[0010] According to the battery of the first aspect of the present application, at least the following beneficial effects are achieved:

[0011] The battery of the present application, by setting the pressing strip, makes the first glue blocking part on the pressing strip connected to the surface of all the battery monomers in the adjacent two rows of battery monomers, and makes the first glue blocking part cover the first gap channel between the adjacent two rows of battery monomers, at the same time, makes the projection of the opening part and the first gap channel in the height direction staggered, and makes the opening part on the pressing strip connected to the surface of the battery monomers through the glue, in this way, the pressing strip realizes the limiting and fixing of all the battery monomers, and the glue will be stopped by the first glue blocking part on the first gap channel when flowing along the surface of the battery monomers to the first gap channel between the adjacent two rows of battery monomers, which reduces the probability of glue overflow into the gap between the adjacent two battery monomers, and effectively improves the yield of the battery.

[0012] In some embodiments, the first glue blocking part connects the surfaces of all the battery monomers in the adjacent two rows of battery monomers through the first glue film, and the first glue film covers the first gap channel.

[0013] In this way, on the one hand, the connection area of the pressing strip and all the battery monomers is increased, the connection strength of the pressing strip and all the battery monomers is improved, and thus the limiting and fixing effect of the pressing strip on all the battery monomers is improved. On the other hand, the first glue film is used to more comprehensively block the first gap channel due to its excellent density, so that the glue in the opening part will be stopped by the first glue film on the first gap channel when flowing along the surface of the battery monomers to the first gap channel between the adjacent two rows of battery monomers, which further reduces the probability of glue overflow into the gap between the adjacent two battery monomers, and effectively improves the yield of the battery.

[0014] In some embodiments, the opening part includes at least two hole grooves spaced apart along the first direction, and in a projection plane perpendicular to the third direction, projections of the two hole grooves along the third direction respectively at least partially coincide with projections of two battery monomers adjacent along the first direction along the third direction, and the hole grooves are used to be connected to the surfaces of the corresponding battery monomers through glue.

[0015] In this way, a single hole groove is connected to the surfaces of multiple battery monomers in each row of battery monomers through glue, the connection area of the pressing strip and all the battery monomers is increased, the connection strength of the pressing strip and all the battery monomers is improved, and thus the limiting and fixing effect of the pressing strip on all the battery monomers is improved.

[0016] In some embodiments, the opening part includes at least a plurality of hole grooves spaced apart along the second direction, and in a projection plane perpendicular to the third direction, projections of the plurality of hole grooves along the third direction respectively correspond one-to-one to projections of a plurality of battery monomers arranged along the second direction along the third direction, and the hole grooves are used to be connected to the surfaces of the corresponding battery monomers through glue.

[0017] In this way, all the battery monomers in the two adjacent columns of battery monomers can be connected with the corresponding holes and grooves on the pressing strip through the glue, the connection area of the pressing strip and all the battery monomers is increased, the connection strength of the pressing strip and all the battery monomers is improved, and thus the limiting and fixing effect of the pressing strip on all the battery monomers is improved.

[0019] In this way, when the glue in the opening part flows along the surface of the battery monomer to the gap between the two adjacent columns of battery monomers and the gap between the two adjacent rows of battery monomers, the glue is stopped by the first glue blocking part and the second glue blocking part at the corresponding gap, thereby reducing the probability of glue overflow into the gap between any two adjacent battery monomers and further improving the yield of the battery.

[0020] In some embodiments, the second glue blocking part connects the surfaces of the two adjacent rows of the battery monomers facing the third direction through a second glue film, and the second glue film covers at least part of the second gap channel.

[0021] In this way, on the one hand, the connection area of the pressing strip and all the battery monomers is further increased, the connection strength of the pressing strip and all the battery monomers is improved, and thus the limiting and fixing effect of the pressing strip on all the battery monomers is improved. On the other hand, the second glue film is used to more comprehensively block the second gap channel due to its excellent density, so that the glue in the opening part is stopped by the second glue film on the second gap channel when flowing along the surface of the battery monomer to the second gap channel between the two adjacent rows of battery monomers, thereby further reducing the probability of glue overflow into the gap between the two adjacent battery monomers and effectively improving the yield of the battery.

[0022] In some embodiments, the first glue blocking part is connected with the second glue blocking part at both ends along the first direction.

