the detachable structure 210 can be designed to be curved, or the detachable structure 210 can be designed to be flat and can be bent along the edge of the battery cell 220. It can be understood that the above-mentioned curved shape and flat shape are presentations of different structures of the detachable structure 210, and the two can be transformed into each other. In order to facilitate a comprehensive understanding of the structure and performance of the detachable structure 210, the following embodiments will mainly take the flat detachable structure 210 as an example for explanation. When realizing the connection between the battery cell 220 and the detachable structure 210, the detachable structure 210 can be bent into a curved shape.

[0136] Fig.13 A front view of an assembly and disassembly structure provided according to an embodiment of the present application is shown; Fig.14 A top view of an assembly and disassembly structure provided according to an embodiment of the present application is shown; Fig.15 A bottom view of an assembly and disassembly structure provided according to an embodiment of the present application is shown.

[0137] In the first embodiment, please refer to Figures 13 to 15 The assembly and disassembly structure 210 includes a conductive layer 211, an electrolytic layer 212 and an insulating layer 213. Fig.13 Taking the illustrated aspect as an example, the conductive layer 211 is formed with an upper surface 2113 and a lower surface 2114 , and the electrolytic gel layer 212 and the insulating layer 213 are connected to the lower surface 2114 of the conductive layer 211 .

[0138] The conductive layer 211 includes a plurality of contact portions 2111 and a connection portion 2112 connected to the plurality of contact portions 2111 . The plurality of contact portions 2111 are parallel to each other and arranged at intervals. The contact portions 2111 may be formed by strips of aluminum foil or the like. The connection portion 2112 is connected to the same end of the plurality of contact portions 2111 .

[0139] exist Figures 13 to 15 In the example shown, to adapt to the square structure of the battery cell 220 , the conductive layer 211 may be a rectangular structure, and a gap 2115 is formed between two adjacent contact portions 2111 . The gap 2115 may be greater than 0.2 mm to prevent a short circuit between the two contact portions 2111 .

[0140] It is understandable that, in order to prevent the conductive layer 211 from directly contacting the metal battery compartment 100, the overall size of the conductive layer 211 should be smaller than the size of the recessed area 101, so that the edges of the conductive layer 211 can be retracted into the four side walls 103 of the recessed area 101. In addition, the end of the electrolytic gel layer 212 can extend out of the conductive layer 211, and the electrolytic gel layer 212 can abut against the side wall 103.

[0141] It is understandable that the electrolyte gel layer 212 extending out of the conductive layer 211 cannot be electrolyzed. Therefore, in order to prevent the electrolyte gel layer 212 from still being sticky and making it difficult to disassemble the battery 200 due to the inability to electrolyze this part of the electrolyte gel layer 212, the size of the electrolyte gel layer 212 extending out of the conductive layer 211 should not be too large. For example, the length of the electrolyte gel layer 212 extending out of the conductive layer 211 can be controlled within 2 mm.

[0142] In combination with the foregoing, the insulating layer 213 and the electrolyte layer 212 can form an overlapping relationship, which can prevent the conductive layer 211 from contacting the metal battery compartment 100.

[0143] In this first type of embodiment, the conductive layer 211 can be connected to the back side 222, the long side 223 and part of the front side 221 of the battery cell 220, so the length dimension of the conductive layer 211 can be the same as the length dimension of the battery cell 220 (to prevent contact with the metal battery compartment 100, the length dimension of the conductive layer 211 can be slightly shorter than the length dimension of the battery cell 220), and the width dimension of the conductive layer 211 needs to be greater than the sum of the width dimension and the thickness dimension of the battery cell 220, so that the conductive layer 211 can cover the back side 222 of the battery cell 220 and extend from the long side 223 to the front side 221 of the battery cell 220.

[0144] In the above description, reference may be made to Figure 8 The length dimension of the battery cell 220 refers to the dimension of the battery cell 220 along the X direction, the width dimension of the battery cell 220 refers to the dimension of the battery cell 220 along the Y direction, and the thickness dimension of the battery cell 220 refers to the dimension of the battery cell 220 along the Z direction.

[0145] In this first type of embodiment, the electrolytic glue layer 212 can adopt an integral structure, the length dimension of the electrolytic glue layer 212 can be the same as the length dimension of the battery cell 220, and the width dimension of the electrolytic glue layer 212 can be the same as the width dimension of the battery cell 220, so that the electrolytic glue layer 212 can be bonded to the bottom wall 102 of the recessed area 101.

