Description

Technical Field

[0001] This utility model relates to the field of battery structure technology, and more specifically, to a battery. Furthermore, this utility model also relates to an electrical device comprising the aforementioned battery. Background Technology

[0002] For electrical equipment such as home appliances and consumer electronics, removable batteries are a major development trend now and in the future.

[0003] Electro-release tape, as an electro-release adhesive, has high adhesive strength during use and can be easily peeled off after being powered on, thus it is suitable for battery removal.

[0004] However, in related technologies, in order to prevent the conductive layer of the electrically peelable adhesive from coming into contact with the metal battery compartment of the electrical device and causing a short circuit, it is necessary to ensure that the area of ​​the electrically peelable adhesive is larger than the area of ​​the conductive layer. This results in the part of the electrically peelable adhesive that extends beyond the conductive layer being unable to be effectively electrolyzed, making battery disassembly difficult and the battery disassembly process cumbersome.

[0005] Therefore, how to ensure that all electrolytically bonded parts are electrolyzed to facilitate battery disassembly is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a battery in which the electrically peelable adhesive can be completely electrolyzed, making the battery easy to disassemble.

[0007] Another objective of this invention is to provide an electrical device that includes the aforementioned battery, which is easy to disassemble.

The relationship between E, S, and L is: E > S / L.

[0018] And / or, the spacing between two adjacent conductive parts is F, where F > E.

[0019] Optionally, it also includes:

[0020] The second adhesive has the same thickness as the conductive layer, is coplanar with the conductive layer and does not overlap, and is disposed between the insulating layer and the battery body.

[0021] Optionally, the battery body has a top sealing edge at one end along its length direction, and a side sealing edge at the side of the battery body along its width direction, and the portion of the side sealing edge extending beyond the top of the battery body along its length direction is a first connecting portion.

[0022] The conductive layer includes:

[0023] At least two spaced conductive portions;

[0024] A connecting portion is connected to each of the conductive portions. The connecting portion is located at one end of the battery body along its length. The connecting portion includes a second straight portion, a second bent portion, a third straight portion, a third bent portion, and a fourth straight portion that are connected in sequence and form a U-shaped structure. The second straight portion and the fourth straight portion are respectively located on both sides of the top sealing edge. The third straight portion is located on the outside of the first connecting portion along the width direction. The second straight portion and the fourth straight portion do not extend beyond the battery body along the thickness direction. The fourth straight portion is the power receiving portion.

[0025] Optionally, the first connecting portion is recessed along the width direction within the portion of the side seal that does not extend beyond the top of the battery body; the third straight portion does not extend beyond the battery body along the width direction.

[0035] Any of the above-mentioned batteries;

[0037] The battery provided by this utility model has the following beneficial effects:

[0038] During use, the battery is placed in the battery compartment of the device. The battery compartment must be conductive. Since the electro-release adhesive protrudes from the insulating layer along the thickness direction away from the battery body, it adheres to the battery compartment, thus securing the battery to the compartment and ensuring battery reliability during device use. When battery removal is required, the conductive layer's contact portion and the battery compartment are connected to the positive and negative terminals of the power source, respectively. By energizing the conductive layer, the electro-release adhesive is electrolyzed. Because the conductive layer completely covers the side of the electro-release adhesive facing the conductive layer (i.e., the conductive layer fully covers the entire area of ​​the electro-release adhesive), and the area of ​​the electro-release adhesive is smaller than the area of ​​the conductive layer, with the edges of the electro-release adhesive not exceeding the edges of the conductive layer, the electro-release adhesive is effectively electrolyzed when the conductive layer is energized. This reduces the adhesive's stickiness to zero, allowing the battery to be easily removed from the battery compartment, facilitating convenient battery removal and replacement. Furthermore, since the insulating layer covers at least the portion of the conductive layer away from the battery body but not the electrically release adhesive, meaning the insulating layer covers the portion of the conductive layer away from the battery body that is not covered by the electrically release adhesive, the insulating layer provides insulation and protection for the conductive layer. This prevents the portion of the conductive layer extending beyond the electrically release adhesive from contacting the battery compartment and causing a short circuit. Additionally, the electrically release adhesive protrudes from the insulating layer, creating a gap between the insulating layer and the battery compartment. This gap allows for the placement of circuit boards in electrical devices (such as mobile phones, tablets, and laptops), improving the space utilization of the devices.

