Description

Technical Field

[0001] The present application relates to the technical field of power batteries, and in particular to a battery cell assembly and a battery. Background Art

[0002] With the continuous development of the scientific and technological level and the diversification of user needs, new energy power battery technology has also developed rapidly. Among them, the design of the battery cell structure inside the battery is also constantly updated and iterated. And as a key component of the battery cell structure, the design of its sub-component, the stop frame, is particularly important.

[0003] Among them, the existing battery cell cover plate usually includes a cover plate body and a stop frame, and the cover plate body and the stop frame are stacked. In order to prevent unnecessary movement or deformation of the battery cell structure, the stop frame plays a role in fixing the wound core and insulation.

[0004] However, at present, the stop frame is usually a single-piece integrated stop frame. When matching a battery cell structure with a relatively large width dimension, the length of the stop frame is large, which will cause the problem of deformation and warping of the stop frame during the riveting or injection molding of the cover plate pole column. In addition, at present, the cover plate generally only has a single stop table surface. During the thermal runaway of the battery cell, the through hole of the stop frame is easily blocked by the wound core diaphragm, resulting in problems such as unsmooth exhaust.

[0043] As described in the background art, the current stopper frame is usually a single integral stopper frame. When matching a battery cell structure with a relatively large width dimension, the length of the stopper frame is relatively large, which may cause problems such as deformation and warping of the stopper frame during the riveting or injection molding of the cover plate pole post. In addition, the current cover plates generally only have a single stop table surface. During the thermal runaway of the battery cell, the through hole of the stopper frame is easily blocked by the winding core diaphragm, resulting in problems such as poor exhaust.

[0044] In view of the above technical problems, the embodiments of the present application provide a battery cell assembly and a battery. The battery cell assembly includes a battery cell unit and a stopper frame. The stopper frame is located at one end of the battery cell unit and is connected to the battery cell unit. On the side of the stopper frame facing the battery cell unit, there is a first stop platform, and a first sunken table surface is provided on the first stop platform. The first sunken table surface is not coplanar with the first stop platform, and the surface of the first sunken table surface facing the battery cell unit is higher than the surface of the first stop platform facing the battery cell unit. The battery includes at least one of the above battery cell assemblies. In this way, based on the battery cell structure, the present application can effectively solve the problem of deformation and warping of the stopper frame during the riveting or injection molding of the cover plate pole post due to the large length of the stopper frame caused by the large width dimension of the battery cell through the mutual cooperation between multiple stop platforms. In addition, the stopper frame provided by the present application has a double sunken table surface structure, effectively solving the problem of poor exhaust caused by the blockage of the through hole of the stopper frame by the winding core diaphragm under the thermal runaway state of the battery cell.

[0045] In order to make the above objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0046] The embodiments of the present application provide a battery cell assembly and a battery. On the basis of the battery cell structure, through the mutual cooperation between multiple stopping platforms, the problem that the stopping frame is deformed and warped during the riveting or injection molding of the cover plate pole due to the large width dimension of the battery cell and the large length of the stopping frame is effectively solved. In addition, the provided stopping frame has a double sunken table structure, which effectively solves the problem of poor exhaust caused by the blocking of the through hole of the stopping frame by the winding core diaphragm in the thermal runaway state of the battery cell. The following will introduce the specific structures of the battery cell assembly and the battery provided by the embodiments of the present application with reference to the accompanying drawings.

[0047] Referring to Figure 1 , in the first aspect of the embodiments of the present application, a battery cell assembly 100 is provided. Among them, the battery cell assembly 100 can be a cylindrical battery cell, or the battery cell assembly 100 can be a square shell battery cell, which is not limited in the present application. In the embodiments of the present application, the battery cell assembly 100 may include a battery cell unit 200 and a stopping frame 300. In a possible implementation manner, the shape of the stopping frame 300 may be a rectangular structure, or the orthographic projection of the stopping frame 300 facing the battery cell unit 200 may be a rectangular structure, and the shape of the stopping frame 300 is not limited in the present application. In the embodiments of the present application, the stopping frame 300 may be located at one end of the battery cell unit 200, and the stopping frame 300 may be fixedly connected to the battery cell unit 200. Among them, the stopping frame 300 may be fixedly connected to the battery cell unit 200 by welding or other means. In a possible implementation manner, a first stopping platform 311 may be provided on the surface of the stopping frame 300 facing the battery cell unit 200, and a first sunken table 314 may be provided on the first stopping platform 311. It can be understood that the surface of the first stopping platform 311 facing the battery cell unit 200 may be in contact with the battery cell unit 200, so that the first stopping platform 311 can be used to fix and limit the battery cell unit 200. In the embodiments of the present application, the first sunken table 314 and the first stopping platform 311 are not coplanar, and the surface of the first sunken table 314 facing the battery cell unit 200 may be higher than the surface of the first stopping platform 311 facing the battery cell unit 200. In this way, when the first stopping platform 311 is in contact with the battery cell unit 200, there will be a certain gap between the first sunken table 314 and the battery cell unit 200, providing a certain space for the exhaust of the battery cell unit 200 and making the exhaust process smoother.