[0023] In this way, all the second glue blocking parts on the pressing strip are fixedly connected with the surfaces of the battery monomers, thereby improving the strength of the limiting and fixing of all the battery monomers.

[0024] In some embodiments, the first glue blocking part and all the second glue blocking parts are integrally formed.

[0025] In this way, the difficulty of processing and forming the pressing strip can be reduced, and the processing flow of the pressing strip is simplified.

[0026] In some embodiments, the pressing strip is provided with a stopper at both ends along the first direction, the stopper extends along the second direction, the stopper protrudes from the surface of the battery monomer, and the first glue blocking part and the hole part are located between the two stoppers.

[0027] In this way, the stopper can stop the glue overflowing out of the hole part on the pressing strip, reduce the risk of glue overflowing onto the electronic elements on the surface of the battery monomer, and further improve the yield of the battery.

[0028] In some embodiments, the battery further comprises a battery monomer group and two limiting end plates, the battery monomer group comprises a plurality of battery monomers arranged along the second direction, the limiting end plate extends along the first direction to abut a plurality of battery monomer groups arranged along the first direction at the same time, and the two limiting end plates are respectively located at both ends of the battery monomer group along the second direction.

[0029] In this way, the two limiting end plates can limit and fix all battery monomers in the battery in the second direction, reduce the probability of displacement of all battery monomers in the second direction due to thermal expansion, and maintain the stable performance of the battery in the subsequent use process.

[0030] In some embodiments, the pressing strip is provided with a connecting part at both ends, and the connecting part is detachably connected with the limiting end plate.

[0031] In this way, the stability of the connection between the pressing strip and the plurality of battery monomers can be improved, and the probability of displacement, movement and misalignment of the pressing strip can be further reduced.

[0050] In addition, if these terms "first", "second" appear, these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0051] In the present application, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be understood in a broad sense. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited.

The first feature can be below or below and below the second feature, or it can only mean that the first feature is lower in height than the second feature.

[0053] It should be noted that if an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or there can be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be an intermediate element.

[0054] At present, from the development of market situation, the application of battery is more and more widely. The battery is not only applied to the energy storage power supply system of hydropower, thermal power, wind power and solar power station, but also widely used in electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment and aerospace and other fields. With the continuous expansion of the application field of battery, the demand of its market is also increasing.

[0055] The battery is composed of one or more battery monomers. For each battery, the plurality of battery monomers that constitute it can be connected in series or in parallel or in mixed connection. Among them, mixed connection means that there are series connection and parallel connection in the plurality of battery monomers.

[0056] The battery monomer is the smallest unit to constitute the battery, and in the structure of the battery monomer, it includes the shell, the electrolyte and the electrode assembly. The electrode assembly is the component where the electrochemical reaction occurs in the battery monomer, and the electrode assembly includes the positive plate, the negative plate and the separator. The shell can include one or more electrode assemblies, and the electrode assembly is mainly formed by winding or stacking the positive plate and the negative plate, and the separator is usually arranged between the positive plate and the negative plate.

[0057] The shell is an open-ended structure with a hollow interior. The electrode assembly is arranged inside the shell, and the end cover is arranged at the opening of the shell. The end cover is used to close the opening to form the internal environment of the battery cell. Of course, the end cover and the shell can also be integrated. In some embodiments, the end cover and the shell can form a common connecting surface before other components enter the shell. When it is necessary to seal the interior of the shell, the end cover is used to close the shell. The shell can have various shapes and sizes, such as a cuboid, a cylinder, a hexagonal prism, etc. In some embodiments, the shape of the shell can be determined according to the specific shape and size of the electrode assembly. The shell can be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. The embodiments of the present application do not have special restrictions on this.

[0058] In the process of producing batteries, when assembling multiple battery cells into a box, glue is generally used to fix the battery cells.

[0059] In related technologies, in order to reduce the probability of glue overflowing into the gap between adjacent battery cells, a frame structure is generally arranged at the large face of the battery cell. The frame structure is fixed to the large face of the battery cell by glue, and the frame structure reduces the probability of glue overflowing into the gap between the two adjacent battery cells.

[0060] Alternatively, a glue blocking strip is directly glued to the large face of the battery cell by glue to directly block the gap between the two adjacent battery cells and reduce the probability of glue overflowing into the gap between the two adjacent battery cells.

