[0002] With the development of science and technology, batteries are used more and more widely. For example, they are widely used in various mobile terminals. Usually, dual-cell batteries are used in mobile terminal devices. In the production process of dual-cell batteries, the two cells are mainly set up, and then the pole ears connected to the top seals of the two cells are connected to the circuit board, and then the circuit board and the top seal are encapsulated by injection molding. In order for the battery to be connected to the component to be powered, a flexible circuit board is usually connected to the circuit board, and a groove is set on the surface of the injection molding away from the cell. The flexible circuit board is partially bent and located in the groove. However, in this design, the depth of the groove cannot guarantee the accommodation of the bent part of the flexible circuit board due to the limited thickness of the injection molding glue on the top of the battery. In order to accommodate the bent part of the flexible circuit board, the size of the injection molding can only be increased. Therefore, under the premise of keeping the overall size of the battery unchanged, the effective space that can be provided to the cell is reduced, and the energy density of the battery is low, resulting in a decrease in the capacity of the battery.

[0038] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] like Figures 1 to 9 As shown, the battery includes: at least two battery cell bodies 10 arranged in parallel, the battery cell body 10 has a top surface 101, a bent top sealing edge 11 is arranged on the top surface 101, and the top sealing edge 11 is connected to the pole ear 12; a protective plate 20, the protective plate 20 and the top sealing edge 11 are stacked and distributed, and the top sealing edge 11 is located between the protective plate 20 and the top surface 101, the pole ear 12 is electrically connected to the protective plate 20, and a gold finger 30 is arranged on the surface of the protective plate 20 away from the top surface 101; an injection molded part 40, the injection molded part 40 encapsulates the protective plate 20 and the top sealing edge 11, and an avoidance hole 401 is arranged on the injection molded part 40, the avoidance hole 401 is opposite to the gold finger 30, and the avoidance hole 401 avoids the gold finger 30 so that the gold finger 30 can be connected to the part to be connected.

[0040] In the embodiment of the present application, since the battery cell body 10 has a top surface 101, a bent top seal 11 is provided on the top surface 101, the top seal 11 is connected to the pole ear 12, the protective plate 20 and the top seal 11 are stacked and distributed, and the top seal 11 is located between the protective plate 20 and the top surface 101, and the pole ear 12 is electrically connected to the protective plate 20, therefore, the protective plate 20 can protect the interior of the battery cell body 10 through the pole ear 12. Since the protective plate 20 is provided with a gold finger 30 on the surface facing away from the top surface 101, and the injection molded part 40 encapsulates the protective plate 20 and the top sealing edge 11, when encapsulating the battery, the protective plate 20 and the sealing edge can be encapsulated by the injection molded part 40, and an avoidance hole 401 is provided on the injection molded part 40, and the avoidance hole 401 is opposite to the gold finger 30, so that the avoidance hole 401 can avoid the gold finger 30, and does not affect the connection between the gold finger 30 and the part to be connected. In addition, the protective plate 20 is connected to the part to be connected through the gold finger 30, and the flexible circuit board on the protective plate 20 is cancelled. That is, it is equivalent to replacing the flexible circuit board with the gold finger 30, and the gold finger 30 is arranged on the surface of the protective plate 20, so that the gold finger 30 does not need to be bent, and the injection molded part 40 does not need to provide a groove for the gold finger 30 to accommodate the gold finger 30. It is only necessary to set an avoidance hole 401 on the protective plate 20 to avoid the gold finger 30, so that the size of the injection molded part 40 can be reduced, and the thickness of the injection molded part 40 does not need to be large, so that the size of the battery body 10 can be increased while the size of the battery remains unchanged, so that the energy density of the battery is improved, and thus the capacity of the battery is improved. That is, in the embodiment of the present application, by arranging the gold finger 30 on the surface of the protective plate 20 away from the top surface 101, it is equivalent to replacing the flexible circuit board in the related art with the gold finger 30, thereby canceling the flexible circuit board on the protective plate 20, so that the size of the injection molded part 40 can be reduced, and then the size of the battery body 10 can be increased while the size of the battery remains unchanged, thereby improving the energy density and capacity of the battery.

