Description

Technical Field

[0001] Various embodiments disclosed herein relate to a battery structure and an electronic device including the battery structure. Background Art

[0002] As the demand for portable electronic devices increases, the demand for batteries that power the electronic devices is also increasing. To meet this growing demand, technologies in the battery field are also steadily developing.

[0003] Meanwhile, as the demand for miniaturization, thinning, and / or weight reduction of electronic devices increases, the installation space for electronic components is decreasing. For example, the installation space for a battery within an electronic device is decreasing. Summary of the Invention

[0004] Technical Problem

[0005] As electronic devices become miniaturized and thinner, the space occupied by the battery structure within the electronic device is designed to be limited. Specifically, an electronic device worn on a part of a user's body (such as a wearable electronic device) may have size limitations in consideration of user comfort. As a result, the space occupied by the battery structure within the wearable electronic device can be reduced. At the same time, when implementing a battery structure in a limited space, the size of a battery cell is restricted. In this case, the capacity of the battery structure may be limited. As a result, the time for a consumer to use the electronic device may be reduced.

[0006] According to an embodiment of the present disclosure, the space occupied by a protection circuit module within the space allocated to the battery structure in an electronic device can be reduced. In this case, the size of the battery cell can be increased by the reduced space to ensure the capacity of the battery cell.

[0007] Solution to the Problem

[0008] According to an embodiment of the present disclosure, an electronic device may include: a battery cell; a battery pouch that seals the battery cell, the battery pouch including a receiving portion and a first sealing portion, the battery cell being disposed in the receiving portion, the first sealing portion being bent to face the battery cell and including at least one groove; electrode terminals including a first electrode tab connected to a positive electrode plate of the battery cell and led out to the first sealing portion and a second electrode tab connected to a negative electrode plate of the battery cell and led out to the first sealing portion; and a protection circuit module including at least one electronic component and disposed on the first sealing portion such that the electronic component is located in the groove of the first sealing portion, the protection circuit module being connected to the electrode terminals.

[0009] According to an embodiment of the present disclosure, a battery structure may include: a battery cell; a battery pouch that seals the battery cell, the battery pouch including a receiving portion and a first sealing portion, the battery cell being disposed in the receiving portion, the first sealing portion being bent to face the receiving portion and including at least one groove; electrode terminals including a first electrode tab connected to a positive electrode plate of the battery cell and led out to the first sealing portion and a second electrode tab connected to a negative electrode plate of the battery cell and led out to the first sealing portion; and a protection circuit module including at least one electronic component and disposed on the first sealing portion such that the electronic component is located in the groove of the first sealing portion, the protection circuit module being connected to the electrode terminals.

[0010] Advantages of the Invention

[0011] According to an embodiment of the present disclosure, the space between components constituting the battery structure can be reduced. In this case, the size of the battery cell can be increased by the reduced space between the components to ensure the capacity of the battery cell. For example, in the battery structure, the space occupied by the protection circuit module (PCM) of the battery structure can be reduced, and the size of the battery cell can be increased by the reduced space.

The communication module 190 may include one or more communication processors capable of operating independently of the processor 120 (e.g., an application processor (AP)), and support direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). Each of these communication modules may communicate with an external electronic device via a first network 198 (e.g., a short-range communication network, such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network, such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN))). These various types of communication modules may be implemented as a single component (e.g., a single chip), or these various types of communication modules may be implemented as multiple separate components (e.g., multiple chips). The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an international mobile subscriber identity (IMSI)) stored in the user identification module 196.

