Description

Batteries and electronic devices containing them

[0001] The present disclosure relates to a battery having a pouch for accommodating an electrode assembly formed into an asymmetrical shape and an electronic device including the same.

[0002] A portable electronic device may include a housing and a battery disposed within the housing, the battery supplying power to the electronic device. The battery may include an electrode assembly that generates voltage according to the movement of electrons, and a pouch that accommodates the electrode assembly. The edges of the pouch may be sealed to insulate the electrode assembly accommodated within the pouch.

[0003] The battery is connected to the electrode assembly and may further include a protection circuit module (PCM) for protecting and controlling the battery. The protection circuit module may be located on one side of the front sealing portion. The height of the front sealing portion may vary depending on the forming shape of the pouch. For example, if the height of the front sealing portion is large (or long) depending on the forming shape of the pouch, interference may occur between the support bracket of the housing in which the battery is accommodated and the flexible printed circuit board (FPCB) connected to the protection circuit module, and a portion of the support bracket may need to be cut to avoid the interference.

[0004] Various embodiments of the present disclosure can provide a battery and an electronic device including the same, wherein the height of a front sealing portion on which a protection circuit module (PCM) is mounted can be adjusted through asymmetrical shape forming of a pouch.

[0005] An electronic device according to one embodiment of the present disclosure may include a housing. The electronic device may include a battery disposed inside the housing and supplying power to the electronic device. The battery may include an electrode assembly. The battery may include an upper pouch and a lower pouch disposed to accommodate the electrode assembly. The battery may include a sealing portion formed at an edge of the upper pouch and the lower pouch to seal the electrode assembly. The lower pouch may include a first cup that is recessed downward and accommodates at least a portion of the electrode assembly, and the first cup may have a front surface, a rear surface opposite the front surface, and a side surface connecting the front surface and the rear surface. The sealing portion may include a front sealing portion that extends from the front surface of the first cup and is positioned at a height lower than an upper end of the rear surface of the first cup.

[0006] A battery according to one embodiment of the present disclosure may include an electrode assembly. The battery may include a pouch including an upper pouch and a lower pouch for accommodating the electrode assembly, and a sealing portion formed at an edge of the upper pouch and the lower pouch to seal the electrode assembly. The lower pouch may be recessed downward and include a first cup for accommodating at least a portion of the electrode assembly. The first cup may include a front surface, a rear surface opposite the front surface, and a side surface connecting the front surface and the rear surface. The sealing portion may include a front sealing portion extending from a front portion of the first cup and positioned lower than an upper end of the rear surface of the first cup.

[0007] A pouch according to one embodiment of the present disclosure may include an upper pouch configured to accommodate at least a portion of an electrode assembly. The pouch may include a lower pouch configured to accommodate at least a portion of the electrode assembly and connected to the upper pouch. The pouch may include a sealing portion formed at edges of the upper pouch and the lower pouch to seal the electrode assembly. The lower pouch may include a first cup that is recessed downward and accommodates at least a portion of the electrode assembly. The sealing portion may include a front sealing portion that extends from a front portion of the first cup and has a height lower than a topmost height of the first cup.

[0008] Various embodiments of the present disclosure can lower the height of the front sealing portion of the pouch by forming the shape of the pouch, such as a cup, asymmetrically. Accordingly, interference between the support bracket of the housing and the FPCB connected to the protection circuit module can be reduced, thereby freeing the pouch from constraints on the structure and / or shape of the support bracket and the FPCB. In addition, since the side sealing portion is folded downward so that the insulating tape and the adhesive tape are positioned on substantially the same surface (e.g., the bottom surface of the battery), the reduction in battery capacity due to the thickness of the insulating tape can be compensated for. In addition, since the remaining folded portion near the corner that occurs when folding the side of the existing sealing portion is eliminated, the design freedom of the protection circuit module (PCM) size can be improved.

[0009] The effects that can be achieved by the exemplary embodiments of the present disclosure can be clearly derived and understood by those skilled in the art to which the exemplary embodiments of the present disclosure pertain, from the following description. In other words, unintended effects resulting from the implementation of the exemplary embodiments of the present disclosure can also be derived by those skilled in the art from the exemplary embodiments of the present disclosure.

