Description

TECHNICAL FIELD

[0001] Aspects of embodiments of the present disclosure relate to a battery strap and a battery to which the battery strap is attached. BACKGROUND

[0002] Unlike primary batteries that are not designed to be (re)charged, secondary (or rechargeable) batteries are batteries designed to be discharged and recharged. Low-capacity secondary batteries are used for portable small electronic devices such as smartphones, feature phones, notebook computers, digital cameras, and camcorders, and large-capacity secondary batteries are widely used as power sources for driving electric motors in hybrid and electric vehicles and for storing electric power (e.g., home and / or utility-scale power storage). A secondary battery generally includes an electrode assembly composed of a positive electrode and a negative electrode, a case that accommodates the electrode assembly, and an electrode terminal connected to the electrode assembly.

[0003] When a battery is mounted on a small portable electronic device or the like, a battery strap attached to the battery can also be mounted on the electronic device. The battery strap should prevent the battery from moving within the electronic device and help prevent the battery from being disconnected even if the electronic device is dropped. However, the battery strap should also be easily separable from the electronic device.

[0004] The above information disclosed in this Background section is for enhancing the understanding of the background of the present disclosure, therefore it can include information that does not constitute the related (or prior) art. SUMMARY

[0044] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The terms or words used in the present specification and claims should not be interpreted as being limited to common or dictionary meanings, and should be interpreted as having a conception meeting the principles of the present disclosure based on the technical idea of the inventor who can appropriately define the terms or words to best describe his / her own invention.

[0045] The embodiments described in the present specification and the configurations shown in the accompanying drawings are only some of the embodiments of the present disclosure, and do not represent all technical spirits, aspects, and features of the present disclosure. Therefore, it should be understood that there can be various equivalents and modifications that can replace or modify the embodiments described herein at the time of filing the present application.

[0046] It will be understood that when an element or layer is referred to as being “on” or “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer, or one or more intervening elements or layers can also be present. In contrast, when an element or layer is referred to as being “directly on” or “directly connected to” or “directly coupled to” another element or layer, then there are no intervening elements or layers present. By way of example, when a first element is described as being “coupled” or “connected” to a second element, the first element can be directly coupled or connected to the second element or the first element can be indirectly coupled or connected to the second element via one or more intervening elements.

[0047] In the drawings, the size of various elements, layers, etc., can be exaggerated for clarity of illustration. Like reference numerals indicate like elements. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. Further, use of “can” in describing embodiments of the present disclosure relates to “one or more embodiments of the present disclosure.” Expressions such as “at least one of,” and “one or more of,” preceding a list of elements in the description are to be construed as applying to each element individually as well as to the whole list of elements in the entirety of the description. When a phrase such as “at least one of,” “at least one,” or “one or more of,” is used in conjunction with a list of two or more elements or instances, the phrase can be construed to refer to each singly one of those elements or instances, or it can be construed as a further recitation of at least one of the elements or instances from the whole list of elements or instances. As used herein, the term “use” can be considered synonymous with the term “utilize.” As used herein, the terms “substantially,” “about,” and similar terms are used as approximating terms and not as terms of degree, and are intended to account for the inherent variations in measurements or calculations that would be recognized by those of ordinary skill in the art.

[0048] It will be understood that, although the terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

[0049] For purposes of the description hereinafter, spatial or directional terms, such as, for example, "below," "lower," "upward," "upper," and the like, can be used with reference to the illustrated embodiment. Such terms are intended to facilitate the reader's understanding of the present disclosure, and are not intended to restrict the present disclosure to only those embodiments demonstrated in the figures. It will be further noted that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device described herein is turned over, then a relative term such as "below" or "under" can be used to describe a relationship that is reversed from that depicted in the figures. Accordingly, the term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0050] The terminology used herein is for the purpose of describing embodiments of the present disclosure, and is not intended to limit the present disclosure. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0051] Furthermore, any numerical ranges herein are intended to include all sub-ranges of the same numerical precision, i.e. 1.0 to 10.0 is intended to include 2.4 to 7.6, etc. Any maximum numerical limitation of any of the claims contained herein is intended to include all lower numerical limitations subsumed therein and any minimum numerical limitation of any of the claims contained herein is intended to include all higher numerical limitations subsumed therein. Accordingly, Applicant reserves the right to amend the claims to expressly recite any sub-range included therein.