[0039] It can be seen that the battery utilizes the combined effect of the electrostripping adhesive and the insulating layer to provide insulation and protection for the battery, while ensuring that the electrostripping adhesive is completely electrolyzed, making it convenient for battery disassembly and replacement.

[0040] The electrical equipment provided by this utility model includes the above-mentioned battery and has at least the same beneficial effects as the above-mentioned battery. Attached Figure Description

Detailed Implementation

[0066] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0067] The core of this invention is to provide a battery whose electrically peelable adhesive parts can be completely electrolyzed, facilitating battery disassembly. Another core aspect of this invention is to provide an electrical device incorporating the aforementioned battery, with convenient battery disassembly.

[0068] Please refer to Figure 1 and Figure 2This utility model provides a battery, including a battery body 1, a conductive layer 2, an electrically removable adhesive 3, and an insulating layer 4. The conductive layer 2 is disposed on a first surface in the thickness direction of the battery body 1, and the conductive layer 2 has a contact portion 23. The electrically removable adhesive 3 is disposed on the side of the conductive layer 2 away from the battery body 1, and the conductive layer 2 completely covers the side of the electrically removable adhesive 3 facing the conductive layer 2. The area of ​​the conductive layer 2 is larger than the area of ​​the electrically removable adhesive 3. The insulating layer 4 is connected to the battery body 1, and the insulating layer 4 at least covers the portion of the conductive layer 2 away from the battery body 1, but does not cover the electrically removable adhesive 3 and the contact portion 23. Along the thickness direction away from the battery body 1, the height of the electrically removable adhesive 3 protruding from the surface of the conductive layer 2 is greater than the height of the insulating layer 4 protruding from the surface of the conductive layer 2.

[0069] Please refer to Figure 3 and Figure 4 In use, the battery is placed into the battery compartment 7 of the device 8. The battery compartment 7 must be conductive. Since the electro-release adhesive 3 protrudes from the insulating layer 4 along the thickness direction away from the battery body 1, it can be bonded to the battery compartment 7. Thus, the electro-release adhesive 3 can be used to fix the battery to the battery compartment 7, ensuring the reliability of the battery when the device 8 is in use. In addition, the electro-release adhesive 3 protrudes from the insulating layer 4, which can form a gap between the insulating layer 4 and the battery compartment 7. This is beneficial for setting up circuit boards in the device (such as mobile phones, tablets, laptops, etc.) within the gap, improving the space utilization of the device. When it is necessary to remove the battery, the conductive layer 2's contact part 23 and the battery compartment 7 are connected to the positive and negative terminals of the power supply, respectively. By energizing the conductive layer 2, the electro-release adhesive 3 can be electrolyzed. Since the conductive layer 2 completely covers the side of the electrically released adhesive 3 facing the conductive layer 2, that is, the conductive layer 2 fully covers the entire area of ​​the electrically released adhesive 3, the area of ​​the electrically released adhesive 3 is smaller than the area of ​​the conductive layer 2, and the edge of the electrically released adhesive 3 does not extend beyond the edge of the conductive layer 2, the electrically released adhesive 3 can be effectively electrolyzed when the conductive layer 2 is energized, reducing the adhesiveness of the electrically released adhesive 3 to zero. This allows the battery to be easily removed from the battery compartment 7, enabling convenient battery removal and replacement. Furthermore, since the insulating layer 4 covers at least the portion of the conductive layer 2 away from the battery body 1, but does not cover the electrically released adhesive 3, that is, the insulating layer 4 covers the portion of the conductive layer 2 away from the battery body 1 that is not covered by the electrically released adhesive 3, the insulating layer 4 provides insulation and protection for the conductive layer 2, preventing the portion of the conductive layer 2 extending beyond the electrically released adhesive 3 from contacting the battery compartment 7 and causing a short circuit.

