The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

With the continuous progress of technology, steel-shell batteries are increasingly used in electronic devices. It is understood that a steel-shell battery is a battery with a steel shell, and is advantageous in terms of safety, temperature resistance and life compared to a conventional aluminum-shell battery. Meanwhile, the steel shell has the characteristics of corrosion resistance, strong compression resistance, good sealing performance and the like, so that the problems of leakage of electrolyte, gas leakage and the like can be effectively prevented.
As shown in fig. 1 to 4, the battery includes a battery cell 11 having a casing 12, the casing 12 includes a cover plate 122 and a casing 121 having an opening at one side, the cover plate 122 is covered on the opening side of the casing 121, and in order to facilitate welding while avoiding damage to the battery cell 11, the area of the cover plate 122 needs to be larger than the cross-sectional area of the casing 121, so that, after the cover plate 122 is connected with the casing 121, the cover plate 122 forms a flange 123 at the peripheral edge of the casing 121.
With the development of 5G technology, the functions and usage scenarios of electronic devices such as mobile phones and tablet computers are becoming more and more abundant, and the battery capacity of the electronic devices is also increasing. Accordingly, the related art expands the overall capacity of the battery by providing a dual cell battery. Illustratively, two steel can batteries are spliced to form a double cell battery. The existence of the flange edge 123 on the housing 12 of the battery cell 11 may cause a certain space loss, for example, the flange edge 123 on the housing 121 abuts against the flange edge 123 of the adjacent other battery cell 11, resulting in a larger space between the two battery cells 11, thereby causing a certain space loss, which is not beneficial to the miniaturization design of the electronic device.
In order to solve the technical problem, the present disclosure provides a battery assembly, along the thickness direction of an electric core, cover plates of two adjacent electric cores are located at different sides of the electric core, an avoidance structure is arranged in a region corresponding to a flange edge of the adjacent electric core on a shell of each electric core, the flange edge of the adjacent electric core near to the electric core in each electric core stretches into an avoidance space formed by the avoidance structure of the adjacent electric core, and the distance between the two adjacent electric cores is reduced. By the design, space loss caused by the flange edge of the adjacent battery cell can be absorbed, so that the miniaturization design of the electronic equipment is facilitated, the improvement of the whole capacity of the battery is facilitated, and the use experience of a user is improved.
An exemplary embodiment of the present disclosure provides a battery assembly, as shown in fig. 9, where the battery assembly 1 includes at least two electric cells 11 disposed side by side, and for example, the battery assembly 1 may include two electric cells 11 disposed side by side, or may include three or more electric cells 11 disposed side by side. As shown in fig. 5 to 8, each of the battery cells 11 includes a case 12, the case 12 including a cover plate 122 and a case 121 having one side opened, the cover plate 122 being provided to cover the opened side of the case 121 and forming a flange portion 123 at the outer periphery of the opened portion of the case 121. Illustratively, the orthographic projection of the housing 121 onto the cover 122 is located within the cover 122, e.g., the housing 121 is of rectangular configuration, the cover 122 is also of rectangular configuration, and each rim of the cover 122 forms a flange edge 123 on the rim of its corresponding housing 121.
As shown in fig. 9 to 12, the cover plates 122 of two adjacent cells 11 are located on different sides of the cell 11 in the thickness direction of the cell 11, and when the battery assembly 1 includes two cells 11, i.e., a first cell and a second cell, which are arranged side by side, the plane of the cover plate 122 of the first cell is opposite to, but not coincident with, the plane of the cover plate 122 of the second cell. When the battery assembly 1 includes three electric cells 11 arranged side by side, namely, a first electric cell, a second electric cell and a third electric cell, a plane where the cover plate 122 of the first electric cell is located is the same plane or parallel to a plane where the cover plate 122 of the third electric cell is located, and a plane where the cover plate 122 of the first electric cell is located is opposite to a plane where the cover plate 122 of the second electric cell is located. By analogy, when the battery assembly 1 is provided with a plurality of cells 11 side by side, the planes of the cover plates 122 of each adjacent two of the cells 11 are opposite.
