The third adhesive region (343) may be an edge region of the third cover portion (340) spaced apart from the main cover portion (310).

[0122] According to one embodiment, the third-first extension region (341) and the third-second extension region (342) of the third cover portion (340) may be non-adhesive surfaces. The third adhesive region (343) of the third cover portion (340) may have a greater adhesive force than the first region (311a) of the main cover portion (310). The adhesive force of the third adhesive region (343) may be approximately 0.8 kgf to 1.2 kgf. For example, the adhesive force of the third adhesive region (343) may be approximately 1.0 kgf.

[0123] According to one embodiment, when looking at the front of the battery assembly (40), the first cover portion (320), the second cover portion (330), and the third cover portion (340) may be arranged so as not to overlap each other. When looking at the front of the battery assembly (40), the first cover portion (320), the second cover portion (330), and the third cover portion (340) may be arranged so as to be spaced apart from each other. For example, the first adhesive region (323) of the first cover portion (320) may be in a state where a portion adjacent to the left edge (e.g., the -X-axis direction edge) of the front surface (410a) of the battery cell (410) is adhered, the second adhesive region (333) of the second cover portion (330) may be in a state where a portion adjacent to the right edge (e.g., the +X-axis direction edge) of the front surface (410a) of the battery cell (410) is adhered, and the third adhesive region (343) of the third cover portion (340) may be in a state where a portion adjacent to the upper edge (e.g., the +Y-axis direction edge) of the front surface (410a) of the battery cell (410) is adhered.

[0124] According to one embodiment, the fourth cover portion (350) of the cover member (300) may extend from the lower end of the main cover portion (310) and may be arranged to surround at least a portion of the front surface (410a) of the battery cell (410) from the lower edge (414) of the battery cell (410) (e.g., the edge in the -Y-axis direction). The extension direction of the fourth cover portion (350) may be substantially perpendicular to the first cover portion (320) and / or the second cover portion (330). The extension direction of the fourth cover portion (350) may be opposite to the extension direction of the third cover portion (340).

The fourth-second extension region (352) may be spaced apart from the main cover portion (310) with the battery cell (410) therebetween.

[0126] According to one embodiment, the 4-1 extension region (351) and the 4-2 extension region (352) of the 4th cover portion (350) may be non-adhesive surfaces. The 4-2 extension region (352) of the 4th cover portion (350) may have a width extending from a portion adjacent to one edge (411) of the battery cell (410) to a portion adjacent to the other edge (412). Accordingly, when looking at the front of the battery assembly (40), the 4-2 extension region (352) may be arranged to overlap a portion of the 1st cover portion (320) (e.g., the first adhesive region (323)) and a portion of the 2nd cover portion (330) (e.g., the second adhesive region (333)). The 4-2 extension region (352) of the 4th cover portion (350) may have a length extending to the upper edge (413) of the battery cell (410). Accordingly, when looking at the front of the battery assembly (40), the 4-2 extension region (352) may be arranged to overlap with a part of the 3rd cover portion (340) (e.g., the 3rd adhesive region (343)). In one embodiment, the 4-2 extension region (352) of the 4th cover portion (350) may include a 4th adhesive region (not shown).

[0127] According to one embodiment, the 4-2 extension region (352) of the 4th cover portion (350) may be positioned below the first adhesive region (323) of the first cover portion (320), the second adhesive region (333) of the second cover portion (330), and the third adhesive region (343) of the third cover portion (340). After the 4-2 extension region (352) forming a non-adhesive surface on the front surface (410a) of the battery cell (410) is positioned, the first adhesive region (323), the second adhesive region (333), and the third adhesive region (343) are adhered to each edge of the 4-2 extension region (352), so that the cover member (300) may be positioned to completely surround each side surface of the battery cell (410) without directly adhering to the battery cell (410).

[0128] According to one embodiment, the cover member (300) may be formed integrally, and the first cover portion (320), the second cover portion (330), the third cover portion (340), and the fourth cover portion (350) may be arranged to extend from the main cover portion (310). At least one of the first cover portion (320), the second cover portion (330), the third cover portion (340), and the fourth cover portion (350) may include an adhesive area (323, 333, 343) that can be bonded to the front surface (410a) of the battery cell (410). The adhesive area (323, 333, 343) may be an area that includes an adhesive member in a designated area of ​​the cover member (300). In one embodiment, at least one of the first cover portion (320), the second cover portion (330), the third cover portion (340), and the fourth cover portion (350) may include a pull tab (not shown). For example, the pull tab (not shown) area may be an area extending in the opposite direction of the main cover portion (310) from the adhesive area (323, 333, 343) in the cover portions (320, 330, 340, 350).

