[0033] AsFigures 1 to 8 As shown, the battery comprises: a shell 10, a first current collector 20 and a pole 30; the first current collector 20 is arranged in the interior of the shell 10, the shell 10 is provided with a mounting hole 101, and the pole 30 is arranged through the mounting hole 101; the first current collector 20 is provided with a connecting groove 201, and part of the pole 30 is embedded in the connecting groove 201; the connecting groove 201 is provided with conductive glue 100, and the pole 30 is connected with the first current collector 20 through the conductive glue 100.

[0034] In the embodiment of the present application, since the shell 10 is provided with the mounting hole 101, the pole 30 can pass through the mounting hole 101 and be connected with the inner wall of the mounting hole 101 through the interference of the sealing member 323, so that part of the pole 30 is located in the interior of the shell 10. Since the first current collector 20 is arranged in the interior of the shell 10, and the first current collector 20 is provided with the connecting groove 201, part of the pole 30 located in the interior of the shell 10 can be embedded in the connecting groove 201, and the connecting groove 201 is provided with the conductive glue 100, so that after part of the pole 30 is embedded in the connecting groove 201, the conductive glue 100 can connect the pole 30 with the first current collector 20, that is, the structure of the pole 30 embedded in the connecting groove 201 is connected with the first current collector 20 through the conductive glue 100. That is, in the embodiment of the present application, by arranging the connecting groove 201 on the first current collector 20 and arranging the conductive glue 100 in the connecting groove 201, part of the pole 30 can be embedded in the connecting groove 201, so that the pole 30 is connected with the first current collector 20 through the conductive glue 100, thereby avoiding welding between the first current collector 20 and the pole 30, and further avoiding the problem of dust pollution in the interior of the battery caused by welding. In addition, by arranging the conductive glue 100, the problem of welding through the first current collector 20 can be avoided in the process of welding, and the problem of virtual welding can also be avoided in the process of welding, thereby avoiding the problem of high cost of detecting virtual welding. That is, in the embodiment of the present application, the pole 30 and the first current collector 20 are fixed and electrically connected through the conductive glue 100. Since the conductive glue 100 is filled and solidified after standing, compared with the scheme of welding connection between the pole 30 and the first current collector 20, the assembly process can be simplified, the dust pollution caused by welding between the pole 30 and the first current collector 20 in the interior of the battery can be avoided, the first current collector 20 can be prevented from being welded through, the safety and reliability of the battery can be effectively guaranteed, and the cost is effectively reduced.

[0035] In the embodiment of the present application, the pole 30 and the first current collector 20 connected through the conductive glue 100 means that the structure of the pole 30 embedded in the connecting groove 201 is connected with the first current collector 20 through the conductive glue 100.

[0036] It should be noted that once the part of the pole 30 is embedded in the connecting groove 201 on the first current collector 20, the conductive glue 100 in the connecting groove 201 contacts the part of the pole 30, and then the conductive glue 100 can bond the part of the pole 30, avoiding the part of the pole 30 from being separated from the connecting groove 201, so that the part of the pole 30 is connected with the first current collector 20, and the presence of the conductive glue 100 can also make the pole 30 and the first current collector 20 conductive, ensuring the normal use of the battery.

[0037] In addition, in the embodiments of the present application, as shown in Figure 2 The battery can further include a second current collector 50, a winding core 40, and a cover plate 60. The shell 10 has an opening 102. The second current collector 50 and the winding core 40 are located inside the shell 10. The winding core 40 is located between the first current collector 20 and the second current collector 50 along the height direction Z of the battery. The cover plate 60 covers the opening 102.

[0038] In addition, in some embodiments, as shown in Figure 4 , Figure 6 , Figure 7 and Figure 8 The pole 30 can include a pole plate 31. The pole plate 31 has opposite first and second faces 311 and 314 along the height direction Z of the battery. The first face 311 faces the first current collector 20. The first face 311 is provided with a connecting boss 312. The second face 314 is provided with a fixing boss 315. The connecting boss 312 is embedded in the connecting groove 201 and contacts the conductive glue 100. The pole plate 31 is arranged inside the shell 10 and on the surface of the first current collector 20 facing the mounting hole 101. The fixing boss 315 passes through the mounting hole 101, and at least part of the fixing boss 315 is located outside the shell 10.

