[0047] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0048] The fixing manner of the battery in the battery compartment is directly related to the convenience of battery replacement, the difficulty of maintenance, the space occupation and the safety of the battery. In the related art, there are mainly two ways to fix the battery: detachable connection structure and non-detachable adhesive way.

[0049] The detachable structure between the battery and the battery compartment can facilitate the replacement and maintenance of the battery. However, this structure usually occupies more space because additional connecting components such as clamps or buckles are needed, which may affect the miniaturization design of the device. In addition, frequent disassembly and installation may cause wear of the connecting components, reducing their durability. The non-detachable connection between the battery and the battery compartment uses double-sided adhesive tape to directly bond the battery in the battery compartment. This arrangement can save space, increase the capacity of the battery and ensure the miniaturization design of the electric device. However, due to the strong adhesion of the double-sided adhesive tape, it is difficult for the user or the maintenance personnel to disassemble the battery. The battery can only be removed by applying a large force, which may cause the battery to be easily damaged, not conducive to the reuse of the battery, and also affects the efficiency of battery replacement.

[0050] In order to improve the smoothness when the battery is taken out, a scheme of using conductive release adhesive to paste the battery is also designed in the related technology. The conductive release adhesive is a special material which has certain adhesion when not powered on, and can tightly bond the battery and the battery compartment. When it is necessary to separate the battery, an external power source can be applied between the two surfaces of the conductive release adhesive to form a potential difference. This potential difference will gradually reduce the adhesion of the conductive release adhesive, and eventually make it lose adhesion, so as to allow the operator to easily take out the battery from the battery compartment, reducing the risk of damaging the battery.

[0051] Therefore, in the scheme of bonding the battery by the conductive release adhesive, a conductive layer needs to be arranged on both sides of the conductive release adhesive, and the conductive layer is connected with the external power source to form a potential difference. Therefore, the conductive layer and the conductive release adhesive form a relatively complex laminated structure, causing an increase in the overall thickness of the battery assembly. In addition, when the battery is replaced and repaired, the operator also needs to peel off the conductive layer from the multi-layer structure to connect with the external power source, which also affects the efficiency of battery replacement and repair.

[0052] Therefore, in the scheme of bonding the battery by the conductive release adhesive, a conductive layer needs to be arranged on both sides of the conductive release adhesive, and the conductive layer is connected with the external power source to form a potential difference. Therefore, the conductive layer and the conductive release adhesive form a relatively complex laminated structure, causing an increase in the overall thickness of the battery assembly. In addition, when the battery is replaced and repaired, the operator also needs to peel off the conductive layer from the multi-layer structure to connect with the external power source, which also affects the efficiency of battery replacement and repair.

[0053] The battery assembly provided by the embodiments of the present application will be described below with reference to the accompanying drawings. It should be noted that the battery provided by the embodiments of the present application can be a secondary battery, i.e., the battery in the embodiments of the present application can be charged and discharged and recycled. The specific type of the battery can include but is not limited to lithium batteries, and the scenarios in which the battery can be used include but are not limited to electronic products such as mobile phones and tablet computers, and the embodiments of the present application do not make specific limitations in this regard.

[0054] As shown in FIGS. 1 and 2, the battery assembly of the embodiments of the present application includes a battery 100 and a separation structure 200. Figures 1 to 7 Figure 11 As shown in FIGS. 1 and 2, the battery assembly of the embodiments of the present application includes a battery 100 and a separation structure 200.

[0055] The battery 100 includes a top surface 110, a bottom surface 120, and a plurality of side surfaces 130 between the top surface 110 and the bottom surface 120.

[0056] ​The separation structure 200 is wrapped outside the battery 100, and the separation structure 200 comprises a first conductive layer 300 and an insulating separation layer 400. Specifically, the first conductive layer 300 covers at least part of the bottom surface 120 of the battery 100 and at least part of the side surface 130 of the battery 100; the insulating separation layer 400 comprises a separation main body part 401 and a pulling part 402 connected with the separation main body part 401, the separation main body part 401 covers and is connected with the first conductive layer 300, and the pulling part 402 is bonded to the top surface 110 of the battery 100. The pulling part 402 is configured to, when the pulling part 402 is subjected to a pulling force, separate the pulling part 402 from the upper surface of the battery 100 and separate the first conductive layer 300 of the side surface 130 of the battery 100 from the battery 100, and at least part of the insulating separation layer 400 is composed of the conductive peeling adhesive 410.

