[0038] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.

[0039] The battery provided in the embodiment of the present application may include a plurality of battery cells, each of which may include a battery cell, a top cover, and an adapter 10. The battery cell is provided with a tab, the top cover is provided with a pole, the top cover is provided with a pole, the top cover is provided on the top wall of the battery cell, and the adapter 10 is provided on the top cover. In actual use, the adapter 10 may be used to connect the tab and the pole to transmit current between the battery cell and an external device.

[0040] Figure 1 This is a schematic diagram of the structure of an adapter provided by an exemplary embodiment of the present application at a first viewing angle. Figure 1 As shown, the adapter sheet 10 provided in the embodiment of the present application may include a first connecting portion 100 and a second connecting portion 110, the first connecting portion 100 is connected to the second connecting portion 110, the first connecting portion 100 can be used to connect the pole, and the second connecting portion 110 can be used to connect the pole ear, so that the first connecting portion 100 and the second connecting portion 110 can transfer current between the pole and the pole ear.

[0041] In practical applications, when transferring the transfer sheet 10, it is necessary to stack multiple transfer sheets 10 on each other, and then use an adsorption device to absorb a single transfer sheet 10 for subsequent welding operations. The second connecting portion 110 of the transfer sheet 10 provided in the embodiment of the present application is provided with a first anti-adhesion area 111 on at least one side. After multiple transfer sheets 10 are stacked on each other, the first anti-adhesion area 111 can isolate two adjacent transfer sheets 10 from each other, so that a gap appears between two adjacent transfer sheets 10. In this way, adsorption between adjacent transfer sheets 10 can be avoided. When the suction device absorbs one of the transfer sheets 10, it is not easy for the adjacent transfer sheet 10 to be sucked up, so as to avoid the alarm of the suction device, and effectively improve the work efficiency.

[0042] In one embodiment, the first anti-sticking area 111 is provided on one side of the second connecting portion 110, and the first anti-sticking area 111 is not provided on the other side. When multiple adapter sheets 10 are stacked, for two adjacent adapter sheets 10, the side of one adapter sheet 10 on which the first anti-sticking area 111 is provided is bonded to the side of the other adapter sheet 10 on which the first anti-sticking area 111 is not provided. In this way, under the isolation effect of the first anti-sticking area 111, mutual adsorption of the two adjacent adapter sheets 10 can be avoided.

[0043] In one embodiment, the first anti-sticking area 111 is provided on both opposite sides of the second connecting portion 110. When a plurality of adapter sheets 10 are stacked, for two adjacent adapter sheets 10, the side of one adapter sheet 10 provided with the first anti-sticking area 111 is bonded to the side of the other adapter sheet 10 provided with the first anti-sticking area 111. In this way, the anti-adsorption effect is better, and the mutual adsorption of the two adjacent adapter sheets 10 can be avoided.

[0044] In one embodiment, at least one side of the first connecting portion 100 may also be provided with a second anti-adhesion area 101 (eg Figure 5 As shown in the figure, which will be described in detail later), in this way, when multiple adapter sheets 10 are stacked on each other, under the joint action of the second anti-sticking area 101 and the first anti-sticking area 111, adsorption between adjacent adapter sheets 10 can be further avoided. When the suction device absorbs one of the adapter sheets 10, it is not easy for the adjacent adapter sheets 10 to be sucked up, thereby avoiding the alarm of the suction device and effectively improving the work efficiency.

[0045] Figure 2 A schematic structural diagram of an adapter sheet provided for another exemplary embodiment of the present application. Figure 3 This is a schematic diagram of the structure of a transfer sheet provided by another exemplary embodiment of the present application. Figure 2 and Figure 3 As shown, the first anti-adhesion area 111 includes a rough structure 113, and the rough structure 113 can assist the first anti-adhesion area 111 to play the aforementioned anti-adsorption role.

[0046] like Figure 2 As shown, in one embodiment, the rough structure 113 may include a plurality of grooves, and the plurality of grooves are spaced apart in the first anti-adhesion area 111. The plurality of grooves may allow a gap to exist between two adjacent adapter sheets 10, thereby playing the aforementioned anti-adsorption role. In practical applications, the plurality of grooves may be distributed in the shape of regular patterns such as rectangles and circles, or in the shape of other irregular patterns.

