Description

Technical Field

[0001] This disclosure relates to a battery strip and a method for attaching a battery strip. Background Technology

[0002] Unlike primary batteries, which are not designed to be (re)charged, secondary (or rechargeable) batteries are designed to be discharged and recharged. Low-capacity secondary batteries are used in portable small electronic devices such as smartphones, feature phones, laptops, digital cameras, and camcorders, while high-capacity secondary batteries are widely used as power sources to drive motors in hybrid and electric vehicles and as power sources for storing electricity (e.g., household and / or utility-scale power storage). A secondary battery typically includes an electrode assembly containing positive and negative electrodes, a housing that houses the electrode assembly, and electrode terminals connected to the electrode assembly.

[0003] The information disclosed in this background section is intended to enhance the understanding of the background art of this disclosure, and therefore may contain information that does not constitute related (or prior art). Summary of the Invention

[0004] This disclosure aims to provide a battery strip and a battery sticker method to solve the problems described herein.

[0016] According to embodiments of the present disclosure, a battery tape method is provided, the battery tape method comprising: providing a battery tape including a first member, a pair of second members, and a pair of third members; placing the first member on a first surface of a battery; bending the pair of second members along a first side surface of the battery in a first direction of the battery, and applying tension to the pair of second members in the first direction; overlapping and adhering the pair of second members to a second surface of the battery opposite to the first surface, such that a pull indicator line formed on one of the pair of second members overlaps with a tension indicator line formed on the other of the pair of second members; bending each of the pair of third members along a second side surface of the battery in a second direction of the battery perpendicular to the first direction; and adhering at least a portion of the third members to the second surface of the battery.

[0017] Pull indicator lines for a pair of second members can be formed on opposite sides of the pair of second members in a second direction, and break when tension is applied.

[0018] In the overlapping and adhesion of a pair of second components, the pull indicator lines that break by applying tension intersect each other, and the pair of second components can adhere to the second surface.

[0019] The pull indicator line can be formed on a pair of second members as a cutting line cut along a second direction.

[0020] The pull indicator line can be formed as a dashed line extending in a second direction on a pair of second members.

[0021] The length of the pull indicator line may be 30% or more of the width of the second member in the second direction, or the length of the pull indicator line may be 50% or less of the width of the second member in the second direction, or the length of the pull indicator line may be 30% to 50% of the width of the second member in the second direction.

[0026] According to embodiments of this disclosure, a pair of second members overlap each other to attach to the battery, thereby enhancing the adhesion between the battery band and the battery. Therefore, in cases such as when an electronic device is dropped, the likelihood of the battery detaching from the battery band can be minimized.

[0027] According to an embodiment, the pull indicator lines of the second component can intersect each other and adhere to the battery, thereby enhancing the adhesion between the battery band and the battery. Therefore, this function prevents battery movement, thus ensuring battery stability.

[0028] According to an embodiment, by forming a non-adhesive area over the entire area of ​​the first component and a portion of the second and / or third component, problems such as twisted sealing or difficulty in removing the battery band can be solved.

[0029] According to an embodiment, a non-adhesive area is formed along the edge of the second and / or third member to prevent problems such as the battery strap detaching from the battery during a drop of the electronic device or noise occurring between the battery strap and the side surface of the battery, while improving the ease of battery removal. Thus, the user can easily detach the battery strap.

[0030] However, the aspects and features of this disclosure are not limited to those described above, and other aspects and features not mentioned will be clearly understood by those skilled in the art from the detailed description described below. Attached Figure Description

[0048] Some embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The terms or words used in this specification and claims should not be construed as having a general or dictionary meaning, but should be interpreted as consistent with the technical spirit of this disclosure, based on the principle that the inventor is capable of being his / her own lexicographer to appropriately define the terms and concepts in order to best describe his / her invention.

