Description

TECHNICAL FIELD

[0001] Aspects of embodiments of the present disclosure relate to a battery attachment tape and a battery to which the battery attachment tape is attached. Specifically, aspects of embodiments of the present disclosure relate to a battery attachment tape having a noise improvement structure and a battery to which the battery attachment tape 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 small portable electronic devices such as smartphones, feature phones, notebook computers, digital cameras, camcorders, etc., and high-capacity secondary batteries are widely used as power sources for driving electric motors in hybrid and electric vehicles and as power sources 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 houses the electrode assembly, and an electrode terminal connected to the electrode assembly.

[0003] Specifically, in the case of mounting a battery on a small portable electronic device or the like, a battery attachment tape can be attached and mounted thereon. The battery attachment tape is needed to prevent the battery from moving within the electronic device and can help prevent the battery from separating from the electronic device even in the case of the electronic device falling. In addition, in the case of the battery attachment tape being attached to the battery, it is desirable to minimize the noise generated at the attachment site.

[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

[0013] In an embodiment, the adhesive portion can include a first adhesive area and a second adhesive area, and an adhesive strength of the second adhesive area can be less than an adhesive strength of the first adhesive area.

[0014] In an embodiment, the second adhesive area can be formed in a portion of a periphery of the non-adhesive area.

[0015] In an embodiment, the adhesive portion can include a first adhesive area and a second adhesive area, the non-adhesive area can have a right triangle shape, a right angle portion of the non-adhesive area can face a corner of the adhesive portion, the second adhesive area is formed in an area around a hypotenuse portion of the non-adhesive area, and an adhesive strength of the second adhesive area can be less than an adhesive strength of the first adhesive area.

[0016] In an embodiment, a portion of the battery attachment tape can further include a pulling portion extending in one direction of the battery attachment tape on one side of the battery attachment tape.

[0017] In an embodiment, the adhesive portion can include a first adhesive area and a third adhesive area, the third adhesive area can extend in a first direction, the first direction is an extension direction of the pulling portion, and an adhesive strength of the third adhesive area can be greater than an adhesive strength of the first adhesive area.

[0018] In an embodiment, the third adhesive area can include a plurality of third adhesive areas arranged in parallel to each other.

[0019] In an embodiment, the third adhesive region can be formed at a middle of the adhesive portion with respect to a second direction perpendicular to the first direction.

[0020] In an embodiment, the third adhesive region can be formed at one end or opposite ends of the adhesive portion with respect to a second direction perpendicular to the first direction.

[0021] In an embodiment, the third adhesive region can be formed at opposite ends of the adhesive portion with respect to a second direction perpendicular to the first direction, and the third adhesive region formed at a first end of the adhesive portion can be wider than the third adhesive region formed at a second end of the adhesive portion.

[0042] Hereinafter, embodiments of the present disclosure will be described in greater detail 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 generally used meanings or dictionary definitions, and should be interpreted as meanings and concepts consistent with the technical idea of the present disclosure based on the principle that the inventor can appropriately define the terms to best describe his / her own invention. Accordingly, the description and drawings merely preferentially illustrate some embodiments of the present disclosure.

[0043] The embodiments described in the present specification and the configurations shown in the accompanying drawings are only some 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, at the time of filing the present application, there can be various equivalents and modifications that can replace or modify the embodiments described herein.

[0044] It will be understood that when an element or layer is referred to as being "on" another element or layer, "connected to" or "coupled to" another element or layer, it can be directly on the other element or layer, directly connected to or coupled to the other element or layer, or one or more intervening elements or layers can also be present. When an element or layer is referred to as being "directly on" another element or layer, "directly connected to" or "directly coupled to" another element or layer, there are no intervening elements or layers present. For example, when a first element is described as being "coupled" or "connected" to a second element, the first element can be directly coupled or directly connected to the second element, or the first element can be indirectly coupled or indirectly connected to the second element via one or more intervening elements.

