[0040] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0041] Please refer to Figures 1 to 6In some embodiments, the battery includes: a shell 100 and a battery cell (not shown). The shell 100 has a receiving cavity, and the outer surface of the shell 100 includes two first walls 110 and two second walls 120, the two first walls 110 are arranged opposite to each other, the two second walls 120 are arranged opposite to each other, the two ends of the first wall 110 are respectively connected to the two second walls 120, the area of ​​the second wall 120 is larger than the area of ​​the first wall 110, wherein at least one first wall 110 is arranged as an arc-shaped wall. The battery cell is arranged in the receiving cavity, and the projection of the battery cell overlaps with the projection of the second wall 120 along the thickness direction of the battery cell. Specifically, the first wall 110 of the receiving cavity of the shell 100 is arranged as an arc-shaped wall, and after the battery cell is arranged in the receiving cavity, the projection of the battery cell overlaps with the projection of the second wall 120 in the thickness direction of the battery cell, that is, the shape of the battery cell can be consistent with the shape of the second wall 120, and an arc-shaped structure is arranged on the battery cell. In the prior art, the battery is square in shape, and the adaptability of square batteries is low. However, the battery of the present application has an arc structure, and the adaptability of the battery of the present application is better. The arc structure can accommodate more battery cells, so that the electronic device has a better endurance. Specifically, the battery has a good matching degree, so that it can effectively match the electronic device, so that the electronic device has a better endurance. Among them, the battery of the present application can be adapted to electronic devices such as wristbands.

[0042] Among them, in the above-mentioned housing 100, in addition to the first wall 110 being set as an arc-shaped wall, the second wall 120 can be a planar structure. When the housing 100 is placed flat on a horizontal plane, the second wall 120 is parallel to the horizontal plane, and the first wall 110 can be parallel to the vertical direction. Among them, the area of ​​the second wall 120 is greater than the area of ​​the first wall 110, which can be specifically that the length of the second wall 120 is equal to the length of the first wall 110, but the width of the second wall 120 is greater than the length of the first wall 110.

[0043] Refer to the following Figure 1 and Figure 2 , compare the battery of the present application with the square battery in the prior art, Figure 2 It is a square battery in the prior art. Figure 1 For the battery in this application, it can be seen that when the lengths of the two are the same, the design of the arc-shaped wall in the battery of this application can further increase the width of the battery, thereby having a higher energy density. And while increasing the width, the volume of the battery will not increase too much, so that the battery occupies too much space. In addition, the setting of the arc-shaped wall can make the battery housing 100 have a groove, and the design of the groove can avoid the electronic device when the battery is placed in the electronic device, wherein the groove can avoid the speaker in the electronic device (the speaker is cylindrical), so that the electronic device has better endurance and smaller volume.

[0044] The battery cell is introduced below. In some embodiments, the battery cell is formed by stacking pole pieces, and the pole pieces are formed by cutting. Specifically, the battery cell is formed by stacking a positive pole piece, a separator and a negative pole piece using a stacking process. The battery cell is a stacked-type battery cell, and the battery cell includes a plurality of pole pieces stacked on each other, and the plurality of pole pieces are stacked along the thickness direction, and the shape of the pole piece is the same as the shape of the second wall 120. Among them, since the first wall 110 of the shell 100 is an arc-shaped wall, therefore, when manufacturing the pole piece, the pole piece can be cut into an arc shape so that the shape of the pole piece is adapted to the second wall 120. The method of cutting the pole piece can improve the manufacturing efficiency of the battery cell. Furthermore, when the pole pieces are stacked, the stacking direction is the thickness direction of the pole piece.

[0045] It is mentioned above that at least one first wall 110 is configured as an arcuate wall, wherein at least one first wall 110 is configured as an arcuate wall in various embodiments, which will be described in detail below. Figure 5 In some embodiments, one first wall 110 is configured as an arcuate wall, the other first wall 110 and the second wall 120 are both configured as planes, and the arcuate wall is configured to be concave in the direction close to the other first wall 110. Specifically, after the arcuate wall is concave, the battery can form an escape groove 150, and the escape groove 150 can avoid other components in the electronic device. Please refer to Figure 7 In addition, in addition to the concave setting of the arc wall, the arc wall can also be convexly set in a direction away from the other first wall 110. When the arc wall is convexly set, a evasive effect can be formed at the connection between the third wall 130 and the first wall 110, allowing the battery to evade other components.

[0046] Furthermore, in addition to the method in which one first wall 110 is configured as an arc-shaped wall, the two first walls 110 may also be configured as arc-shaped walls. Figure 8 In some embodiments, the second wall 120 is set as a plane, and the two first walls 110 are both set as arc-shaped walls, and the two arc-shaped walls are concave, and the concave directions of the two arc-shaped walls are opposite. Among them, the two first walls 110 are set as arc-shaped walls. On the one hand, the battery has a higher energy density. On the other hand, the two arc-shaped walls can form two avoidance grooves 150, thereby avoiding space and facilitating the layout of other components. Please refer to Fig. 9 In addition, the arc-shaped wall can be convex in addition to the concave setting. When the arc-shaped wall is convex, a yielding effect can be formed at the connection between the third wall 130 and the first wall 110, so that the battery can yield to other components.