[0049] The embodiments described in this specification and the configurations shown in the accompanying drawings are only some of the embodiments of this disclosure and do not represent all the technical spirit, aspects, and features of this disclosure. Therefore, it should be understood that various equivalents and modifications that can replace or modify the embodiments described herein may exist at the time of filing this application.

[0050] It will be understood that when a component or layer is described as being "on," "connected to," or "attached to" another component or layer, it can be directly on, connected to, or attached to the other component or layer, or one or more intermediate components or layers may be present. When a component or layer is described as being "directly" on, directly connected to, or directly attached to another component or layer, no intermediate components or layers are present. For example, when a first component is described as being "attached" or "connected" to a second component, the first component can be directly attached to or connected to the second component, or the first component can be indirectly attached to or connected to the second component via one or more intermediate components.

[0051] In the accompanying drawings, the dimensions of various elements, layers, etc., may be enlarged for clarity of illustration. The same reference numerals indicate the same elements. As used herein, the term “and / or” includes any and all combinations of one or more associated listed items. Furthermore, the use of “may” in describing embodiments of this disclosure refers to “one or more embodiments of this disclosure.” Expressions such as “at least one of…” and “any one of…” preceding / following the list of elements modify the entire list of elements, but not individual elements in the list. When phrases such as “at least one of A, B, and C,” “at least one of A, B, or C,” “at least one selected from the group of A, B, and C,” or “at least one selected from A, B, and C” are used to specify a list of elements A, B, and C, the phrase may refer to any and all suitable combinations or subsets of A, B, and C, such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the term “use” may be considered synonymous with the term “utilize.” As used herein, the terms “roughly,” “approximately,” and similar terms are used as approximate terms rather than terms of degree and are intended to account for the inherent variations in measurements or calculations that would be apparent to a person skilled in the art.

[0052] It will be understood that while the terms first, second, third, etc., may be used to describe various elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or segment from another element, component, region, layer, or segment. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment.

[0053] For ease of description, this document uses spatial relative terms such as “below,” “under,” “down,” “above,” and “up” to describe the relationship between one element or feature and another element or feature as shown in the figures. It should be understood that spatial relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as “below” or “under” other elements or features can be oriented as “above” or “upon” other elements or features. Therefore, the term “below” can encompass both above and below orientations. The device can be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein should be interpreted accordingly.

[0054] The terminology used herein is for the purpose of describing embodiments of this disclosure and is not intended to be limiting of this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It should be further understood that when used in this specification, the terms “comprising” and / or “including” specify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0055] Furthermore, any numerical ranges disclosed and / or enumerated herein are intended to include all subranges with the same numerical precision contained within the enumerated ranges. For example, the range “1.0 to 10.0” is intended to include all subranges between the enumerated minimum value of 1.0 and the enumerated maximum value of 10.0 (and inclusive of both), i.e., a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as 2.4 to 7.6. Any maximum numerical limit enumerated herein is intended to include all lower numerical limits contained therein, and any minimum numerical limit enumerated in this specification is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to amend this specification, including the claims, to expressly enumerate any subranges contained within the scope expressly enumerated herein.

[0056] Referring to two compared elements, features, etc., as “identical” may mean that they are “substantially identical.” Therefore, the phrase “substantially identical” can include cases with deviations considered low in the art, such as 5% or less. Furthermore, when a parameter is said to be consistent in a given region, this may mean that it is consistent in terms of its mean.

[0057] Throughout this specification, unless otherwise stated, each element may be singular or plural.

[0058] Placing any element "above (or below)" or "above (or below)" another element may mean that the arbitrary element can be positioned to contact the upper (or lower) surface of the element, and other elements may also be positioned between the element and any element positioned on (or below) the element.

[0059] Furthermore, it will be understood that when a component is referred to as “connected,” “linked,” or “attached” to another component, the components can be directly “connected,” “linked,” or “attached” to each other, or another component can be “between” the components.

[0060] Throughout this specification, unless otherwise stated, when “A and / or B” is used, it means A, B, or A and B. In other words, “and / or” includes any or all combinations of the listed items. Unless otherwise indicated, when “C to D” is used, it means greater than or equal to C and less than or equal to D.