[0129] Hereinafter, with reference to FIGS. 6 to 7d, the process of the cover member (300) covering the battery cell (410) will be described.

[0130] First, referring to FIG. 6, when the cover member (300) is unfolded, a battery protection circuit (420), a flexible circuit board (430), and a battery cell (410) assembled therewith can be placed on the inner surface (311) of the main cover portion (310) of the cover member (300). The main cover portion (310) of the cover member (300) can substantially cover the mounting surface of the battery cell (410) (e.g., the surface facing the mounting groove (211a) of the housing (110).

[0131] Hereafter, referring to FIG. 7a, the fourth cover portion (350) extending downward (e.g., in the -Y-axis direction) of the main cover portion (310) of the cover member (300) may be arranged to cover the front surface (410a) of the battery cell (410) from the lower edge (414) of the battery cell (410). For example, the 4-1 extension region (351) of the fourth cover portion (350) may contact and cover the lower edge (414) of the battery cell (410), and the 4-2 extension region (352) of the fourth cover portion (350) may contact and cover the front surface (410a) of the battery cell (410). The 4-2 extension region (352) of the fourth cover portion (350) may be arranged to exclude both edge portions of the battery cell (410). The 4-2 extension area (352) of the 4th cover portion (350) can be arranged excluding the battery protection circuit (420) and flexible circuit board (430) arranged on the upper side of the battery cell (410).

[0132] Hereafter, referring to FIG. 7b, a third cover portion (340) extending upwardly (e.g., in the +Y-axis direction) of the main cover portion (310) of the cover member (300) may be arranged to cover at least a portion of the battery cell (410) and the battery protection circuit (420) assembled on the upper end of the battery cell (410). For example, the 3-1 extension region (341) of the third cover portion (340) may contact and cover an upper edge of the battery protection circuit (420), and the 3-2 extension region (342) and the third adhesive region (343) of the third cover portion (340) may contact and cover a front surface of the battery protection circuit (420) and a portion of the front surface (410a) of the battery cell (410). A portion of the third-second extension region (342) and / or the third adhesive region (343) may be disposed on the fourth cover portion (350). The third adhesive region (343) may be adhered onto the fourth cover portion (350).

[0133] Hereafter, referring to FIG. 7c, a first cover portion (320) extending to the left side (e.g., in the -Y-axis direction) of the main cover portion (310) of the cover member (300) may be arranged to cover a portion of the front surface (410a) of the battery cell (410) from one edge (411) of the battery cell (410). For example, the 1-1 extension region (321) of the first cover portion (320) may contact and cover the one edge (411) of the battery cell (410), and the 1-2 extension region (322) and / or the first adhesive region (323) of the first cover portion (320) may contact and cover the front surface (410a) of the battery cell (410). A portion of the 1-2 extension region (322) and the first adhesive region (323) may be arranged on the 4th cover portion (350). The first adhesive area (323) can be adhered on the fourth cover portion (350). The first adhesive area (323) can be spaced apart from the third adhesive area (343).

[0134] Hereafter, referring to FIG. 7d, a second cover portion (330) extending to the right side (e.g., in the +Y-axis direction) of the main cover portion (310) of the cover member (300) may be arranged to cover a portion of the front surface (410a) of the battery cell (410) from the other edge (412) of the battery cell (410). For example, the 2-1 extension region (331) of the second cover portion (330) may contact and cover the other edge (412) of the battery cell (410), and the 2-2 extension region (332) and / or the second adhesive region (333) of the second cover portion (330) may contact and cover the front surface (410a) of the battery cell (410). A portion of the 2-2 extension region (332) and the second adhesive region (333) may be arranged on the fourth cover portion (350). The second adhesive region (333) can be adhered on the fourth cover portion (350). The second adhesive region (323) can be spaced apart from the first adhesive region (323) and the third adhesive region (343).

[0135] Referring to FIGS. 7b, 7c, and 7d, the cover member (300) is disclosed in the order of covering the upper, left, and right edges of the battery cell (410), but is not limited thereto, and the design may be changed in various orders for easy covering of the battery cell (410).

