[0100] According to one embodiment of the present disclosure, the first electrode lead (351) may include a connecting portion (351a) connected to the first electrode tabs (361). The first electrode lead (351) may include a through portion (351b) penetrating the first hole (331) of the gasket (330). The through portion (351b) may extend from the connecting portion (351a). The first electrode lead (351) may include a bent portion (351c) bent from the through portion (351b) toward a side wall (e.g., the first side wall (321)). The descriptions regarding the connecting portion (351a), the through portion (351b), and the bent portion (351c) of the first electrode lead (351) may be substantially equally applied to the second electrode lead (352). For example, the second electrode lead (352) may include a connecting portion connected to the second electrode tabs (362), a penetrating portion penetrating the second hole (332) of the gasket (330), and a bent portion bent from the penetrating portion of the second electrode lead (352).

[0101] According to one embodiment of the present disclosure, the battery (250) may include a protection circuit module (340) including protective circuitry electrically connected to at least one of the first electrode lead (351) and the second electrode lead (352). As an example, each of the first electrode lead (351) and the second electrode lead (352) may be electrically connected to the protection circuit module (340). The protection circuit module (340) may be configured to protect the battery cell (300) from overcharge and overdischarge, and to protect the battery cell (300) from short circuit and overcurrent.

[0102] According to one embodiment of the present disclosure, the protection circuit module (340) may include a connector pin (341) that contacts at least one of the first electrode lead (351) and the second electrode lead (352). The protection circuit module (340) may include a circuit board (342) on which protective circuitry is arranged. The connector pin (341) may be electrically connected to the circuit board (342). The protection circuit module (340) may include a flexible substrate (343) connected to the circuit board (342). A connector (344) may be arranged at an end of the flexible substrate (343). As an example, the protection circuit module (340) can be connected to the first electrode lead (351) and the second electrode lead (352) through the connector pin (341), and can be connected to other components (e.g., the printed circuit board (240) of FIG. 4) inside the electronic device (101) through the connector (344).

[0103] According to one embodiment of the present disclosure, the protection circuit module (340) may include a circuit board (342), and the circuit board (342) may be connected to a flexible substrate (343). The circuit board (342) may include a rigid area in which protective circuitry related to charging or discharging of the battery (250) is disposed. The flexible substrate (343) may be a flexible area and may be connected to a printed circuit board (or substrate assembly) (240) of the electronic device (101, see FIG. 4). An insulating cover (345) may at least partially surround the protection circuitry.

[0104] According to one embodiment of the present disclosure, the protection circuit module (340) may include an insulating cover (345). The insulating cover (345) may be disposed on a circuit board (342). The insulating cover (345) may cover a connection portion between the circuit board (342) and the flexible substrate (343). The protection circuit module (340) may further include an insulating tape (not shown). The insulating tape may wrap around the outside of the insulating cover (345) and adhere to the container (320) and the cover (310), thereby stably fixing the protection circuit module (340) to the battery cell (300).

[0105] According to one embodiment of the present disclosure, the gasket (330) and the battery housing (301) may be formed of different materials. The battery housing (301) may be at least partially conductive. For example, the gasket (330) may be an insulator (e.g., rubber), and the battery housing (301) (e.g., container (320)) may be a conductive member (e.g., stainless steel). Accordingly, the electrical connection between the electrode leads (351, 352) and the battery housing (301) (e.g., container (320)) may be blocked by the gasket (330), and the polarity of the battery housing (301) may be removed, thereby inhibiting corrosion of the battery housing (301).

[0106] According to one embodiment of the present disclosure, an insulating material may be coated on the inner surface of the battery housing (301). As an example, a paint including an insulating material may be coated (formed) on the outer surface of the container (320) and the cover (310) of the battery housing (301). A coating layer made of an insulating material coated on the inner surface of the battery housing (301) may be referred to as an insulating coating. By the insulating coating, electrical connection between the first electrode plates (371) and the second electrode plates (372) disposed inside the battery housing (301) and the container (320) or the cover (310) may be blocked.

[0107] According to one embodiment of the present disclosure, by using a single gasket (330) as an insulating structure of the electrode leads (351, 352), the number of components constituting the insulating structure can be reduced compared to the case where the insulating structure is applied to each of the electrode leads (351, 352), and thus, the assembly process of the insulating structure of the electrode leads (351, 352) can be simplified. As an example, the process of electrically connecting the electrode leads (351, 352) by welding them inside the battery housing (301) has difficulties in the process due to the limited size of the battery cell, but in the battery cell (300) of the present invention, the two electrode leads (351, 352) are drawn out of the battery cell (300) through a gasket (330) that is easy to assemble (or place), and thus the difficulties in the process due to the limited size of the battery cell can be solved.

[0108] In addition, according to one embodiment of the present disclosure, since the electrode leads (351, 352) of the battery cell (300) are extended to the outside of the battery cell (300) through the gasket (330), the insulating structure of the electrode leads (351, 352) that were arranged inside the existing battery cell (300) can be removed, and accordingly, the size of the electrode plates (370) arranged in the battery cell (300) can be increased, and the energy density of the battery cell (300) can be improved.