[0146] Fig.16 The schematic diagram shows the installation of a mounting and disassembly structure on a battery cell according to an embodiment of the present application. Figure 1 ; Fig.17 The schematic diagram shows the installation of a mounting and disassembly structure on a battery cell according to an embodiment of the present application. Figure 2 ; Fig.18 The schematic diagram shows the installation of a mounting and disassembly structure on a battery cell according to an embodiment of the present application. Figure 3 .

[0147] Can be combined with reference Figure 8 , Figures 16 to 19The installation of the assembly and disassembly structure 210 on the battery cell 220 can be divided into the following four steps: Step 1, please refer to Fig.16 The conductive layer 211 is attached to the back side 222 of the battery cell 220 and the connecting portion 2112 and part of the contact portion 2111 of the conductive layer 211 extend from one side of the battery cell 220. The length of the extended contact portion 2111 needs to be slightly larger than the thickness of the battery cell 220. Step 2, please refer to Fig.17 , the electrolytic glue layer 212 is attached to the contact portion 2111, and the size of the electrolytic glue layer 212 corresponds to the size of the back side 222 of the battery cell 220; step three, please refer to Fig.18 , bend the conductive layer 211 extending out of the battery cell 220 in step 1 and attach it to the long side 223 and the front face 221 of the battery cell 220, so that a portion of the contact portion 2111 can be exposed from the front face 221 of the battery cell 220; step 4, please refer to Figure 8 The insulating layer 213 is attached to the outer side of the conductive layer 211 corresponding to the long side 223 .

[0148] The above process describes the assembly of the assembly and disassembly structure 210 on the battery cell 220 in the first embodiment. After the assembly and disassembly structure 210 is assembled on the battery cell 220 , the battery 200 can be formed and placed in the metal battery compartment 100 .

[0149] When the battery 200 needs to be disassembled, the connecting portion 2112 and part of the contact portion 2111 attached to the front side 221 of the battery cell 220 can be turned up first, and then the battery 200 can be disassembled as described above. Figures 2 to 7 Perform related operations and no further elaboration is given.

[0150] In some embodiments, in order to facilitate the separation of the connection portion 2112 when a contact short circuit occurs, thereby realizing the disassembly of the battery 200, please refer to Figure 2 , Figure 8 and Fig.18 A tear opening 2112 b is also formed on the connecting portion 2112 , and the tear opening 2112 b is located between two adjacent contact portions 2111 .

[0151] The tear opening 2112b can change the structural strength of certain positions of the connecting portion 2112, and can also indicate the position on the connecting portion 2112 that needs to be split, so as to facilitate the splitting of the connecting portion 2112 to achieve the separation of each contact portion 2111. The splitting here can be achieved by tearing or cutting.

[0152] Fig.19 A front view of another assembly and disassembly structure provided according to an embodiment of the present application is shown; Fig. 20 A schematic diagram of assembling another assembly and disassembly structure and a battery cell provided according to an embodiment of the present application is shown.

[0153] In the second embodiment, please refer to Fig.19 and Fig. 20 The assembly and disassembly structure 210 adopts a special-shaped structure. Compared with the aforementioned first embodiment, the structure and size of the assembly and disassembly structure 210 have changed.

[0154] Specifically, in this second type of embodiment, the overall size of the contact portion 2111 of the conductive layer 211 is relatively small, the contact portion 2111 can cover a portion of the back side 222 of the battery cell 220, and the contact portion 2111 includes an outer contact portion and an inner contact portion, and the inner contact portion is located on the inner side of the outer contact portion.

[0155] The outer peripheral contact portion includes at least one first contact portion 2111 a , and the inner peripheral contact portion includes at least one second contact portion 2111 b . The length of the first contact portion 2111 a is longer than that of the second contact portion 2111 b .

[0156] Through the cooperation between the first contact portion 2111 a and the second contact portion 2111 b , the contact portion 2111 can cover a large area of ​​the back side 222 of the battery cell 220 .

[0157] In addition, different from the first embodiment, in the second embodiment, the size of the connection portion 2112 is smaller and its position is more flexible, which can simplify the assembly of the assembly and disassembly structure 210 and the battery cell 220.