[0040] The operating principle and embodiments of the present invention will be described with reference to the attached drawings below.

[0041] FIG. 1 is a block diagram of an electronic device within a network environment according to one embodiment of the present disclosure.

[0042] Referring to FIG. 1, in a network environment (100), an electronic device (101) may communicate with an electronic device (102) via a first network (198) (e.g., a short-range wireless communication network), or may communicate with at least one of an electronic device (104) or a server (108) via a second network (199) (e.g., a long-range wireless communication network). In one embodiment, the electronic device (101) may communicate with the electronic device (104) via the server (108). According to one embodiment, the electronic device (101) may include a processor (120), a memory (130), an input module (150), an audio output module (155), a display module (160), an audio module (170), a sensor module (176), an interface (177), a connection terminal (178), a haptic module (179), a camera module (180), a power management module (188), a battery (189), a communication module (190), a subscriber identification module (196), or an antenna module (197).

For example, when the electronic device (101) includes the main processor (121) and the auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a given function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0044] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

[0051] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0052] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) with an external electronic device (e.g., the electronic device (102)). In one embodiment, the interface (177) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0053] The connection terminal (178) may include a connector through which the electronic device (101) may be physically connected to an external electronic device (e.g., electronic device (102)). According to one embodiment, the connection terminal (178) may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0058] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one 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 module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0059] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0060] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device).

In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0061] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0062] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0063] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device.

[0065] FIG. 2 is a front perspective view of an electronic device according to one embodiment of the present disclosure. FIG. 3 is a rear perspective view of an electronic device according to one embodiment of the present disclosure.

[0066] Referring to FIGS. 2 and 3, the electronic device (200) includes a housing (210) including a front surface (210a), a rear surface (210b), and a side surface (210c) surrounding a space between the front surface (210a) and the rear surface (210b). The housing (210) may also refer to a structure forming at least one of the front surface (210a), the rear surface (210b), and the side surface (210c). Here, the term "side" may also be used interchangeably with "surface" or "surface of a side."

[0067] At least a portion of the front surface (210a) may be formed by a substantially transparent front plate (202) (e.g., a glass plate, a polymer plate, or a cover glass including various coating layers). The front plate (202) may be formed of, but is not limited to, 2D glass or 2.5D glass.

[0068] The back (210b) may be formed by a back plate (211). The back plate (211) may be formed by, for example, glass, ceramic, polymer, metal (for example, aluminum, stainless steel, or magnesium), or a combination of at least two of the above materials.

[0069] The side (210c) can be formed by a bezel (218) (or “side (210c) member”) of the side (210c) comprising metal and / or polymer in combination with the front plate (202) and the back plate (211). At least one of the bezel (218) and the front plate (202) and / or the back plate (211) can be formed integrally. For example, the bezel (218) and the front plate (202), the bezel (218) and the back plate (211), or the bezel (218) and the front and back plates (202, 211) can be formed integrally. The integrally formed bezel (218) can comprise glass, a metal material (e.g., aluminum), or ceramic. Other integrally formed components (e.g., the front plate (202) and / or the back plate (211)) can comprise substantially the same material.

[0070] The front plate (202) may include two first edge regions (210d) that extend seamlessly from two opposite ends of a long edge of the front plate (202) and are curved in a direction from the front side (210a) toward the rear side (211) (e.g., in the -Z-axis direction). The rear plate (211) may include two second edge regions (210e) that extend seamlessly from two opposite ends of a long edge of the rear plate (202) and are curved in a direction from the rear side (210b) toward the front side (202) (e.g., in the +Z-axis direction). The front plate (202) (or the rear plate (211)) may include only one of the first edge regions (210d) (or the second edge regions (210e)). At least some of the first edge regions (210d) or the second edge regions (210e) may not be included.

[0131] In this case, the installation height (or mounting height) of the protection circuit module (e.g., the protection circuit module (330) of FIG. 9) mounted on the front sealing portion (S1) can also be lowered.