[0061] However, the inventors have found that, whether the frame structure is glued to the large face of the battery cell by glue or the glue blocking strip is glued to the large face of the battery cell by glue, the glue will overflow upward or downward to the gap between the two adjacent battery cells under the pressure of gluing or the expansion pressure of the battery cell, resulting in quality problems of the battery and increasing the defective rate of the battery.

[0062] Therefore, in view of the problem that the glue is prone to overflowing into the gap between the adjacent battery cells and increasing the defective rate of the battery, one or more embodiments of the present application provide a battery. A pressing strip is arranged. The first glue blocking part on the pressing strip is connected to the surface of all battery cells in two adjacent rows of battery cells and covers the gap channel between the two adjacent rows of battery cells. The projection of the opening part and the first gap channel in the height direction is dislocated. The opening part on the pressing strip is connected to the surface of the battery cell by glue. In this way, the pressing strip can limit and fix all battery cells. When the glue flows along the surface of the battery cell to the gap channel between the adjacent battery cells, the glue is stopped by the first glue blocking part on the gap channel, reducing the probability of glue overflowing into the gap between the two adjacent battery cells and effectively improving the yield of the battery.

[0063] Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 4, FIG. 1 shows a schematic diagram of arrangement of a plurality of battery monomers in a battery according to an embodiment of the present application, and FIG. 2 shows a schematic diagram of cooperation of the plurality of battery monomers and a pressing strip in the battery according to an embodiment of the present application.

[0064] An embodiment of the present application provides a battery, which comprises a plurality of battery monomers 100 and a pressing strip 200.

[0065] The plurality of battery monomers 100 are arranged in a matrix along intersecting first and second directions X and Y, and a first gap channel S1 is formed between two adjacent columns of battery monomers 100 along the first direction X.

[0066] The pressing strip 200 comprises a first glue blocking part 210 and an opening part 220, the first glue blocking part 210 is connected to surfaces of the two adjacent columns of battery monomers 100 facing a third direction Z and covers at least the first gap channel S1, in a projection plane perpendicular to the third direction Z, a projection of the opening part 220 along the third direction Z is dislocated from a projection of the first gap channel S1, the opening part 220 is used to be connected to the surfaces of the battery monomers 100 facing the third direction Z by glue, and the first, second and third directions X, Y and Z are perpendicular to each other.

[0067] It should be noted that in the embodiments of the present application, the battery monomers 100 can be square bodies or cylindrical bodies, in some embodiments, the battery monomers 100 are square bodies, and correspondingly, the first direction X is a straight line direction, that is, a row direction, which also corresponds to a width direction of the battery, and the second direction Y is also a straight line direction, that is, a column direction, which also corresponds to a length direction of the battery. The third direction is also a straight line direction, which corresponds to a height direction of the battery, and the surface of the battery monomers 100 facing the third direction Z is a top surface of the battery monomers 100.

[0068] Referring to FIG. 1 and FIG. 2, in the embodiments of the present application, the plurality of battery monomers 100 can be arranged in a single row and two columns, it is easy to understand that the first gap channel S1 formed between the two adjacent columns of battery monomers 100 along the first direction X extends along the second direction Y. At this time, the pressing strip 200 has one, and the pressing strip 200 extends along the second direction Y.

[0069] The plurality of battery monomers 100 can also be arranged in a plurality of rows and a plurality of columns, at this time, the pressing strip 200 correspondingly has a plurality of, and the pressing strip 200 also extends along the second direction Y.

[0070] In the embodiments of the present application, the material of the pressing strip 200 is not limited, and for example, the material of the pressing strip 200 is metal, so that the pressing strip 200 has good structural strength and is not easy to break. The first glue blocking part 210 and the opening part 220 of the pressing strip 200 are integrally formed, so that the overall pressing strip 200 has good structural strength. In addition, in the embodiments of the present application, the glue can be structural glue.

[0071] Based on the above description, referring to FIGS. 3 and 4, it can be easily understood that the first glue blocking part 210 is connected to the surfaces of all the battery monomers 100 in the adjacent two rows of battery monomers 100, and the first glue blocking part 210 covers at least the first gap channel S1 between the adjacent two rows of battery monomers 100. In this way, the first glue blocking part 210 blocks the first gap channel S1, and the pressing strip 200 is pre-fixed on the surfaces of the plurality of battery monomers 100, thereby reducing the probability of deviation and movement of the pressing strip 200.