[0041] It should be noted that in the related art, when the battery is packaged, a flexible circuit board is connected to the protection board 20, and a connector is provided on the flexible circuit board. When the protection board 20 is packaged by the injection molding part 40, the injection molding part 40 encapsulates part of the flexible circuit board, and the other part of the flexible circuit board is bent. A groove is provided on the surface of the injection molding part 40 away from the battery body 10 to accommodate the bent flexible circuit board, and then the connector is connected to the part to be connected. The bent flexible circuit board requires a certain space. In order to accommodate the bent flexible circuit board, the thickness of the injection molding part 40 needs to be increased. However, this method will inevitably lead to a reduction in the size of the battery body 10 while keeping the battery size unchanged, resulting in a decrease in the energy density and capacity of the battery. In the embodiment of the present application, a gold finger 30 is provided on the surface of the protective plate 20 away from the top surface 101, thereby replacing the flexible circuit board with the gold finger 30. As a result, there is no need to provide a groove on the injection molded part 40 to accommodate the flexible circuit board, and the injection molded part 40 does not need to be larger in size. On the premise that the size of the battery remains unchanged, the size saved by the injection molded part 40 can be used as a basis for increasing the size of the battery cell body 10. The size of the battery cell body 10 can be increased, thereby improving the energy density and capacity of the battery.

[0042] In addition, in the embodiment of the present application, the specific number of the gold fingers 30 can be set according to actual needs, for example, the number of the gold fingers 30 is 5, and for another example, the number of the gold fingers 30 is 7. The specific number of the gold fingers 30 is not limited in the embodiment of the present application. In addition, the number of the avoidance holes 401 on the injection molded part 40 can be equal to the number of the gold fingers 30.

[0043] In addition, in the embodiment of the present application, the injection molded part 40 may be an injection molding glue, and the specific type of the injection molding glue may be selected according to the needs of battery packaging, which is not limited in the embodiment of the present application.

[0044] In addition, in the embodiment of the present application, the battery may further include adhesive tape, which is attached to the outer surface of the injection molded part 40 .

[0045] In addition, in the embodiment of the present application, the protection plate 20 may be a printed circuit board (PCB).

[0046] In addition, in some embodiments, a sink groove 402 is disposed on the surface of the injection molded part 40 facing away from the top surface 101 , and the avoidance hole 401 is disposed at the bottom of the sink groove 402 .

[0047] Since the avoidance hole 401 is arranged at the bottom of the sink 402, when the gold finger 30 needs to be connected to the part to be connected, the thickness of the injection molded part 40 through which the part to be connected passes will be reduced due to the sink 402, so that the part to be connected can be easily connected to the gold finger 30, avoiding the problem that the injection molded part 40 may be too large and it is not conducive to the part to be connected to the gold finger 30. That is, by arranging the avoidance hole 401 at the bottom of the sink 402, the gold finger 30 can be easily connected to the part to be connected.

[0048] In addition, in some embodiments, the battery cell body 10 also has a side seal 13 bent toward the side wall surface of the battery cell body 10, and a protruding structure 14 protruding from the top surface 101 is formed at the intersection of the side seal 13 and the top seal 11; an avoidance groove 201 is opened in the middle of the protective plate 20, the protruding structure 14 is located in the avoidance groove 201, and a reinforcement structure 50 is arranged on the protective plate 20, and the reinforcement structure 50 is located around the avoidance groove 201.

[0049] Since an avoidance groove 201 is opened in the middle of the protection plate 20 and the protruding structure 14 is located in the avoidance groove 201, the protruding structure 14 can pass through the avoidance groove 201, so that the protection plate 20 can avoid the protruding structure 14. When packaging the batteries, for batteries of the same size, the protruding structure 14 and the protection plate 20 can jointly occupy the space above the top surface 101, thereby reducing the influence of the protruding structure 14 on the assembly of the protection plate 20, thereby increasing the effective space of the battery cell body 10. Furthermore, since a reinforcing structure 50 is provided on the protective plate 20 and the reinforcing structure 50 is located around the avoidance groove 201, the reinforcing structure 50 can increase the strength of the portion of the protective plate 20 around the avoidance groove 201. That is, even if the avoidance groove 201 is opened on the protective plate 20, so that the strength of the reinforcing plate is reduced, the existence of the reinforcing structure 50 can improve the strength of the protective plate 20 at the position where the avoidance groove 201 is opened, which is equivalent to solving the problem of insufficient strength of the protective plate 20 caused by opening the avoidance groove 201 on the protective plate 20 through the reinforcing structure 50, thereby avoiding the problem of deformation and fracture of the protective plate 20 caused during the battery assembly process, thereby improving the battery yield.

