[0041] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] In the related art, the battery is generally fixed in the battery compartment in two ways, one is to set a detachable connection structure between the battery and the battery compartment, and the other is that the battery and the battery compartment are non-detachable. Setting a detachable structure between the battery and the battery compartment can facilitate the replacement and maintenance of the battery, but the detachable connection structure occupies a large space, which affects the miniaturization design of the electrical device. The non-detachable connection method between the battery and the battery compartment uses double-sided tape to directly bond the battery to the battery compartment. This setting method can increase the capacity of the battery and ensure the miniaturization design of the electrical device. However, due to the strong adhesion of the double-sided tape, it is difficult for users or maintenance personnel to remove the battery. They can only remove the battery by applying a large force, which makes the battery easy to damage, is not conducive to the reuse of the battery, and also affects the efficiency of battery replacement.

[0043] In order to solve the above problems, the relevant technology uses a battery assembly and an electrical device. The battery assembly includes a battery and a partition structure. The partition structure includes a conductive layer and a conductive stripping adhesive. The conductive stripping adhesive has the characteristic of reduced viscosity when electricity is applied. When the battery compartment and the battery need to be separated, an external power supply can be used to form an electric potential difference between the two surfaces of the conductive stripping adhesive, thereby reducing the viscosity of the conductive stripping adhesive until the conductive stripping adhesive loses its viscosity. The operator can easily remove the battery from the battery compartment, reducing the risk of battery damage.

[0044] The battery assembly provided in the embodiment of the present application is described below in conjunction with the accompanying drawings. It should be noted that the battery provided in the embodiment of the present application can be a secondary battery, that is, the battery in the embodiment of the present application can be charged and discharged and recycled, and the specific type of the battery can include but is not limited to lithium batteries, etc., and the battery can be used in scenarios including but not limited to electronic products such as mobile phones and tablets, which are not specifically limited in the embodiment of the present application.

[0045] like Figures 1 to 4 As shown, the battery assembly of the embodiment of the present application includes: a battery 100 and a partition structure 200 .

[0046] The battery 100 includes a top surface 110 , a bottom surface 120 , and a plurality of side surfaces 130 located between the top surface 110 and the bottom surface 120 .

[0047] The partition structure 200 is located outside the battery 100, and the partition structure 200 includes a first conductive layer 300 and an insulating partition layer 400. Specifically, the first conductive layer 300 covers at least a portion of the bottom surface 120, at least a portion of the side surface 130, and at least a portion of the top surface 110 of the battery 100, and the insulating partition layer 400 covers the first conductive layer 300 located on the bottom surface 120 and the side surface 130, and at least a portion of the first conductive layer 300 located on the top surface 110 is exposed to the insulating partition layer 400, and at least a portion of the insulating partition layer 400 is composed of a conductive release adhesive 410.

[0048] By applying the technical solution of this embodiment, the partition structure 200 is wrapped around the outside of the battery 100, which can protect the battery 100 on the one hand, and can also bear the role of connecting the battery and the battery compartment on the other hand. The partition structure includes a first conductive layer 300 and an insulating partition layer 400. When the battery compartment 800 of the electrical device is made of conductive material, the insulating partition layer 400 can achieve the insulation effect between the first conductive layer 300 and the battery compartment 800, so as to ensure that a potential difference is formed on both sides of the conductive stripping adhesive 410 after the external power source 900 is connected.

[0049] Specifically, the first conductive layer 300 covers at least a portion of the bottom surface 120, at least a portion of the side surface 130, and at least a portion of the top surface 110 of the battery 100, that is, the first conductive layer 300 can contact the bottom surface of the battery 100, and can be bent and extended to the top surface of the battery 100, at least a portion of the first conductive layer 300 located on the top surface 110 is exposed to the insulating separation layer 400, and the first conductive layer 300 exposed to the insulating separation layer 400 can form a connection terminal connected to the external power supply 900, so that the first conductive layer 300 is conductive to the external power supply 900. At the same time, the other end of the external power supply 900 can be connected to the conductive battery compartment 800, thereby forming a conductive circuit of the external power supply, the first conductive layer 300 and the battery compartment. Since the insulating separation layer 400 is located between the first conductive layer 300 and the battery compartment 800, and at least part of the insulating separation layer 400 is composed of a conductive stripping adhesive 410, an electromotive force can be formed on both sides of the conductive stripping adhesive 410, thereby causing the conductive stripping adhesive 410 to lose its viscosity. The operator can remove the battery 100 from the battery compartment 800 together with the first conductive layer 300. Even if the first conductive layer 300 is damaged, it will not affect the structure of the battery 100, thereby ensuring the integrity of the battery 100.