[0072] It can be understood that, referring to FIGS. 3 and 4, after the pressing strip 200 is pre-fixed on the surface of the battery monomer 100, the opening part 220 on the pressing strip 200 is attached to the surface of the battery monomer 100, and the glue is applied to the inner wall of the opening part 220 and the surface of the battery monomer 100 corresponding to the opening part 220 through the glue application process or the glue injection process, so that the opening part 220 is connected to the surface of the battery monomer 100 through the glue, and the pressing strip 200 is secondarily fixed on the surface of the battery monomer 100. In this way, the pressing strip 200 achieves limiting and fixing of all the battery monomers 100, thereby reducing the probability of deviation and movement of the battery monomers 100 and maintaining the stable performance of the battery in the subsequent use process.

[0073] Referring to FIGS. 3 and 4, it should be noted that since the first glue blocking part 210 blocks the first gap channel S1, and in the projection plane perpendicular to the third direction Z, the projection of the opening part 220 along the third direction Z is dislocated from the projection of the first gap channel S1, the glue in the opening part 220 flows along the surface of the battery monomer 100 to the contact part of the first glue blocking part 210 and the battery monomer 100 and is stopped by the first glue blocking part 210, and at the same time, the glue in the opening part 220 flows along the surface of the battery monomer 100 to the first gap channel S1 between the adjacent two rows of battery monomers 100 and is also stopped by the first glue blocking part 210 on the first gap channel S1, thereby reducing the probability of overflow of the glue into the gap between the adjacent two battery monomers and improving the yield of the battery.

[0074] It is understandable that the battery of the embodiment of the application is provided with the pressing strip 200, the first glue blocking part 210 on the pressing strip 200 is connected to the surface of all the battery monomers 100 in the adjacent two rows of battery monomers 100, and the first glue blocking part 210 covers at least the first gap channel S1 between the adjacent two rows of battery monomers 100, at the same time, the projection of the opening part 220 in the height direction is dislocated from the first gap channel S1, and the opening part 220 on the pressing strip 200 is connected to the surface of the battery monomer 100 through the glue, so that the pressing strip 200 realizes the limiting and fixing of all the battery monomers 100, and the glue is blocked by the first glue blocking part 210 on the first gap channel S1 when flowing along the surface of the battery monomer 100 to the first gap channel S1 between the adjacent two rows of battery monomers 100, thereby reducing the probability of glue overflow into the gap between the adjacent two battery monomers, and effectively improving the yield of the battery.

[0075] In some embodiments of the application, referring to FIGS. 1, 2, 3 and 4, the first glue blocking part 210 is connected to the surface of all the battery monomers 100 in the adjacent two rows of battery monomers 100 through the first glue film (not shown in the figure), and the first glue film covers the first gap channel S1.

[0076] In some embodiments, the material of the first glue film is not limited, which can be 3M adhesive tape, PET double-sided adhesive film and the like.

[0077] Taking the first glue film as 3M double-sided adhesive film as an example, in the process of processing the pressing strip 200, the first glue film can be glued on one surface of the processing pressing strip 200, and then the opening part 220 and the first glue blocking part 210 on the pressing strip 200 are processed by using corresponding processing equipment such as punching equipment. In this process, the part of the first glue film corresponding to the opening part 220 of the pressing strip 200 is removed synchronously, and the remaining first glue film corresponds to the first glue blocking part 210 on the pressing strip 200. The opening part 220 on the pressing strip 200 is in a hollow state from top to bottom, and has no first glue film thereon. When the pressing strip 200 is assembled to the battery, the release paper on the first glue film is first torn off, so that the first glue blocking part 210 on the pressing strip 200 is connected to the surface of all the battery monomers 100 in the adjacent two rows of battery monomers 100 through the first glue film, and the pre-fixing of the pressing strip 200 is completed.

[0078] As can be appreciated, referring to FIGS. 3 and 4, the first glue blocking part 210 is fixed on the surfaces of all the battery monomers 100 in the two adjacent rows of battery monomers 100 by the first glue film and covers the first gap channel S1 between the two adjacent rows of battery monomers 100 by the first glue film. In this way, the first gap channel S1 is blocked by the first glue film and the pressing strip 200 is preliminarily fixed on the surfaces of the battery monomers 100 by the first glue film, so as to reduce the probability of deviation and movement of the pressing strip 200.