[0052] Referring to two compared elements, features, etc., as "the same" can mean they are "substantially the same." Thus, the phrase "substantially the same" can include having a deviation that is considered low in the art, e.g., 5% or less. Also, when a parameter is said to be uniform in a given region, this can mean it is uniform in terms of average value.

[0053] Throughout the specification, unless otherwise indicated, each element can be singular or plural.

[0054] Arranging an arbitrary element "on (or under)" or "above (or below)" another element can mean that the arbitrary element can be disposed in contact with the upper (or lower) surface of the element, and another element can also be interposed between the element and the arbitrary element disposed on (or under) the element.

[0055] Furthermore, it will be understood that when a component is referred to as being "linked", "coupled", or "connected" to another component, the component can be directly "coupled", "linked", or "connected" to the other component, or a further component can be "interposed" between the components.

[0056] Throughout the specification, unless otherwise stated, when stating "A and / or B", 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 stating "C~D", it means C or more and D or less.

[0057] Figure 1 is a plan view of a battery belt 100 according to an embodiment of the disclosure. Figure 2 is a plan view of a battery 200 to which a part of the battery belt 100 is attached, according to an embodiment of the disclosure. The battery 200 can provide power to one or more components of an electronic device. For example, the battery 200 can include a primary cell that is not rechargeable, a secondary cell that is rechargeable, or a fuel cell, etc. In an embodiment, the battery 200 can be integrally disposed (or integrally arranged) within the electronic device. In another example, the battery 200 can be removably disposed (or removably mounted) to be attachable to and detachable from the electronic device in the case where the battery 200 needs to be replaced. The electronic device including the battery 200 can include a battery receptacle for receiving the battery 200. The battery belt 100 can include a first adhesive member 110 and a second adhesive member 120. The first adhesive member 110 can be attached to at least a part of a first surface of the battery 200. In such an embodiment, the first surface of the battery 200 can be, but is not limited to, a bottom surface of the battery 200. The battery 200 and the battery receptacle can be coupled to each other with the bottom surface of the battery 200 facing the battery receptacle. Reference will be made to Figure 4 The coupling relationship between the battery 200 and the battery receptacle will be described in more detail.

[0058] The second adhesive member 120 can extend from a side portion of the first adhesive member 110 and can be attached to at least a part of the battery 200. For example, the second adhesive member 120 can be attached to at least one of a second surface of the battery 200 opposite the first surface of the battery 200 and a side surface of the battery 200. The attachment of the second adhesive member 120 to at least a part of the battery 200 can further strengthen the bonding between the battery belt 100 and the battery 200.

[0059] The first adhesive member 110 can include a 1_1 sub-region 112. The 1_1 sub-region 112 can be attached to at least a portion of the first surface of the battery 200. The 1_1 sub-region 112 can be adhesive.

[0060] Referring to Figure 1 The 1_1 sub-region 112 can have the same (e.g., can have uniform) adhesive force per unit area. To make the 1_1 sub-region 112 adhesive, an adhesive can be applied to the 1_1 sub-region 112. The adhesive can be applied in the form of dots on the 1_1 sub-region 112 at regular intervals. As the size of the dots increases, the adhesive force per unit area of the sub-region can increase. Also, as the pitch between the dots becomes smaller, the adhesive force per unit area of the sub-region can increase. However, the adhesive force per unit area is not determined only by the size and pitch of the dots. For example, the adhesive force per unit area can also be determined by the material, thickness, etc. of the adhesive.

[0061] The first adhesive member 110 can further include a 1_2 sub-region 114. The 1_2 sub-region 114 can be located in a region in contact with the second adhesive member 120.

[0062] The 1_2 sub-region 114 can have an adhesive force lower than that of the 1_1 sub-region 112. Here, a non-adhesive region lacking adhesive force can be described as less adhesive than a region having adhesive force. For example, the 1_2 sub-region 114 can not have adhesive force, and thus have an adhesive force lower than that of the 1_1 sub-region 112. Accordingly, when the first adhesive member 110 is attached to the battery 200, the binding between the region of the battery 200 corresponding to the 1_2 sub-region 114 and the first adhesive member 110 can be relatively weak.

[0063] In an embodiment, the first adhesive member 110 can further include a 1_3 sub-region 116. The 1_3 sub-region 116 can be located at a corner of the first adhesive member 110. The 1_3 sub-region 116 can be a non-adhesive region. Accordingly, when the first adhesive member 110 is attached to the battery 200, the binding between the region of the battery 200 corresponding to the 1_3 sub-region 116 and the first adhesive member 110 can be relatively weak. The weak binding in this region can improve the joint structure of the battery 200 and the battery band 100.