[0132] For example, the height of the front sealing portion (S1) extended from the first cup (311) can be adjusted through asymmetrical shape forming of the pouch (300), for example, asymmetrical forming of the shape of the first cup (311), as described above, based on the size, arrangement and / or connection relationship of the protection circuit module (e.g., the protection circuit module (330) of FIG. 9).

[0133] According to one embodiment, the side sealing portion (S2) may be an area where the lower pouch (310) and the upper pouch (320) are folded and come into contact with each other, thereby forming a side portion of the pouch (300). In one embodiment, the side sealing portion (S2) may be formed by heat-sealing the side portion (313) of the lower pouch (310) and the side portion (323) of the upper pouch (320) after they come into contact with each other (or overlap).

[0134] According to one embodiment, the side sealing portion (S2) can be sequentially folded a predetermined number of times (e.g., twice) to face the first cup (311) of the lower pouch (310) and at least a portion of the front sealing portion (S1).

[0135] According to one embodiment, the side sealing portion (S2) may include a first side sealing portion (S2-1) facing both sides (3112) of the first cup (311) of the lower pouch (310) and a second side sealing portion (S2-2) facing the lower side of the front sealing portion (S1).

[0136] According to one embodiment, the first side sealing portion (S2-1) may correspond to a portion of the side sealing portion (S2) that is first folded downward (e.g., in the -z-axis direction) to face the two side surfaces (3112) of the first cup (311) of the lower pouch (310) (see FIGS. 12 and 13). In one embodiment, the first side sealing portion (S2-1) may have a shape corresponding to at least a portion of the two side surfaces (3112) of the first cup (311) of the lower pouch (310). In this case, the first side sealing portion (S2-1) may be arranged to overlap the side surfaces (3112) of the first cup (311) when folded.

[0137] According to one embodiment, the second side sealing portion (S2-2) may correspond to a portion of the side sealing portion (S2) that is formed by a second fold downward (e.g., in the -z-axis direction) so as to face the lower surface of the front sealing portion (S1) after the first folding of the side sealing portion (S2) (see FIGS. 13 and 14).

[0138] Fig. 9 is a perspective view illustrating a state in which a protection circuit module is connected to a battery according to one embodiment of the present disclosure. Fig. 10 is a front view illustrating a state in which a battery with a protection circuit module connected to it is installed in an electronic device according to one embodiment of the present disclosure.

[0139] Referring to FIGS. 9 and 10, a protection circuit module (330) according to one embodiment may further include a flexible printed circuit board (331) (FPCB, flexible printed circuit board) for electrically connecting an electrode assembly (not shown) of a battery (e.g., a battery (250) of FIG. 4) and a printed circuit board (240) of an electronic device (e.g., an electronic device (200) of FIG. 2).

[0140] According to one embodiment, the protection circuit module (330) may be arranged on the upper side (e.g., in the +z-axis direction) of the front sealing portion (S1) of the pouch (300). According to one embodiment, the flexible printed circuit board (331) may be bent on the upper side (e.g., in the +z-axis direction) of the front sealing portion (S1) of the pouch (300) and then extended toward the printed circuit board (240) (e.g., in the +x-axis direction). The flexible printed circuit board (331) may be arranged to face the second side sealing portion (S2-2) with respect to the front sealing portion (S1).

[0141] In this way, when the protection circuit module (330) is placed on the upper side of the front sealing portion (S1) of the pouch (300), a bending space and / or a fluid space of the flexible printed circuit board (331) can be secured on the upper side of the protection circuit module (330). In this case, interference between the flexible printed circuit board (331) and the support bracket (270) disappears, so that the problem of having to cut (or remove) a part of the support bracket (270) to secure a bending space of the flexible printed circuit board (331) does not occur, and the flexible printed circuit board (331) can be freely bent and / or fluidized within the width (or, space corresponding to the width) of the pouch (300) (specifically, within the width of the front sealing portion (S1)). The protection circuit module (330) can be placed adjacent to the bracket (270), thereby securing more length and reducing the width of the protection circuit module (330).