[0039] Due to the first face 311 of the pole plate 31 being provided with the connecting boss 312 and the second face 314 being provided with the fixing boss 315, when assembling the battery, the pole plate 31 can be arranged inside the shell 10 and on the surface of the first current collector 20 facing the mounting hole 101, so that the pole plate 31 is blocked by the shell 10 and is not easy to be separated from the shell 10, and the fixing boss 315 is arranged in the mounting hole 101, so that at least part of the fixing boss 315 is located outside the shell 10, facilitating the subsequent connection of the fixing boss 315 with other components, i.e., the subsequent connection of the pole 30 with other components. In addition, the connecting boss 312 is embedded in the connecting groove 201 on the first current collector 20, and the connecting boss 312 is in contact with the conductive adhesive 100 in the connecting groove 201, so that the conductive adhesive 100 connects the connecting boss 312 with the first current collector 20, so that the first current collector 20 and the connecting boss 312 are connected and conductive, and then the first current collector 20 and the pole 30 are connected and conductive. That is, by arranging the connecting boss 312 on the first face 311 of the pole plate 31 and arranging the fixing boss 315 on the second face 314 of the pole plate 31, the pole 30 can be conveniently installed in the shell 10, and the pole 30 is prevented from being separated from the shell 10, and the pole 30 can also be conveniently connected with the first current collector 20.

[0040] In addition, in some embodiments, as shown in Figure 4 、 Figure 6 、 Figure 7 and Figure 8 , the connecting boss 312 has opposite first and second ends 3121 and 3122 in the height direction Z of the battery, the first end 3121 is fixedly connected with the first face 311, the projection of the first end 3121 on the first face 311 is located in the projection of the second end 3122 on the first face 311, the connecting groove 201 has a groove opening 2011 and a groove bottom 2012, the projection of the groove opening 2011 on the first face 311 is located in the projection of the groove bottom 2012 on the first face 311; wherein the second end 3122 is located inside the connecting groove 201.

[0041] Since the projection of the first end 3121 on the first face 311 is located in the projection of the second end 3122 on the first face 311, that is, from the direction facing the first face 311, the size of the second end 3122 is greater than the size of the first end 3121. Since the projection of the slot opening 2011 of the connecting groove 201 on the first face 311 is located in the projection of the groove bottom 2012 on the first face 311, that is, from the direction facing the first face 311, the size of the slot opening 2011 of the connecting groove 201 is smaller than the size of the groove bottom 2012, that is, the connecting groove 201 has a structure that the slot opening 2011 is small and the groove space is large. Therefore, after the second end 3122 of the connecting boss 312 is arranged in the connecting groove 201, that is, the larger second end 3122 is arranged in the connecting groove 201, when the connecting boss 312 is forced to separate from the connecting groove 201, the second end 3122 will be blocked by the slot opening 2011 of the connecting groove 201 which is smaller in size, so that the connecting boss 312 is not easy to separate from the connecting groove 201. If the first end 3121, the second end 3122, the slot opening 2011 and the groove bottom 2012 are projected on the first face 311, respectively, from the direction facing the first face 311, the projection of the first end 3121 on the first face 311 is located in the projection of the second end 3122 on the first face 311, and the projection of the slot opening 2011 on the first face 311 is located in the projection of the groove bottom 2012 on the first face 311. Such a structure can effectively ensure the connection stability of the connecting boss 312 and the first current collecting plate 20, and avoid the problem that the connecting boss 312 and the first current collecting plate 20 are easily separated, that is, avoid the problem that the pole 30 and the first current collecting plate 20 are easily separated.

[0042] It should be noted that in the embodiments of the present application, after the second end 3122 is located in the connecting groove 201, the projection of the slot opening 2011 of the connecting groove 201 on the first face 311 is located in the projection of the second end 3122 of the connecting boss 312 on the first face 311, that is, the size of the second end 3122 is greater than the size of the slot opening 2011 of the connecting groove 201. The connecting boss 312 can plastically deform under stress, and the cooperation between the connecting boss 312 and the connecting groove 201 can be formed by riveting, so as to ensure that the connecting boss 312 can be installed in the connecting groove 201.

[0043] In addition, in some embodiments, the outer surface profile of the connecting boss 312 is in the shape of a circular truncated cone.

[0044] By setting the outer surface profile of the connecting boss 312 in the shape of a circular truncated cone, the structure of the circular truncated cone is relatively easy to process when the connecting boss 312 is processed, thereby facilitating the processing of the connecting boss 312. That is, by setting the outer surface profile of the connecting boss 312 in the shape of a circular truncated cone, the connecting boss 312 can be easily processed, thereby improving the production efficiency of the battery.