[0158] In addition, different from the first embodiment, in the second embodiment, the assembly and disassembly structure 210 can be designed to be curved, so that the assembly and disassembly structure 210 need not be bent when being installed in the battery cell 220 .

[0159] Fig.21 The schematic diagram shows the installation of another assembly and disassembly structure on a battery cell according to an embodiment of the present application. Figure 1 ; Fig. 22 The schematic diagram shows the installation of another assembly and disassembly structure on a battery cell according to an embodiment of the present application. Figure 2 ; Fig.23 The schematic diagram shows the installation of a mounting and disassembly structure on a battery cell according to an embodiment of the present application. Figure 3 ; Fig.24 The schematic diagram shows the installation of a mounting and disassembly structure on a battery cell according to an embodiment of the present application. Figure 4 .

[0160] Can be combined with reference Figure 8 , Figure 21 to Figure 24 The installation of the assembly and disassembly structure 210 on the battery cell 220 can be divided into the following three steps: Step 1, please refer to Fig.21 and Fig. 22The conductive layer 211 is coated on the back side 222, the long side 223 and the front side 221 of the battery cell 220, the contact portion 2111 extends from the back side 222 to the front side 221, and the connecting portion 2112 is located on the front side 221 of the battery cell 220; Step 2, please refer to Fig.23 , attach the electrolyte layer 212 to the contact portion 2111 on the back side 222 of the battery cell 220; Step 3, please refer to Fig.24 , the insulating layer 213 is attached to the contact portion 2111 on the long side surface 223 of the battery cell 220 .

[0161] In this second embodiment, please refer to Fig.10 , the handle structure 300 can be set on the same side of the connecting portion 2112.

[0162] In the first and second embodiments, the assembly and disassembly structure 210 is provided with an insulating layer 213, and the insulating layer 213 is attached to the outer side of the contact portion 2111 corresponding to the long side surface 223 of the battery cell 220. Figure 1 After the battery 200 is loaded into the metal battery compartment 100, the portion of the assembly and disassembly structure 210 corresponding to the back side 222 of the battery cell 220 can ensure the stable connection of the battery 200, thereby ensuring its assembly and disassembly performance. The assembly and disassembly structure 210 only extends from the recessed area 101 from one side, which can ensure the capacity of the battery 200. The insulating layer 213 is arranged on the side where the assembly and disassembly structure 210 extends from the recessed area 101 to ensure the insulation between the conductive layer 211 and the metal battery compartment 100. It can be seen that, corresponding to the foregoing, the first and second embodiments can achieve a reasonable balance between the insulation performance of the insulating structure, the assembly and disassembly performance of the electrolyte, and the capacity of the battery 200.

[0163] The first and second embodiments described above describe two specific structures of the assembly and disassembly structure 210. It is understandable that in more embodiments, the assembly and disassembly structure 210 may have more structural forms.

[0164] Please refer to Figure 1 , Figure 8 and Fig. 20In the above embodiment, when the battery 200 is normally assembled in the metal battery compartment 100, the conductive layer 211 may include a straight section 211a, a first bent section 211b and a second bent section 211c. The first bent section 211b is bent from one end of the straight section 211a and extends in a direction perpendicular to the straight section 211a. The second bent section 211c is bent from the end of the first bent section 211b and extends in a direction parallel to the straight section 211a. The straight section 211a, The first bending section 211b and a portion of the second bending section 211c form the contact portion 2111 of the conductive layer 211, and another portion of the second bending section 211c forms the connecting portion 2112 of the conductive layer 211. The electrolyte layer 212 in the assembly and disassembly structure 210 is connected to the straight section 211a, and the insulating layer 213 is connected to the first bending section 211b. One end of the battery cell 220 is confined in a space formed by the straight section 211a, the first bending section 211b, and the second bending section 211c.

[0165] In the examples of this application, please refer to Figure 1 In order to realize reliable connection between the assembly and disassembly structure 210 and the battery cell 220, the assembly and disassembly structure 210 may further include a double-sided adhesive layer 214, which is connected to the other side of the conductive layer 211. The double-sided adhesive layer 214 and the electrolytic adhesive layer 212 are located on both sides of the conductive layer 211. The double-sided adhesive layer 214 can realize the connection between the assembly and disassembly structure 210 and the battery cell 220, and the electrolytic adhesive layer 212 can realize the connection between the assembly and disassembly structure 210 and the metal battery compartment 100, so that the battery 200 is stably installed in the metal battery compartment 100.