The negative electrode plate can function as an anode during the discharge of the battery cell 310, thereby releasing lithium ions into the electrolyte contained in the battery cell 310, and can function as a cathode during charging, thereby storing reduced lithium atoms. The negative electrode plate can include a negative electrode current collector, which includes a thin metal plate, such as copper and / or a negative electrode active material. The negative electrode active material can include, for example, artificial and / or natural graphite that stores lithium by intercalation, various silicon-based compounds (such as silicon oxides, silicon nitrides, and / or silicon carbides), and lithium metal or its various alloys and metal compounds that store metallic lithium. The separator can be a member that allows lithium ions to pass through while preventing electrical contact between the positive electrode and the negative electrode. In an embodiment, the separator can include a polymeric material, such as polyethylene or polypropylene, which has micropores of a size that allows lithium ions to pass through. The smallest unit of a battery including a negative electrode, a positive electrode, and a separator can be referred to as a battery cell 310 or an electrode assembly.

[0058] According to an embodiment, the battery structure 300 can include various types of batteries. In an embodiment, the battery structure 300 can include a jelly roll type battery. The jelly roll can include a structure in which a positive electrode plate and a negative electrode plate are stacked and wound together. The positive electrode plate and the negative electrode plate can be wound together with a separator interposed therebetween. According to another embodiment, the battery structure 300 can include a stacked type electrode assembly in which a positive electrode plate, a negative electrode plate, and / or a separator are stacked. The positive electrode plate can refer to the electrode from which electrons flow out. Since a chemical reaction in which electrons are lost occurs at the positive electrode plate, the positive electrode plate can be understood as the electrode where an oxidation reaction occurs. The positive electrode active material for positive electrode activation can be coated on at least one surface of the positive electrode plate. The negative electrode plate can refer to the electrode into which electrons flow. Since a chemical reaction in which electrons are gained occurs on the negative electrode plate, the negative electrode plate can be understood as the electrode where a reduction reaction occurs. The negative electrode active material for negative electrode activation can be coated on at least one surface of the negative electrode plate. In this way, an electric current can be generated through the redox reaction between the positive electrode plate and the negative electrode plate with a separator interposed therebetween.

[0059] According to an embodiment, a separator disposed between a positive electrode plate and a negative electrode plate may serve as an electrolyte in the battery cell 310.

Inorganic particles may be bonded to one or both surfaces of the separator.

[0060] According to an embodiment, the positive electrode plate of the battery cell 310 may be connected to a first electrode tab 361. For example, the first electrode tab 361 may be in contact with the positive electrode plate. In some embodiments, the first electrode tab 361 may be integrated with the positive electrode plate. The negative electrode plate of the battery cell 310 may be connected to a second electrode tab 362, which will be described later. For example, the second electrode tab 362 may be in contact with the negative electrode plate. In some embodiments, the second electrode tab 362 may be integrated with the negative electrode plate.

[0061] According to an embodiment, as Figure 3 shown, the battery pouch 320 may seal the battery cell 310. In an embodiment, the battery pouch 320 may accommodate the positive electrode plate, the negative electrode plate, and the separator, and may seal the positive electrode plate, the negative electrode plate, and the separator from the external environment. For example, the battery pouch 320 may include a metal (e.g., aluminum or stainless steel), a polymer material, and / or a composite material or laminate thereof. In an embodiment, an organic electrolyte (not shown) may be injected and sealed inside the battery pouch 320. For example, the organic electrolyte may include a lithium salt and an organic solvent.