The housing 121 of each cell 11 is provided with a relief structure 13 in a region corresponding to the flange edge 123 of the adjacent cell 11, and a relief space formed by the relief structure 13 is used for inserting the flange edge 123 of the adjacent cell 11. Illustratively, the avoidance structure 13 may be, for example, an inclined plane or a step structure, so long as the flange edge 123 of each cell 11 close to the adjacent cell 11 is inserted into the avoidance space formed by the avoidance structure 13 of the adjacent cell 11, and the specific arrangement form of the avoidance structure 13 is not specifically limited.
Taking the battery assembly 1 as an example and comprising two electric cores 11 arranged side by side, the two electric cores 11 comprise a first electric core and a second electric core, an avoidance structure 13 is arranged in a region corresponding to a flange edge 123 of the second electric core on a shell 121 of the first electric core, an avoidance structure 13 is also arranged in a region corresponding to the flange edge 123 of the first electric core on the shell 121 of the second electric core, after the first electric core and the second electric core are spliced, the flange edge 123 of the first electric core facing the second electric core side is inserted into an avoidance space formed by the avoidance structure 13 of the second electric core, and the flange edge 123 of the second electric core facing the first electric core side on the other side is inserted into an avoidance space formed by the avoidance structure 13 of the first electric core. Therefore, the distance between the first battery cell and the second battery cell is shortened, namely, one side surface of the first battery cell facing the second battery cell is close to or attached to one side surface of the second battery cell facing the first battery cell.
By adopting the arrangement mode, the space loss caused by the flange edge 123 of the adjacent battery cell 11 can be absorbed, so that the miniaturization design of the electronic equipment is facilitated, the improvement of the whole capacity of the battery is facilitated, and the use experience of a user is further improved.
As shown in fig. 5 and 11, in an embodiment, the housing 121 of each cell 11 includes a first surface 1211, a first step surface 131, a second step surface 132, and a second surface 1212 that are sequentially connected, where the first surface 1211 and the second step surface 132 face the housing 121 of the adjacent cell 11, and the first step surface 131 and the second surface 1212 face away from the second surface 1212 of the cover plate 122, and along the arrangement direction of at least two cells 11, the first surface 1211 protrudes away from the second surface 1212.
The first step surface 131 and the second step surface 132 connected to each other constitute the relief structure 13. By the design, the avoiding structure 13 is simple in arrangement, convenient to process and convenient to control in size, and effective avoiding of the flange edge 123 is achieved. The avoidance structure 13 formed by the first step surface 131 and the second step surface 132 forms an avoidance space, and after the flange edge 123 of each cell 11, which is close to the adjacent cell 11, extends into the avoidance space on the adjacent cell 11, the flange edge 123 is opposite to the first step surface 131 of the adjacent cell 11. By adopting the arrangement mode, the first step surface 131 compensates the width of the flange edge 123 of the adjacent battery cell 11 so as to realize the effect of absorbing the space loss caused by the flange edge 123, thereby being beneficial to the miniaturization design of the electronic equipment, being beneficial to the improvement of the whole capacity of the battery and further improving the use experience of a user.
With continued reference to fig. 5 and 11, in one embodiment, after the flange edge 123 of each cell 11, which is close to the adjacent cell 11, extends into the avoidance space formed by the avoidance structure 13 on the adjacent cell 11, the flange edge 123 abuts against the second step surface 132 of the adjacent cell 11. By such design, on the one hand, the structure of the battery assembly 1 is more compact, and the space loss caused by the flange edge 123 is further reduced. On the other hand, it is also possible to prevent impurities from entering the escape space due to the clearance generated between the flange edge 123 and the second step surface 132 of the adjacent cell 11.