[0136] According to one embodiment, since the first adhesive region (323), the second adhesive region (333), and the third adhesive region (343) are adhered to the fourth cover portion (350), all edges of the battery cell (410) can be covered by the cover member (300), and adhesion between the battery cell (410) and the cover member (300) can be excluded. Accordingly, when the cover member (300) is detached from the battery cell (410) for reuse of the battery cell (410), deformation (e.g., bending) of the battery cell (410) may not occur since the cover member (300) is not directly adhered to the battery cell (410) or has a weak adhesive force.

[0137] FIG. 8a is a drawing of a side (e.g., an inner surface) facing a first direction of a battery cover member (300a) according to an embodiment of the present disclosure.

[0138] FIG. 8b is a view of a surface (e.g., an outer surface) facing a second direction opposite to the first direction of a battery cover member (300a) according to an embodiment of the present disclosure.

[0139] FIG. 9a is a drawing of a side (e.g., an inner surface) facing a first direction of a battery cover member (300b) according to an embodiment of the present disclosure.

[0140] FIG. 9b is a drawing of a side (e.g., an outer side) facing a second direction opposite to the first direction of a battery cover member (300b) according to an embodiment of the present disclosure.

[0141] FIG. 10a is a drawing of a side (e.g., an inner surface) facing a first direction of a battery cover member (300c) according to an embodiment of the present disclosure.

[0142] FIG. 10b is a drawing of a side (e.g., an outer side) facing a second direction opposite to the first direction of a battery cover member (300c) according to an embodiment of the present disclosure.

[0143] According to one embodiment, the battery cover member (300a; 300b; 300c) is a member for covering a battery cell (e.g., a battery cell (410) of FIG. 6), and may include a main cover portion (310), a first cover portion (320) extending from the main cover portion (310) to one side, a second cover portion (330) extending from the main cover portion (310) to the other side, a third cover portion (340) extending from the main cover portion (310) in a direction perpendicular to the extension direction of the first cover portion (320) and the second cover portion (330), and a fourth cover portion (350) extending from the main cover portion (310) in a direction opposite to the third cover portion (340).

[0144] The configuration of the battery cover member (300a; 300b; 300c) of FIGS. 8a to 10b may be partially or entirely identical to the configuration of the battery cover member (300) of FIGS. 5a to 7d. The embodiments of FIGS. 8a to 10b may be optionally combined with the embodiments of FIGS. 10a to 16b.

[0145] Below, a description will be given focusing on a configuration different from that of the battery cover member (300) of FIGS. 5 to 7d.

[0146] According to one embodiment, the main cover portion (310) is arranged to surround at least a portion of the rear surface of the battery cell (410) (e.g., a surface where the battery cell (410) faces the mounting groove (e.g., the mounting groove (211a) of FIG. 4B)) and may include an inner surface (311) facing the battery cell (410) and an outer surface (312) opposite the inner surface (311). The inner surface (311) of the main cover portion (310) is arranged to directly contact the rear surface of the battery cell (410), and the outer surface (312) of the main cover portion (310) may be arranged to adhere to the mounting groove (211a) of the housing (110). The inner surface (311) of the main cover portion (310) may be formed as a weak adhesive surface (e.g., an adhesive surface having an adhesive force of approximately 0.3 Kgf to 0.5 Kgf) or may be a non-adhesive surface.

[0147] According to one embodiment, the first cover portion (320) of the cover member (300a; 300b; 300c) may extend from one end of the main cover portion (310) and may be arranged to surround a portion of the front surface of the battery cell (410) from one edge of the battery cell (410) (e.g., an edge in the -X-axis direction). The first cover portion (320) may include a first adhesive area (323) formed at the edge in the one direction (e.g., the -X-axis direction) and having a greater adhesive force than the main cover portion (310) (e.g., an adhesive force of approximately 0.8 Kgf to 1.2 Kgf).

[0148] According to one embodiment, a portion of an edge (e.g., a first adhesive region (323)) in one direction (e.g., a -X-axis direction) of the first cover portion (320) may have an inclined shape (S1). For example, with respect to an outer edge (e.g., a -X-axis direction edge) of the first cover portion (320) extending from the main cover portion (310), an upper corner (e.g., a corner facing the +Y-axis) may include a shape inclined at a specified angle. For example, with respect to a rectangle (e.g., a square or rectangle) extending from the main cover portion (310) in one direction (e.g., a -X-axis direction), the upper corners of the first cover portion (320) may have a partially fine (e.g., a cut, concave, or stepped) shape. Unlike the slanted shape of the upper edge (S1), the lower edge (e.g., the edge facing the -Y axis) can be substantially orthogonal.