[0070] Therefore, the battery provided in this embodiment of the present invention utilizes the combined effect of the electrostripping adhesive 3 and the insulating layer 4 to provide insulation and protection for the battery while ensuring that the electrostripping adhesive 3 is completely electrolyzed, making it convenient for battery disassembly and replacement.

[0071] It should be noted that the specific structure of the electrically released adhesive 3 is not limited in this embodiment. The electrically released adhesive 3 can be an electrically released tape or an electrically released adhesive layer, such as an electrically released glue layer, as long as its adhesiveness can be reduced under electrical stimulation. Specifically, the electrically released adhesive 3 includes a first electrically released adhesive layer, a non-woven fabric, and a second electrically released adhesive layer stacked together. This application can select an electrically released adhesive 3 that loses its adhesiveness on the low potential side after the contact part 23 is energized, or an electrically released adhesive 3 that loses its adhesiveness on the high potential side after the contact part 23 is energized, or an electrically released adhesive 3 that loses its adhesiveness entirely after the contact part 23 is energized.

[0072] In addition, this embodiment does not limit the specific connection method between the conductive layer 2 and the battery body 1, as long as it can ensure that the conductive layer 2 and the battery body 1 are relatively fixed.

[0073] like Figure 1 As shown, in some embodiments, a first adhesive 5 is provided between the conductive layer 2 and the battery body 1.

[0074] In other words, in this embodiment, the conductive layer 2 is adhered to the battery body 1 using the first adhesive 5. The presence of the first adhesive 5 ensures the reliable fixation of the conductive layer 2 to the battery body 1. Furthermore, during battery assembly, the conductive layer 2, the insulating layer 4, and the electrically release adhesive 3 can be assembled layer by layer. For example, firstly, as... Figure 5 As shown, the conductive layer 2 is adhered to the battery body 1 via the first adhesive 5, and then the insulating layer 4 is connected to the battery body 1 (e.g., Figure 6 (as shown), and then, the electrically peelable adhesive 3 is attached to the conductive layer 2 (as shown). Figure 7 (As shown).

[0075] It should be noted that the first adhesive 5 is not specifically limited in this embodiment, as long as it can connect the conductive layer 2 to the battery body 1. For example, the first adhesive 5 can be double-sided tape or glue.

[0076] Additionally, to improve battery energy density, please refer to... Figure 8 In other embodiments, the conductive layer 2 is directly attached to the battery body 1, and the conductive layer 2 is fixed to the battery body 1 by the insulating layer 4.

[0077] In other words, this embodiment eliminates the first adhesive 5 between the conductive layer 2 and the battery body 1. The conductive layer 2 is fixed to the battery body 1 by connecting the insulating layer 4 to both the conductive layer 2 and the battery body 1. Essentially, there are no adhesives on either side of the conductive layer 2. A second adhesive 6 is provided on the side of the insulating layer 4 facing the battery body 1. This second adhesive 6 is used to fix the insulating layer 4 to both the conductive layer 2 and the battery body 1. Once the insulating layer 4 is fixed to the battery body 1, the conductive layer 2 is also fixed to the battery body 1. This reduces the thickness of the battery, which is beneficial for increasing the battery's energy density.

[0078] For easier assembly, please refer to [reference needed]. Figure 9 In some embodiments, the conductive layer 2, the insulating layer 4, and the electrically peelable adhesive 3 are connected as a single unit, that is, the conductive layer 2 is attached to the insulating layer 4 for the side facing the battery body 1 (e.g., Figure 10 As shown), and the electro-peel adhesive 3 is attached to the conductive layer 2 for the side opposite to the battery body 1 (as shown). Figure 12 As shown), the conductive layer 2, the insulating layer 4, and the electrically peelable adhesive 3 form a single unit (as shown). Figure 11 As shown), it is assembled with the battery body 1.