[0050] It should be noted that the conductive release adhesive includes a first electrical release adhesive, a non-woven fabric, and a second electrical release adhesive that are stacked. The present application may select a conductive release adhesive that loses adhesiveness on the low potential side after power is applied, or a conductive release adhesive that loses adhesiveness on the high potential side after power is applied, or a conductive release adhesive that loses adhesiveness as a whole after power is applied.

[0051] Furthermore, if Figure 1 , Figure 3 and Figure 4As shown, the first conductive layer 300 includes a first main conductive portion 310 and a first extended conductive portion 320 connected to the first main conductive portion 310, the first main conductive portion 310 covers at least a portion of the bottom surface 120 of the battery 100, the first extended conductive portion 320 includes a first extended segment 321 covering at least a portion of the side surface 130 of the battery 100 and a second extended segment 322 covering at least a portion of the top surface 110 of the battery 100, and at least a portion of the second extended segment 322 is exposed from the insulating separation layer 400.

[0052] In the above structure, in order to enable the first conductive layer 300 to be quickly connected to the external power source 900, the first conductive layer 300 can be configured to include a first main conductive portion 310 and a first extended conductive portion 320. The top surface of the first main conductive portion 310 can be connected to the bottom surface of the battery 100, and the bottom surface of the first main conductive portion 310 can be connected to the battery compartment through a conductive release adhesive 410, thereby achieving the effect of connecting the battery 100 to the battery compartment 800, and the first extended conductive portion 320 can be bent so that the second extension section 322 is exposed to the insulating separation layer 400 and covers at least part of the top surface of the battery 100, thereby facilitating connection with the external power source 900.

[0053] It should be noted that the first conductive layer 300 may be a conductive metal sheet. The conductive metal sheet is thin, occupies a small space, has good ductility, and is easy to bend, so it can be used to process the first conductive layer 300. Exemplarily, the first conductive layer 300 may be an aluminum foil.

[0054] It should also be noted that in order to save material for the first conductive layer 300, the second extension section 322 can be set to a smaller volume. It only needs to be exposed to the insulating separation layer 400 and can be connected to the external power supply 900, and its area does not need to be too large.

[0055] Furthermore, if Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the first main conductive portion 310 includes multiple side edges, the first extended conductive portion 320 is connected to one side edge, the length of the side edge where the first extended conductive portion 320 is located is L1, and the connection length between the first extended conductive portion 320 and the side edge is L2, and L1 and L2 satisfy: L2≤1 / 2L1.

[0056] Such a configuration can ensure that the second extension section 322 has a sufficiently large area to connect to the external power source 900 , and can also reduce the area of ​​the first conductive layer 300 , thereby saving materials.

[0057] Further, the ratio of L1 to L2 can satisfy: 1 / 5≤L2 / L1≤1 / 2. If the ratio of L2 / L1 is too small, on the one hand, the connection area between the second extension section 322 and the external power supply 900 will be too small, and on the other hand, the connection strength between the first extension conductive portion 320 and the first main conductive portion 310 will be affected. If the ratio of L2 / L1 is too large, the material cost of the first conductive layer 300 will increase. Therefore, the ratio of L2 / L1 between 1 / 5 and 1 / 2 can ensure the connection effect between the first conductive layer 300 and the external power supply 900, ensure the connection strength between the first extension conductive portion 320 and the first main conductive portion 310, and reduce the material cost.

