At least one end (e.g. at least one of both opposing vertical ends of the adhesive layer 241 having a rectangular structure) among ends (e.g., four edges when the adhesive layer 241 is rectangular) of the adhesive layer 241 adhered to the outer surface of the battery 242 (e.g., outer face of each of pouches 305a and 305b) may be aligned with one corresponding end of the roll fixing tape 302. When one end of the roll fixing tape 302 and one end of the adhesive layer 241 are aligned with each other, even though the jelly-roll 301 flows inside the pouches 305a and 305b by an external pressure, the alignment structure of the roll fixing tape 302 and the adhesive layer 241 may uniformly disperse the external pressure to minimize damage to the pouches 305a and 305b. In this regard, the roll fixing tape 302 may be disposed between the jelly-roll 301 and an inner wall of each of the pouches 305a, 305b, and may be adhered to an inner region of each of the pouches 305a, 305b.

The substrate layer 302b is a component for securing a moldability of the roll fixing tape 302, and may be formed of, for example, a nylon, a PET, or the like. The substrate layer 302b may be disposed to secure an insulation of the roll fixing tape 302 when the battery is constructed. The DL layer 302-3 may be disposed to maintain a lamination strength between the substrate layer 302b and the barrier layer 302a when shaping the roll fixing tape 302. The DL layer 302-3 may have heat and moisture resistant properties. The first treatment layer 302-1 and the second treatment layer 302-2 may be disposed for preventing a deterioration of an adhesion due to an electrolytic solution of the battery (HF resistance). The barrier layer 302a may be applied to improve the formability of the roll fixing tape 302. In addition, the barrier layer 302a may be applied to maintain an airtightness of the roll fixing tape 302, and to maintain a steam barrier property. The adhesive layer 302-4 may be applied to maintain the steam barrier property. The adhesive layer 302-4 may provide an adhesion to the barrier layer 302a and the sealant layer 302c. The adhesive layer 302-4 may have heat resistance and insulation properties. The sealant layer 302c may be applied to maintain a strength of a sealing. The sealant layer 302c may have heat resistance and insulation properties.

The first adhesive layer 441 may secure the battery 442 to the receiving space 423 of the first case 420. The first adhesive layer 441 may have the same shape and size as the roll fixing tape 402. Alternatively, a height (e.g., a length in a longitudinal direction (or a third direction)) of the first adhesive layer 441 may be the same as a height (e.g., a length in the longitudinal direction (or the third direction)) of the roll fixing tape 402. An attachment position of the first adhesive layer 441 on the battery 442 may include a position in which while at least one of top and bottom ends of the first adhesive layer 441 is aligned with at least one of top and bottom ends of the first adhesive layer 441, the first adhesive layer 441 and the roll fixing tape 402 are overlapped with each other in a up and down direction (e.g. in the first direction or in the second direction).

The second adhesive layer 443 may be attached to the face of the battery 442 facing the second direction side. Alternatively, the second adhesive layer 443 may be disposed between the face of the battery 442 facing the second direction side and the bracket 460. The second adhesive layer 443 may be provided in various shapes similar to the first adhesive layer 441, for example. According to an embodiment, the second adhesive layer 443 may be provided in a shape of a polygonal band (e.g., a rectangular band) having a hollow center (or having a first hole 443A in a predetermined size at the center). A size and an edge shape of the second adhesive layer 443 may be the same as the roll fixing tape 402 disposed on an inner region the battery 442 (or inner region of a pouch of the battery 442). Alternatively, a length in a longitudinal direction (or a third direction) of the second adhesive layer 443 may be the same as a length in a longitudinal direction (or the third direction) of the roll fixing tape 402.

The bracket 460 may be disposed between the first case 420 and the second case 450 to cover a periphery of the battery 442 and fix the battery 442. For example, when the battery 442 is received in the receiving space 423 of the first case 420, the bracket 460 may be disposed so as to cover the face of the battery 442 facing the second direction side, and fix the battery 442 based on the second adhesive layer 443. According to various embodiments, the bracket 460 may be secured to the receiving space 423 of the first case 420 where the battery 442 is received therein. The bracket 460 may have a hollow center (e.g., having a second hole 460A of a predetermined size). A size of the second hole 460A may be smaller than a size of the first hole 443A. The bracket 460 may be at least partially made of a metal material so as to have a predetermined stiffness. Alternatively, the bracket 460 may be provided as a plastic structure. A face of the bracket 460 facing the second direction side may face a face of the second case 450 facing the first direction side, and may be fixed to the face of the second case 450 facing the first direction side.

In the following description, adhesive layers 541 and 543 are disposed on a first face 500a and a second face 500b of a battery 542, respectively. However, the disclosure is not limited thereto. For example, the battery structure of the disclosure may include only the battery 542 and the first adhesive layer 541, or only the battery 542 and the second adhesive layer 543.