[0045] In the figures, the dimensions of various elements, layers, etc., may be exaggerated for clarity. The same reference numerals denote the same or identical elements. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Furthermore, when describing embodiments of this disclosure, the use of "may" refers to "one or more embodiments of this disclosure." Expressions such as "at least one of..." and "any one of..." modify the entire column of elements, rather than individual elements within that column. 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 represent a column of elements A, B, and C, the phrase may refer to any suitable combination (or subset) of A, B, and C, and all suitable combinations (or subsets), 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" and its variations may be considered synonymous with the term "utilize" and its variations, respectively. As used herein, the terms "basically," "about," and similar terms are used as approximations rather than terms of degree, and are intended to explain the inherent variations in measurements or calculations that will be recognized by one of ordinary skill in the art.

[0046] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the teachings of the exemplary embodiments, the first element, first component, first region, first layer, or first portion discussed below may be designated as a second element, second component, second region, second layer, or second portion.

[0047] For ease of description, spatially relative terms, such as "below", "lower", "under", "above", "upper" and the like, can be used herein for describing an element's or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially 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 a device is inverted or rotated by 90 degrees, an element described as "below" or "under" another element or feature would then be oriented "above" or "over" the other element or feature. Thus, the term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0048] The terminology used herein is for the purpose of describing embodiments of the present disclosure and is not intended to be limiting of 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", "comprising", "includes" and / or "including", when used herein, 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.

[0049] Further, any numerical ranges herein are intended to include all sub-ranges encompassed therein. For example, a range from 1.0 to 10.0 should be construed as including any number falling between 1.0 and 10.0, not just including the number 5.0. Any numerical range is intended to include every number falling within the range, including the end points of the range. At least, applicants reserve the right to amend this specification to expressly recite any such sub-ranges as claimed. All such ranges are intended to be inherently described in this specification, such that amending to expressly recite any such sub-ranges would comply with the requirements of 35 U.S.C. § 112, first paragraph, as that provision exists on December 18, 2014, following Afocal Industries, LLC v. ITC, 750 F.3d 1568 (Fed. Cir. 2014) (en banc).

[0050] 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 cases where there is a deviation considered low in the art (e.g., 5% or less). Additionally, when a parameter is said to be uniform in a given region, it can mean it is uniform in terms of average.

[0051] Throughout the specification, unless otherwise stated, each element can be singular or plural.

[0052] Arranging an arbitrary element "above (or below)" or "on (under)" another element can mean that the arbitrary element can be disposed in contact with the upper (or lower) surface of the other element, or can mean that yet another element can be interposed between the other element and the arbitrary element disposed on (or under) the other element.

[0053] In addition, it will be understood that when a component is referred to as being "linked", "coupled", or "connected" to another component, the element can be directly "coupled", "linked", or "connected" to each other, or another component can be "interposed" between the components.

[0054] Throughout the specification, unless otherwise stated, when "A and / or B" is stated, it means A, B, or A and B. That is, "and / or" includes any combination or all combinations of the listed items. When "C to D" is stated, unless otherwise stated, it means C or greater and D or less.

[0055] Throughout the specification, the same or similar components are given the same or similar reference numerals, and repeated descriptions will be omitted.

[0056] Figure 1 A plan view of a battery attachment tape 100 according to an embodiment of the disclosure is illustrated. Figure 2 A plan view of a battery cell 200 to which a portion of a battery attachment tape 100 according to an embodiment of the disclosure is attached is illustrated. The battery attachment tape 100 can include an adhesive portion 110 positioned on a first surface of the battery attachment tape 100. The adhesive portion 110 can include an adhesive region 112 having an adhesive strength for attachment to at least a portion of one surface of the battery cell 200, and a non-adhesive region 114 having no adhesive strength. The non-adhesive region 114 can be formed at at least one corner of the adhesive portion 110.

[0057] In some embodiments, the adhesive portion 110 can include a plurality of non-adhesive regions 114_1 to 114_4. In addition, the adhesive portion 110 can include a plurality of corners. For example, referring to Figure 1 In the case where the adhesive portion 110 has a rectangular shape, the adhesive portion 110 can include four corners. The non-adhesive regions 114_1 to 114_4 can be formed in at least some of the corners of the adhesive portion 110.