[0064] The 1_3 sub-region 116 can have various shapes. For example, the 1_3 sub-region 116 can be "L"-shaped. In such an embodiment, the "L"-shaped corner of the 1_3 sub-region 116 can correspond to the corner of the first adhesive member 110. In another embodiment, the 1_3 sub-region 116 can have a rectangular shape. In another embodiment, the 1_3 sub-region 116 can have a triangular shape. For example, the 1_3 sub-region 116 can have a right-angled triangular shape. The 1_3 sub-region 116 can be positioned such that the right-angled portion of the right-angled triangular shape corresponds to the corner of the first adhesive member 110. Referring to Figure 1 The 1_3 sub-region 116 of the first adhesive member 110 is shown to be symmetrical about the X-axis and / or the Y-axis with respect to the center of the first adhesive member 110, but in other embodiments, the 1_3 sub-region 116 of the first adhesive member 110 can be asymmetrical. Also, in embodiments in which the 1_3 sub-region 116 exists as separate regions (e.g., spaced apart from each other), the respective regions can have shapes that are different from some regions or different from each region from each other. The shape of the 1_3 sub-region 116 is not limited to the above description, but the 1_3 sub-region 116 can have various shapes.

[0065] In an embodiment, the first adhesive member 110 can have a plurality of corners. Also, the first adhesive member 110 can include a plurality of 1_3 sub-regions 116. The 1_3 sub-regions 116 can be respectively located at the corners of the first adhesive member 110.

[0066] In an embodiment, the second adhesive member 120 can include a 2_1 sub-region 122. The 2_1 sub-region 122 can be located in a region in contact with the first adhesive member 110. Also, the 2_1 sub-region 122 can extend in a first direction. For example, the 2_1 sub-region 122 can have a length in the first direction and a width in a second direction.

[0067] In an embodiment, the first direction can be a horizontal or vertical direction of the battery strip 100. The second direction can be perpendicular to the first direction. For example, in an embodiment in which the battery strip 100 has a rectangular shape, the first direction can be a longitudinal direction of the battery strip 100, and the second direction can be a transverse direction of the battery strip 100. Referring to Figure 1 The first direction can be an X direction, and the second direction can be a Y direction.

[0068] In an embodiment, the length of the 2_1 sub-region 122 in the first direction can be shorter than the length of the first adhesive member 110.

[0069] In an embodiment, the 1_2 sub-region 114 can be located in a region in contact with the 2_1 sub-region 122. Accordingly, in an embodiment in which the battery strip 100 is separated from the battery 200, it can be advantageous to attach or separate the first adhesive member 110 after the 2_1 sub-region 122 is separated from the battery 200.

[0070] In an embodiment, a center of the 1_2 sub-region 114 in the first direction can coincide with a center of the 2_1 sub-region 122. In an embodiment, a width of the 1_2 sub-region 114 in the second direction can be shorter than a width of the 2_1 sub-region. In an embodiment, a length of the 1_2 sub-region 114 in the first direction can be shorter than a length of the 2_1 sub-region 122.

[0071] In an embodiment, the 2_1 sub-region 122 can have an adhesive force higher than that of the 1_1 sub-region 112. Also, the 2_1 sub-region 122 can have a larger adhesive force per unit area than other regions within the second adhesive member 120. Accordingly, the degree of bonding of the 2_1 sub-region 122 to at least one of the side surface and the second surface of the battery 200 can be stronger than the degree of bonding of the first adhesive member 110 to at least a portion of the first surface of the battery 200. Referring to Figure 1 , the black background region is a region to which an adhesive is continuously applied, and thus can have a higher adhesive force per unit area than the dot-shaped region.

[0072] In an embodiment, the second adhesive member 120 can further include a plurality of 2_2 sub-regions 126. The 2_2 sub-regions 126 can have the same or similar adhesive force as that of the 2_1 sub-region 122.