[0079] In addition, the above embodiments do not limit the specific arrangement of the conductive layer 2 and the electrically peelable adhesive 3, as long as the electrically peelable adhesive 3 can provide sufficient adhesive force for the battery so that the battery can be reliably fixed to the battery compartment 7.

[0080] Please refer to Figure 13 In some embodiments, the electrically peelable adhesive 3 includes at least two spaced electrically peelable adhesive portions 31, and the conductive layer 2 includes at least two spaced conductive portions 21, each conductive portion 21 completely covering at least one electrically peelable adhesive portion 31; the insulating layer 4 is an integral structure, and the insulating layer 4 has an opening 411 at the position corresponding to the electrically peelable adhesive portion 31 (please refer to...). Figure 2 , Figure 6 and Figure 7 The electro-peelable adhesive portion 31 is provided in the corresponding opening 411.

[0081] In other words, the electro-removable adhesive 3 in this embodiment has a multi-piece distributed structure. The electro-removable adhesive 3 includes at least two electro-removable adhesive portions 31. The two or more electro-removable adhesive portions 31 are independent of each other and not connected to each other. They are distributed at multiple positions on the first surface of the battery body 1 to be applied to different usage scenarios. In addition, the conductive layer 2 also has a multi-piece distributed structure. The conductive layer 2 includes at least one conductive portion 21 to adapt to the distribution of the electro-removable adhesive 3. This can save the overall area of ​​the conductive layer 2. At the same time, the conductive portion 21 can correspond one-to-one with the electro-removable adhesive portion 31, that is, one conductive portion 21 completely covers one electro-removable adhesive portion 31, or one conductive portion 21 can correspond to at least two electro-removable adhesive portions 31, that is, one conductive portion 21 completely covers at least two electro-removable adhesive portions 31, as long as each electro-removable adhesive portion 31 can be completely electrolyzed. In addition, this embodiment provides an opening 411 at the position of the insulating layer 4 corresponding to the electrically peelable adhesive portion 31 to avoid the electrically peelable adhesive portion 31, so that the electrically peelable adhesive portion 31 is attached to the conductive portion 21 through the opening 411. This structure is beneficial for the overall installation of the insulating layer 4 and also makes it easier to ensure the relative positional relationship between the edge of the electrically peelable adhesive portion 31 and the edge of the insulating layer 4, making battery assembly convenient.

[0082] Furthermore, when the conductive layer 2 is fixed to the battery body 1 by the insulating layer 4, in order to ensure that there is sufficient effective bonding area between the conductive layer 2 and the insulating layer 4, in some embodiments, the distance between a single conductive part 21 and the corresponding edge of the corresponding opening 411 is E (e.g., Figure 13 As shown), the sum of the areas of the electrically peelable adhesive portions 31 completely covered by a single conductive portion 21 is S, and the sum of the perimeters of the electrically peelable adhesive portions 31 completely covered by a single conductive portion 21 is L. The relationship between E, S, and L is: E > S / L; and / or, the distance between two adjacent conductive portions 21 is F (as shown). Figure 13 As shown), F > E.