[0061] Batteries used in portable small electronic devices need to be detached from and replaced by the device as needed. A battery strap is attached to the battery to separate it from the electronic device. Therefore, it is necessary to ensure that the user can easily remove the battery from the electronic device by pulling the battery strap, while also strengthening the adhesion of the battery strap to the battery to ensure that the battery remains attached even if the device is dropped.

[0062] Figure 1 This is a schematic diagram illustrating a battery strip according to an embodiment of the present disclosure. Figure 2 This is an example illustrating an embodiment according to the present disclosure. Figure 1 The first direction, D1, shows the view of the battery band and the battery. Figure 3 This is a plan view illustrating a battery with a battery strap attached according to an embodiment of the present disclosure.

[0063] refer to Figures 1 to 3 The battery strip according to the embodiment may include a first member 100, a second member 200, and a third member 300. For example, the first member 100 may be placed on a first surface 11 of the battery 10. The first member 100 may be formed in a rectangular (e.g., square) shape. The first member 100 may be formed to correspond to the shape and size of the first surface 11. For example, the first member 100 may be formed to cover the entire area of ​​the first surface 11 of the battery 10 in terms of shape and size.

[0064] The first surface 11 of the battery 10 can be the lower surface of the battery 10 (e.g., Figure 7 The battery 10 may be placed on the first member 100 with its first surface 11 facing the first member 100.

[0065] The second member 200 may be formed to extend from the first member 100 in a first direction D1. The second member 200 may be adhered to at least a portion of a second surface 12 of the battery 10 opposite to the first surface 11. The second member 200 may include a pair of second members 200 extending from the first member 100 along the first direction D1.

[0066] The second member 200 may extend from a side portion of the first member 100 to cover a side surface of the battery 10. The first surface 11 of the battery 10 may be opposite to the second surface 12, and the side surface of the battery 10 may be a surface connecting the first surface 11 and the second surface 12. The second member 200 may be bent along the side surface of the battery 10 to partially adhere to the second surface 12 of the battery 10.

[0067] The shape of the second component 200 can be changed according to the desired design, and as an example, the shape can be as follows: Figure 1 The rectangular (e.g., square) form shown is not limited to this, but is selectively determined by those skilled in the art based on desired design.

[0068] The second component 200 may extend from the first component 100 in a first direction D1 to cover both side surfaces of the battery 10. The second component 200 may be adhered to the second surface 12 of the battery 10. An adhesive may be applied to at least one surface of the second component 200 to facilitate adhesion of the second component 200.

[0069] An adhesive may be applied to at least a portion of the second member 200 to adhere to the second surface 12 of the battery 10. The second member 200 may adhere to at least a portion of the second surface 12 of the battery 10. In this case, the second surface 12 of the battery 10 may be the upper surface of the battery 10, but is not limited thereto.

[0070] The second member 200 may extend from the side portion of the first member 100, and the second member 200 may adhere to at least a portion of the second surface 12 of the battery 10, thereby strengthening the bond between the battery strip and the battery 10.

[0071] Battery 10 can supply power to at least one component of an electronic device. For example, battery 10 may include a non-rechargeable primary battery, a rechargeable secondary battery, and / or a fuel cell, etc. Battery 10 can be positioned to be detached from the electronic device when battery 10 is replaced.

[0072] According to an embodiment, each of a pair of second members 200 may include a pull indicator line 201 adjacent to one end of the second member 200. The pair of second members 200 may overlap such that the pull indicator line 201 of one of the second members 200 may correspond to the pull indicator line 201 of the other to adhere to the second surface 12. For example, a second member 200 may include a pull indicator line 201 adjacent to one end (e.g., the end opposite to the end that connects the second member 200 to the first member 100) and formed in a second direction D2. The pair of second members 200 may overlap such that the pull indicator lines 201 may be aligned and / or intersect each other in the second direction D2 to adhere to the second surface 12.