[0073] In an embodiment, the 2_2 sub-regions 126 can be attached to at least one of the second surface of the battery 200 or the side surface of the battery 200. For example, the side surface of the battery 200 can be connected to the first surface and the second surface of the battery 200. The first surface of the battery 200 can correspond to a bottom surface of the battery 200, and the second surface of the battery 200 can correspond to a top surface of the battery 200. In an embodiment in which the battery 200 is a hexahedron, the side surface of the battery 200 can include a third surface, a fourth surface, a fifth surface, and a sixth surface connected to (e.g., extending from) the first surface and the second surface. The third surface can be opposite the fifth surface, and the fourth surface can be opposite the sixth surface. One of the 2_2 sub-regions 126 can be attached to at least one of the second surface and the third surface. Another of the 2_2 sub-regions 126 can be attached to at least one of the fifth surface opposite the third surface and the second surface. Another of the 2_2 sub-regions 126 can be attached to at least one of the fourth surface, the sixth surface, and the top surface.

[0074] In one embodiment, the second adhesive member 120 may further include a pull portion 124, which is a portion of the second adhesive member 120 extending in a second direction. At least a portion of the pull portion 124 may be adhesive. The adhesive portion of the pull portion 124 may be attached to at least one of the second surface and side surface of the battery 200.

[0075] In one embodiment, the pull portion 124 may include one or more second-second sub-regions 126. For example, the second-second sub-regions 126 may be provided on a peripheral portion of the pull portion 124. The second-second sub-regions 126 may be provided on one or both sides of the pull portion 124 in a first direction and on one side in a second direction. Because at least one second-second sub-region 126 is attached to at least one of the second surface and side surface of the battery 200, the pull portion 124 may also be attached to the battery 200. A portion of the remaining region of the pull portion 124, excluding the second-second sub-regions 126, may also be adhesive. The adhesive strength of this portion of the remaining region of the pull portion 124, excluding the second-second sub-regions 126, may be the same as or lower than the adhesive strength of the first-first sub-region 112.

[0076] In one embodiment, the pull portion 124 may include a second and third sub-region 128 provided on the portion of the pull portion 124 where the adhesive force has been removed. For example, the second and third sub-region 128 may be located at a corner of the pull portion 124. The second and third sub-region 128 where the adhesive force has been removed can be used to separate the pull portion 124 from the battery 200.

[0077] In one embodiment, the second adhesive member 120 may include a tear line. For example, the tear line may be provided around the second sub-region 122. Because the adhesive force of the second sub-region 122 is greater than that of the first sub-region 112, the battery band 100 may be bonded to the second sub-region 122 more firmly than it may be bonded to the first sub-region 112. In embodiments where the battery band 100 is pulled using the pull portion 124, the battery band 100 may be divided along the tear line into a portion including the first sub-region 112 and a portion including the second sub-region 122.

[0078] In one embodiment, the second adhesive member 120 may include a folded portion 129 extending in a first direction. The folded portion 129 may allow the second adhesive member 120 to fold relative to an edge of the battery 200. Thus, the second adhesive member 120, including the pull portion 124 and the second sub-region 126, may be attached to at least one of the side surface and the second surface of the battery 200.

[0079] Referring to Figure 2 In an embodiment in which the battery strap 100 is to be attached to the battery 200, the battery 200 can be positioned on the battery strap 100 such that the first surface of the battery 200 faces the first adhesive member 110. The area of the first adhesive member 110 can be greater than the area of the first surface of the battery 200. Thereafter, the second adhesive member 120 can be folded toward the side surface of the battery 200 using the folding portion (or folding portions) 129. The adhesive regions included in the second adhesive member 120 (e.g., the 2_1 sub-region 122, the 2_2 sub-region 126, and at least a portion of the pulling portion 124) can be attached to at least one of the side surface and the second surface of the battery 200. Referring to Figure 3 The structure in which the battery strap 100 is coupled to the battery 200 is described in more detail.

[0080] The 1_3 sub-region 116 can reduce noise generated due to the combination of the battery 200 with the first adhesive member 110 and / or the attachment of the battery 200 to the first adhesive member 110 and the separation of the battery 200 from the first adhesive member 110. The connection between the battery 200 and the first adhesive member 110 can be improved. Furthermore, the weakening of the combination between the battery 200 and the first adhesive member 110 due to the 1_3 sub-region 116 can be compensated for by the second adhesive member 120.