[0048] Reference Figure 2 and Figure 3 In the specific implementation of this embodiment, the stop frame 300 may have a first surface 310 and a second surface 320. Among them, the first surface 310 may be arranged facing the battery cell unit 200, and the second surface 320 may be arranged facing away from the battery cell unit 200. The first stop platform 311 may protrude from the first surface 310, so as to facilitate the fixed connection between the first stop platform 311 and the battery cell unit 200. In a possible implementation manner, both ends of the first stop platform 311 may have a second sunk surface 315. The second sunk surface 315 may also protrude from the first surface 310. It can be understood that the surface of the second sunk surface 315 facing the battery cell unit 200 may be lower than the first surface 310, and the surface of the second sunk surface 315 facing the battery cell unit 200 may be higher than the surface of the first stop platform 311 facing the battery cell unit 200. The height of the second sunk surface 315 may be between the first stop platform 311 and the first surface 310, so that the second sunk surface 315 is not coplanar with the first surface 310 and the first stop platform 311. In this way, the setting of the second sunk surface 315 can further provide a certain space for the exhaust of the battery cell unit 200, and avoid the situation of contact and blockage between the first surface 310 and the battery cell unit 200.

[0049] Continue to refer to Figure 2 and Figure 3 Based on the above embodiment, the stop frame 300 may include a first connecting portion 330 and a second connecting portion 340. Among them, the first connecting portion 330 may be connected to the second connecting portion 340. In a possible implementation manner, the first stop platform 311 may be located on the first connecting portion 330. Of course, in another possible implementation manner, the first stop platform 311 may also be located on the second connecting portion 340. The embodiments of the present application do not limit this here. In this way, by setting the stop frame 300 as a split structure, when matching the battery cell assembly 100 with a larger width dimension, the problem that the stop frame 300 is deformed and warped during the riveting or injection molding process of the cover pole due to the large length of the stop frame 300 is avoided.

[0050] Continue to refer to Figure 3, on the basis of the above embodiments, the stop frame 300 may further include: a first positioning portion 350 and a second positioning portion 360. One of the first positioning portion 350 and the second positioning portion 360 may be located on the first connecting portion 330, and the other may be located on the second connecting portion 340. In a possible implementation, the first positioning portion 350 may be located on the first connecting portion 330, and the second positioning portion 360 may be located on the second connecting portion 340. Of course, in another possible implementation, the first positioning portion 350 may be located on the second connecting portion 340, and the second positioning portion 360 may be located on the first connecting portion 330. It can be understood that the first positioning portion 350 and the second positioning portion 360 may cooperate with each other, so that the first connecting portion 330 and the second connecting portion 340 are connected through the first positioning portion 350 and the second positioning portion 360.

[0051] Continue to refer to Figure 2 , on the basis of the above embodiments, the stop frame 300 may further include: a second stop platform 312 and a third stop platform 313. The second stop platform 312 and the third stop platform 313 may be respectively located at two ends of the stop frame 300. One of the second stop platform 312 and the third stop platform 313 may be located on the first connecting portion 330, and the other may be located on the second connecting portion 340. In a possible implementation, the second stop platform 312 may be located on the first connecting portion 330, and the third stop platform 313 may be located on the second connecting portion 340. Of course, in another possible implementation, the second stop platform 312 may be located on the second connecting portion 340, and the third stop platform 313 may be located on the first connecting portion 330. In the embodiments of the present application, both the second stop platform 312 and the third stop platform 313 may protrude from the first surface 310, and the surface of the second stop platform 312 facing the battery cell unit 200 may be in contact with the battery cell unit 200, and the surface of the third stop platform 313 facing the battery cell unit 200 may also be in contact with the battery cell unit 200. It can be understood that the heights of the first stop platform 311, the second stop platform 312, and the third stop platform 313 may be the same. In this way, the first stop platform 311, the second stop platform 312, and the third stop platform 313 can be in contact with the battery cell unit 200 to jointly fix and limit the battery cell unit 200.

[0052] Continue to refer to Figure 2, on the basis of the above embodiments, through holes 370 may be provided on the first stop platform 311, the second stop platform 312, the third stop platform 313, the first sunken table surface 314 and the second sunken table surface 315. Among them, in a possible implementation manner, the number of through holes 370 may be several, and this application does not limit the number of through holes 370 herein. In the embodiments of this application, the through holes 370 can be used for the gas in the battery cell assembly 100 to be discharged smoothly. In some other embodiments, the liquid in the battery cell assembly 100 can also be discharged through the through holes 370.

[0053] Continue to refer to Figure 2 , on the basis of the above embodiments, pole post positioning holes 380 may be provided on the stop frame 300. Among them, in a possible implementation manner, the number of pole post positioning holes 380 may be at least two, and this application does not limit the number of pole post positioning holes 380 herein. In the embodiments of this application, taking the number of pole post positioning holes 380 as two as an example, one of the two pole post positioning holes 380 may be located on the first connecting portion 330, and the other pole post positioning hole 380 is located on the second connecting portion 340. In a possible implementation manner, one of the pole post positioning holes 380 may be located on the first connecting portion 330, while the other pole post positioning hole 380 may be located on the second connecting portion 340. Of course, in another possible implementation manner, one of the pole post positioning holes 380 may be located on the second connecting portion 340, while the other pole post positioning hole 380 may be located on the first connecting portion 330. In the embodiments of this application, a pole post (not shown in the figure) may pass through the pole post positioning hole 380 and be electrically connected to the battery cell unit 200 by other means such as welding.

[0058] In the embodiments of the present application, based on the battery cell structure, through the mutual cooperation between multiple stop platforms, the problem that the stop frame 300 is deformed and warped during the riveting or injection molding of the cover plate pole due to the large width dimension of the battery cell and the large length of the stop frame 300 is effectively solved.
