[0045] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0046] As Figures 1 to 22 shown, in the first aspect, the embodiment of the present utility model provides a cover plate 10 assembly. The cover plate 10 assembly includes: a cover plate 10 having a first end face and a second end face 11 oppositely arranged along the first direction; a plurality of first poles 21 and a plurality of second poles 22, and the plurality of first poles 21 and the plurality of second poles 22 are both arranged on the cover plate 10 at intervals; a plurality of first connecting members 31 and a plurality of second connecting members 32 are arranged on the second end face 11. The first connecting member 31 is connected to the first pole 21 in a one-to-one correspondence, and the second connecting member 32 is connected to the second pole 22 in a one-to-one correspondence. There is a gap between any one first connecting member 31 and any one second connecting member 32; among them, at least the mutually approaching parts of the first connecting member 31 and the adjacent second connecting member 32 are provided with an insulating structure 40, and the insulating structure 40 is arranged on the sides of the first connecting member 31 and the second connecting member 32 away from the cover plate 10.

[0047] Applying the technical solution of the present utility model, a plurality of first pole columns 21 and a plurality of second pole columns 22 are arranged on the first end face of the cover plate 10, and a plurality of first connectors 31 and a plurality of second connectors 32 are arranged on the second end face 11 of the cover plate 10. The plurality of first pole columns 21 and the plurality of second pole columns 22 are both arranged at intervals on the first end face. The first connectors 31 are connected to the first pole columns 21 in a one-to-one correspondence, and the second connectors 32 are connected to the second pole columns 22 in a one-to-one correspondence. There is a gap between any one of the first connectors 31 and any one of the second connectors 32. In this way, the risk of short circuit caused by the overlap of the first connector 31 and the adjacent second connector 32 can be prevented. At the same time, at least the mutually approaching parts of the first connector 31 and the adjacent second connector 32 are provided with an insulating structure 40. In this way, the risk of internal short circuit caused by the overlap of the first connecting piece and the adjacent second connecting piece can be further prevented, thereby improving the safety of the battery and being beneficial to meeting the use requirements of users.

[0048] It can be understood that the polarities of the first pole column 21 and the second pole column 22 are opposite, and the polarities of the first connector 31 and the second connector 32 are also opposite. When the first pole column 21 is of positive polarity, the first connector 31 is also of positive polarity, then the second pole column 22 is of negative polarity, and the second connector 32 is also of negative polarity. Conversely, when the first pole column 21 is of negative polarity, the first connector 31 is also of negative polarity, then the second pole column 22 is of positive polarity, and the second connector 32 is also of positive polarity. No specific limitation is made here.

[0049] In the embodiment of the present application, when the numbers of both the first pole column 21 and the second pole column 22 are 2, they can be arranged and combined in the situations such as positive positive negative negative, positive negative negative positive, positive negative positive negative, etc., as long as the use requirements of the device can be met; when the numbers of both the first pole column 21 and the second pole column 22 are 3, they can be arranged and combined in the situations such as positive positive positive negative negative negative, positive positive negative positive positive negative, positive positive negative positive negative positive, positive positive negative negative positive positive, positive negative positive positive negative positive, etc. In this way, the applicability and application range of the battery core can be improved as much as possible.

[0050] In the application, X is the second direction, which is the length direction of the cover plate 10, and the first direction is the thickness direction of the cover plate 10.

[0051] As Figures 1 to 4 shown, the above picture shows the situation when both the first pole column 21 and the second pole column 22 are set to two. Taking the first pole column 21 as the positive pole column, the first connector 31 as the positive polarity, the second pole column 22 as the negative pole column, and the second connector 32 also as the negative polarity as an example, the above picture shows the situation of positive negative positive negative (positive and negative poles staggered).

[0052] As Figures 5 to 8As shown, the above picture shows the case when both the first pole 21 and the second pole 22 are set to two. Taking the first pole 21 as the positive pole, the first connecting piece 31 as the positive polarity, the second pole 22 as the negative pole, and the second connecting piece 32 also as the negative polarity as an example, the above picture shows the situation of positive-positive-negative-negative (positive and negative poles on the same side).