[0062] In an embodiment, referring to Figure 3, the battery bag 320 may include a receiving portion 321 and sealing portions 330, 340, and 350. The battery cell 310 is placed in the receiving portion 321, and the sealing portions 330, 340, and 350 are the remaining areas left after enclosing the battery cell 310. The receiving portion 321 may be the internal space of the battery bag 320, and the battery cell 310 is disposed in this internal space. The sealing portions 330, 340, and 350 may be the areas where the remaining areas after receiving the battery cell 310 are joined. For example, when the sealing portions 330, 340, and 350 are joined by heat sealing or an adhesive member, the battery bag 320 may seal the battery cell 310. In an embodiment, the sealing portions 330, 340, and 350 may be formed on the left side, right side, and lower side of the battery cell 310. For example, the battery bag 320 may include a first sealing portion 330 located on the lower side of the battery cell 310 (e.g., based on Figure 3 the -y direction), a second sealing portion 340 located on the right side of the battery cell 310 (e.g., based on Figure 3 the +x direction, the first direction), and a third sealing portion 350 located on the left side of the battery cell 310 (e.g., based on Figure 3 the -x direction, the second direction). In some embodiments, the sealing portions 330, 340, and 350 may be formed on the left side (e.g., based on Figure 3 the -x direction), right side (e.g., based on Figure 3 the +x direction), upper side (e.g., based on Figure 3 the +y direction), and lower side (e.g., based on Figure 3 the -y direction) of the battery cell 310. Additionally, depending on the size and shape of the battery cell 310, the sealing portions 330, 340, and 350 may be formed at various positions relative to the battery cell 310.

[0063] According to an embodiment, as Figure 4a , Figure 4b and Figure 4c shown, the battery structure 300 may include a first electrode tab 361 connected to the positive electrode plate of the battery cell 310 and a second electrode tab 362 connected to the negative electrode plate. The first electrode tab 361 and the second electrode tab 362 may be led out to at least one of the sealing portions 330, 340, and 350. For example, the first electrode tab 361 may be connected to the positive electrode plate of the battery cell 310 and led out to the first sealing portion 330, and the second electrode tab 362 may be connected to the negative electrode plate of the battery cell 310 and led out to the first sealing portion 330. Hereinafter, it is assumed that the first electrode tab 361 and the second electrode tab 362 are led out to the first sealing portion 330.

[0064] According to an embodiment, the battery structure 300 may include a protection circuit module 400 (e.g., Figure 2 the battery protection circuit (protection circuit module (PCM)) 240 in ). The protection circuit module 400 may perform one or more of various functions (e.g., a pre-cutoff function) to prevent performance degradation or damage to the battery cell 310. In an embodiment, the protection circuit module 400 may protect the battery cell 310 by blocking overcharging, over-discharging, or over-current.

[0065] According to an embodiment, as Figure 6a shown, the protection circuit module 400 may include a printed circuit board 410, at least one electronic component 420 disposed on the printed circuit board 410, and / or connection terminals 430 disposed on the printed circuit board 410 and connected to the electrode terminals 360. In an embodiment, the electronic component 420 may be an integrated circuit (IC) chip of the protection circuit module 400. In an embodiment, the electronic component 420 may include a first electronic component 421 and a second electronic component 422. The first electronic component 421 may be disposed on a first surface 410A of the printed circuit board 410. The second electronic component 422 may be disposed on a second surface 410B of the printed circuit board 410. In an embodiment, referring to Figure 6b ), the first surface 410A of the printed circuit board 410 may be a surface facing the first surface 330A of the first sealing portion 330. The second surface 410B of the printed circuit board 410 may be a surface opposite to the first surface 410A and may be a surface facing the counterpart of the electronic device. A first connection terminal 431 and a second connection terminal 432 may be disposed on the second surface 410B of the printed circuit board 410. In an embodiment, the connection terminals 430 may include a first connection terminal 431 connected to the first electrode tab 361 and a second connection terminal 432 connected to the second electrode tab 362. Referring to Figure 6a and Figure 6b ), the first connection terminal 431 may be disposed on the second surface 410B of the printed circuit board 410 to be electrically connected to the first electrode tab 361. The second connection terminal 432 may be disposed on the second surface 410B of the printed circuit board 410 to be electrically connected to the second electrode tab 362.