[0079] As can be appreciated, referring to FIGS. 3 and 4, after the pressing strip 200 is preliminarily fixed on the surfaces of the battery monomers 100, the opening part 220 on the pressing strip 200 is attached to the surfaces of the battery monomers 100, and the glue is applied to the inner wall of the opening part 220 and the surface of the battery monomer 100 corresponding to the opening part 220 by the gluing process or the injection process, so as to connect the opening part 220 to the surface of the battery monomer 100 by the glue and secondarily fix the pressing strip 200 on the surfaces of the battery monomers 100. In this way, the pressing strip 200 is fixed on the surfaces of all the battery monomers 100, so as to reduce the probability of deviation and movement of the battery monomers 100 and maintain the stable performance of the battery in the subsequent use.

[0080] As can be appreciated, referring to FIGS. 3 and 4, since the first gap channel S1 is blocked by the first glue blocking part 210, the glue in the opening part 220 is stopped by the first glue film on the first glue blocking part 210 when flowing along the surface of the battery monomer 100 to the contact position of the first glue blocking part 210 and the battery monomer 100, and the glue in the opening part 220 is also stopped by the first glue film on the first gap channel S1 when flowing along the surface of the battery monomer 100 to the first gap channel S1 between the two adjacent rows of battery monomers 100, so as to reduce the probability of overflow of the glue into the gap between the two adjacent battery monomers and improve the yield of the battery.

[0081] It is understandable that the battery of the embodiment of the application makes the first glue blocking part 210 fixed on the surface of all the battery monomers 100 in the adjacent two rows of battery monomers 100 through the first glue film, and covers the first gap channel S1 between the adjacent two rows of battery monomers 100 through the first glue film. On the one hand, the connecting area of the pressing strip 200 and all the battery monomers 100 is increased, the connecting strength of the pressing strip 200 and all the battery monomers 100 is improved, and thus the limiting and fixing effect of the pressing strip 200 on all the battery monomers 100 is improved. On the other hand, the first gap channel S1 is more comprehensively plugged by the excellent compactness of the first glue film, so that the glue in the hole part 220 is stopped by the first glue film on the first gap channel S1 in the process of flowing along the surface of the battery monomer 100 to the first gap channel S1 between the adjacent two rows of battery monomers 100, and the probability of glue overflow into the gap between the adjacent two battery monomers is further reduced, and the yield of the battery is effectively improved.

[0082] In some embodiments of the application, referring to 3, FIG. 4 and FIG. 5, the hole part 220 at least includes two hole grooves 221 distributed at intervals along the first direction X, and in the projection plane perpendicular to the third direction Z, the projections of the two hole grooves 221 along the third direction Z respectively at least partially coincide with the projections of the two battery monomers 100 adjacent along the first direction X along the third direction Z. The hole groove 221 is used to connect with the surface of the corresponding battery monomer 100 through the glue.

[0083] In some embodiments, the shape of the hole groove 221 can be, but is not limited to, a round hole, a long strip hole, a square hole, etc.

[0084] The hole groove 221 extends along the second direction Y, that is, the hole groove 221 extends along the length direction of the pressing strip, and the projection of each hole groove 221 on the third direction Z at least partially coincides with the projection of each row of battery monomers 100 on the third direction Z along the second direction Y.

[0085] In this way, a single hole groove 221 is connected to the surfaces of multiple battery monomers 100 in each row of battery monomers 100 through the glue, the connecting area of the pressing strip 200 and all the battery monomers 100 is increased, the connecting strength of the pressing strip 200 and all the battery monomers 100 is improved, and thus the limiting and fixing effect of the pressing strip 200 on all the battery monomers 100 is improved.

[0086] Moreover, the glue in the hole groove 221 can be stopped by the first glue blocking part 210 and / or the first glue film when flowing along the surface of the battery monomer 100 to the bottom surface of the first glue blocking part 210, so as to reduce the probability of glue overflow in the hole groove 221 into the first gap channel S1, that is, reduce the probability of glue overflow into the gap between the adjacent two battery monomers 100, and improve the yield of the battery.