[0050] It should be noted that, in the embodiment of the present application, the middle portion of the protection plate 20 can be understood as the position where the orthographic projection of the protection plate 20 on the top surface 101 and the orthographic projection of the protruding structure 14 on the top surface 101 overlap.

[0051] In addition, in the embodiment of the present application, the reinforcement structure 50 may have different forms, which are specifically described by taking the following as examples:

[0052] Form (1): The battery may have a first direction X, a second direction Y and a third direction Z that intersect each other; the plane formed by the first direction X and the second direction Y is parallel to the plane where the protective plate 20 is located, and the top sealing edge 11 and the protective plate 20 are stacked and distributed along the third direction Z; the protective plate 20 has a first side surface 21 and a second side surface 22 that are opposite to each other along the first direction X, the avoidance groove 201 is connected to the first side surface 21, and a boss 221 is provided on the second side surface 22, the boss 221 is opposite to the avoidance groove 201 in the first direction X, and the boss 221 forms a reinforcement structure 50.

[0053] Since the avoidance groove 201 is connected to the first side surface 21, the existence of the avoidance groove 201 will reduce the strength of the first side surface 21 of the protective plate 20 in the middle of the protective plate 20, and a boss 221 is provided on the second side surface 22, and the boss 221 is opposite to the avoidance groove 201 in the first direction X, so that the boss 221 can strengthen the strength of the middle part of the protective plate 20, that is, the existence of the boss 221 is equivalent to compensating for the strength loss of the protective plate 20 due to the opening of the avoidance groove 201, thereby avoiding the problem of insufficient strength of the protective plate 20.

[0054] It should be noted that the length of the boss 221 can be greater than the length of the avoidance groove 201, wherein the length of the avoidance groove 201 is: the distance between two opposite groove walls of the avoidance groove 201 along the second direction Y; the length of the boss 221 is: the distance between two opposite ends of the boss 221 along the second direction Y. Through such an arrangement, it can be ensured that the boss 221 can completely cover the area of ​​the avoidance groove 201 in the first direction X, so that the effect of the boss 221 compensating the strength of the protection plate 20 is effectively improved.

[0055] It should also be noted that in the embodiments of the present application, the X-axis direction intersects with the Z-axis direction, the X-axis direction intersects with the Y-axis direction, and the Y-axis direction intersects with the Z-axis direction. For ease of explanation, the first direction is defined as the X-axis direction, the second direction is defined as the Y-axis direction, and the third direction is defined as the Z-axis direction. Further explanation, the definition of vertical in the specification should be understood as vertical within a 10% fluctuation of 90 degrees, that is, the angle between the first direction X and the second direction Y defined as between 80 degrees and 90 degrees should be understood as vertical.

[0056] In addition, in some embodiments, a first reinforcing sheet 222 is disposed on the boss 221 , and the first reinforcing sheet 222 covers the boss 221 and a portion of the surface of the protection plate 20 that is away from the top surface 101 .

[0057] Through such a configuration, not only the boss 221 can strengthen the strength of the protective plate 20, but the first reinforcing sheet 222 can also strengthen the strength of the boss 221. Therefore, the existence of the first reinforcing sheet 222 can further improve the strength of the protective plate 20, so that the strength of the protective plate 20 can be effectively guaranteed.

[0058] It should be noted that the first reinforcing sheet 222 can be bonded to the boss 221 and the protective plate 20 by adhesive, so as to facilitate the installation of the first reinforcing sheet 222. Of course, the first reinforcing sheet 222 can also be installed in other ways, for example, the first reinforcing sheet 222 is installed on the boss 221 and the protective plate 20 by screws. This embodiment of the present application is not limited here.