[0081] Figure 3 is a perspective view of a battery 310 to which a battery strap 320 according to an embodiment of the disclosure is attached. As described above with reference to Figure 1 and Figure 2 The battery strap 320 can be attached to the battery 310 such that the first surface of the battery 310 faces the first adhesive member of the battery strap 320. Thereafter, the second adhesive member 322 can be folded with respect to the side surface of the battery 310 by using the folding portion 324, and can be attached to at least one of the side surface and the second surface of the battery 310 by the adhesive regions included in the second adhesive member 322. From Figure 3 Some configurations of the second adhesive member 322 are omitted from the illustration of

[0082] Referring to Figure 3 , the battery strap 320 is shown as being attached to the surface of the battery 310, but the disclosure is not limited thereto. For example, the battery 310 can have an insulating member, an insulating tape, a protective film, a mark indicating information about the battery 310, etc. attached / coupled to at least a portion of the surface thereof. The battery strap 320 can be attached to the battery 310 in a state in which the other configurations are attached / coupled to the surface of the battery 310.

[0083] The battery 310 to which the battery strap 320 is attached can be coupled to the battery receptacle. The battery 310 can be coupled to the battery receptacle such that a first surface of the battery 310 to which the first adhesive member is attached faces the battery receptacle. Referring to Figure 4 The structure in which the battery 310 to which the battery strap 320 is attached is coupled to the battery receptacle is described in more detail.

[0084] Figure 4 is a side view of a battery 410 coupled to a battery receptacle 430 according to an embodiment of the disclosure. Referring to Figure 4 The battery receptacle 430 can have a space for receiving (or housing) the battery 410 to which the battery strap 420 is attached. For example, the battery receptacle 430 can have a space for receiving the battery 410 configured to supply power to the electronic device.

[0085] The first adhesive member 422 of the battery strap 420 can be attached to a first surface of the battery 410. The folding portion 424 can allow the second adhesive member 426 to be folded with respect to a side surface of the battery 410. Accordingly, the second adhesive member 426 can be attached to at least a portion of a side surface or a second surface of the battery 410. Similarly, the pulling portion 428 can be attached to at least a portion of the side surface or the second surface of the battery 410. Referring to Figure 4 The pulling portion 428 is illustrated as being attached to the second surface of the battery 410, but the disclosure is not limited thereto.

[0086] The battery strap 420 can include a first surface on which the first adhesive member 422 is provided and a second surface attached to a second surface of the battery 410 opposite the first surface of the battery 410. The battery strap 420 can be attached to the battery 410 such that the first surface thereof faces the battery 410. The battery 410 can be received in the battery receptacle 430 such that the second surface of the battery strap 420 faces a bottom of the battery receptacle 430.

[0087] In addition, a bonding strap can be provided between the second surface of the battery strap 420 and the bottom of the battery receptacle 430. The bonding strap can have adhesive force on opposite surfaces, thereby facilitating bonding of the battery 410 to which the battery strap 420 is attached and the battery receptacle 430.

[0088] The battery 410 coupled to the battery receptacle 430 can be decoupled from the battery receptacle 430 by using the battery strap 420. For example, the pulling portion 428 of the battery strap 420 can be separated from the battery 410. For example, the 2_3 sub-area included in the pulling portion 428 can not be attached to the battery 410. The pulling portion 428 can be separated from the battery 410 by using the 2_3 sub-area. The pulling portion 428 can be pulled in a third direction or a direction between the second direction and the third direction. The third direction can be perpendicular to the first direction and the second direction. In this case, the battery 410 can be decoupled from the battery receptacle 430 by using the battery strap 420.Figure 4 In the comparative battery band, the third direction can refer to a Z direction. In addition, the third direction can be a direction in which an opening area in which the battery receptacle 430 is provided is located. In response to pulling the pulling portion 428, the battery band 420 attached to the battery 410 can be lifted up. The battery 410 coupled to the battery band 420 can also be lifted up, thereby decoupling the battery 410 from the battery receptacle 430. The battery 410 to which the battery band 420 is attached can be separated from the battery receptacle 430 by using the pulling portion 428.