[0083] It is understood that the above relationship E > S / L represents the relationship between a single conductive part 21 and its corresponding electrically peelable adhesive part 31 and corresponding opening 411. When the conductive part 21 is fully covered by one electrically peelable adhesive part 31, the insulating layer 4 corresponds to one opening 411 for the conductive part 21. In this case, the distance between the edge of the conductive part 21 and the corresponding edge of the opening 411 is E, S is the area of ​​one electrically peelable adhesive part 31 corresponding to the conductive part 21, and L is the perimeter of one electrically peelable adhesive part 31 corresponding to the conductive part 21. When the conductive part 21 is fully covered by at least two electrically peelable adhesive parts 31, the insulating layer 4 corresponds to at least two openings 411 for the conductive part 21. In this case, the distance between the edge of the conductive part 21 and the corresponding edge of each opening 411 is E, S is the sum of the areas of all electrically peelable adhesive parts 31 corresponding to the conductive part 21, and L is the sum of the perimeters of all electrically peelable adhesive parts 31 corresponding to the conductive part 21. Furthermore, the spacing F between two adjacent conductive parts 21 is greater than E, which helps to ensure that there is a sufficient effective bonding area between the insulating layer 4 and the battery body 1, thereby increasing the effective bonding area between the insulating layer 4 and the conductive layer 2 and the battery body 1 respectively, and improving the reliability of fixing the conductive layer 2 and the battery body 1.

[0084] Additionally, when the conductive layer 2 is fixed to the battery body 1 via the insulating layer 4, to improve the reliability of the connection between the conductive layer 2 and the battery body 1, please refer to... Figure 14 In some embodiments, the battery further includes a second adhesive 6, the thickness of which is the same as the thickness of the conductive layer 2. The second adhesive 6 is coplanar with the conductive layer 2 and does not overlap. The second adhesive 6 is disposed between the insulating layer 4 and the battery body 1.

[0085] In other words, in this embodiment, a second adhesive member 6 is provided between the insulating layer 4 at a position that does not correspond to the conductive layer 2 and the position where the insulating layer 4 faces the plane where the conductive layer 2 is located and the battery body 1. That is, the second adhesive member 6 is on the same plane as the conductive layer 2 and the second adhesive member 6 avoids the conductive layer 2. This is beneficial to improve the flatness of the insulating layer 4 and improve the connection effect between the insulating layer 4 and the conductive layer 2 and the battery body 1 respectively.

[0086] Furthermore, the above embodiments do not limit the specific location of the contact portion 23 of the conductive layer 2, as long as the contact portion 23 can be easily connected to power when the battery needs to be removed. Please refer to... Figure 15 , Figure 16 and Figure 17In some embodiments, the battery body 1 has a top sealing edge 11 at one end along its length direction and a side sealing edge 12 at the side of its width direction. The portion of the side sealing edge 12 that extends beyond the top of the battery body 1 along its length direction is a first connecting portion 122. The conductive layer 2 includes at least two spaced conductive portions 21 and connecting portions 22 that are respectively connected to each conductive portion 21. The connecting portion 22 is located at one end along the length direction of the battery body 1. The connecting portion 22 includes a second straight portion 221, a second bent portion 222, a third straight portion 223, a third bent portion 224, and a fourth straight portion 225 that are connected in sequence and form a U-shaped structure. The second straight portion 221 and the fourth straight portion 225 are respectively located on both sides of the top sealing edge 11. The third straight portion 223 is located on the outside of the first connecting portion 122 along its width direction. The second straight portion 221 and the fourth straight portion 225 do not extend beyond the battery body 1 along its thickness direction. The fourth straight portion 225 is a contact portion 23.

[0087] Understandably, the second straight portion 221 and the fourth straight portion 225 are located on both sides of the top sealing edge 11, which helps to utilize the head space of the battery body 1 where the top sealing edge 11 is located. This prevents the second straight portion 221 and the fourth straight portion 225 from extending beyond the battery body 1 along its thickness direction, thus ensuring the size of the battery body 1 and the energy density of the battery. In addition, the fourth straight portion 225 forms the power receiving portion 23. When the battery needs to be removed, it is only necessary to flatten the fourth straight portion 225 towards the direction of the third bending portion 224, which facilitates the connection of the fourth straight portion 225 to an external power source.

[0088] Furthermore, in some embodiments, the first connecting portion 122 is recessed in the width direction of the battery body 1 and does not extend beyond the top of the side sealing edge 12; the third straight portion 223 does not extend beyond the battery body 1 in the width direction of the battery body 1.