[0149] According to one embodiment, according to the slanted shape (S1) of the upper edge of the first cover portion (320), when the first adhesive area (323) is adhered onto the fourth cover portion (350), it can be adhered closer and more widely to the center of the fourth cover portion (350) without overlapping with the third adhesive area (343). When the first adhesive area (323) and the third adhesive area (343) are adhered, the first adhesive area (323) and the third adhesive area (343) can be spaced apart from each other, and their respective slanted edges can be arranged in parallel.

[0150] According to one embodiment, the second cover portion (330) of the cover member (300a; 300b; 300c) may extend from the other end of the main cover portion (310) and may be arranged to surround a portion of the front surface (410a) of the battery cell (410) from the other edge (e.g., the +X-axis direction edge) of the battery cell (410). The second cover portion (330) may include a second adhesive region (333) formed at the edge in the other direction (e.g., the +X-axis direction) and having a greater adhesive force (e.g., an adhesive force of approximately 0.8 Kgf to 1.2 Kgf) than the main cover portion (310).

[0151] According to one embodiment, a portion of an edge (e.g., a second adhesive area (333)) in the other direction (e.g., the +X-axis direction) of the second cover portion (330) may have an inclined shape (S2). For example, with respect to an outer edge (e.g., an edge in the +X-axis direction) of the second cover portion (330) extending from the main cover portion (310), an upper corner (e.g., an edge facing the +Y-axis) may include a shape inclined at a specified angle. For example, the second cover portion (330) may have a shape in which some of the upper vertices are fine (e.g., cut, concave, or stepped) with respect to a rectangle (e.g., a square or rectangle) extending in one direction (e.g., the +X-axis direction) from the main cover portion (310). Unlike the slanted shape of the upper edge (S2), the lower edge (e.g., the edge facing the -Y axis) can be substantially orthogonal.

[0152] According to one embodiment, according to the slanted shape (S2) of the upper edge of the second cover portion (330), when the second adhesive area (333) is adhered on the fourth cover portion (350), it can be adhered closer and more widely to the center of the fourth cover portion (350) without overlapping with the third adhesive area (343). When the second adhesive area (333) and the third adhesive area (343) are adhered, the second adhesive area (333) and the third adhesive area (343) can be spaced apart from each other, and their respective slanted edges can be arranged in parallel. The slanted shape (S2) of the upper edge of the second cover portion (330) and the slanted shape (S1) of the upper edge of the first cover portion (320) can be left-right reversed shapes of each other.

[0153] According to one embodiment, the third cover portion (340) of the cover member (300a; 300b; 300c) may extend from the top of the main cover portion (310) and may be arranged to surround a portion of the front surface (410a) of the battery cell (410) from an upper edge (e.g., an edge in the +Y-axis direction) of the battery cell (410). The third cover portion (340) may include a third adhesive region (343) formed at an edge in the upper direction (e.g., in the +Y-axis direction) and having a greater adhesive force (e.g., an adhesive force of approximately 0.8 Kgf to 1.2 Kgf) than the main cover portion (310).

[0154] According to one embodiment, a portion of an edge (e.g., a third adhesive region (343)) in the upper direction (e.g., in the +Y-axis direction) of the third cover portion (340) may have an inclined shape (S3). For example, with respect to the upper edge (e.g., an edge in the +Y-axis direction) of the third cover portion (340) extending from the main cover portion (310), corners on both sides (left and right) may include a shape inclined at a specified angle. For example, the third cover portion (340) may have a rectangular shape (e.g., a square or rectangle) extending in the upper direction (e.g., in the +Y-axis direction) from the main cover portion (310), and corners on both sides may have a partially fine shape (e.g., a cut, concave, or stepped) shape.

[0155] According to one embodiment, when the third adhesive region (343) is adhered to the fourth cover portion (350), the third adhesive region (343) may be adhered closer and more widely to the center of the fourth cover portion (350) without overlapping the first adhesive region (323) and the second adhesive region (333) according to the inclined shapes (S3) of the both edges of the third cover portion (340). When the first adhesive region (323), the second adhesive region (333) and the third adhesive region (343) are adhered, the first adhesive region (323), the second adhesive region (333) and the third adhesive region (343) may be spaced apart from each other. The facing inclined edges of the first adhesive region (323) and the third adhesive region (343) may be arranged in parallel. The facing inclined edges of the second adhesive region (333) and the third adhesive region (343) may be arranged in parallel.