[0058] It should be noted that the insulating separation layer 400 may be completely composed of the conductive release adhesive 410 , or may be composed of the conductive release adhesive 410 and other insulating materials.

[0059] Specifically, Figure 1 and Figure 4 As shown, in some embodiments, the insulating separation layer 400 also includes an insulating protective layer 420, which is connected to the electrical stripping adhesive and together forms the insulating separation layer 400, and the insulating protective layer 420 and the electrical stripping adhesive are both adhered to the side of the first conductive layer away from the battery, and the connection between the electrical stripping adhesive and the insulating protective layer 420 is opposite to the bottom surface 120 of the battery 100.

[0060] In the above structure, the insulating protective layer 420 can protect the battery, insulate the first conductive layer 300 from the battery compartment 800, and reduce the use area of ​​the conductive stripping adhesive 410. Specifically, because the purpose of the conductive stripping adhesive 410 is to bond the first conductive layer 300 and the battery compartment, the coating area of ​​the conductive stripping adhesive 410 only needs to meet the bonding effect, and the excess part can be supplemented by the insulating separation layer 400, thereby reducing the electrolysis time of the conductive stripping adhesive 410 and reducing the cost of the battery assembly.

[0061] Specifically, the insulating protection layer 420 may be an insulating tape adhered to the battery 100 .

[0062] In some embodiments, the insulating protection layer 420 is opposite to the side surface 130 of the battery and extends to the top surface 110 and the bottom surface 120 of the battery, and at least a portion of the second extension segment 322 is exposed from the insulating protection layer 420 on the top surface 110 .

[0063] In the above structure, the insulating protection layer 420 can extend from the bottom surface 120 of the battery to the side surface 130 of the battery and then to the top surface 110 of the battery. This arrangement can provide a better protection effect for the battery 100 .

[0064] In some embodiments, the conductive release adhesive 410 covers the bottom surface 120 of the first conductive layer 300 and is butted or overlapped with the insulating protection layer 420 located on the bottom surface 120. Such a configuration can ensure the insulation effect between the first conductive layer 300 and the bottom surface of the battery compartment 800.

[0065] It should be noted that the above-mentioned “docking” refers to the contact between the edge of the insulating protective layer 420 and the edge of the conductive stripping adhesive 410 to prevent the first conductive layer 300 from directly contacting the bottom surface of the battery compartment 800 through the gap between the insulating protective layer 420 and the conductive stripping adhesive 410.

[0066] It should also be noted that the above-mentioned "overlap" refers to the overlap between the edge of the insulating protection layer 420 and the edge of the conductive release adhesive 410 in the thickness direction of the battery 100, so as to prevent the first conductive layer 300 from directly contacting the bottom surface of the battery compartment 800. For example, the width of the overlapped portion may be less than 2 mm.

[0067] like Figure 2 As shown, in some embodiments, the battery 100 includes a plurality of edges, the first main body conductive portion 310 has a plurality of edges corresponding to the edges of the battery 100, and a gap 301 is provided between the edge of the first main body conductive portion 310 and the edge of the battery 100. The provision of the gap 301 can ensure the insulation effect between the first conductive layer 300 and the battery compartment 800.

[0068] It should be noted that due to the design of the gap 301, the edge of the conductive release adhesive 410 slightly exceeds the edge of the first conductive layer 300. The excess portion cannot be effectively electrolyzed and its viscosity remains. However, compared with the entire conductive release adhesive 410, the adhesion of the gap portion is very small. The battery 100 can be removed by pulling up the insulating protective layer 420 or the second extension section with a relatively small pulling force.

[0069] like Figure 1 As shown, in some embodiments, a first adhesive layer 500 is disposed between the bottom surface 120 of the battery 100 and the first conductive layer 300 , so as to ensure the bonding effect between the battery 100 and the first conductive layer 300 .