[0058] In some embodiments, the first non-adhesion region 114_1 can be formed at a first corner. Also, the second non-adhesion region 114_2 can be formed at a second corner. The first corner and the second corner can be positioned at one side of the adhesive portion 110. The one side of the adhesive portion 110 can be associated with one end of the fixing tape 400 to be attached to the second surface of the battery attachment tape 100. The second surface of the battery attachment tape 100 can face the first surface of the battery attachment tape 100. Referring to Figure 5 The detailed description of the relationship between the fixing tape 400 and the adhesive portion 110.

[0059] In some embodiments, the adhesive portion 110 can include a first non-adhesion region 114_1, a second non-adhesion region 114_2, a third non-adhesion region 114_3, and a fourth non-adhesion region 114_4. Also, the adhesive portion 110 can include a first corner, a second corner, a third corner, and a fourth corner. The first non-adhesion region 114_1 to the fourth non-adhesion region 114_4 can be formed at the first corner to the fourth corner, respectively. That is, in the case where the adhesive portion 110 has a rectangular shape having four corners, the non-adhesion regions can be formed at the four corners, respectively.

[0060] In some embodiments, the non-adhesion region 114 can have a triangular shape. Referring to Figure 1 In the case where the non-adhesion region 114 has a right triangle shape, the right angle portion of the non-adhesion region 114 can be positioned toward the corner of the adhesive portion 110. However, the shape of the non-adhesion region 114 is not limited thereto, and the non-adhesion region 114 can have various shapes.

[0061] In some embodiments, the area of the non-adhesion region 114 can be 10% to 15% of the area of the adhesive portion 110. For example, the non-adhesion region 114 can occupy about 13% of the total area of the adhesive portion 110. However, the present disclosure is not limited thereto, and the non-adhesion region 114 can have various areas as long as the adhesive portion 110 can be attached to the battery cell 200.

[0062] In some embodiments, the adhesive region 112 can include a first adhesive region 113, a second adhesive region 116, and a third adhesive region 118. The second adhesive region 116 can be smaller than the first adhesive region 113. The third adhesive region 118 can be smaller than the first adhesive region 113.

[0063] In some embodiments, the second adhesive region 116 can be formed on a portion of the periphery of the non-adhesion region 114. As a non-limiting example, referring to Figure 1The second adhesive region 116 can include a 2_1 adhesive region 116_1, a 2_2 adhesive region 116_2, a 2_3 adhesive region 116_3, and a 2_4 adhesive region 116_4. The 2_1 adhesive region 116_1 can be formed around the first non-adhesive region 114_1. Similarly, the 2_2 adhesive region 116_2 can be formed around the second non-adhesive region 114_2. The 2_3 adhesive region 116_3 can be formed around the third non-adhesive region 114_3. The 2_4 adhesive region 116_4 can be formed around the fourth non-adhesive region 114_4.

[0064] In some embodiments, in a case where the non-adhesive region 114 has a right triangle shape and a right angle portion of the non-adhesive region 114 faces a corner of the adhesive portion 110, the second adhesive region 116 can be formed in a hypotenuse portion of the non-adhesive region 114. Referring to FIG. 1B, Figure 1 A right angle portion of the first non-adhesive region 114_1 can face a corner of the adhesive portion 110, and the 2_1 adhesive region 116_1 can be formed in a hypotenuse portion of the first non-adhesive region 114_1. Similarly, a right angle portion of the second non-adhesive region 114_2 can face a corner of the adhesive portion 110, and the 2_2 adhesive region 116_2 can be formed in a hypotenuse portion of the second non-adhesive region 114_2. A right angle portion of the third non-adhesive region 114_3 can face a corner of the adhesive portion 110, and the 2_3 adhesive region 116_3 can be formed in a hypotenuse portion of the third non-adhesive region 114_3. A right angle portion of the fourth non-adhesive region 114_4 can face a corner of the adhesive portion 110, and the 2_4 second adhesive region 116_4 can be formed in a hypotenuse portion of the fourth non-adhesive region 114_4.