With reference to FIG. 5, based on a normal state 501, an electronic device 500 may include housings 520, 550 (or casings, or plates). Further, the housings 520, 550 may include a first structure 520 toward the first face 500a (or the first support member 211 and the side bezel structure 220, or the first case, or the front case described in FIG. 2) and a second structure 550 (the first structure and the second structure can be any planar structure made of material such as glass, polymer, metal, or a combination thereof) toward the second face 500b opposite to the first face 500a (or the second support member 250, or second case, or the rear face case). Alternatively, the second structure 550 may form at least a part of the housing.

The polymer layer 502 may be disposed between the pouch 515 and the first outer surface 511 when viewed on the first outer surface 511. According to various embodiments, when viewed on the first outer surface 511, the polymer layer 502 may be disposed at least one of between the pouch 515 and the first outer surface 511, between the pouch 515 and the second outer surface 512, between the pouch 515 and the third outer surface 513, or between the pouch 515 and the fourth outer surface 514.

The first adhesive layer 541 among the battery and adhesive layers 541, 542, and 543 may be disposed between the pouch 515 and the first face 500a to adhere the outer surface of the pouch 515 to an inner wall of the first structure 520. The first adhesive layer 541 may include a first edge 541_1 extending from a center of the first face 500a toward the third outer surface 513, and a second edge 541_2 extending from the center of the first face 500a toward the fourth outer surface 514.

The second adhesive layer 543 among the battery and adhesive layers 541, 542, 543 may be disposed between the pouch 515 and the second face. The second adhesive layer 543 may include a third edge 543_1 extending from a center of the second face 500b toward the third outer surface 513, and a fourth edge 543_2 extending from the center of the second face 500b toward the fourth outer surface 514. According to various embodiments, the first edge 541_1 and the third edge 543_1 may be substantially aligned with each other when viewed from the first outer surface 511. Alternatively, a top end part of the first edge 541_1 and a top end part of the third edge 543_1 may have the same height with respect to a center of the jelly-roll 549 when viewed from the third outer surface 513. The second edge 541_2 and the fourth edge 543_2 may be substantially aligned with each other when viewed from the first outer surface 511. Alternatively, a bottom end part of the second edge 541_2 and a bottom end part of the fourth edge 543_2 may have the same height with respect to a center of the jelly-roll 549 when viewed from the fourth outer surface 514.

According to various embodiments, the polymer layer 502 may include a fifth edge 502_1 parallel to the first outer surface 511 and extending in the direction of the third outer surface 513, and a sixth edge 502_2 parallel to the first outer surface 511 and extending in the direction of the fourth outer surface 514. The first edge 541_1 and the fifth edge 502_1 may be substantially aligned with each other when viewed from the first outer surface 511. Alternatively, the top end part of the first edge 541_1 and a top end part of the fifth edge 502_1 may have the same height with respect to the center of the jelly-roll 549 when viewed from the third outer surface 513 direction. The second edge 541_2 and the sixth edge 502_2 may be substantially aligned with each other when viewed from the first outer surface 511. Alternatively, the bottom end part of the second edge 541_2 and a bottom end part of the sixth edge 502_2 may have the same height with respect to the center of the jelly-roll 549 when viewed from the direction of the fourth outer surface 514.

According to various embodiments, the first structure 520 may include at least a portion of a metal material. At least a portion of the second structure 550 may include glass.

According to various embodiments, when outer edges of the electronic device 500 collide with the ground, a certain object, or the like due to a falling of the electronic device 500, the jelly-roll 549 may be deformed as in a falling state 503. For example, as shown, a central portion of the jelly-roll 549 may be displaced in the fourth direction, and the central portion in the fourth direction of the jelly-roll 549 and the pouch 515 may be deformed 590 to protrude in the fourth direction. According to various embodiments, corresponding to the deformation 590 of one region of the jelly-roll 549 (e.g., the fourth outer surface 514), the other region thereof (e.g., the third outer surface 513) may also be deformed.

As the first adhesive layer 541 and the second adhesive layer 543 coincide with the end parts of the polymer layer 502 (or the roll fixing tape of FIG. 3) while securing the pouch 515 to the first structure 520 and the second structure 550, even though the jelly-roll 549 and the pouch 515 protrude by a predetermined amount in the fourth direction, a stress acting in the fourth direction may be evenly dispersed to prevent the battery 542 from being damaged. Alternatively, a difference in adhesion between a region where the first adhesive layer 541 and the second adhesive layer 543 are attached to the pouch 515 and a region where the polymer layer 502 is attached to an inner wall of the pouch 515 is removed, the battery 542 (and adhesive layers 541, 543) of the disclosure or the electronic device including the battery 542 (and adhesive layers 541, 543) may evenly distribute the stress acting on the deformation of the jelly-roll 549 even though at least a portion of the jelly-roll 549 moves in the fourth direction.