[0057] By applying the technical solution of the embodiment, the separation structure 200 is wrapped outside the battery 100, which can not only protect the battery 100, but also connect the battery and the battery compartment. The separation structure comprises the first conductive layer 300 and the insulating separation layer 400. In the case that the battery compartment 700 of the power-using device is made of conductive material, the insulating separation layer 400 can achieve the insulation effect of the first conductive layer 300 and the battery compartment 700, so as to ensure that the two sides of the conductive peeling adhesive 410 form a potential difference after the external power supply 800 is connected.

[0058] Specifically, the first conductive layer 300 covers at least part of the bottom surface 120 and at least part of the side surface 130 of the battery 100, and the insulating separation layer 400 comprises a separation body part 401 and a pulling part 402 connected to the separation body part 401, wherein the separation body part 401 can cover the first conductive layer 300, that is, the separation body part 401 can cover the first conductive layer 300 on the bottom surface 120 of the battery and the first conductive layer 300 on the side surface 130 of the battery. The pulling part 402 can be bonded to the upper surface of the battery 100. Since the pulling part 402 is connected to the separation body part 401 through the tear guide structure, when the pulling part 402 is subjected to a pulling force, the pulling part 402 is first separated from the upper surface of the battery 100, and as the pulling force continues, the pulling part 402 can be peeled off from the side surface of the battery, thereby separating the first conductive layer 300 on the side surface 130 of the battery 100 from the battery 100. At this time, the connecting end of the external power supply 800 can extend into the gap between the first conductive layer 300 and the battery 100, thereby contacting the first conductive layer 300 and realizing the conduction between the external power supply 800 and the first conductive layer 300. At the same time, the other end of the external power supply 800 can be connected to the battery compartment 700 which can conduct electricity. Since the insulating separation layer 400 is located between the first conductive layer 300 and the battery compartment 700, and at least part of the insulating separation layer 400 is composed of the conductive release adhesive 410, the two sides of the conductive release adhesive 410 can form an electromotive force, thereby causing the conductive release adhesive 410 to lose adhesion, and the operator can take out the battery 100 together with the first conductive layer 300 from the battery compartment 700. 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.

[0059] At the same time, since the first conductive layer 300 only covers the bottom surface and the side surface of the battery, and does not cover the top surface of the battery, the overall thickness of the battery assembly is reduced, thereby ensuring the miniaturization of the battery assembly.

[0060] It should be noted that the conductive release adhesive 410 comprises a first electrically releasable adhesive, a non-woven fabric and a second electrically releasable adhesive which are stacked. The conductive release adhesive can be selected to lose adhesion on the low potential side after being electrified, or can be selected to lose adhesion on the high potential side after being electrified, or can be selected to lose adhesion on the whole after being electrified.

[0061] In order to further improve the convenience of connecting the external power supply 800 with the first conductive layer 300, a tear guide structure 423 can be arranged between the separation body part 401 and the pulling part 402, so that the pulling part 402 can be separated from the separation body part 401 along the tear guide structure 423 when subjected to a pulling force, thereby driving the first conductive layer 300 bonded to the pulling part 402 to expose the gap between the battery 100 and the battery compartment 700, thereby facilitating the contact between the connecting end of the external power supply 800 and the first conductive layer 300.

[0062] Specifically, such as Figures 6 to 10 As shown, in some embodiments, a tear guide structure 423 is provided between the separating main body portion 401 and the lifting portion 402. The lifting portion 402 is configured such that when the lifting portion 402 is subjected to a lifting force, the lifting portion 402 separates from the separating main body portion 401 along the tear guide structure 423, exposing the first conductive layer 300 located on the side surface 130 of the battery 100 to the top surface 110 of the battery 100. This configuration enables a quick connection between the connection terminal of the external power supply 800 and the first conductive layer 300.

[0063] The specific configuration of the tear guide structure is explained below with reference to the attached diagram.

[0064] like Figures 6 to 10 As shown, in some embodiments, the lifting portion 402 is included in a first direction (the width direction of the battery 100, i.e.) Figure 6 The tear guide structure 423 includes a first tear guide portion 4231 and a second tear guide portion 4232, which are respectively disposed on opposite edges in the x direction. The first end of the first tear guide portion 4231 is located at the first edge, and the second end of the first tear guide portion 4231 extends to the side 130 of the battery 100. The first end of the second tear guide portion 4232 is located at the second edge, and the second end of the second tear guide portion 4232 extends to the side of the battery.

[0065] When a pulling force is applied to the lifting part 402, the lifting part 402 first separates from the separating body part 401 along the first tear guide part 4231 and the second tear guide part 4232, so that the first tear guide part 4231 and the second tear guide part 4232 are torn to the side 130 of the battery 100. At this time, the lifting part 402 can separate the first conductive layer 300 from the side 130 of the battery 100, so that the connection end of the external power supply 800 can be connected to the first conductive layer 300.