[0070] In some cases, the battery compartment 800 of the electrical device is made of insulating material. In order to adapt to the battery compartment 800 of insulating material, such as Figures 5 to 7 As shown, in some embodiments, the separation structure 200 also includes a second conductive layer 600, which is located on the side of the insulating separation layer 400 facing away from the battery, and the second conductive layer 600 covers the insulating separation layer 400 located on the bottom surface 120 of the battery 100, the insulating separation layer 400 located on the side surface 130 of the battery 100, and the second conductive layer 600 covers at least a portion of the top surface 110 of the battery 100.

[0071] In some embodiments, the second conductive layer 600 includes a second main conductive portion 610 and a second extended conductive portion 620 connected to the second main conductive portion 610, the second main conductive portion 610 covers the insulating separation layer 400 located on the bottom surface 120 of the battery 100, the second extended conductive portion 620 includes a third extension segment 621 and a fourth extension segment 622 connected to the third extension segment 621, the third extension segment 621 covers the insulating separation layer 400 located on the side surface 130 of the battery 100, and the fourth extension segment 622 covers a portion of the top surface 110 of the battery 100.

[0072] In the above structure, the insulating separation layer 400 is substantially located between the first conductive layer 300 and the second conductive layer 600, the first conductive layer 300 can be bonded to the battery 100, and the second conductive layer 600 can be bonded to the battery compartment 800, and there is an insulating separation layer including a conductive release adhesive 410 between the first conductive layer 300 and the second conductive layer 600, so that the positive and negative poles of the external power supply 900 can be connected to the first conductive layer 300 and the second conductive layer 600 respectively, so that a potential difference is formed on both sides of the conductive release adhesive 410, causing the first conductive layer 300 and the second conductive layer 600 to lose their viscosity, and the battery 100 can be smoothly taken out of the battery compartment 800.

[0073] Specifically, the second extension segment 322 of the first conductive layer 300 and the fourth extension segment 622 of the second conductive layer 600 both cover a portion of the top surface of the battery 100 , thereby facilitating the connection of the positive and negative electrodes of the external power source 900 .

[0074] like Figure 7 As shown, in some embodiments, a second adhesive layer 710 is disposed between the third extension segment 621 and the insulating separation layer 400 to further ensure the connection stability between the first conductive layer 300 and the second conductive layer 600 .

[0075] like Figure 1 As shown, the present application provides an electrical device, including a battery 100 compartment and a battery assembly arranged in the battery 100 compartment, and the battery assembly is the above-mentioned battery assembly; wherein, the battery 100 compartment is made of conductive material, and the first conductive layer 300 in the battery assembly is insulated and connected to the battery 100 compartment through an insulating separation layer 400.

[0076] In the above structure, when the battery compartment 800 of the electrical device is made of a conductive material, the battery assembly only includes one conductive layer, that is, the battery assembly only includes the first conductive layer 300. The first conductive layer 300 and the conductive battery compartment 800 together constitute a conductive member connected to the positive and negative electrodes of the external power source 900, thereby forming a potential difference on both sides of the conductive stripping adhesive 410, eliminating the stickiness of the conductive stripping adhesive 410, and then removing the battery 100.

[0077] like Figure 7 As shown, the present application provides an electrical device, including a battery 100 compartment and a battery assembly arranged in the battery 100 compartment, and the battery assembly is the above-mentioned battery assembly; wherein, the battery 100 compartment is made of insulating material, and a third adhesive layer 720 is arranged between the second conductive layer 600 in the battery assembly and the battery 100 compartment.

[0078] In the above structure, when the battery compartment 800 of the electrical device is made of insulating material, the battery assembly needs to include two conductive layers, that is, the battery assembly includes a first conductive layer 300 and a second conductive layer 600, and an insulating separation layer including a conductive release adhesive 410 is provided between the first conductive layer 300 and the second conductive layer 600. Therefore, the positive and negative electrodes of the external power supply 900 can be connected to the first conductive layer 300 and the second conductive layer 600, respectively, so that a potential difference is formed on both sides of the conductive release adhesive 410, causing the first conductive layer 300 and the second conductive layer 600 to lose their viscosity, and the battery 100 can be smoothly taken out of the battery compartment 800.