[0065] In some embodiments, the battery attachment tape 100 can include a pulling portion 120 on one side of the battery attachment tape 100, in which a portion of the battery attachment tape 100 extends in a direction of one side of the battery attachment tape 100. Referring to FIG. 1B, Figure 1 The pulling portion 120 can be a portion of the battery attachment tape 100 extending in a first direction (for example, an X-axis direction). At least a portion of the pulling portion 120 can have an adhesive strength. At least a portion of the pulling portion 120 having the adhesive strength can be attached to at least a portion of a side surface of a cell of the battery cell 200.

[0066] In some embodiments, the pulling portion 120 can include a region in which the adhesive strength has been removed from a portion of the pulling portion 120. For example, the region in which the adhesive strength has been removed can be positioned at a corner of the pulling portion 120. The pulling portion 120 attached to the battery cell 200 can be separated from the battery cell 200 by using the region in which the adhesive strength has been removed.

[0067] In some embodiments, the adhesive portion 110 can include a third adhesive region 118 extending in a first direction, which is an extension direction of the pulling portion 120. The third adhesive region 118 can have a greater adhesive strength than the first adhesive region 113. Referring to Figure 1 , the third adhesive region 118 can include a 3_1 adhesive region 118_1, a 3_2 adhesive region 118_2, and a 3_3 adhesive region 118_3.

[0068] In some embodiments, the third adhesive region 118 can include a plurality of third adhesive regions arranged in parallel to each other. As the number of the third adhesive regions arranged in parallel increases, the third adhesive region 118 can expand. As the third adhesive region 118 expands, the adhesive strength of the third adhesive region 118 can increase. Referring to Figure 1 , the 3_3 adhesive region 118_3 can have a greater adhesive strength than the 3_2 adhesive region 118_2 or the 3_1 adhesive region 118_1. In other embodiments, as one third adhesive region 118 expands, the adhesive strength of the third adhesive region 118 can increase.

[0069] In some embodiments, the 3_1 adhesive region 118_1 can be formed in the middle of the adhesive portion 110 with respect to a second direction (e.g., a Y-axis direction) perpendicular to the first direction. In other embodiments, the 3_2 adhesive region 118_2 can be positioned at one end of the adhesive portion 110 with respect to the second direction. In other embodiments, the 3_3 adhesive region 118_3 can be positioned at the other end of the adhesive portion 110 with respect to the second direction. Referring to Figure 1 , the 3_1 adhesive region 118_1 to the 3_3 adhesive region 118_3 can exist together in one adhesive portion 110.

[0070] In some embodiments, the battery attachment tape 100 can include a wing portion 130 extending in the second direction on one side thereof. At this time, the one side of the battery attachment tape 100 can be different from the side of the battery attachment tape 100 on which the pulling portion 120 is formed. At least a portion of the wing portion 130 can have an adhesive strength. The at least a portion of the wing portion 130 having the adhesive strength can be attached to at least a portion of a side surface of a battery of the battery cell 200.

[0071] For example, the wing portion 130 can include a first wing portion 130_1 and a second wing portion 130_2. Referring to Figure 1 , the first wing portion 130_1 and the second wing portion 130_2 can be formed on one side of the battery attachment tape 100. However, the present disclosure is not limited thereto, and the first wing portion 130_1 and the second wing portion 130_2 can be positioned on different sides of the battery attachment tape 100.

[0072] In other embodiments, the 3_2 adhesive region 118_2 can be positioned at one end of the adhesive portion 110 with respect to the second direction. Also, the 3_3 adhesive region 118_3 can be positioned at the other end of the adhesive portion 110 with respect to the second direction. In this case, the wing portion 130 in which a portion of the battery attachment tape 100 extends can be positioned in a region in contact with the one end of the adhesive portion 110 in which the 3_2 adhesive region 118_2 is positioned. In a case where the one end of the battery attachment tape 100 in which the 3_3 adhesive region 118_3 is positioned is an upper end and the one end of the battery attachment tape 100 in which the 3_2 adhesive region 118_2 is positioned is a lower end, the wing portion 130 can be positioned at the lower end of the battery attachment tape 100.