[0059] It should also be noted that the length of the first reinforcing sheet 222 may be equal to the length of the boss 221 . Of course, the length of the first reinforcing sheet 222 may be less than the length of the boss 221 , but equal to the length of the avoidance groove 201 .

[0060] In addition, in the embodiment of the present application, the first reinforcing sheet 222 may be a steel sheet. Of course, the first reinforcing sheet 222 may also be other types, for example, the first reinforcing sheet 222 is a reinforcing sheet made of FR4 material. This embodiment of the present application does not limit this.

[0061] Method (2): The battery has a first direction X, a second direction Y and a third direction Z that intersect each other, the plane formed by the first direction X and the second direction Y is parallel to the plane where the protective plate 20 is located, and the top sealing edge 11 and the protective plate 20 are stacked and distributed along the third direction Z; the reinforcement structure 50 is a second reinforcement sheet, and the second reinforcement sheet covers the protective plate 20 on the side of the avoidance groove 201 away from the notch of the top surface 101 in the third direction Z.

[0062] Since the reinforcing structure 50 is a second reinforcing sheet, the second reinforcing sheet covers the side of the protection plate 20 where the notch of the avoidance groove 201 is away from the top surface 101 in the third direction Z. Therefore, the second reinforcing sheet can only occupy the size of the top of the protection plate 20 and only occupy the space of the size of the second reinforcing sheet in the third direction Z. Therefore, the size of the battery as a whole in the second direction Y will not be increased due to the provision of the third reinforcing sheet. That is, by providing the second reinforcing sheet, it is possible to ensure that the size of the battery will not increase significantly while increasing the strength of the protection plate 20.

[0063] It should be noted that the length of the second reinforcing sheet can be greater than the length of the avoidance groove 201, wherein the length of the avoidance groove 201 is: the distance between two opposite groove walls of the avoidance groove 201 along the second direction Y; the length of the second reinforcing sheet is: the distance between two opposite ends of the second reinforcing sheet along the second direction Y. Through such an arrangement, it can be ensured that the second reinforcing sheet can completely cover the area of ​​the avoidance groove 201 in the first direction X, so that the effect of the second reinforcing sheet compensating the strength of the protective plate 20 is effectively improved.

[0064] In addition, the second reinforcing sheet can be bonded to the protective plate 20 by adhesive, so as to facilitate the installation of the second reinforcing sheet. Of course, the second reinforcing sheet can also be installed in other ways, for example, the second reinforcing sheet is installed on the protective plate 20 by screws. This embodiment of the present application is not limited here.

[0065] In addition, in the embodiment of the present application, the second reinforcing sheet may be a steel sheet, and of course, the second reinforcing sheet may also be other types, for example, the second reinforcing sheet is a reinforcing sheet made of FR4 material, which is not limited in the embodiment of the present application.

[0066] In addition, in some embodiments, the battery further includes an electronic component 100 , and the electronic component 100 is disposed inside the protection plate 20 .

[0067] Since the electronic component 100 is arranged inside the protective plate 20, when the battery is packaged, the electronic component 100 will not occupy the additional size of the battery in the direction from the top surface 101 to the top sealing edge 11, that is, when the battery is packaged, only the circuit board needs to be packaged, and the electronic component 100 is inside the circuit board. The electronic component 100 will not occupy the space on the surface of the circuit board, and will not occupy the size of the battery in the direction from the top surface 101 to the top sealing edge 11, so that when the battery is packaged, the size of the electronic component 100 itself can be used as the basis for increasing the size of the battery body 10, thereby increasing the size of the battery body 10. That is, by arranging the electronic component 100 inside the protective plate 20, when the battery is packaged, for batteries of the same size, the size of the battery body 10 can be increased, which is beneficial to the improvement of the energy density of the battery.

[0068] It should be noted that the electronic component 100 can be disposed inside the protection plate 20 through special processes such as wafer packaging or embedding process.