[0073] A pair of second components 200 can overlap each other to adhere to the second surface 12, which allows the battery band to be strongly bonded to the battery 10. While one of the second components 200 can adhere to the second surface 12, the other of the second components 200 can be stacked and overlapped on top of the one of the second components 200 adhering to the second surface 12 to form an adhesive.

[0074] A pair of second components 200 can overlap each other to adhere to the second surface 12, such that a pull indicator line 201 of one of the second components can correspond to a pull indicator line 201 of the other of the second components 2. Therefore, the battery 10 can be securely fixed to the battery strap.

[0075] According to an embodiment, the third member 300 can be formed by extending from the first member 100 along a second direction D2 perpendicular to the first direction D1. The third member 300 can overlap at least a portion of the second surface 12. A pair of third members 300 can extend from the first member 100 in two directions along the second direction D2. The third member 300 can extend from both sides of the first member 100 in the second direction D2 to cover both side surfaces of the battery 10. The third member 300 can adhere to the second surface of the battery 10 opposite to the first surface 11 of the battery 10. An adhesive can be applied to at least one surface of the third member 300 to facilitate adhesion of the third member 300. The third member 300 can be bent along the side surfaces of the battery 10 to partially adhere to the second surface 12 of the battery 10.

[0076] The battery strip may include a first component 100 that is non-adhesive facing the first surface 11, and a second component 200 and a third component 300 that are adhesive. The adhesive may not be applied to the first component 100, thereby preventing noise generated due to the bonding between the first surface 11 of the battery 10 and the first component 100.

[0077] The film-type battery strip may include one surface with adhesive force and other surfaces without adhesive force. Therefore, the battery strip can be bonded together by the adhesive force in the second member 200 and the third member 300. However, the adhesive surfaces may be formed on both sides of the battery strip, and this disclosure is not limited thereto.

[0078] Therefore, the battery band according to the embodiments of this disclosure can prevent the battery 10 from detaching in the event of an electronic device being dropped, and minimize noise occurring in the battery band attachment area.

[0079] The third member 300 can have various shapes. The third member 300 may include two third members 300 extending from two side portions of the first battery 10, and the third members 300 may not overlap each other when adhered to the second surface 12 of the battery 10. For example, the third member 300 may include multiple rounded corners, with its width narrowing at the rounded corners along the side portion of the third member 300 away from the first member 100. However, the shape of the third member 300 is not limited to this.

[0080] Figure 4 This is a plan view illustrating a battery to which a battery strip is attached, according to an embodiment of the present disclosure. Figure 5 This is a view illustrating a second component of the battery strip according to an embodiment of the present disclosure, and Figure 6 This is a view illustrating another example of a pull indicator line for a second component according to an embodiment of the present disclosure.

[0081] refer to Figures 4 to 6 The pull indicator line 201 can be formed on the opposite sides of a pair of second members 200 in the second direction D2. For example, the pull indicator line 201 can be configured to break when tension is applied.

[0082] According to an embodiment, when the pull indicator lines 201, which break under tension, intersect each other, the second member 200 can adhere to the second surface 12, or the second member 200 can adhere to the second surface 12 even when the broken pull indicator lines 201 intersect each other. For example, the pull indicator lines 201 can be formed by a cutting line obtained along the second direction D2. Figure 5 (Example). For another example, the pull indicator line 201 can be formed by a dashed line extending along the second direction D2 ( Figure 6 (Example).

[0083] The second component 200 can be adhered to the second surface 12 of the battery, while intersecting with each other using pull indicator lines 201 that break upon application of tension. The force securing the second surface 12 with the second component 200 can be increased, and the bond between the battery band and the battery can be strengthened.