[0066] Furthermore, such as Figure 6 As shown, the second end of the second tear guide 4232 extends toward the second end of the first tear guide 4231 and is spaced apart from the second end of the first tear guide 4231.

[0067] When the first tear guide 4231 and the second tear guide 4232 tear to the side 130 of the battery 100, the direction of the pulling force is changed, and the second edge of the lifting part 402 is pulled upward, so that the second end of the second tear guide 4232 tears toward the second end of the first tear guide 4231, thereby realizing the twisting of the lifting part 402. At this time, the lifting part 402 can extend the first conductive layer 300 from the top surface 110 of the battery 100, so that the connection end of the external power supply 800 can be connected to the first conductive layer 300.

[0068] Specifically, the second tear guide 4232 includes a first tear segment parallel to the first tear guide 4231 and a second tear segment set at an angle to the first tear segment. The second tear segment extends toward the second end of the first tear guide 4231, thereby cracking when the lifting part 402 is subjected to tension, thereby realizing the torsion of the lifting part 402.

[0069] It should be noted that in some embodiments, the tear-guiding structure includes a tear line, and the structural strength of the insulating separator 400 at the tear line is less than the structural strength of the insulating separator 400 outside the tear line. In the above structure, the tear line can be a dotted line, which is simple in structure and easy to process. The tear line can regulate the path of separation between the lifting part 402 and the separating body part 401, thereby guiding the tearing of the lifting part 402.

[0070] The specific structure of the first conductive layer is described below with reference to the accompanying drawings.

[0071] like Figure 6 , Figure 7 and Figure 10 As shown, in some embodiments, the first conductive layer 300 includes a first main conductive portion 310 and a first extended conductive portion 320. The first main conductive portion 310 covers at least a portion of the bottom surface 120 of the battery 100 and is bonded to the bottom surface 120 of the battery through a first adhesive layer 510. The first extended conductive portion 320 is located on the side surface 130 of the battery 100 and does not extend to the top surface 110 of the battery, thereby avoiding an increase in the overall thickness of the battery assembly. While ensuring the miniaturization of the battery assembly, it also facilitates the connection of the first conductive layer 300 to an external power source.

[0072] It should also be noted that the first extended conductive portion 320 includes a first extended strip 321 and a first connecting portion 322 connecting the first extended strip 321 and the first main conductive portion 310. The length of the first connecting portion 322 in the first direction is less than the length of the first extended strip 321 in the first direction. The lifting portion 402 is disposed at the end of the first extended strip 321 away from the first connecting portion.

[0073] In the above structure, the top surface of the first main conductive part 310 can be connected with the bottom surface of the battery 100, and the bottom surface of the first main conductive part 310 can be connected with the battery compartment through the conductive stripping glue 410, so as to realize the effect of connecting the battery 100 in the battery compartment 700. The first extension conductive part 320 includes a first extension strip 321 and a first connecting part 322, and the first extension strip 321 is connected with the first main conductive part 310 through the first connecting part 322. Since the length of the first connecting part 322 in the first direction is less than the length of the first extension strip 321 in the first direction, the end of the first extension strip 321 away from the first connecting part 322 forms a free end, and the free end of the first extension strip 321 can move with the pulling part 402, so as to realize the state that the first extension strip 321 is exposed to the top surface 110 of the battery, and further facilitate the connection between the external power supply 800 and the first conductive layer 300.

[0074] Specifically, when a pulling force is applied to the pulling part 402, the pulling part 402 is first separated from the separation main body part 401 along the first tearing guide part 4231 and the second tearing guide part 4232. When the first tearing guide part 4231 and the second tearing guide part 4232 are cracked to the side surface 130 of the battery 100, the direction of the pulling force is changed, the second edge of the pulling part 402 is pulled upward, the second end of the second tearing guide part 4232 is cracked toward the second end of the first tearing guide part 4231, so as to realize the torsion of the pulling part 402. At this time, the pulling part 402 can take the first extension strip 321 away from the side surface 130 of the battery, and extend outward to the top surface 110 of the battery, so as to expose the first extension strip 321 to the top surface 110 of the battery, and facilitate the connection between the connection end of the external power supply 800 and the first conductive layer 300.

[0075] It should be noted that the first conductive layer 300 can be a conductive metal sheet. The conductive metal sheet has thin thickness, small space occupation, good ductility and easy bending, and therefore can be used to process the first conductive layer 300. Exemplarily, the first conductive layer 300 can be an aluminum foil.