[0066] In an embodiment, the protection circuit module 400 may be electrically connected to the battery cell 310. In an embodiment, the protection circuit module 400 may be disposed adjacent to the first sealing portion 330. For example, the printed circuit board 410 of the protection circuit module 400 may be disposed on the surface (e.g., Figure 5b the first surface 330A in Figure 4bon the second surface 330B) of and adjacent to the surface of the first sealing part 330 (e.g., Figure 5b the first surface 330A) or the second surface in (e.g., Figure 4b the second surface 330B) in. Refer to Figure 6a , at least one section of the first electrode tab 361 of the battery cell 310 can be bent to connect to the first connection terminal 431 of the protection circuit module 400. Similarly, at least one section of the second electrode tab 362 of the battery cell 310 can be bent to connect to the second connection terminal 432 of the protection circuit module 400.

[0067] According to an embodiment, as electronic devices become smaller and thinner, the space occupied by the battery structure 300 within the electronic device is designed to be limited. Specifically, considering the comfort and weight perception of the user, an electronic device worn on a part of the user's body (such as a wearable electronic device) may have size limitations. Therefore, the space occupied by the battery structure 300 within the wearable electronic device can be reduced. At the same time, when implementing the battery structure 300 in a limited space, the size of the battery cell 310 is restricted. In this case, the capacity of the battery structure 300 is limited. According to an embodiment of the present disclosure, within the space occupied by the battery structure 300 in the electronic device, the space occupied by the protection circuit module 400 and / or the sealing parts 330 and 340 can be reduced. In this case, the size of the battery cell 310 can be increased by the reduced space, thereby ensuring the capacity of the battery cell 310. Hereinafter, the structure for reducing the space occupied by the protection circuit module 400 in the present disclosure will be described in detail.

[0068] In an embodiment, refer to Figure 4a and Figure 4b , the second sealing part 340 and the third sealing part 350 can be bent to face the side surface of the battery pouch 320. For example, the second sealing part 340 and the third sealing part 350 can be folded in the +z direction based on Figure 4a . As will be described later, the first sealing part 330 can also be folded in the +z direction together with the second sealing part 340 and the third sealing part 350 based on Figure 4a . Therefore, the first sealing part 330, the second sealing part 340, and the third sealing part 350 (which are the remaining parts of the battery pouch 320 remaining after sealing the battery cell 310) can occupy a reduced space within the electronic device.

[0069] According to an embodiment, as shown in Figure 4a , Figure 4b and Figure 4c , the first sealing part 330 of the battery pouch 320 can be formed in a bent shape and can include at least one groove 331. In an embodiment, when based onFigure 4b When observing the battery pouch 320 in the +y direction, the first sealing portion 330 may have a shape that is repeatedly formed shapes, shapes and / or a "U" shape. Alternatively, the first sealing portion 330 may include shapes, shapes and / or at least one of "U" shapes. In an embodiment, the groove 331 of the first sealing portion 330 may be a concave space formed due to the curved shape of the first sealing portion 330, such as shapes, shapes and / or a "U" shape.

[0070] In an embodiment, the first sealing portion 330 may have a shape that is bent by being squeezed by a jig (not shown). Referring to Figure 4a , Figure 4b and Figure 4c , at least one groove 331 may be formed in the area squeezed by the jig. During the sealing process, the first sealing portion 330 may be squeezed by placing a jig having a curved shape on the first surface 330A and the second surface 330B of the first sealing portion 330, thereby forming a groove 331 on the first surface 330A and / or the second surface 330B. In addition, the groove 331 may be formed in the first sealing portion 330 by various processes.

[0071] As will be described later, at least a part of the electronic components provided in the protection circuit module 400 may be located in the groove 331 of the first sealing portion 330. In an embodiment, at least one of the first electronic component 421, the second electronic component 422, the first connection terminal 431, or the second connection terminal 432 of the protection circuit module 400 may be provided in the groove 331. For example, referring to Figure 6b , the protection circuit module 400 may be in close contact with the first surface 330A of the first sealing portion 330 such that the first electronic component 421 provided on the first surface 410A of the printed circuit board 410 is located in the groove 331 of the first sealing portion 330.