[0047] Furthermore, there are two situations for the arc-shaped wall, one situation is that the arc-shaped wall is bent once, and the other situation is that the arc-shaped wall is bent multiple times. Fig.10In some embodiments, the other first wall 110 and the second wall 120 are both set to be planes, and one first wall 110 is set to be an arcuate wall, and the arcuate wall is bent multiple times along the length direction of the second wall 120. For example, the arcuate wall can be bent twice along the length direction of the second wall 120, so that the arcuate wall forms an "S" shape. The number of times the arcuate wall is bent is not specifically limited. Among them, after the arcuate wall is bent multiple times, multiple avoidance grooves 150 can be formed, so as to facilitate avoidance for other components.

[0048] Furthermore, in addition to the first wall 110 being configured as an arcuate wall, the arcuate wall being bent multiple times along the length direction of the second wall 120, the two first walls 110 may also be configured as arcuate walls, the arcuate walls being bent multiple times along the length direction of the battery. Fig.11 In some embodiments, the second wall 120 is set as a plane, and the two first walls 110 are both set as arc walls, and the arc walls are bent multiple times along the length direction of the battery. The two arc walls can be bent twice respectively to form an "S" shape. The number of times the arc wall is bent is not specifically limited. Among them, after the arc wall is bent multiple times, multiple avoidance grooves 150 can be formed, so as to facilitate avoidance of other components.

[0049] Further, in some embodiments, the thickness of the shell 100 is L1, 0.05mm≤L1≤0.3mm. When the thickness of the shell 100 is greater than 0.3mm, the larger thickness of the shell 100 will cause the battery to occupy too much space. When the thickness of the shell 100 is less than 0.05mm, the thinner thickness of the shell 100 will cause the strength of the shell 100 to not meet the requirements, making the reliability of the battery lower. Among them, the thickness of the shell 100 specifically refers to the wall thickness of the first wall 110, or the wall thickness of the second wall 120 or the wall thickness of the third wall 130, or the wall thickness of the fourth wall 140.

[0050] For further information, please refer to Figures 1 to 6In some embodiments, the outer surface of the housing 100 further includes a third wall 130 and a fourth wall 140 that are arranged opposite to each other, and the two ends of the second wall 120 are respectively connected to the third wall 130 and the fourth wall 140, and the two first walls 110, one second wall 120, the third wall 130 and the fourth wall 140 together form a receiving cavity, and the other second wall 120 is welded to the first wall 110, the third wall 130 and the fourth wall 140 to close the opening of the receiving cavity. Specifically, before the battery cell is placed in the receiving cavity, the two first walls 110, one second wall 120, the third wall 130 and the fourth wall 140 can be welded to form a receiving cavity, and then the battery cell is placed in the receiving cavity, and finally the second wall 120 is welded to close the receiving cavity. Among them, a liquid injection hole 200 can be set on the third wall 130 to facilitate the subsequent injection of electrolyte into the receiving cavity. Meanwhile, a pole hole may be provided on the third wall 130 , and a pole 300 may be provided in the pole hole, and the pole 300 is used to be electrically connected to the positive and negative electrodes of the battery cell. In addition, the areas of the third wall 130 and the fourth wall 140 are both smaller than the area of ​​the second wall 120 .

[0051] Furthermore, the material of the housing 100 may be a metal material, wherein the housing 100 made of a metal material can provide higher safety, thereby protecting the battery cell. In addition, after the housing 100 is changed to a metal material, the workpiece can be made into the housing 100 by welding, so that the sealing of the housing 100 is better. Therefore, in some embodiments, the material of the housing 100 is one of carbon steel, aluminum alloy, copper alloy, pottery alloy, zinc alloy, ductile iron, manganese steel, stainless steel, brass, bronze, white copper, solder, and duralumin.

[0052] In some embodiments, the electronic device includes: a main body and the battery in the above-mentioned embodiment. The main body has a battery compartment. The battery is disposed in the battery compartment. Specifically, the first wall 110 of the accommodating cavity of the shell 100 is configured as an arc-shaped wall, and after the battery cell is disposed in the accommodating cavity, the shape of the battery cell can be consistent with the shape of the second wall 120, and an arc-shaped structure is provided on the battery cell. In the prior art, the shape of the battery is square, so the adaptability is low, while the battery of the present application has an arc-shaped structure, so it has better adaptability, and the arc-shaped structure can accommodate more battery cells, so that the endurance of the electronic device is better. Furthermore, the endurance of the electronic device with the battery is better.

[0053] In some embodiments, the battery compartment includes a fifth wall, and the fifth wall is matched with the first wall 110. Specifically, when the first wall 110 is concave, the fifth wall can be convex, so as to be matched with the first wall 110. When the first wall 110 is convex, the fifth wall can be concave, so as to be matched with the first wall 110. After the fifth wall is matched with the first wall 110, the battery can make full use of the space of the electronic device, so that the electronic device can still have good endurance in a compact volume.

[0054] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