[0073] In some embodiments, the adhesive strength of the wing portion 130 can be greater than the adhesive strength of the first adhesive region 113. For example, the adhesive strength of the wing portion 130 can be equal to or similar to the adhesive strength of the third adhesive region 118. In a case where the battery attachment tape 100 is attached to the battery cell 200, the engagement between the lower end of the battery attachment tape 100 in which the wing portion 130 is positioned and the battery cell 200 can be stronger than the engagement between the upper end of the battery attachment tape 100 and the battery cell 200. To compensate for this, the number of 3_3 adhesive regions 118_3 can be greater than the number of 3_2 adhesive regions 118_2. Accordingly, the engagement between the upper end of the battery attachment tape 100 and the battery cell 200 can be equal to or similar to the engagement between the lower end of the battery attachment tape 100 and the battery cell 200.

[0074] In some embodiments, the battery attachment tape 100 can include a strong adhesive portion 140. The strong adhesive portion 140 can be formed on one side of the battery attachment tape 100. The strong adhesive portion 140 can be attached to at least a portion of the side surface of the battery cell 200. The adhesive strength of the strong adhesive portion 140 can be equal to or greater than the adhesive strength of the third adhesive region 118. The strong adhesive portion 140 can help the battery attachment tape 100 to be relatively firmly engaged to a surface other than the first surface of the battery cell 200. Here, the first surface of the battery cell 200 can refer to one surface engaged to the first surface of the battery attachment tape 100.

[0075] As described above, the non-adhesive region 114 has no adhesive strength, and the adhesive strength of the second adhesive region 116 is weaker than the adhesive strength of the first adhesive region 113. Accordingly, the engagement between the adhesive portion 110 and the battery cell 200 can be relatively weak. In this case, because the adhesive portion 110 includes the third adhesive region 118 having a relatively high adhesive strength, the engagement between the adhesive portion 110 and the battery cell 200 can be supplemented.

[0076] Referring toFigure 2 In a case where the battery attachment tape 100 is attached to the battery cell 200, a lower surface of the battery cell 200 can be positioned on the first surface of the battery attachment tape 100. In this case, an area of the adhesive portion 110 can be greater than an area of the first surface of the battery cell 200. Thereafter, the pull portion 120, the wing portion 130, and the strong adhesive portion 140 can be attached to at least a portion of a side surface of the battery cell 200. In addition, each of the pull portion 120, the wing portion 130, and the strong adhesive portion 140 can also be attached to a second surface of the battery cell 200. Here, the second surface of the battery cell 200 can face the first surface of the battery cell 200. Referring to Figure 3 The structure in which the battery attachment tape 100 is joined to the battery cell 200 is described in detail.

[0077] The non-adhesive region 114 can reduce noise generated due to attachment between the battery cell 200 and the adhesive portion 110, and can improve the joining between the battery cell 200 and the adhesive portion 110. In addition, by including the second adhesive region 116 around the non-adhesive region 114, noise generated due to attachment between the battery cell 200 and the adhesive portion 110 can be further reduced. In addition, in response to weakening of the joining between the battery cell 200 and the adhesive portion 110 due to the non-adhesive region 114, the third adhesive region 118 can supplement the joining between the adhesive portion 110 and the battery cell 200. That is, the adhesive portion 110 and the battery cell 200 can be firmly joined through the third adhesive region.

[0078] Figure 3 A perspective view showing a battery cell 310 to which a battery attachment tape 320 is attached according to an embodiment of the disclosure is shown. As described above with reference to Figure 1 and Figure 2 The first surface of the battery cell 310 can be attached to face the first surface of the battery attachment tape 320 on which the adhesive portion is formed. Thereafter, the pull portion 322, the wing portion (not shown), and the strong adhesive portion 324 can be attached to at least a portion of a side surface of the battery cell 310. In addition, each of the pull portion 322, the wing portion, and the strong adhesive portion 324 can also be attached to a second surface of the battery cell 310. Here, the second surface of the battery cell 310 can face the first surface of the battery cell 310. In Figure 3 In the above-described embodiment, some components of the battery attachment tape 320 are not shown, and the disclosure is not limited thereto.