[0084] According to an embodiment, the length L of the pull indicator line 201 can be formed to be 30% or more of the width W of the second member 200 in the second direction D2, or the length L of the pull indicator line 201 can be formed to be 50% or less of the width W of the second member 200 in the second direction D2, or the length L of the pull indicator line 201 can be formed to be 30% to 50% of the width W of the second member 200 in the second direction D2. The length L of the pull indicator line 201 can be a length that allows a pair of second members 20 to intersect each other. When the length L of the pull indicator line 201 is formed to be 30% or less, the contact area between the intersecting second members 200 can be reduced, and when the length L of the pull indicator line 201 is formed to be 50% or more and tension is applied to the second member 220, the second member 202 can be torn.

[0085] Figure 7 This is a perspective view illustrating the state of the battery before it is arranged in the battery strip according to an embodiment of the present disclosure. Figure 8 This is a view illustrating the first surface of the battery placed on a battery strip according to an embodiment of the present disclosure. Figure 9 This is a view illustrating the application of tension to a second member according to an embodiment of the present disclosure. Figure 10 This is an illustrative view showing the application of tension to a second member according to an embodiment of the present disclosure to allow the indicator line to break under tension. Figure 11 This is a plan view illustrating the state of the battery band before the pull indicator lines intersect each other, according to an embodiment of the present disclosure.

[0086] refer to Figures 7 to 11 According to the embodiment, the battery strap can apply tension to the second member 200 when the battery 10 is placed on the first member 100, so as to allow the pull indicator lines formed on the respective end portions of the pair of second members 200 to overlap each other, so as to attach the second member 200 to the second surface 12, and the third member 300 can be attached to the third surface 12 to secure the battery 10.

[0087] The second component 200 and the third component 300 can be attached to the second surface 12 of the battery 10 by covering the side surface 13 of the battery after the first component 100 is disposed on the first surface of the battery 10.

[0088] The second component 200 can be folded toward the side surface 13 of the battery 10. For example, when a pair of second components 200 are folded while the battery 10 is placed on the first component 100, the pair of second components 200 can overlap each other. When the second component 200 is folded while the battery 10 is placed on the first component 100, the second component 200 can adhere to the second surface 12 by covering the side surface 13 of the battery 10. Adhesive may not be applied to the portion of the second component 200 that covers the side surface 13 of the battery 10.

[0089] The third component 300 can be folded toward the side surface 13 of the battery 10. For example, when both third components 300 are folded with the battery 10 placed on the first component 100, as... Figure 11 As shown, the third components 300 may not overlap each other. When the third component 300 is folded with the battery 10 placed on the first component 100, the third component 300 can adhere to the second surface 12 by covering the side surface 13 of the battery 10. Adhesive may not be applied to the portion of the third component 300 that covers the side surface 13 of the battery 10.

[0090] The second member 200 may extend from a side portion of the first member 100 to cover a side surface 13 of the battery 10. The second member 200 may be bent along the side surface 13 of the battery 10 to partially adhere to a second surface 12 of the battery 10. The second member 200 may extend from both side portions of the first member 100 to cover both side surfaces 13 of the battery 10. The second member 200 may adhere to a second surface 12 of the battery 10 opposite to the first surface of the battery 10.

[0091] When tension is applied (e.g. by pulling), Figure 9 When the second component 200 (represented by the dashed area in the diagram) is attached to the second surface 12, the corresponding second components 200 can overlap each other when the indicator lines 201 are pulled to correspond to each other. For example, as Figure 10 and Figure 11 As shown, after tension is applied to allow the pull indicator line 201 to break, the broken pull indicator lines 202 can overlap to intersect each other in the second direction D2.

[0092] A third member 300 may extend from a side portion of the first member 100 to cover a side surface 13 of the battery 10. The third member 300 may be bent along the side surface 13 of the battery 10 to partially adhere to a second surface 12 of the battery 10. A pair of third members 300 may extend from two corresponding side portions of the first member 100 to cover both side surfaces 13 of the battery 10. The third member 300 may adhere to a second surface 12 of the battery 10 opposite to the first surface of the battery 10.