In the above description, the upper and lower portions of the first adhesive layer 541 (e.g. the first edge 541_1 and the second edge 541_2) are aligned with the upper and lower portions of the polymer layer 502 (e.g. the fifth edge 502_1 and the sixth edge 502_2) (heights of the end parts of the respective edges are the same or similar (located within a certain error range) with respect to one face of the pouch 515), but the disclosure is not limited thereto. For example, only the second edge 541_2 of the first adhesive layer 541 may be aligned with the sixth edge 502_2 of the polymer layer 502 (heights spaced upward from the bottom end (e.g., the fourth outer surface 514) of the pouch 515 are the same), and the first edge 541_1 and the fifth edge 502_1 may not be aligned therewith. For example, a height from the top end (e.g., third outer surface 513) of the pouch 515 to the first edge 541_1 and a height from the top end of the pouch 515 to the fifth edge 502_1 may be different from each other. According to various embodiments, only the fourth edge 543_2 of the second adhesive layer 543 and the sixth edge 502_2 of the polymer layer 502 may be aligned with each other, and the third edge 543_1 of the second adhesive layer 543 and the fifth edge 502_1 of the polymer layer 502 may not be aligned with each other. Alternatively, according to various embodiments, the first edge 541_1 of the first adhesive layer 541, the third edge 543_1 of the second adhesive layer 543, and the fifth edge 502_1 of the polymer layer 502 may be located on a same horizontal plane with respect to the top end (e.g., the third outer surface 513) of the pouch 515. At least one of a height from the bottom end (e.g., the fourth outer surface 514) of the pouch 515 to the second edge 541_2 of the first adhesive layer 541, a height from the bottom end of the pouch 515 to the fourth edge 543_2 of the second adhesive layer 543, and a height from the bottom end of the pouch 515 to the sixth edge 502_2 of the polymer layer 502 may be different from the rest.

According to various embodiments, heights of the fourth outer surface 514 of the jelly-roll 549 and the second edge 541_2 of the first adhesive layer 541 (or the fourth edge 543_2 of the second adhesive layer 543 and the sixth edge 502_2 of the polymer layer 502) are different from each other. Thus, when an external pressure is generated, a maximum pressure point is moved to the second edge 541_2 of the first adhesive layer 541 (or the fourth edge 543_2 of the second adhesive layer 543, the sixth edge 502_2 of the polymer layer 502). Therefore, the battery and adhesive layers 541, 542, 543 of the disclosure may minimize an occurrence of wrinkles or an internal deformation due to a flow of the jelly-roll 549. In addition, the battery and adhesive layers 541, 542, and 543 of the disclosure may distribute a pressure due to an external impact as the first adhesive layer 541 and the second adhesive layer 543 align with the polymer layer 502.

According to various embodiments described above, the electronic device 500 according to the embodiment includes the housings 520 and 550, the first structure 520 disposed in the housing, wherein the first structure 520 includes the first face 500a; the second structure 550 disposed in the housing or disposed in a portion of the housing, wherein the second structure 550 includes the second face 500b opposite to the first face, and the battery and adhesive layers 541, 542, and 543 disposed between the first face and the second face, wherein the battery and adhesive layers 541, 542, and 543 includes the jelly-roll 549 including a positive electrode substrate, a separator, and a negative electrode substrate wrapped around the rectangular face, wherein the jelly-roll includes the first outer surface 511 parallel to the rectangular plane and facing in the first direction, the second outer surface 512 facing in the second direction opposite to the first direction, the third outer surface 513 facing in a third direction perpendicular to the first and second directions and to the rectangular face, wherein the third outer surface connects the first outer surface and the second outer surface, and the fourth outer surface 514 facing in a fourth direction opposite to the third direction, wherein the fourth outer surface connects the first outer surface and the second outer surface, wherein the battery structure includes a pouch containing the jelly-roll, wherein the battery and adhesive layers 541, 542, and 543 includes a polymer layer 502 including stretched polystyrene, wherein the polymer layer is disposed between the pouch and the first outer surface or the second outer surface and/or between the third outer surface and the fourth outer surface when viewed from the first outer surface, wherein the first adhesive layer 541 is disposed between and contacting the pouch and the first face, wherein the first adhesive layer includes a first edge extending in parallel with the third outer surface and a second edge extending in parallel with the fourth outer surface when viewed from the first outer surface, and a second adhesive layer 543 disposed between and contacting the pouch and the second face, wherein the second adhesive layer includes a third edge extending in parallel with the third outer surface and a fourth edge extending in parallel with the fourth outer surface when viewed from the first outer surface, wherein the first edge and the third edge are substantially aligned with each other when viewed from the first outer surface, and wherein the second edge and the fourth edge are substantially aligned with each other when viewed from the first outer surface.