[0079] The battery cell 310 can be coupled to the battery fixing portion in a state in which the battery attachment tape 320 is attached thereto. The first surface of the battery cell 310 to which the adhesive portion is attached can be coupled to face the battery fixing portion. In this case, in order to fix the battery fixing portion, a fixing tape can be attached to the second surface of the battery attachment tape 320, and the fixing tape can be coupled to the battery fixing portion. In this case, the second surface of the battery attachment tape 320 can face the battery fixing portion. The second surface of the battery attachment tape 320 can face the first surface of the battery attachment tape 320. Referring to Figures 4 to 8 The detailed description of the coupling relationship between the fixing tape, the battery attachment tape 320, and the battery fixing portion.

[0080] Figure 4 A plan view showing a fixing tape 400 according to an embodiment of the disclosure is shown. The fixing tape 400 can be attached to the second surface of the battery attachment tape (for example, the battery attachment tape 100) of the battery 300. Here, the second surface of the battery attachment tape can face the first surface of the battery attachment tape on which the adhesive portion is formed. Figure 1

[0081] The fixing tape 400 can include a body portion 410 and a leg portion 420. The body portion 410 and the leg portion 420 can be connected to each other, and the leg portion 420 can extend in a form branched from the body portion 410. The leg portion 420 can include a first leg portion 420_1 and a second leg portion 420_2.

[0082] The first leg portion 420_1 and the second leg portion 420_2 can be positioned on one side of the body portion 410. The first leg portion 420_1 and the second leg portion 420_2 can not be connected to each other. In some embodiments, the width of the first leg portion 420_1 and the width of the second leg portion 420_2 can be different from each other.

[0083] The fixing tape 400 can have an adhesive strength on both the first surface and the second surface. Here, the first surface and the second surface of the fixing tape 400 can face each other. The first surface of the fixing tape 400 can be attached to the second surface of the battery attachment tape, and the second surface of the fixing tape 400 can be attached to the battery fixing portion. Accordingly, the battery cell (for example, the battery cell 200 of the battery 300) can be fixed to the battery fixing portion. Figure 2

[0084] Figure 5 ​​A plan view of the battery cell 510 to which the battery attachment tape 520 and the fixing tape 530 are attached is shown. The first surface of the battery attachment tape 520 can be attached to the first surface of the battery cell 510. Specifically, the adhesive portion of the battery attachment tape 520 can be attached to the first surface of the battery cell 510. Thereafter, the first surface of the fixing tape 530 can be attached to the second surface of the battery attachment tape 520. Figure 5 is a view of the second surface of the battery cell 510 to which the battery attachment tape 520 and the fixing tape 530 can be attached. Figure 5 The adhesive portion is shown for ease of explanation. However, the adhesive portion can not appear when the battery cell 510 to which the battery attachment tape 520 and the fixing tape 530 are attached is actually viewed from the second surface.

[0085] In some embodiments, the battery cell can include a first corner region 512_1, a second corner region 512_2, a third corner region 512_3, and a fourth corner region 512_4 on the second surface thereof. Each of the corner regions 512_1 to 512_4 can correspond to a portion of the adhesive portion of the battery attachment tape 520. The first corner region 512_1 can correspond to a first non-adhesive region (e.g., the first non-adhesive region 114_1 of Figure 1 and a 2_1 adhesive region (e.g., the 2_1 adhesive region 116_1 of Figure 1 ). Similarly, the second corner region 512_2 can correspond to a second non-adhesive region (e.g., the second non-adhesive region 114_2 of Figure 1 and a 2_2 adhesive region (e.g., the 2_2 adhesive region 116_2 of Figure 1 ). The third corner region 512_3 can correspond to a third non-adhesive region (e.g., the third non-adhesive region 114_3 of Figure 1 and a 2_3 adhesive region (e.g., the 2_3 adhesive region 116_3 of Figure 1 ). The fourth corner region 512_4 can correspond to a fourth non-adhesive region (e.g., the fourth non-adhesive region 114_4 of Figure 1 and a 2_4 adhesive region (e.g., the 2_4 adhesive region 116_4 of Figure 1 ).