[0089] Figure 5 is a plan view of a comparative battery band according to the present disclosure. Figure 6 is a graph illustrating a test result of a separation force of the comparative battery band. Referring to Figure 5 , the comparative battery band can be the same as the battery band 100 shown in Figure 1 In the comparative battery band, the third direction can refer to a Z direction. In addition, the third direction can be a direction in which an opening area in which the battery receptacle 430 is provided is located. In response to pulling the pulling portion 428, the battery band 420 attached to the battery 410 can be lifted up. The battery 410 coupled to the battery band 420 can also be lifted up, thereby decoupling the battery 410 from the battery receptacle 430. The battery 410 to which the battery band 420 is attached can be separated from the battery receptacle 430 by using the pulling portion 428. Figure 1 In the comparative battery band, the third direction can refer to a Z direction. In addition, the third direction can be a direction in which an opening area in which the battery receptacle 430 is provided is located. In response to pulling the pulling portion 428, the battery band 420 attached to the battery 410 can be lifted up. The battery 410 coupled to the battery band 420 can also be lifted up, thereby decoupling the battery 410 from the battery receptacle 430. The battery 410 to which the battery band 420 is attached can be separated from the battery receptacle 430 by using the pulling portion 428. Figure 1 In the comparative battery band, the third direction can refer to a Z direction. In addition, the third direction can be a direction in which an opening area in which the battery receptacle 430 is provided is located. In response to pulling the pulling portion 428, the battery band 420 attached to the battery 410 can be lifted up. The battery 410 coupled to the battery band 420 can also be lifted up, thereby decoupling the battery 410 from the battery receptacle 430. The battery 410 to which the battery band 420 is attached can be separated from the battery receptacle 430 by using the pulling portion 428. Figure 5 In the comparative battery band, the third direction can refer to a Z direction. In addition, the third direction can be a direction in which an opening area in which the battery receptacle 430 is provided is located. In response to pulling the pulling portion 428, the battery band 420 attached to the battery 410 can be lifted up. The battery 410 coupled to the battery band 420 can also be lifted up, thereby decoupling the battery 410 from the battery receptacle 430. The battery 410 to which the battery band 420 is attached can be separated from the battery receptacle 430 by using the pulling portion 428. Figure 6 In the comparative battery band, the third direction can refer to a Z direction. In addition, the third direction can be a direction in which an opening area in which the battery receptacle 430 is provided is located. In response to pulling the pulling portion 428, the battery band 420 attached to the battery 410 can be lifted up. The battery 410 coupled to the battery band 420 can also be lifted up, thereby decoupling the battery 410 from the battery receptacle 430. The battery 410 to which the battery band 420 is attached can be separated from the battery receptacle 430 by using the pulling portion 428.

[0090] The battery band 510 can be separated from the battery 522 to which the first adhesive member 512 is attached by pulling the pulling portion 514 from the battery 522. In response to pulling the pulling portion 514 of the battery band 510, the battery band 510 and the battery 522 can be separated from each other. In the process of separating the battery 522, the size of the attachment area of the first adhesive member 512 and the battery 522 can sequentially decrease in the second direction A.

[0091] The separation force can refer to a force for pulling the pulling portion 514 to separate the first adhesive member 512 from the battery 522. During a process of pulling the pulling portion 514, a value of the separation force generated as the size of the attachment area of the first adhesive member 512 and the battery 522 decreases in the second direction A can be measured. The separation force test can be performed by measuring the separation force between the first adhesive member 512 and the battery 522. Referring to Figure 6 , the separation force test graph 600 illustrates a value of the separation force as a function of a travel distance of the pulling portion 514.

[0092] In the separation force test graph 600, it can be seen that a strong force is required at an initial stage of pulling the pulling portion 514. When the first adhesive member 512 is separated from the battery 522, a part of the first adhesive member 512 can be separated from the battery 522, and the remaining part of the first adhesive member 512 can (or can remain) attached to the battery 522. At this time, a boundary can be formed between the separated part of the first adhesive member 512 and the attached remaining part of the first adhesive member 512. When the boundary on the first adhesive member 512 in contact with the pulling portion 514 is set as a first boundary and the boundary of the first adhesive member 512 is set as a second boundary, the distance between the first boundary and the second boundary can be measured. The separation force test graph 600 can represent the value of the separation force as a function of the distance between the first boundary and the second boundary. In this case, due to the properties of the battery tape 510, the battery tape 510 can be stretched in response to the pulling of the pulling portion 514. Accordingly, the distance between the first boundary and the second boundary in the separation force test graph 600 can be different from the length of the battery tape 510 that is not stretched.

