BACKGROUND
Field

Various embodiments of the disclosure relate to an electronic device including a ring-shaped battery.

Description of Related Art

Electronic devices may refer to device configured to perform specific functions according to installed programs, such as home appliances, electronic wallets, portable multimedia players, mobile communication terminals, tablet PCs, video/audio devices, desktop/laptop computers, and vehicle navigation systems. For example, such electronic devices may output stored information as characters, sounds and/or images. In line with the high degree of integration of electronic devices and the widespread use of super-fast large-capacity wireless communication, it has recently become possible to equip a single electronic device with various functions. For example, not only a communication function, but also an entertainment function (for example, gaming), a multimedia function (for example, music/video playback), communication and security functions for mobile banking and the like, a scheduling function, and an electronic wallet function may be integrated into a single electronic device.

Recently, various formfactors of terminals have been developed in line with commercialization of mobile terminals. Devices such as wearable devices, for example, interwork with mobile terminals (for example, smartphones) and provide users with various user experiences and useful functions. Smart rings are ring-type mobile electronic devices, which interwork with smartphones and provide various functions (for example, health care, alarm). The availability and functionality (for example, screen mounting) of such small devices have increased, thereby gradually increasing the needs for long-time use after one-time charging. Methods for designing large-capacity batteries have been studied in view of such needs, and technologies for securing the maximum capacity within the limited size and for providing more efficient connection structures have been reviewed.

SUMMARY

In general, pouch-type batteries are applied to ring-shaped electronic devices (for example, smart rings), and according to such a pouch-type battery connection structure, a flexible printed circuit board (for example, flexible PCB (FPCB)) is drawn out and connected to a main board (for example, hard PCB) of a ring-shaped electronic device through a connector. The outside of the battery may include a part obtained by applying a polyurethane-based coating, which has strong adhesiveness, waterproofing, and corrosion resistance, to a side sealing portion, such that the ring-shaped electronic device can be waterproof in daily life. The current structure makes it inevitable to apply such a part in connection with equipping a super-small device (for example, ring-shaped electronic device) with a battery, and this may place a restriction on maximizing the battery capacity inside the electronic device.

Various embodiments of the disclosure may provide a ring-shaped (e.g., an annular-shaped) battery having a space which may include a circuit unit, and a ring-shaped electronic device including the ring-shaped battery. Problems to be solved by the disclosure are not limited to the above-mentioned problems, and may be variously expanded without deviating from the idea and scope of the disclosure.

According to various embodiments of the disclosure, the shape and size of spaces in which an electrode assembly and a circuit unit can be disposed inside a ring-shaped battery included in an electronic device may be formed as needed, thereby maximizing the battery capacity of the ring-shaped electronic device. In addition, an electronic device according to various embodiments of the disclosure can have an optimized disposition space by drawing out and disposing electrode tabs to a place desired by a circuit portion along the inside of a battery case of a ring-shaped battery, and implementing a power line (e.g., provided by a power contact unit).

A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the 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., 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 may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify or authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology.