[0086] In some embodiments, each of the corner regions 512_1 to 512_4 can correspond to the fixing tape 530. The first corner region 512_1 can correspond to one end of the first leg portion 534_1. The second corner region 512_2 can correspond to one end of the second leg portion 534_2. The third corner region 512_3 and the fourth corner region 512_4 can correspond to corners of the body portion 532, respectively.

[0087] When the battery cell 510, the battery attachment tape 520, and the fixing tape 530 are attached to each other, respectively, noise can occur when a portion of the battery attachment tape 520 is attached to or detached from the battery cell 510 or the fixing tape 530. For example, noise can occur between a portion of the adhesive portion of the battery attachment tape 520 corresponding to the first corner region 512_1 and one end of the first leg portion 534_1 of the fixing tape 530. Similarly, noise can occur between a portion of the adhesive portion of the battery attachment tape 520 corresponding to the second corner region 512_2 and one end of the second leg portion 534_2 of the fixing tape 530. For example, noise can occur between a portion of the adhesive portion of the battery attachment tape 520 corresponding to the third corner region 512_3 and an edge of the main body portion 532 of the fixing tape 530. Similarly, noise can occur between a portion of the adhesive portion of the battery attachment tape 520 corresponding to the fourth corner region 512_4 and an edge of the main body portion 532 of the fixing tape 530.

[0088] In some embodiments, due to the first non-adhesive region and / or the 2_1 adhesive region corresponding to the first corner region 512_1, less noise can occur in the first corner region 512_1. Similarly, due to the second non-adhesive region and / or the 2_2 adhesive region corresponding to the second corner region 512_2, less noise can occur in the second corner region 512_2. In some embodiments, due to the third non-adhesive region and / or the 2_3 adhesive region corresponding to the third corner region 512_3, less noise can occur in the third corner region 512_3. Similarly, due to the fourth non-adhesive region and / or the 2_4 adhesive region corresponding to the fourth corner region 512_4, less noise can occur in the fourth corner region 512_4. In other words, since the non-adhesive regions do not have adhesive strength and the second adhesive regions have relatively weak adhesive strength, noise occurring between the battery attachment tape 520 and the fixing tape 530 can be minimized.

[0089] Figure 6 An exploded perspective view of a battery cell 610, a battery attachment tape 620, a fixing tape 630, and a battery fixing portion 640 according to an embodiment of the disclosure is illustrated. Figure 7 A state in which the battery cell 610, the battery attachment tape 620, the fixing tape 630, and the battery fixing portion 640 are joined according to an embodiment of the disclosure is illustrated.

[0090] In some embodiments, the battery cell 610, the battery attachment tape 620, the fixing tape 630, and the battery fixing portion 640 can be joined to each other in the order. Specifically, the first surface of the battery cell 610 and the first surface of the battery attachment tape 620 can be joined to each other. In this case, an adhesive portion can be formed on the first surface of the battery attachment tape 620. The first surface of the fixing tape 630 can be joined to the second surface of the battery attachment tape 620. The first surface and the second surface of the fixing tape 630 can have an adhesive strength. The second surface of the fixing tape 630 can be joined to the battery fixing portion 640. That is, the battery cell 610 can be joined to the battery fixing portion 640 such that the first surface of the battery cell 610 faces the battery fixing portion 640.

[0091] In some embodiments, the battery fixing portion 640 can be included in an electronic device. For example, the electronic device can include the battery fixing portion 640 in order to accommodate the battery cell 610. In the electronic device, the battery fixing portion 640 can be associated with a space for fixing the battery cell 610 by using the fixing tape 630.

[0092] Referring to Figure 7 , in a case where the first surface of the battery cell 610 is referred to as a lower surface, the battery attachment tape 620 can be joined to the bottom of the battery cell 610. The fixing tape 630 can be joined to the bottom of the battery attachment tape 620. The battery fixing portion 640 can be joined to the bottom of the fixing tape 630. In Figure 7 , the battery cell 610, the battery attachment tape 620, the fixing tape 630, and the battery fixing portion 640 are illustrated to have the same width, but are not limited thereto, and can have different widths.