[0093] For example, the side surface 13 of the battery 10 can be in close contact with the first surface and the second surface 12. The first surface 11 can be the lower surface of the battery 10, and the second surface 12 can be the upper surface of the battery 10 opposite to the first surface 11. When the battery 10 has a cubic shape, the side surface 13 of the battery 10 can include a third surface, a fourth surface, a fifth surface, and a sixth surface adjacent to the first surface and the second surface 12. The third surface can be opposite to the fifth surface, and the fourth surface can be opposite to the sixth surface. In this case, the second member 200 and the third member 300 can cover the third surface, the fourth surface, the fifth surface, and the sixth surface of the battery 10 to adhere to a portion of the second surface 12.

[0094] According to an embodiment, the protection circuit module (PCM) 20 can be mounted on one side surface 13 of the battery, and the third member 300 can be adhered to at least a portion of the second surface 12 of the battery 10, while covering the protection circuit module 20. The protection circuit module 20 can be connected to the battery 10 via a conductive nickel plate by soldering or brazing. The protection circuit module 20 can be connected to the cover of the battery 10 by spot welding or brazing.

[0095] The protection circuit module 20 may be electrically connected to the battery 10 and prevent overheating and explosion caused by overcharging, over-discharging, and / or overcurrent of the battery 10. The protection circuit module 20 may include safety elements made of passive elements such as resistors and capacitors and / or active elements such as field-effect transistors, or protection circuit elements in which integrated circuits are selectively formed.

[0096] The protection circuit module 20 can be placed on the side surface 13 of the battery 10. The protection circuit module 20 may include a flexible printed circuit board. The flexible printed circuit board may have a curved shape. The flexible printed circuit board may include a connector for connecting to an external device on one surface of an extension portion extending from one side. The protection circuit module 20 can be connected to an external device via the connector. The protection circuit module 20 can transfer electrical energy stored in the battery 10 to an external device, or receive control signals from an external device to control the operation of the battery 10.

[0097] When the protection circuit module 20 contacts one side surface 13 of the battery 10, the third member 300 can cover the side surface 13 of the battery 10 including the protection circuit module 20. Therefore, the protection circuit module 20 can be stably mounted on the side surface 13 of the battery 10.

[0098] Figure 12 This is a view illustrating a battery band according to an embodiment of the present disclosure. Figure 13 It is along Figure 12 The example shown is a cross-sectional view of the battery strip taken from line AA according to an embodiment of the present disclosure, and Figure 14 It is along Figure 12 The example shown is a cross-sectional view of the battery strip according to an embodiment of the present disclosure.

[0099] refer to Figures 12 to 14 The first component 100 may include a first substrate layer 100. The second component 200 may include a second substrate layer 210 extending from the first substrate layer 110 along a first direction D1 and a second adhesive layer 220 stacked on at least a portion of a surface of the second substrate layer 110. The third component 300 may include a third substrate layer 310 extending from the first substrate layer 110 along a second direction D2 and a third adhesive layer 320 stacked on at least a portion of a surface of the third substrate layer 310.

[0100] The first substrate layer 110, the second substrate layer 210, and the third substrate layer 310 can be formed without an adhesive layer. The second adhesive layer 220 can contact the second surface of the battery, allowing the second member 200 to contact the second surface, and the third adhesive layer 320 can contact the second surface to allow the third member 300 to adhere to the second surface.

[0101] The second adhesive layer 220 and the third adhesive layer 320 can be made from any of the commonly used adhesives without limitation. The second adhesive layer 220 can be formed by applying an acrylic adhesive to the second substrate layer 210. The third adhesive layer 320 can be formed by applying an acrylic adhesive to the third substrate layer 310. The acrylic adhesive can be selected from polymethyl methacrylate (PMMA), polyethyl methacrylate (PEMA), or polybutyl methacrylate (PBMA).