[0093] In the separation force test graph 600, the reference distance 610 can be the distance between the first boundary and the second boundary at which the value of the separation force is the greatest. The reference distance 610 can correspond to the area of the first adhesive member 512 in contact with the 2_1 sub-area. Figure 6 It can be seen that, in the separation force test graph 600, the value of the separation force is the greatest at the reference distance 610. As the bonded area of the first adhesive member 512 and the battery 522 begins to decrease, the value of the separation force can decrease. In this regard, the reference distance 610 can correspond to the area of the first adhesive member 512 in contact with the 2_1 sub-area. The reference area 524 can correspond to the area of the first adhesive member 512 in contact with the 2_1 sub-area, and decreasing the adhesive force in the reference area 524 of the first adhesive member 512 can decrease the maximum value of the separation force. For example, due to the reference area 524, the 1_2 sub-area 114 can be formed in the area of the battery tape 100 corresponding to the reference area 524 as shown in FIG. 11, thereby decreasing the maximum value of the separation force. Figure 1 It can be seen that, in the separation force test graph 600, the value of the separation force is the greatest at the reference distance 610. As the bonded area of the first adhesive member 512 and the battery 522 begins to decrease, the value of the separation force can decrease. In this regard, the reference distance 610 can correspond to the area of the first adhesive member 512 in contact with the 2_1 sub-area. The reference area 524 can correspond to the area of the first adhesive member 512 in contact with the 2_1 sub-area, and decreasing the adhesive force in the reference area 524 of the first adhesive member 512 can decrease the maximum value of the separation force. For example, due to the reference area 524, the 1_2 sub-area 114 can be formed in the area of the battery tape 100 corresponding to the reference area 524 as shown in FIG. 11, thereby decreasing the maximum value of the separation force.

[0094] Figure 7 is a plan view of a battery tape according to a first example 710 of the disclosure. Figure 8 is a plan view of a battery tape according to a second example 720 of the disclosure. Figure 9 is a plan view of a battery tape according to a third example 730 of the disclosure. Figure 10 is a graph illustrating the separation force of the battery tape according to the first example 710 to the third example 730. Each of the first example 710 to the third example 730 can be the same as the battery tape 100 as shown in FIG. 11, except for the size of the 1_2 sub-area and the 2_1 sub-area. Figure 1 is a graph illustrating the separation force of the battery tape according to the first example 710 to the third example 730. Each of the first example 710 to the third example 730 can be the same as the battery tape 100 as shown in FIG. 11, except for the size of the 1_2 sub-area and the 2_1 sub-area. Figure 1The dimensions of the first and second sub-regions 114 of the battery strip 100 shown are different. In another example, one of the first example 710 to the third example 730 can be... Figure 1 The battery pack shown is the same as 100.

[0095] In one embodiment, the center of the first_2 sub-region of each of the first examples 710 to the third examples 730 may coincide with the center of the second_1 sub-region in a first direction. Furthermore, the center of the first_2 sub-region may coincide with the center of the first_1 sub-region in the first direction.

[0096] refer to Figures 7 to 9 In each of the first examples 710 to the third example 730, up to 35 adhesive points may be provided on the first adhesive member in the first direction. For example, in each of the first examples 710 to the third example 730, 35 adhesive points may be formed in the first direction in a region of the first adhesive member where neither the first_2 sub-region nor the first_3 sub-region exists. In another example, in each of the first examples 710 to the third example 730, fewer than 35 adhesive points may be formed in the first direction in a region of the first adhesive member where either the first_2 sub-region or the first_3 sub-region exists.

[0097] In the first example 710, the first_2 sub-region 714 can be formed by removing three adhesive points from the area of ​​the first adhesive member 712 that contacts the second_1 sub-region. In the second example 720, the first_2 sub-region 724 can be formed by removing 13 adhesive points from the area of ​​the first adhesive member 722 that contacts the second_1 sub-region. In the third example 730, the first_2 sub-region 734 can be formed by removing 23 adhesive points from the area of ​​the first adhesive member 732 that contacts the second_1 sub-region.

[0098] References can be executed for each of the first examples 710 to the third examples 730. Figure 5 and Figure 6 The separation force test is described. The results of the separation force test are shown in Table 1 below.

[0099] Table 1

[0100]

[0101]

[0102] For each of the comparative examples, first example 710, second example 720, and third example 730, three separation force tests were performed. Subsequently, for each of the three separation force tests, the average, maximum, and minimum values ​​were calculated. The measurements in Table 1 indicate the values ​​of the separation force measured at the reference length, and may be the maximum value of the separation force. The unit of separation force is kgf.