[0069] In addition, in some embodiments, the battery has a third direction Z, the top sealing edge 11 and the protective plate 20 are stacked along the third direction Z, and the protective plate 20 has a first surface 23 and a second surface 24 relative to each other along the third direction Z; the first surface 23 faces the top sealing edge 11, and a fixing groove is provided on the second surface 24, and an electronic component 100 is embedded in the fixing groove.

[0070] Since the electronic component 100 is embedded in the fixing groove, when the battery is packaged, the size of the battery occupied by the electronic component 100 is smaller in the direction from the top surface 101 to the top sealing edge 11, that is, when the battery is packaged, the size of the electronic component 100 is smaller, so for batteries of the same size, the size of the battery body 10 can be increased, thereby improving the energy density of the battery. That is, by providing the fixing groove on the second surface 24 and embedding the electronic component 100 in the fixing groove, it is equivalent to that the fixing groove can avoid the electronic component 100, so that the size of the battery occupied by the electronic component 100 is reduced, and the size of the battery body 10 can be increased, thereby increasing the energy density of the battery.

[0071] It should be noted that a plurality of fixing grooves may be provided on the second surface 24 , and an electronic component 100 is embedded in each fixing groove.

[0072] In addition, in some embodiments, the battery may further include an easy-to-tear sticker 200 and a handle 300; the easy-to-tear sticker 200 simultaneously covers at least three surfaces of each battery cell body 10 in at least two battery bodies; the portion of the easy-to-tear sticker 200 on the battery cell body 10 has at least two relatively arranged notches, and at least one handle 300 is arranged in each notch.

[0073] In the embodiment of the present application, the tear-off sticker 200 not only has the function of fixing and insulating, but also because the portion of the tear-off sticker 200 on the battery body 10 has at least two relatively arranged notches, each notch is provided with a handle 300, so the battery can be removed by the handle 300, which is convenient for the later disassembly and assembly of the battery. That is, by providing the tear-off sticker 200, it is convenient to connect at least two battery bodies, and by providing the handle 300, the tear-off sticker 200 can be removed or installed.

[0074] In the embodiment of the present application, since the battery cell body 10 has a top surface 101, a bent top seal 11 is provided on the top surface 101, the top seal 11 is connected to the pole ear 12, the protective plate 20 and the top seal 11 are stacked and distributed, and the top seal 11 is located between the protective plate 20 and the top surface 101, and the pole ear 12 is electrically connected to the protective plate 20, therefore, the protective plate 20 can protect the interior of the battery cell body 10 through the pole ear 12. Since the protective plate 20 is provided with a gold finger 30 on the surface facing away from the top surface 101, and the injection molded part 40 encapsulates the protective plate 20 and the top sealing edge 11, when encapsulating the battery, the protective plate 20 and the sealing edge can be encapsulated by the injection molded part 40, and an avoidance hole 401 is provided on the injection molded part 40, and the avoidance hole 401 is opposite to the gold finger 30, so that the avoidance hole 401 can avoid the gold finger 30, and does not affect the connection between the gold finger 30 and the part to be connected. In addition, the protective plate 20 is connected to the part to be connected through the gold finger 30, and the flexible circuit board on the protective plate 20 is cancelled. That is, it is equivalent to replacing the flexible circuit board with the gold finger 30, and the gold finger 30 is arranged on the surface of the protective plate 20, so that the gold finger 30 does not need to be bent, and the injection molded part 40 does not need to provide a groove for the gold finger 30 to accommodate the gold finger 30. It is only necessary to set an avoidance hole 401 on the protective plate 20 to avoid the gold finger 30, so that the size of the injection molded part 40 can be reduced, and the thickness of the injection molded part 40 does not need to be large, so that the size of the battery body 10 can be increased while the size of the battery remains unchanged, so that the energy density of the battery is improved, and thus the capacity of the battery is improved. That is, in the embodiment of the present application, by arranging the gold finger 30 on the surface of the protective plate 20 away from the top surface 101, it is equivalent to replacing the flexible circuit board in the related art with the gold finger 30, thereby canceling the flexible circuit board on the protective plate 20, so that the size of the injection molded part 40 can be reduced, and then the size of the battery body 10 can be increased while the size of the battery remains unchanged, thereby improving the energy density and capacity of the battery.