[0045] Of course, in the embodiments of the present application, the connecting boss 312 can also have other shapes, for example, the profile of the connecting boss 312 is in the shape of a trapezoidal body, and for another example, the shape of the connecting boss 312 can be determined according to the shape of the connecting groove 201, that is, when the connecting boss 312 is embedded in the connecting groove 201, the shape of the connecting boss 312 is determined according to the shape of the slot of the connecting groove 201, so as to facilitate the embedding of the connecting boss 312 in the connecting groove 201. In the embodiments of the present application, only the size of the first end 3121 of the connecting boss 312 is smaller than the size of the second end 3122, and the specific shape of the connecting boss 312 is not limited in the embodiments of the present application.

[0046] In addition, in some embodiments, as shown in Figure 6 The first through hole 313 is provided on the pole plate 31 in the height direction Z of the battery, the second through hole 3123 is provided on the connecting boss 312 in the height direction Z of the battery, and the communication groove 3151 is provided on the fixing boss 315 in the height direction Z of the battery. The first through hole 313, the second through hole 3123 and the communication groove 3151 are communicated to inject the conductive adhesive 100 into the connecting groove 201.

[0047] Since the first through hole 313 on the pole plate 31, the second through hole 3123 on the connecting boss 312 and the communication groove 3151 on the fixing boss 315 are communicated, after the connecting boss 312 is embedded in the connecting groove 201 on the first current collector 20 during the production of the battery, the conductive adhesive 100 can be injected into the communication groove 3151, and then the conductive adhesive 100 flows through the first through hole 313, flows through the second through hole 3123, and finally flows into the connecting groove 201, so that the connecting boss 312 is in contact with the conductive adhesive 100, and then the connecting boss 312 is connected with the first current collector 20 through the conductive adhesive 100. That is, by communicating the first through hole 313, the second through hole 3123 and the communication groove 3151, it is convenient to inject the conductive adhesive 100 into the connecting groove 201, so that the connecting boss 312 is connected with the first current collector 20, and then the connection between the first current collector 20 and the pole 30 is facilitated.

[0048] In addition, in the embodiments of the present application, as shown in Figure 7 The first through hole 313, the second through hole 3123 and the communication groove 3151 are all provided with the conductive adhesive 100.

[0049] In the process of producing the battery, after the connecting boss 312 is embedded in the connecting groove 201 on the first current collector 20, the conductive glue 100 can be injected into the communicating groove 3151, and then the conductive glue 100 flows through the first through hole 313 and the second through hole 3123, and finally flows into the connecting groove 201. After the conductive glue 100 is filled in the connecting groove 201, the first through hole 313, the second through hole 3123 and the communicating groove 3151 all have the conductive glue 100, so that the conductive glue 100 in the first through hole 313, the second through hole 3123 and the communicating groove 3151 is fused with the conductive glue 100 in the connecting groove 201, so that the pole plate 31 and the first current collector 20 are connected more firmly. That is, by arranging the conductive glue 100 in the first through hole 313, the second through hole 3123 and the communicating groove 3151, the firmness of the connection between the first current collector 20 and the pole plate 31 can be further improved, and the problem of easy separation of the pole 30 and the first current collector 20 can be avoided.

[0050] In addition, in some embodiments, as shown in Figure 6 and Figure 7 The projection of the communicating groove 3151 on the second surface 314 surrounds the projection of the first through hole 313 on the second surface 314; the communicating groove 3151 has a bottom wall, and the bottom wall of the communicating groove 3151 is provided with a groove 316, and the groove 316 is provided with the conductive glue 100.

[0051] Since the projection of the communicating groove 3151 on the second surface 314 surrounds the projection of the first through hole 313 on the second surface 314, in the process of producing the battery, after the connecting boss 312 is embedded in the connecting groove 201 on the first current collector 20, when the conductive glue 100 is injected into the communicating groove 3151, the conductive glue 100 can flow to the bottom wall of the communicating groove 3151 and flow into the first through hole 313, and finally flow into the connecting groove 201 through the first through hole 313. Since the bottom wall of the communicating groove 3151 is provided with the groove 316, once the conductive glue 100 enters the communicating groove 3151 after the conductive glue 100 is filled in the connecting groove 201, so that the communicating groove 3151 has the conductive glue 100, the existence of the groove 316 is equivalent to increasing the space for accommodating the conductive glue 100 in the communicating groove 3151, so that the amount of the conductive glue 100 accommodated in the communicating groove 3151 increases, and the existence of the groove 316 also makes the bottom wall of the communicating groove 3151 present a concave-convex shape, thereby facilitating the conductive glue 100 to be bonded to the bottom wall of the communicating groove 3151. That is, by arranging the groove 316 on the bottom wall of the communicating groove 3151, and arranging the conductive glue 100 in the groove 316, the conductive glue 100 in the communicating groove 3151 can be firmly bonded to the bottom wall of the communicating groove 3151, and the pole plate 31 and the first current collector 20 are connected more firmly through the conductive glue 100.