[0072] According to an embodiment, as shown in Figure 5a and Figure 5b , the first sealing portion 330 may be processed into a curved shape in which a groove 331 is formed, and then bent to face the battery cell 310. For example, based on Figure 5b , the first sealing portion 330 may be folded in the +z direction. Therefore, the space occupied by the first sealing portion 330 in the area where the battery structure 300 is provided in the electronic device can be reduced. At the same time, the first sealing portion 330 may be separated from the second sealing portion 340 and the third sealing portion 350 to allow folding.

[0073] In the embodiments, reference Figure 4c The groove 331 formed in the first sealing portion 330 may be spaced apart from the end of the battery bag 320 forming the receiving portion 321 by a predetermined distance L1 so that the first sealing portion 330 may be folded in the +z direction. Therefore, the first sealing portion 330 may be bent to face the battery cell 310.

[0074] According to an embodiment, the protective circuit module 400 may be disposed on the first sealing portion 330. In an embodiment, referring to Figure 6a and Figure 6b In the first sealing portion 330 based on Figure 6a The protection circuit module 400 may be disposed on the first surface 330A of the first sealing portion 330 in a state of being folded in the +z direction to face the side surface of the battery pouch 320. Figure 6b , the protection circuit module 400 may be arranged so that the first electronic component 421 is located in the groove 331 formed on the first surface 330A of the first sealing portion 330. For example, the printed circuit board 410 may be arranged so that the first surface 410A on which the first electronic component 421 is arranged faces the first surface 330A of the first sealing portion 330. The second electronic component 422 arranged on the second surface 410B of the printed circuit board 410 may face the counterpart of the electronic device instead of the first sealing portion 330. In this case, the first electronic component 421 may be arranged in the groove 331 of the first sealing portion 330 to be protected from the surrounding environment. Therefore, the first electronic component 421 may be located in the groove 331 of the first sealing portion 330 to be protected from the impact of the external impact applied to the electronic device. In addition, in the protection circuit module 400, since the first electronic component 421 is located in the groove 331 of the first sealing portion 330, the space occupied by the first electronic component 421 in the electronic device can be reduced. Therefore, the size of the battery cell 310 may be increased by the space previously occupied by the first electronic component 421 , thereby ensuring additional capacity of the battery cell 310 .

[0075] In an embodiment not shown in the figures, the protection circuit module 400 may be disposed in a space defined between the first sealing portion 330 and the accommodating portion 321. In an embodiment, a groove (not shown) may be formed on the second surface 330B of the first sealing portion 330. The protection circuit module 400 may be disposed such that the first electronic component 421 or the second electronic component 422 is located in the groove formed on the second surface 330B of the first sealing portion 330. In an embodiment, the protection circuit module 400 may be disposed such that the first electronic component 421 is located in the groove formed on the second surface 330B of the first sealing portion 330. For example, the printed circuit board 410 may be disposed such that the first surface 410A on which the first electronic component 421 is disposed faces the second surface 330B of the first sealing portion 330. In some embodiments, the protection circuit module 400 may be disposed such that the second electronic component 422 is located in the groove formed on the second surface 330B of the first sealing portion 330. For example, the printed circuit board 410 may be disposed such that the second surface 410B on which the second electronic component 422 is disposed faces the second surface 330B of the first sealing portion 330. Accordingly, the printed circuit board 410 may be located inside the first sealing portion 330, and the electronic components 421 and 422 may be located in the grooves of the first sealing portion 330, thereby being protected from external shocks applied to the electronic device. Since the first electronic component 421 or the second electronic component 422 of the protection circuit module 400 is located in the groove of the first sealing portion 330, the space occupied by the electronic components 421 and 422 in the electronic device may be reduced. Accordingly, the size of the battery cell 310 may be increased by up to the space previously occupied by the first electronic component 421 and 421, thereby ensuring an additional capacity of the battery cell 310.