[0053] As Figures 9 to 12 shown, the above picture shows the case when both the first pole 21 and the second pole 22 are set to two. Taking the first pole 21 as the positive pole, the first connecting piece 31 as the positive polarity, the second pole 22 as the negative pole, and the second connecting piece 32 also as the negative polarity as an example, the above picture shows the situation of positive-negative-negative-positive.

[0054] As Figures 13 to 16 shown, the above picture shows the case when both the first pole 21 and the second pole 22 are set to two. Taking the first pole 21 as the positive pole, the first connecting piece 31 as the positive polarity, the second pole 22 as the negative pole, and the second connecting piece 32 also as the negative polarity as an example, the above picture shows the situation of negative-positive-positive-negative.

[0055] As Figures 17 to 18 shown, the above picture shows the case when both the first pole 21 and the second pole 22 are set to three. Taking the first pole 21 as the positive pole, the first connecting piece 31 as the positive polarity, the second pole 22 as the negative pole, and the second connecting piece 32 also as the negative polarity as an example, the above picture shows the situation of positive and negative poles alternating.

[0056] As Figures 19 to 20 shown, the above picture shows the case when both the first pole 21 and the second pole 22 are set to three. Taking the first pole 21 as the positive pole, the first connecting piece 31 as the positive polarity, the second pole 22 as the negative pole, and the second connecting piece 32 also as the negative polarity as an example, the above picture shows the situation of positive-positive-positive-negative-negative-negative (positive and negative poles on the same side).

[0057] In the present application, when at least one first pole 21 and at least one second pole 22 are arranged adjacent to each other in the first direction, the remaining multiple first poles 21 and the remaining multiple second poles 22 can be arranged parallel to each other in the second direction.

[0058] Furthermore, the multiple first connecting pieces 31 and the multiple second connecting pieces 32 are arranged at intervals in the second direction, and the second direction is perpendicular to the first direction. Such an arrangement can not only make the overall cover plate 10 assembly more beautiful and tidy, but also facilitate the connection with external components. Optionally, the multiple first poles 21 and the multiple second poles 22 can also be arranged at intervals in other directions as long as the use requirements of the device can be met. In the present application, the interval arrangement specifically means that the multiple first poles 21 and the multiple second poles 22 are located on the same straight line. The polarity of adjacent two poles is not limited here, and the specific arrangement should be selected according to the use environment of the device.

[0059] Specifically, a plurality of first connecting members 31 and a plurality of second connecting members 32 are alternately arranged in sequence in the second direction. With this arrangement, the first pole 21 and the second pole 22 are evenly distributed on the cover plate 10, which can make the current density more uniform during battery charging and discharging, thereby reducing the heat generation of the battery to maintain the stable operation of the battery.

[0060] Furthermore, the number of the first connecting members 31 is equal to the number of the second connecting members 32. With this arrangement, the stability of the battery output can be guaranteed to maintain the normal operation of the battery.

[0061] Specifically, insulating structures 40 are provided at both ends of the first connecting member 31 and the second connecting member 32 in the second direction. This can further improve the insulation effect of the first connecting member 31 and the second connecting member 32, preventing the first connecting piece and the second connecting member 32 from overlapping and causing the risk of internal short circuit, thus increasing the safety of the battery.

[0062] Furthermore, the extension length of the insulating structure 40 in the second direction is L, and 2 mm ≤ L ≤ 3 mm. When L > 3 mm, the extension length of the insulating material in the second direction is too large, which increases the use cost of the insulating material. At the same time, it will also reduce the welding area between the first connecting member 31 or the second connecting member 32 and the tab, making it inconvenient for welding. When L < 2 mm, the extension length of the insulating material in the second direction is too small, which will make the cross-sectional area of the insulating material smaller, and it is easy for the adjacent first connecting member 31 and the second connecting member 32 to overlap and generate the risk of short circuit, resulting in the inability to meet the insulation requirements of the first connecting member 31 and the second connecting member 32. Therefore, 2 mm ≤ L ≤ 3 mm is beneficial not only to reducing production costs and realizing mass production of components, but also to ensuring the welding area between the first connecting member 31 or the second connecting member 32 and the tab, facilitating welding, and the cross-sectional area of the insulating material is large, which can avoid the risk of adjacent first connecting member 31 and second connecting member 32 overlapping and generating short circuit, meeting the insulation requirements of the first connecting member 31 and the second connecting member 32. Optionally, L can be set to values such as 2 mm, 2.5 mm or 3 mm, etc. The specific setting should be selected according to the use environment of the first connecting member 31 and the second connecting member 32, and no specific limitation is made here.