[0052] In addition, in the embodiment of the present application, the groove 316 on the bottom wall of the communication groove 3151 can have different setting modes, which are specifically illustrated by the following examples:

[0053] Mode (1): The groove 316 surrounds the first through hole 313, and the projection of the groove 316 on the first surface 311 has a ring shape.

[0054] By surrounding the first through hole 313 with the groove 316, once the conductive glue 100 is arranged in the communication groove 3151 and the first through hole 313, the conductive glue 100 in the communication groove 3151 is first connected firmly with the bottom wall of the communication groove 3151 due to the existence of the groove 316, and then the conductive glue 100 in the communication groove 3151 is connected firmly with the conductive glue 100 in the first through hole 313, ensuring that the pole plate 31 is connected firmly with the first current collector 20.

[0055] Mode (2): The number of grooves 316 is multiple, and the multiple grooves 316 are distributed at intervals on the second surface 314.

[0056] Since the number of grooves 316 is multiple, once the conductive glue 100 is arranged in the communication groove 3151, the conductive glue 100 will enter the multiple grooves 316, so that the multiple grooves 316 can make the bottom wall of the communication groove 3151 more uneven, thereby making the conductive glue 100 in the communication groove 3151 more firmly connected with the bottom wall of the communication groove 3151.

[0057] It should be noted that the number of grooves 316 can be set according to actual needs, for example, the number of grooves 316 is 10, and for another example, the number of grooves 316 is 15. The specific number of grooves 316 is not limited in the embodiment of the present application.

[0058] In addition, in the embodiment of the present application, the battery can further include a fixing assembly 32, which is connected with the part of the pole 30 located outside the shell 10 and fixes the part of the pole 30. The fixing assembly 32 can include a riveting piece 321, a plastic piece 322, and a sealing piece 323. The sealing piece 323 seals the gap between the pole 30 and the mounting hole 101, and the riveting piece 321 and the plastic piece 322 fix the part of the pole 30 located outside the shell 10. In addition, the inside of the shell 10 of the battery can be provided with an internal plastic 324, and the pole plate 31 is connected with the inner wall of the shell 10 through the internal plastic 324.

[0059] In the embodiment of the present application, since the mounting hole 101 is arranged on the shell 10, the pole 30 can pass through the mounting hole 101 and be connected to the inner wall of the mounting hole 101 in an interference fit through the sealing member 323, so that part of the pole 30 is located inside the shell 10. Since the first current collecting plate 20 is arranged inside the shell 10, and the connecting groove 201 is arranged on the first current collecting plate 20, part of the pole 30 located inside the shell 10 can be embedded in the connecting groove 201, and the conductive glue 100 is arranged in the connecting groove 201, so that after part of the pole 30 is embedded in the connecting groove 201, the conductive glue 100 can connect the pole 30 and the first current collecting plate 20, that is, the structure of the pole 30 embedded in the connecting groove 201 is connected to the first current collecting plate 20 through the conductive glue 100. That is, in the embodiment of the present application, by arranging the connecting groove 201 on the first current collecting plate 20 and arranging the conductive glue 100 in the connecting groove 201, part of the pole 30 can be embedded in the connecting groove 201, so that the pole 30 is connected to the first current collecting plate 20 through the conductive glue 100, thereby avoiding welding between the first current collecting plate 20 and the pole 30, and further avoiding the problem of dust pollution in the battery caused by welding. In addition, by arranging the conductive glue 100, the problem of welding through the first current collecting plate 20 in the welding process can be avoided, and the problem of virtual welding in the welding process can be avoided, thereby avoiding the problem of high cost of detecting virtual welding. That is, in the embodiment of the present application, the pole 30 and the first current collecting plate 20 are fixed and electrically connected through the conductive glue 100. Since the conductive glue 100 is filled and then left to solidify, compared with the scheme of welding connection between the pole 30 and the first current collecting plate 20, the assembly process can be simplified, the dust pollution in the battery caused by welding between the pole 30 and the first current collecting plate 20 can be avoided, and the first current collecting plate 20 can be prevented from being welded through, so that the safety and reliability of the battery can be effectively guaranteed, and the cost is effectively reduced.