[0076] In an embodiment not shown in the figures, at least one of the first connection terminal 431 and the second connection terminal 432 may be located in the groove 331 formed on the first surface 330A of the first sealing portion 330. Alternatively, in some embodiments, at least one of the first connection terminal 431 and the second connection terminal 432 may be located in the groove formed on the second surface 330B of the first sealing portion 330. Accordingly, at least one of the first connection terminal 431 and the second connection terminal 432 may be protected from external shocks applied to the electronic device. In addition, since the first connection terminal 431 or the second connection terminal 432 of the protection circuit module 400 is located in the groove of the first sealing portion 330, the space occupied by the connection terminals 431 and 432 in the electronic device may be reduced. Accordingly, the size of the battery cell 310 may be increased by up to the space previously occupied by the connection terminals 431 and 432, thereby ensuring an additional capacity of the battery cell 310.

[0077] Hereinafter, for ease of explanation, it will be assumed that the protection circuit module 400 is arranged such that the first electronic component 421 provided on the first surface 410A of the printed circuit board 410 is located in the groove 331 formed on the first surface 330A of the first sealing portion 330, and the first surface 330A of the first sealing portion 330 faces the first surface 310A of the first sealing portion 330.

[0078] Meanwhile, as described above, when the protection circuit module 400 is located in the space formed between the first sealing portion 330 and the accommodation portion 321, the groove 331 formed on the second surface 330B of the first sealing portion 330 may be additionally spaced apart from the end of the battery pouch 320 forming the accommodation portion 321 by a predetermined distance L1 and a distance corresponding to the thickness of the printed circuit board 410, so as to allow the first sealing portion 330 to fold in Figure 4c the +z direction.

[0079] According to an embodiment, as Figure 6a and Figure 6b shown, since the first electronic component 421 of the protection circuit module 400 is located in the groove 331 of the first sealing portion 330, the space occupied by the first electronic component 421 in the electronic device can be reduced. In the embodiment, when the first electronic component 421 is located in the groove 331, the length of the battery structure 300 in the y-axis direction can be based on Figure 6a and reduced. For example, when the groove 331 is not formed in the first sealing portion 330, the distance from one end of the battery pouch 320 to the end of the second electronic component 422 of the protection circuit module 400 may be about 5.7 mm. In contrast, as Figure 6a and Figure 6b shown, when the first electronic component 421 of the protection circuit module 400 is located in the groove 331 of the first sealing portion 330, the distance L2 from the one end of the battery pouch 320 forming the accommodation portion 321 to the second electronic component 422 of the protection circuit module 400 can be reduced to about 4.2 mm. In this case, since the space occupied by the first electronic component 421 is reduced by the groove 331 of the first sealing portion 330, the size of the battery cell 310 can be increased, thereby increasing the capacity of the battery cell 310.

[0080] In the embodiment, referring to Figure 6a and Figure 6b, the protection circuit module 400 may be disposed on the first surface 330A or the second surface 330B of the first sealing portion 330 to be electrically connected to the electrode terminal 360 of the battery structure 300. In an embodiment, at least one section of the first electrode tab 361 of the battery structure 300 may be bent to be connected to the first connection terminal 431 disposed on the printed circuit board 410 of the protection circuit module 400. Similarly, at least a portion of the second electrode tab 362 of the battery structure 300 may be bent to be connected to the second connection terminal 432 disposed on the printed circuit board 410 of the protection circuit module 400.

[0081] Figure 7 is a view for comparing and describing the battery structure 300 of the present disclosure with the battery structure 300 according to another embodiment.