[0087] In some embodiments of the present application, referring to 3, FIG. 4 and FIG. 5, the opening part 220 comprises a plurality of holes 221 arranged along the second direction Y, and in a projection plane perpendicular to the third direction Z, the projections of the plurality of holes 221 along the third direction Z respectively correspond to the projections of the plurality of battery monomers 100 along the third direction Z arranged along the second direction Y, and the hole 221 is used to connect the surface of the corresponding battery monomer 100 by glue.

[0088] In some embodiments, the hole 221 has a plurality of and is distributed in two rows, and the two rows of holes 221 are distributed by the first glue blocking part 210. Each row of holes 221 corresponds to a row of battery monomers 100, and each hole 221 is connected to the surface of the corresponding battery monomer 100 by glue.

[0089] In this way, all battery monomers 100 in the adjacent two rows of battery monomers 100 can be connected by glue and the bead 200 on the corresponding hole 221, increasing the connection area of the bead 200 and all battery monomers 100, and improving the connection strength of the bead 200 and all battery monomers 100, thereby improving the limiting and fixing effect of the bead 200 on all battery monomers 100.

[0090] Moreover, when the glue in the hole 221 flows to the bottom surface of the first glue blocking part 210 along the surface of the battery monomer 100, it can be stopped by the first glue blocking part 210 and / or the first glue film, thereby reducing the probability of glue overflow in all holes 221 into the first gap channel S1, i.e. reducing the probability of glue overflow into the gap between the adjacent two battery monomers 100, and improving the yield of the battery.

[0091] In addition, it should be noted that the hole 221 has a certain size and depth, which can store a certain amount of glue, reduce the probability of glue overflowing upward to the surface of the bead 200 and outward, reduce the risk of glue overflowing to the electronic elements on the battery monomer 100, and further improve the yield of the battery.

[0092] In some embodiments of the present application, referring to FIG. 1, FIG. 3 and FIG. 4, a second gap channel S2 is formed between the adjacent two rows of battery monomers 100 along the second direction Y, the second gap channel S2 is communicated with the first gap channel S1, and the second glue blocking part 230 is formed between the adjacent two holes 221 of the plurality of holes 221 arranged along the second direction Y, the second glue blocking part 230 is connected to the surface of the adjacent two rows of battery monomers 100 towards the third direction Z and covers at least part of the second gap channel S2.

[0093] It can be understood that, referring to FIG. 4 again, the second gap channel S2 extends along the first direction X and is connected perpendicularly with the first gap channel S1. Correspondingly, on the pressing strip 200, the second glue blocking part 230 extends along the first direction X and is connected perpendicularly with the first glue blocking part 210.

[0094] It can be understood that, the first gap channel S1 and the two second gap channels S2 intersect at a position to define an orthogonal gap region, and correspondingly, the first glue blocking part 210 and the two second glue blocking parts 230 intersect at a position to define an orthogonal glue blocking part covering and blocking the orthogonal gap region.

[0095] In this way, the glue in the opening part 220 flows along the surface of the battery monomer 100 to the gap between the two adjacent battery monomers 100 and the gap between the two adjacent rows of battery monomers 100, and is stopped by the first glue blocking part 210 and the second glue blocking part 230 at the corresponding gap, thereby reducing the probability of glue overflowing into the gap between any two adjacent battery monomers, and further improving the yield of the battery.

[0096] In some embodiments, referring to FIGS. 1, 3 and 4, the second glue blocking part 230 connects the surfaces of the two adjacent rows of battery monomers 100 facing the third direction Z through a second glue film (not shown in the figure), and the second glue film covers at least part of the second gap channel S2.

[0097] Like the first glue film, the material of the second glue film is not limited, and can be a 3M adhesive tape, a PET double-sided adhesive film, or the like.

[0098] Taking the second glue film as a 3M double-sided adhesive film as an example, when the pressing strip 200 is assembled to the battery, the release paper of the first glue film and the release paper of the second glue film can be torn off first, so that the first glue blocking part 210 on the pressing strip 200 connects the surfaces of all the battery monomers 100 in the two adjacent columns of battery monomers 100 through the first glue film, and at the same time, the second glue blocking part 230 on the pressing strip 200 connects the surfaces of the two adjacent battery monomers 100 in the two adjacent rows of battery monomers 100 through the second glue film.