[0089] In other words, in this embodiment, the first transition portion 121 and the first connecting portion 122 are formed by bending the portion of the side sealing edge 12 that extends beyond the top of the battery body 1 along the length direction. The first connecting portion 122 and the portion of the side sealing edge 12 that does not extend beyond the top of the battery body 1 form a stepped structure, which is equivalent to forming a recess between the outer side of the first connecting portion 122 along the width direction and the outer side of the side sealing edge 12 along the width direction. Thus, when the second straight portion 221 of the connecting portion 22 extends along one side of the top sealing edge 11 along the width direction to the end of the top sealing edge 11 near the first connecting portion 122, the third... The straight portion 223 bypasses the outside of the first connecting portion 122. When the third straight portion 223 extends along the outside of the first connecting portion 122 and along the thickness direction of the battery body 1 to the end of the first straight portion 122, the third bending portion 224 causes the fourth straight portion 225 to extend in a direction parallel to the top sealing edge 11 (i.e., the width direction). Since the first straight portion 122 is recessed in the width direction of the side sealing edge 12 and does not extend beyond the top of the battery body 1, when the third straight portion 223 bypasses the outside of the first connecting portion 122, it is beneficial to avoid the third straight portion 223 extending beyond the battery body 1 in the width direction of the battery body 1.

[0090] In addition, the specific structure of the insulating layer 4 is not limited in the above embodiments, as long as the insulating layer 4 can cover the part of the conductive layer 2 that extends beyond the electrically peelable adhesive 3 and is away from the battery body 1.

[0091] Please refer to Figure 18 In some embodiments, the insulating layer 4 is disposed on the first surface of the battery body 1. That is, in this embodiment, the insulating layer 4 is disposed only on the first surface of the battery body 1 where the conductive layer 2 is disposed, and the insulating layer 4 does not extend to other surfaces of the battery body 1, which helps to ensure the size of the battery itself.

[0092] In other embodiments, to improve the reliability of the connection between the insulating layer 4 and the battery body 1, such as... Figure 9 As shown, the insulating layer 4 includes a first insulating portion 41, a second insulating portion 42, and a third insulating portion 43. The first insulating portion 41 is disposed on a first surface of the battery body 1. The second insulating portion 42 is connected to the first insulating portion 41 and is disposed on at least one side of the battery body 1 along its width direction and / or length direction. The third insulating portion 43 is connected to the second insulating portion 42 and is disposed on a second surface of the battery body 1 along its thickness direction.

[0093] In other words, in this embodiment, the insulating layer 4 is not only located on the first surface of the battery body 1 where the conductive layer 2 is located, but also extends to the side surface of the battery body 1 along the width direction and / or the side surface along the length direction, and further extends to the second surface of the battery body 1 away from the first surface along the width direction. Thus, when attaching the insulating layer 4, firstly, the insulating layer 4 is attached to the first surface of the battery body 1. Then, the insulating layer 4 is folded along the side wall of the battery body 1 along the width direction and / or length direction, so that the second insulating portion 42 covers the side wall of the battery body 1 along the width direction and / or length direction. Then, the insulating layer 4 is folded along the second surface of the battery body 1 along the thickness direction, so that the third insulating portion 43 covers a portion of the second surface of the battery body 1 near the edge along the thickness direction. This improves the reliability of the connection between the insulating layer 4 and the battery body 1.