[0063] Specifically, the first connector 31 and the second connector 32 have a protrusion 50 extending along the second direction, and the protrusion 50 of the first connector 31 and the protrusion 50 of the adjacent second connector 32 are arranged in opposite directions. This arrangement ensures that the interval between the adjacent first connectors 31 and the second connectors 32 is as large as possible, thereby avoiding the risk of short circuit caused by overlapping between the first connector 31 and the adjacent second connector 32 as much as possible, which is conducive to maintaining the stability of the battery during operation.

[0064] Furthermore, the insulating structure 40 includes a ceramic silicone rubber layer or a fluororubber layer. Optionally, in other embodiments of the present application, the insulating structure 40 can also be set to TC composite tape, mica plate, mica roll, ceramic, polytetrafluoroethylene, etc., as long as it can meet the insulation requirements of the battery.

[0065] In the present application, the extension length of the insulating structure 40 in the width direction of the cover plate 10 is equal to the extension length of the first connector 31 in the width direction of the cover plate 10. By setting the above structure, the covering of the first connector 31 by the insulating structure 40 can be ensured. Of course, the extension length of the insulating structure 40 in the width direction of the cover plate 10 can also be set to be equal to the extension length of the second connector 32 in the width direction of the cover plate 10, so that the covering effect of the insulating structure 40 on the first connector 31 and the second connector 32 can be ensured, thereby further preventing the risk of short circuit between components.

[0066] Specifically, the first connector 31 includes an aluminum connector, and the second connector 32 includes a copper connector. Since the positive electrode of the battery is realized by an oxidation reaction, this means that the entire electrochemical process must be completed by an oxidation reaction. In this process, the chemical reaction of the positive electrode releases a large amount of heat, and aluminum can withstand higher temperatures, so it is selected as the positive electrode material. In addition, aluminum has a lower potential and better conductivity. The negative electrode of the battery is realized by a reduction reaction, that is, the entire electrochemical process must be completed by a reduction reaction. Unlike the positive electrode, the chemical reaction of the negative electrode consumes a large amount of heat, and copper has better conductivity and can withstand such reaction conditions at room temperature, so it is selected as the negative electrode material. In addition, the higher potential of copper can also ensure the flow of current, so that the battery can work more stably.

[0067] In a second aspect, an embodiment of the present utility model provides a lithium battery, and the lithium battery includes the above-mentioned cover plate 10 assembly.

[0068] Applying the technical solution of the present utility model, a plurality of first pole columns 21 and a plurality of second pole columns 22 are provided on the first end surface of the cover plate 10, and a plurality of first connectors 31 and a plurality of second connectors 32 are provided on the second end surface 11 of the cover plate 10. Moreover, the plurality of first pole columns 21 and the plurality of second pole columns 22 are arranged at intervals on the first end surface. The first connectors 31 are connected to the first pole columns 21 in a one-to-one correspondence, and the second connectors 32 are connected to the second pole columns 22 in a one-to-one correspondence. There is a gap between any one of the first connectors 31 and any one of the second connectors 32. This can prevent the risk of short circuit caused by the overlap of the first connector 31 and the adjacent second connector 32. At the same time, at least the mutually approaching parts of the first connector 31 and the adjacent second connector 32 are provided with an insulating structure 40. This can further prevent the risk of internal short circuit caused by the overlap of the first connecting piece and the adjacent second connecting piece, thereby improving the safety of the battery and being beneficial to meeting the usage requirements of users.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0070] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description.