[0076] The specific structure of the insulating separation layer will be described below with reference to the accompanying drawings.

[0077] As Figure 1 , Figure 5 and Figures 8 to 10As shown, in some embodiments, the insulating separator 400 further includes an insulating protective layer 420. The insulating protective layer 420 is connected to the conductive release adhesive 410 and together forms the insulating separator 400. The connection between the conductive release adhesive and the insulating protective layer 420 is located on the bottom surface 120 of the battery 100. The insulating protective layer 420 includes an insulating protective body portion 421 and a handle 422 disposed on the insulating protective body portion 421. The insulating protective body portion 421 and the handle 422 are connected by a tear guide structure. The handle 422 forms a lifting portion 402 of the insulating separator 400. The insulating protective body and the conductive release adhesive 410 form the separator body portion 401.

[0078] In the above structure, the insulating protective layer 420 serves to protect the battery, insulate the first conductive layer 300 from the battery compartment 700, and reduce the area of ​​the conductive release adhesive 410. Specifically, since the purpose of the conductive release adhesive 410 is to bond the first conductive layer 300 and the battery compartment, the coating area of ​​the conductive release adhesive 410 only needs to meet the bonding effect. The excess can be supplemented by the insulating separator layer 400, thereby reducing the electrolysis time of the conductive release adhesive 410 and reducing the cost of the battery assembly.

[0079] Specifically, the insulating protective layer 420 can be insulating adhesive paper pasted on the battery 100. Therefore, by providing a lifting part 402 on the insulating protective layer 420, the adhesive properties of the insulating adhesive paper can be utilized, so that when the lifting part 402 is torn, it can drive the first extension strip 321, thereby enriching the functionality of the insulating protective layer 420.

[0080] It should be noted that the insulating protective body 421 is attached to the side 130 of the battery 100 and extends from the side 130 to the top surface 110 and the bottom surface 120. The handle 422 is connected to the insulating protective body 421 and attached to the top surface 110 of the battery 100, forming the lifting part 402 of the insulating separator layer.

[0081] like Figure 1 As shown, in some embodiments, conductive release adhesive 410 covers the bottom surface 120 of the first conductive layer 300 and abuts or overlaps with the insulating protective layer 420 located on the bottom surface 120. This arrangement ensures the insulation effect between the first conductive layer 300 and the bottom surface of the battery compartment 700.

[0082] It should be noted that the above-mentioned "butt" refers to the contact between the edge of the insulating protective layer 420 and the edge of the conductive release adhesive 410, so as to prevent the first conductive layer 300 from directly contacting the bottom surface of the battery compartment 700 through the gap between the insulating protective layer 420 and the conductive release adhesive 410.

[0083] It is also to be noted that the "overlapping" above refers to the edge of the insulating protective layer 420 and the edge of the conductive release adhesive 410 having an overlapping portion in the thickness direction of the battery 100 to prevent the first conductive layer 300 from directly contacting the bottom surface of the battery compartment 700. Exemplarily, the width of the overlapping portion can be less than 2 mm.

[0084] Further, as shown in some embodiments, the battery 100 includes a plurality of edges, the first body conductive part 310 has a plurality of edges corresponding to the edges of the battery 100, the area of the first body conductive part 310 is smaller than the area of the bottom surface 120 of the battery 100, and each first body conductive part 310 edge has a gap 301 with the corresponding edge of the battery 100. Figure 2

[0085] In the above structure, due to the design of the gap 301, the edge of the first conductive layer 300 cannot contact the compartment wall of the battery compartment, thereby ensuring the insulation effect between the first conductive layer 300 and the battery compartment 700.

[0086] It is to be noted that such a setting can cause the edge of the conductive release adhesive 410 to exceed the edge of the first conductive layer 300, so that the excess part of the conductive release adhesive 410 cannot be effectively electrolyzed, and its adhesion is still in place. However, compared with the entire conductive release adhesive 410, the area of the non-electrolyzed part of the conductive release adhesive 410 is smaller, and a smaller pulling force can be used to remove the battery 100.