[0099] In this way, the first blocking glue part 210 covers and blocks the first gap channel S1 between the two adjacent columns of battery cells 100 by the first glue film, the second blocking glue part 230 covers and blocks the second gap channel S2 between the two adjacent battery cells 100 in the two adjacent rows of battery cells 100 by the second glue film, in this way, the pressing strip 200 connects and fixes all the battery cells 100 of the two adjacent columns of battery cells 100 by the first glue film and the plurality of second glue films, further increases the connection area of the pressing strip 200 and the two columns of battery cells 100, improves the connection strength of the pressing strip 200 and the two columns of battery cells 100, and thus improves the limiting and fixing effect of the pressing strip 200 on the two columns of battery cells 100.

[0100] The plurality of pressing strips 200 cooperate with the corresponding first glue film and second glue film to limit and fix all the battery cells 100 arranged in rows and columns, reduce the probability of position deviation and misplacement of any two battery cells 100, and further improve the yield of the battery.

[0101] It can also be understood that, referring to FIG. 4, the position where the first glue film intersects with the two second glue films defines an orthogonal glue film part. The above-mentioned orthogonal blocking glue part covers and blocks the above-mentioned orthogonal gap area by the orthogonal glue film part.

[0102] It can be understood that, the battery of the embodiment of the application makes the second blocking glue part 230 connect the surfaces of the two adjacent battery cells 100 in the two adjacent rows of battery cells 100 by the second glue film, and cover at least part of the second gap channel S2 by the second glue film, on the one hand, further increases the connection area of the pressing strip 200 and all the battery cells 100, improves the connection strength of the pressing strip 200 and all the battery cells 100, and thus improves the limiting and fixing effect of the pressing strip 200 on all the battery cells 100. On the other hand, the second glue film is used to block the second gap channel S2, so that the glue in the opening part 220 flows along the surface of the battery cell 100 to the second gap channel S2 between the two adjacent rows of battery cells 100, and is stopped by the second glue film on the second gap channel S2, further reducing the probability of glue overflow into the gap between the two adjacent battery cells, and effectively improving the yield of the battery.

[0103] In some embodiments of the application, referring to FIG. 4, the first blocking glue part 210 is connected with the second blocking glue part 230 at both ends in the first direction X.

[0104] In some embodiments, on the pressing strip 200, there are two columns of second blocking glue parts 230, and all the second blocking glue parts 230 on each column of second blocking glue parts 230 are distributed at intervals in the second direction Y.

[0105] In this way, the second glue blocking portions 230 on the pressing strip 200 are fixedly connected to the surfaces of the battery monomers 100, thereby improving the strength of the limiting and fixing of the battery monomers 100.

[0106] When the pressing strip 200 is assembled to the corresponding position of the battery, the two adjacent hole grooves 221 in the first direction X are spaced by the first glue blocking portions 210, and the two adjacent hole grooves 221 in the second direction Y are spaced by the second glue blocking portions 230.

[0107] In this way, when the glue in the hole groove 221 flows along the surface of the battery monomer 100 to the first gap channel S1, the glue is blocked by the first glue blocking portion 210 and / or the first glue film, and when the glue in the hole groove 221 flows along the surface of the battery monomer 100 to the second gap channel S2, the glue is blocked by the second glue blocking portion 230 and / or the second glue film, thereby reducing the probability of glue overflowing into the gap between any two adjacent battery monomers, and further improving the yield of the battery.

[0108] In some embodiments of the present application, referring to FIGS. 4 and 5, the first glue blocking portions 210 and the second glue blocking portions 230 are integrally formed.

[0113] Of course, in other embodiments, during the processing of the gasket 200, a complete adhesive film can be first glued on the bottom surface of the gasket 200, and then the corresponding processing equipment is used to process all the holes and grooves 221 on the gasket 200. During this process, the part of the adhesive film corresponding to the upper and lower parts of the hole part 220 of the gasket 200 is synchronously removed, so that the first blocking glue part 210 with the first adhesive film glued on the bottom surface and the second blocking glue part 230 with the second adhesive film glued on the bottom surface are processed on the gasket 200.

[0114] It can be understood that by configuring the first adhesive film and the second adhesive film as an integral structure, the process of fixing the gasket 200 on the battery can be simplified, and the efficiency of assembling the battery with the gasket 200 can be improved.