[0094] Additionally, it is understandable that in order for the electro-peelable adhesive 3 to be completely and effectively electrolyzed, it is necessary to ensure that the electro-peelable adhesive 3 does not overlap with the insulating layer 4. Please refer to [reference needed]. Figure 20 In some embodiments, a gap B exists between the insulating layer 4 and the electrically released adhesive 3, the gap B being 0-1 mm. That is, the distance from the edge of the electrically released adhesive 3 to the corresponding edge of the insulating layer 4 is 0-1 mm. When the insulating layer 4 has an opening 411 and the electrically released adhesive 3 is disposed within the opening 411, the distance between the edge of the electrically released adhesive 3 and the edge of the opening 411 is 0-1 mm. Although this gap causes a slight exposure of the conductive layer 2, because the gap is small and the thickness of the insulating layer 4 and the electrically released adhesive 3 causes the conductive layer 2 to be raised away from the battery compartment 7, direct contact between the conductive layer 2 and the battery compartment 7 can be avoided, preventing short circuits.

[0095] Further, please refer to Figure 19 In some embodiments, the distance between the edge of the insulating layer 4 covering the conductive layer 2 and the edge of the conductive layer 2 is A, where A ranges from 1 to 2 mm. That is, the width of the insulating layer 4 covering the conductive layer 2 is greater than 1 mm and less than 2 mm. When the insulating layer 4 has an opening 411 and the electrically released adhesive 3 is disposed within the opening 411, the distance from the edge of the opening 411 to the edge of the conductive layer 2 is greater than 1 mm and less than 2 mm. This ensures that the insulating layer 4 can effectively bond with the conductive layer 2, improving the reliability of the fixing of the conductive layer 2 to the battery body 1 and the overall adhesion strength.

[0096] Additionally, to ensure effective adhesion between the electro-peel adhesive 3 and the battery compartment 7, please refer to... Figure 21 and Figure 22In some embodiments, the height by which the electrically released adhesive 3 protrudes from the surface of the conductive layer 2 in the thickness direction away from the battery body 1 is greater than the height by which the insulating layer 4 protrudes from the surface of the conductive layer 2 by 0.01 to 1 mm. That is, the thickness of the electrically released adhesive 3 is at least 0.01 mm thicker than the thickness of the insulating layer 4. This helps to ensure that the electrically released adhesive 3 protrudes from the insulating layer 4 in the thickness direction away from the battery body 1, thereby ensuring that the electrically released adhesive 3 can be effectively bonded to the battery compartment 7. On the other hand, if the thickness of the electrically released adhesive 3 is too thick than the thickness of the insulating layer 4, for example, if the thickness of the electrically released adhesive 3 is more than 1 mm thicker than the thickness of the insulating layer 4, it will result in an excessively large gap between the insulating layer 4 and the battery compartment 7, which will easily lead to a waste of structural space and make it difficult to fix the battery stably.

[0097] Furthermore, in some embodiments, the thickness of the electrically peelable adhesive 3 ranges from 0.05 to 2 mm, and the thickness of the insulating layer 4 ranges from 0.035 to 2 mm.

[0098] In addition to the aforementioned battery, this utility model also provides an electrical device that includes the battery disclosed in the above embodiments. The electrical device has a conductive battery compartment 7, and the battery is disposed within the battery compartment 7. It should be noted that this embodiment does not limit the specific type of electrical device. For example, the electrical device includes, but is not limited to, mobile phones, tablet computers, laptops, heat sinks, and monitors. For the structure of other parts of the electrical device, please refer to relevant technologies; further details are omitted here.

[0099] The key point of this embodiment is that the battery disclosed in any of the above embodiments at least includes the beneficial effects of the battery described above. It is understood that during the assembly of the electrical device, the battery is placed in the battery compartment 7, and the electrically release adhesive 3 is bonded to the battery compartment 7. The electrically release adhesive 3 is used to fix the battery to the battery compartment 7, ensuring the reliability of battery power supply during the use of the electrical device. When the battery needs to be disassembled and repaired, it is only necessary to connect the conductive layer 2 of the battery and the battery compartment 7 to the positive and negative terminals of the power supply, respectively. By energizing the conductive layer 2, the electrically release adhesive 3 can be electrolyzed, thereby allowing the battery to be easily separated from the battery compartment 7. At this time, the battery can be easily removed from the battery compartment 7, facilitating battery disassembly.