[0093] Figure 8 A state in which a battery cell 810, a battery attachment tape, a fixing tape, and a battery fixing portion 820 are joined according to an embodiment of the disclosure is illustrated. A first surface of the battery attachment tape can be attached to a first surface of the battery cell 810, a first surface of the fixing tape can be attached to a second surface of the battery attachment tape, and the battery fixing portion 820 can be attached to a second surface of the fixing tape. In Figure 8 , a second surface of the battery cell 810 described with reference to Figure 6 and Figure 7 may be illustrated to face downward. In addition, in Figure 8 , the battery attachment tape and the fixing tape can not be illustrated when viewed from above the second surface of the battery fixing portion 820. In Figure 8 , the battery fixing portion 820 is depicted to be transparent to ensure the display of the battery attachment tape and the fixing tape.

[0094] Referring to Figure 8The battery fixing portion 820 can have an A-axis. For example, the A-axis can be parallel to the second direction of the battery attachment tape 100. Figure 1 However, the present disclosure is not limited thereto, and the A-axis can be parallel to the first direction of the battery attachment tape 100. Figure 1 In addition, the A-axis can also pass through the center of the battery attachment tape 100.

[0095] The battery fixing portion 820 can be twisted counterclockwise and clockwise with respect to the A-axis. Referring to Figure 8 The battery fixing portion 820 can be twisted in the direction B with respect to the A-axis. As the battery fixing portion 820 is twisted, noise can occur between the battery cell 810, the battery attachment tape, the battery fixing portion, and the battery fixing portion 820. For example, noise can mainly occur in the first corner region (e.g., the first corner region 512_1 of the battery attachment tape 100) and the second corner region (e.g., the second corner region 512_2 of the battery attachment tape 100). Figure 5 For example, noise can mainly occur in the third corner region (e.g., the third corner region 512_3 of the battery attachment tape 100) and the fourth corner region (e.g., the fourth corner region 512_4 of the battery attachment tape 100). Figure 5 Figure 5 Figure 5

[0096] In some embodiments, the adhesive strength of the portion of the adhesive portion of the battery attachment tape corresponding to the first corner region to the fourth corner region can be removed, or can be relatively weak, compared to the adhesive strength of the other portions. For example, the first non-adhesive region of the adhesive portion corresponding to the first corner region can not have adhesive strength. The adhesive strength of the 2_1 non-adhesive region of the adhesive portion corresponding to the first corner region can be relatively weak compared to the adhesive strength of the first adhesive region. Accordingly, in the case where the battery fixing portion 820 to which the battery cell 810 is attached is twisted with respect to the A-axis, noise occurring between the battery cell 810 and the battery attachment tape, between the battery attachment tape and the fixing tape, and / or between the fixing tape and the battery fixing portion can be eliminated or reduced.

The non-adhesive region can include a first non-adhesive region formed at the first corner, a second non-adhesive region formed at the second corner, a third non-adhesive region formed at the third corner, and a fourth non-adhesive region formed at the fourth corner. For example, the non-adhesive region can have a triangular shape.

The adhesive strength of the third adhesive region can be greater than the adhesive strength of the first adhesive region. For example, the third adhesive region can be formed at the middle of the adhesive portion with respect to a second direction perpendicular to the first direction. For example, the third adhesive region can be formed at one end or opposite ends of the adhesive portion with respect to the second direction perpendicular to the first direction. For example, the third adhesive region can be formed at opposite ends of the adhesive portion with respect to the second direction perpendicular to the first direction, and the third adhesive region formed at one end of the adhesive portion can be wider than the third adhesive region formed at the other end of the adhesive portion.

[0105] In some embodiments, a portion of the battery attachment tape can further include a wing portion extending in the second direction in a region adjacent to the other end of the adhesive portion. Here, the wing portion can be attached to at least a portion of the side surface of the battery cell.