In another embodiment, after the flange edge 123 of each cell 11 near the adjacent cell 11 extends into the avoiding space formed by the avoiding structure 13 on the adjacent cell 11, the flange edge 123 and the second step surface 132 of the adjacent cell 11 have a preset gap. The preset gap may be, for example, 1mm to 3mm. By the design, a safe distance is provided for assembly between two adjacent battery cells 11, and damage such as stabbing of the battery cells 11 caused by flange edge 123 on the adjacent battery cells 11 can be effectively avoided, so that reliability of the battery assembly 1 is improved. On the other hand, the situation that the first surfaces 1211 of the shells 121 of two adjacent two battery cells 11 cannot be abutted due to the fact that the width of the flange edge 123 on the adjacent battery cells 11 is too large can be effectively avoided, so that the distance between the two battery cells 11 is further shortened, the structure of the battery assembly 1 is more compact, and occupation of the internal space of the electronic equipment is further reduced.
With continued reference to fig. 5 and 11, in an embodiment, the first surfaces 1211 of the housings 121 of two adjacent battery cells 11 are abutted, and with such arrangement, the space between the housings 121 of two battery cells 11 is further reduced, so that on one hand, the structure of the battery assembly 1 is more compact, the occupation of the battery assembly 1 to the internal space of the electronic device is reduced, thereby being beneficial to the miniaturization design of the electronic device, and on the other hand, the internal volume of the housing 12 of each battery cell 11 can be further enlarged, thereby being beneficial to the improvement of the overall capacity of the battery, and improving the use experience of the user.
In one embodiment, the housing 12 is a steel structural member. In this way, on the one hand, the steel structural member is more advantageous in terms of safety, temperature resistance and life, compared to the aluminum material, so that the reliability of the battery assembly 1 can be effectively improved. On the other hand, the steel shell has the characteristics of corrosion resistance, strong compression resistance, good sealing performance and the like, so that the problems of leakage of electrolyte, gas leakage and the like can be effectively prevented, and the reliability of the battery assembly 1 is further improved.
As shown in fig. 13, in an embodiment, the battery assembly 1 includes a protection circuit board 14, the protection circuit board 14 is disposed on the same side of each of the battery cells 11, and the protection circuit board 14 is electrically connected to each of the battery cells 11. The battery assembly 1 protects each of the battery cells 11 by using an integrated protection circuit board 14, for example, the battery assembly 1 includes two battery cells 11 arranged side by side, the two battery cells 11 form a battery cell group, the protection circuit board 14 is arranged on the top of the battery cell group, and two ends of the protection circuit board 14 extend to the two battery cells 11 respectively, so that the protection circuit board 14 can be electrically connected with the two battery cells 11. Compared with the mode that the protection circuit boards 14 are arranged on the battery cells 11 respectively, the integrated protection circuit boards 14 are adopted to protect the battery cells 11, so that the use of the protection circuit boards 14 is saved, the battery assembly 1 is simple in structure, the weight of the battery assembly 1 can be reduced, the lightweight design of electronic equipment is facilitated, meanwhile, the assembly efficiency of the battery assembly 1 can be effectively improved, and the production efficiency of the electronic equipment is improved.

The negative electrode connection portions 112 are electrically connected to the housing 12 of the battery cell 11 where the negative electrode connection portions 112 are located, and for example, the negative electrode connection portions 112 are welded to the housing 12 of the battery cell 11 where the negative electrode connection portions 112 are located because the housing 12 of the battery cell 11 is made of a steel structural member, so that the conductive connection between the negative electrode connection portions 112 and the housing 12 of the battery cell 11 where the negative electrode connection portions 112 are located is achieved.
Meanwhile, the first surfaces 1211 of the housings 121 of the adjacent two electric cores 11 abut against each other, and illustratively, the outer shell 12 of each electric core 11 is made of a steel structural member, and the first surfaces 1211 of the housings 121 of the adjacent two electric cores 11 are welded, so that conductive connection between the outer shells 12 of the adjacent two electric cores 11 is realized, and thus, the outer shells 12 of the electric cores 11 simultaneously have negative charges.