[0082] Hereinafter, a state before the space occupied by the protection circuit module 400 is reduced within the space occupied by the battery cell 310 in an electronic device (e.g., Figure 1 the electronic device 101 therein) will be described (e.g., Figure 7 (a) of Figure 7 ), and the structural difference from the state after the space occupied by the protection circuit module 400 is reduced (e.g., (b) of

[0083] Figure 7 In an embodiment, referring to Figure 7 (a) of Figure 1 , the first sealing portion 330 may be disposed in a direction parallel to the extending direction of the battery structure 300 (e.g., the y-axis direction of

[0084] Figure 7 (b) of Figure 7 ), which shows an embodiment of the present disclosure, the first sealing portion 330 may be processed into a bent shape in which a groove 331 is formed, and then may be bent to face the side surface of the battery pouch 320. For example, the first sealing portion 330 may be folded in the +z direction based on Figure 7Compared with (a) thereof, the space occupied by the first sealing part 330 within the electronic device can be reduced. In addition, the protection circuit module 400 can be disposed on the first surface 330A of the first sealing part 330 to be electrically connected to the electrode terminal 360 of the battery structure 300. Since the printed circuit board 410 of the protection circuit module 400 is disposed on the first sealing part 330 such that the first electronic component 421 is located in the groove 331 of the first sealing part 330, the space occupied by the first electronic component 421 can be reduced. In summary, compared with Figure 7 in (a) thereof, Figure 7 in the embodiment shown in (b) thereof, since the first sealing part 330 is folded to be oriented in the +z direction and the first electronic component 421 is located in the groove 331 of the first sealing part 330, the space occupied by the protection circuit module 400 within the electronic device can be reduced Figure 7 in Y thereof.

[0085] In the embodiment, a space Y can be ensured, and this space Y corresponds to the difference between Figure 7 space Y1 from one end of the battery pouch 320 to one end of the protection circuit module 400 in (a) thereof and Figure 7 space Y2 from one end of the battery pouch 320 to one end of the protection circuit module 400 in (b) thereof. Accordingly, the size of the battery cell 310 can be increased by the reduced space Y, thereby ensuring the capacity of the battery cell 310. In the embodiment, compared with Figure 7 the battery structure 300 shown in a, Figure 7 the battery structure 300 shown in (b) thereof can ensure an additional capacity of about 5% to 8% for the battery cell 310. The above description can also be applicable to the case where the protection circuit module 400 is located in the space formed between the accommodation part 321 and the first sealing part 330 to be disposed on the second surface 330B of the first sealing part 330.

[0086] Meanwhile, in the case of a wearable electronic device, its size may be smaller compared with a portable electronic device (e.g., a smart phone or a laptop computer). Similarly, the battery structure 300 disposed within the wearable electronic device can be relatively smaller than the battery structures 300 used in electronic devices such as smart phones and laptop computers. When the battery structure 300 has a small size, such as in a wearable electronic device, even a partial reduction in the space occupied by the first sealing part 330 and the protection circuit module 400 will result in a relatively high proportion of the additional ensured space for increasing the battery cell 310 within the total size of the battery structure 300.

[0087] Although the above description assumes that the battery structure 300 is used for a wearable electronic device, the present disclosure is not limited thereto. For example, the battery structure 300 of the present disclosure can be applied to various types of electronic devices, such as a laptop computer, a smartphone, or a tablet computer.

[0088] According to an embodiment of the present disclosure, an electronic device 101 may include: a battery cell 310; a battery pouch 320 that seals the battery cell, the battery pouch including a receiving portion 321 in which the battery cell is disposed and a first sealing portion 330 that is bent to face the battery cell and includes at least one groove 331; electrode terminals 360, including a first electrode tab 361 connected to the positive electrode plate of the battery cell and led out to the first sealing portion and a second electrode tab 362 connected to the negative electrode plate of the battery cell and led out to the first sealing portion; and a protection circuit module 400 (e.g., a battery protection circuit 240), including at least one electronic component 420, and disposed on the first sealing portion such that the electronic component is located in the groove of the first sealing portion, and the protection circuit module is connected to the electrode terminals.

[0089] The protection circuit module may include a printed circuit board 410 and connection terminals 430 disposed on the printed circuit board, and the electronic components are disposed on the printed circuit board 410. The connection terminals may include a first connection terminal 431 connected to the first electrode tab and a second connection terminal 432 connected to the second electrode tab.