[0142] Referring to FIG. 10, a battery (250) according to one embodiment may be fixed to a battery slot (250s) provided in a support bracket (270) via an adhesive (P). The adhesive (P) may be attached to a bottom surface of the battery (250). According to one embodiment, the battery (250) may include an insulating member (IT) for insulating a cross-section or part of a side sealing portion (S2) cut during processing of the pouch (300) (see FIGS. 12a and 12b). The insulating member (IT) may be attached to a side surface and / or a bottom surface of the pouch (300) so as to surround an edge of the side sealing portion (S2).

[0143] In this case, since at least a part of the adhesive (P) disposed on the lower surface of the battery (250) to attach the battery (250) to the support bracket (270) and the insulating member (IT) surrounding the edge of the sealing portion (S) to insulate the battery (250) are positioned on the same plane (e.g., the lower surface of the battery (250)), the increase in the mounting space of the battery (250) in the electronic device (200) housing (specifically, the support bracket (270)) due to the thickness of the members can be reduced compared to a case where the members are separately attached to the upper and lower surfaces of the battery (250), respectively.

[0146] Hereinafter, a manufacturing process of a pouch (300) of a battery (e.g., battery (250) of FIG. 4) will be described with reference to FIGS. 11 to 16b.

[0147] Referring to FIGS. 11 to 16b, in one embodiment, the outer material of the pouch (300) may be formed using a forming device (not shown) to form an asymmetrically shaped lower pouch (e.g., the lower pouch (310) of FIG. 6) and an upper pouch (e.g., the upper pouch (320) of FIG. 6) (process 1110).

[0148] According to one embodiment, the sealing portion (S) of the pouch (300) can be formed by folding the lower pouch (310) and the upper pouch (320) along a folding line (e.g., folding line (F1-F1') of FIG. 6) to bring the lower pouch (310) and the upper pouch (320) into contact with each other, and then heat-welding the edges of the upper / lower pouches (310, 320) (process 1120).

[0149] According to one embodiment, the sealing length (hereinafter, width) (W') of the sealing portion (S') of the pouch (300') may be cut to a predetermined portion to fit a preset width (W) (process 1130). Here, the preset width (W) of the pouch (300) may be set in consideration of the size of the battery (250) and / or the size of the battery slot (250s) of the support member (272). For example, the width (W') of the sealing portion (S') of the pouch (300') may be cut to a predetermined width (W) such that, when the side sealing portion (S2) described below is folded, at least a portion (e.g., the first side sealing portion (S2-1)) of the side sealing portion (S2) faces at least a portion of the side surface (3112) of the first cup (311) of the lower pouch (310) (see FIGS. 12a and 12b).

[0150] According to one embodiment, in order to reduce the size of the pouch (300), the side sealing portion (S2) of the pouch (300) may be folded to one side a predetermined number of times (process 1140). In one embodiment, the side sealing portion (S2) of the pouch (300) may be folded downward (e.g., in the -z-axis direction) to face the side surface (3112) of the first cup (311) of the lower pouch (310) (see FIG. 13). Thereafter, the second side sealing portion (S2-2) of the side sealing portion (S2) is folded downward once more (e.g., in the -z-axis direction) along the folding line (F2-F2') to face the back surface of the front sealing portion (S1) (see FIG. 14).

[0151] In this case, in contrast to the case where a residual folded portion (S3) (e.g., a dog ear portion) is generated at the corner of the pouch (300") when the side sealing portion (S2") is folded in the pouch (300") structure of a general battery as illustrated in FIG. 15a, and the residual folded portion (S3) is positioned on the inside of the front sealing portion (S1"), since the pouch (300) is formed into an asymmetrical shape, the residual folded portion (S3) of the pouch (300") as illustrated in FIG. 15a can be omitted (see FIG. 16a), thereby providing additional freedom in the size (e.g., width) of the protection circuit module (330) mounted on the front sealing portion (S1). For example, the width (L) of the protection circuit module (330) illustrated in FIG. 16b can be designed to be larger than the width (L') of the protection circuit module (330") illustrated in FIG. 15b.

[0152] According to one embodiment, at the edge of the sealing portion (S), the edge of the side sealing portion (S2) may be wrapped by an insulating member (e.g., the insulating member (IT) of FIG. 10) to insulate the battery (250) (process 1150).