[0103] refer to Figure 10 Comparative examples can be used (e.g., Figure 5 The test results of the battery strips shown (comparative example 510), first example 710, second example 720, and third example 730) are used to determine the value of the separation force based on the number of adhesive points removed. Figure 10 The graph shown is the average of three separation force tests using the first example 710, the second example 720, and the third example 730. A separation force of approximately 14.7 kgf can be measured in the comparative example where the number of adhesive points removed is 0; approximately 12.9 kgf can be measured in the first example 710 where the number of adhesive points removed is 3; approximately 11.9 kgf can be measured in the second example 720 where the number of adhesive points removed is 13; and approximately 10.9 kgf can be measured in the third example 730 where the number of adhesive points removed is 23. Furthermore, in... Figure 10 The graph shown illustrates a line connecting the data from the various comparative examples, first example 710, second example 720, and third example 730. Therefore, it can be seen that as the number of adhesive points removed increases (e.g., as the number of adhesive points decreases), the size of the first-second sub-region without adhesive force increases, and as the size of the first-second sub-region increases, the value of the separation force decreases.

[0104] A lower separation force can weaken the bond between the first adhesive member and the battery, and the first adhesive member and the battery can be easily separated from each other. Therefore, the value of the separation force is expected to be at least a reference (or predetermined) amount. In one embodiment, the length of the first_2 sub-region may be shorter than the length of the second_1 sub-region in the first direction. For example, the number of adhesive points removed may be equal to or less than a reference (or predetermined) number, and the length of the first_2 sub-region may be shorter than the length of the second_1 sub-region. With this configuration, the separation force may be greater than or equal to the reference (or predetermined) value.

[0105] Using the above configuration, the separation force between the first adhesive member and the battery can be increased. Furthermore, adjusting the length of the first and second sub-regions can ensure that the separation force between the first adhesive member and the battery has appropriate strength.

[0106] Figure 11is a flowchart describing a battery strap attachment method according to an embodiment of the disclosure. In an embodiment, the method S1100 of applying a battery strap can include attaching a first adhesive member of the battery strap to a first surface of a battery (S1110).

The first adhesive member can include a 1_1 sub-region and a 1_2 sub-region having an adhesive force lower than the 1_1 sub-region, and the 1_2 sub-region can be located in an area in contact with a second adhesive member. The adhesive force of the 1_2 sub-region can be removed.

[0107] In an embodiment, a length of the 1_2 sub-region can be shorter than a length of the 2_1 sub-region in a first direction. Also, a center of the 1_2 sub-region can coincide with a center of the 2_1 sub-region along the first direction. Also, the 2_1 sub-region can have a width in a second direction perpendicular to the first direction, and a width of the 1_2 sub-region can be smaller than the width of the 2_1 sub-region. A separation force between the first adhesive member and the battery can be reduced in proportion to a size of the 1_2 sub-region.

[0108] In an embodiment, the first adhesive member can include a 1_3 sub-region located at a corner of the first adhesive member and having an adhesive force removed. The 1_3 sub-region can be located at the corner of the first adhesive member, respectively. The 1_3 sub-region can be "L" shaped.

[0109] In an embodiment, a second adhesive member included in the battery strap and extending from a side portion of the first adhesive member can be attached to at least one of a second surface of the battery opposite the first surface of the battery and a side surface of the battery (S1120).

[0110] In an embodiment, the second adhesive member includes a 2_1 sub-region which can be located in an area in contact with the first adhesive member and extend in a first direction. Also, a length of the 2_1 sub-region can be shorter than a length of the first adhesive member in the first direction. An adhesive force of the 2_1 sub-region can be greater than an adhesive force of the 1_1 sub-region.

[0111] In an embodiment, the second adhesive member can further include a 2_2 sub-region, and the 2_2 sub-region can be attached to at least one of a second surface of the battery opposite the first surface and a side surface of the battery.

[0112] In an embodiment, the second adhesive member can include a pulling portion, for example, at least a portion of the second adhesive member extending in a second direction. At least a portion of the pulling portion can be adhesive, and the pulling portion can be attached to at least one of a second surface of the battery opposite the first surface and a side surface of the battery. Also, the pulling portion can include a 2_3 sub-region on a portion thereof having an adhesive force removed.

[0113] In an embodiment, the second adhesive member can include a folded portion extending in the first direction, and the folded portion can allow the pulling portion to be folded with respect to the side surface of the battery. The first direction can be perpendicular to the second direction.

[0114] In an embodiment, the battery can be coupled to the battery receptacle such that the first surface of the battery faces the battery receptacle (S1130). In response to pulling of the pulling portion, the battery can be decoupled from the battery receptacle.