[0087] In some cases, the battery compartment 700 of the electric device is made of insulating material. In order to adapt to the battery compartment 700 made of insulating material, as shown in some embodiments, the separation structure 200 further includes a second conductive layer 600, the second conductive layer 600 covers the insulating separation layer 400 located on the bottom surface 120 of the battery 100 and the insulating separation layer 400 located on the side surface 130 of the battery 100. Figures 12 to 15

[0088] Specifically, as shown in some embodiments, the second conductive layer 600 includes a second body conductive part 610 and a second extension conductive part 620, the second body conductive part 610 covers the insulating separation layer 400 located on the bottom surface 120 of the battery 100, and the second extension conductive part 620 covers the insulating separation layer 400 located on the side surface 130 of the battery 100; the second extension conductive part 620 includes a second extension strip 621 and a second connecting part 622 connecting the second extension strip 621 and the second body conductive part 610, the length of the second connecting part 622 in the first direction is smaller than the length of the second extension strip 621 in the first direction, the pulling part 402 is arranged in the first direction with the second connecting part 622, and the pulling part 402 and the second extension strip 621 are bonded by the second adhesive layer 520. Figures 12 to 15 ​​​

[0089] In the above-mentioned 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 is capable of being bonded with the battery 100, the second conductive layer 600 is capable of being bonded with the battery compartment 700, and the first conductive layer 300 and the second conductive layer 600 have the insulating separation layer 400 including the conductive peeling adhesive 410 therebetween, so that the positive and negative poles of the external power supply 800 can be connected to the first conductive layer 300 and the second conductive layer 600 respectively, thereby forming a potential difference on both sides of the conductive peeling adhesive 410, causing the first conductive layer 300 and the second conductive layer 600 to lose adhesion, and the battery 100 can be smoothly taken out of the battery compartment 700.

[0090] Further, the first conductive layer 300 and the second conductive layer 600 have similar structures, but since the second conductive layer 600 is located on the outer side of the insulating separation layer 400 and the first conductive layer 300 is located on the inner side of the insulating separation layer 400, the size of the second conductive layer 600 is greater than that of the first conductive layer 300.

[0091] Specifically, the second conductive layer 600 includes a second main conductive part 610 and a second extension conductive part 620, the second main conductive part 610 covers the insulating separation layer 400 located on the bottom surface 120 of the battery 100, and the second extension conductive part 620 covers the insulating separation layer 400 located on the side surface 130 of the battery 100, that is, the inner side of the insulating separation layer 400 is bonded with the first extension conductive part 320, and the outer side of the insulating separation layer 400 is bonded with the second extension conductive part 620. Specifically, the pulling part 402 of the insulating separation layer 400 can be bonded with the first extension strip 321 and the second extension strip 621 at the same time, so that when the pulling part 402 is pulled out, the first extension strip 321 and the second extension strip 621 are also taken out of the gap between the battery 100 and the battery compartment 700, and then the two connection ends of the external power supply 800 can be connected to the first extension strip 321 and the second extension strip 621 respectively, thereby realizing the electrolysis of the conductive peeling adhesive 410.

[0092] As shown in Figure 1 The application further provides a power consumption device, which comprises a battery compartment 700 and a battery assembly arranged in the battery compartment 700, and the battery assembly is the above-mentioned battery assembly, wherein the battery compartment 700 is made of a conductive material, and the first conductive layer 300 in the battery assembly is arranged between the insulating separation layer 400 and the battery compartment 700.

[0093] In the above structure, when the battery compartment 700 of the electric device is made of conductive material, the battery assembly only includes one conductive layer, i.e., the battery assembly only includes the first conductive layer 300. The first conductive layer 300 and the battery compartment 700 capable of conducting electricity together constitute a conductive member connected to the positive and negative poles of the external power supply 800, thereby forming a potential difference on both sides of the conductive release adhesive 410, achieving the elimination of the adhesion of the conductive release adhesive 410, and further taking out the battery 100.

[0094] As shown in Figure 12 The application also provides an electric device, which comprises a battery compartment 700 and a battery assembly arranged in the battery compartment 700, and the battery assembly is the above-mentioned battery assembly. In the above structure, the battery compartment 700 is made of insulating material, and the second conductive layer 600 in the battery assembly is provided with a third adhesive layer 530 between the second conductive layer 600 and the battery compartment 700.

[0095] In the above structure, when the battery compartment 700 of the electric device is made of insulating material, the battery assembly needs to include two conductive layers, i.e., the battery assembly includes the first conductive layer 300 and the second conductive layer 600, and the first conductive layer 300 and the second conductive layer 600 have an insulating separation layer including the conductive release adhesive 410 therebetween. Therefore, the positive and negative poles of the external power supply 800 can be connected to the first conductive layer 300 and the second conductive layer 600, respectively, thereby forming a potential difference on both sides of the conductive release adhesive 410, causing the first conductive layer 300 and the second conductive layer 600 to lose adhesion, and the battery 100 can be smoothly taken out from the battery compartment 700.