[0102] The second adhesive layer 220 and the third adhesive layer 320 can be formed to various thicknesses using various known methods. For example, the second adhesive layer 220 can be coated at 2% to 16% of the overall thickness of the second component 200. The second adhesive layer 220 can be coated at 4% to 14% of the overall thickness of the second component 200. For example, the second adhesive layer 220 can be coated at 6% to 12% of the overall thickness of the second component 200.

[0103] The second adhesive layer 220 may be formed on a portion of the surface of the second substrate layer 210. The second adhesive layer 200 may be formed only on the second substrate layer 210 at the portion where the second member 200 bends along the side surface of the battery to contact the second surface.

[0104] For example, the third adhesive layer 320 may be applied at a thickness of 2% to 16% of the overall thickness of the third component 300. Alternatively, the third adhesive layer 320 may be applied at a thickness of 4% to 14% of the overall thickness of the third component 300. Or, for example, the third adhesive layer 320 may be applied at a thickness of 6% to 12% of the overall thickness of the third component 300.

[0105] The third adhesive layer 320 may be formed on a portion of the surface of the third substrate layer 310. The third adhesive layer 320 may be formed only on the third substrate layer 310 at the portion where the third member 300 bends along the side surface of the battery to contact the second surface.

[0106] Figure 15 This is a view illustrating the non-adhesive area of ​​a battery strip according to an embodiment of the present disclosure.

[0107] refer to Figure 15 The second component 200 and the third component 300 may include non-adhesive regions without adhesive force. The non-adhesive region of the second component 200 may be formed at the end adjacent to the first component 100 and may include a second side surface region 230 covering the side surface of the battery in the first direction D1. The non-adhesive region of the third component 300 may be formed at the end adjacent to the first component 100 and may include a third side surface region 330 covering the side surface of the battery in the second direction D2. The second side surface region 230 and the third side surface region 330 may be formed as non-adhesive regions without adhesive force.

[0108] The second side surface 230 and the third side surface region 330 can be formed as non-adhesive regions without adhesive force to prevent noise from the battery band due to bonding. When the battery and battery band adhere to each other, noise may occur due to slight detachment, but since the second side surface 230 and the third side surface region 330 include non-adhesive regions without adhesive force, noise can be prevented.

[0109] For example, the second side surface region 230 of the battery strip corresponding to the side surface of the battery in the first direction D1 can be formed as a non-adhesive region to prevent noise from occurring between the battery strip and the side surface of the battery in the first direction D1. Similarly, the third side surface region 330 of the battery strip corresponding to the side surface of the battery in the second direction D2 can be formed as a non-adhesive region to prevent noise from occurring between the battery strip and the side surface of the battery.

[0110] Therefore, the noise that occurs between the battery strip and the battery can be minimized by including the second member 200 and the third member 300, which include a non-adhesive area that does not have adhesive force.

For example, as Figure 15 As shown, the third corner area 340 can be formed on two opposite corner areas of the third member 300 that are opposite to the side of the third member 300 that connects to the first member 100. However, the positions of the second corner area 240 and the third corner area 340 are not limited to this, but can be changed as needed.

[0114] According to an embodiment, the battery strap can be attached to the battery and combined with the battery to the electronic device. The battery can be detached from the electronic device by pulling on at least a portion of the battery strap attached to the battery.

[0115] A second corner zone 240 and a third corner zone 340 may be provided to allow the user to easily detach the battery strap from the battery. The second corner zone 240 and the third corner zone 340 can be pulled by the user's hand and are used to detach the battery from the electronic device. Therefore, the user can easily detach the battery strap from the battery.

[0116] For example, the area of ​​the second corner region 240 may be 5% to 20% of the total area of ​​the second component 200. In some embodiments, the area of ​​the third corner region 340 may be 5% to 20% of the total area of ​​the third component 300. However, this disclosure is not limited thereto, and the non-adhesive region may have various areas, as long as the battery is stably attached and secured. The areas of the second corner region 240 and the third corner region 340 are not limited, as long as the user can easily detach the battery band from the battery.