[0047] In one embodiment, the rough structure 113 may include a plurality of protrusions, which are spaced apart in the first anti-adhesion area 111. The plurality of protrusions may allow a gap to exist between two adjacent adapter sheets 10, thereby playing the aforementioned anti-adsorption role. In practical applications, the plurality of protrusions may be distributed in the shape of regular patterns such as rectangles and circles, or in the shape of other irregular patterns.

[0048] In one embodiment, the rough structure 113 may include a plurality of convex strips, and the plurality of convex strips are distributed at intervals or cross-distributed with each other (eg Figure 3 As shown in FIG. 1 , there can be a gap between two adjacent adapter sheets 10, thereby playing the aforementioned anti-adsorption role. The shape of the convex strip can include cylindrical, prismatic, and the like.

[0049] In one embodiment, the rough structure 113 may include a plurality of grooves and a plurality of protrusions, and the plurality of grooves and the plurality of protrusions are spaced apart to form an uneven surface, which can also play the aforementioned anti-adsorption role.

[0050] It should be noted that the aforementioned rough structure 113 can be formed by processes such as sandblasting, scraping, mechanical grinding, stamping, laser engraving, corrosion, and electroplating.

[0051] It should be noted that the shapes of the aforementioned grooves and protrusions may include circular, prismatic, elliptical, etc.

[0052] It should be understood that if the roughness of the rough structure 113 is too small, it will be difficult for the first anti-adhesion area 111 provided with the rough structure 113 to prevent adsorption. Therefore, the roughness A of the rough structure 113 is limited to the following range in the embodiment of the present application: A ≥ Ra12.5. In this way, it can be effectively ensured that the first anti-adhesion area 111 provided with the rough structure 113 can play a better anti-adsorption role.

[0053] In one embodiment, the first anti-adhesion area 111 may include a pit, which may occupy all or part of the overall area of ​​the first anti-adhesion area 111 (optionally, the pit occupies more than 50% of the overall area of ​​the first anti-adhesion area 111). It should be understood that the pit can cause a gap between two adjacent adapter sheets 10, so that the first anti-adhesion area 111 plays the aforementioned anti-adsorption role.

[0054] It should be noted that the side wall of the pit can be tilted to form a draft angle (the angle between the side wall and the bottom wall of the pit), which can facilitate the removal of the adapter sheet 10 from the mold during the casting process to improve the demoulding efficiency. Optionally, the draft angle can be selected in the range of 45°-60°, for example, the draft angle can be 45°, 50°, 60°, etc.

[0055] In one embodiment, the number of the pits may be one, two, or more.

[0056] In one embodiment, the side wall of the pit can transition to the surface of the adapter plate 10 through an arc transition or an irregular shape transition. In this way, during the welding process of the adapter plate 10, the arc transition or the irregular shape transition part can help prevent high reflection during laser welding.

[0057] It should be understood that if the depth of the pit is large, it will not only increase the difficulty of processing, the loss of the processing mold, and increase the manufacturing cost, but also cause the second connection part 110 to have a low strength, affecting the service life of the adapter 10; if the depth of the pit is small, it will make it difficult for the first anti-adhesion area 111 to achieve the aforementioned anti-adsorption effect. Therefore, it is necessary to limit the depth of the pit to a certain range. Specifically, the depth of the pit is B, the thickness of the second connection part 110 is C, and B and C meet: 5% C ≤ B ≤ 20% C. In this way, under the premise of ensuring that the first anti-adhesion area 111 can achieve the aforementioned anti-adsorption effect, it can be ensured that the second connection part 110 has sufficient strength, and at the same time, the difficulty of processing the pit can be reduced, and the manufacturing difficulty and manufacturing cost can be reduced.

[0058] In one embodiment, the first anti-adhesion area 111 may include a convex block, which may occupy all or part of the overall area of ​​the first anti-adhesion area 111 (optionally, the convex block occupies more than 50% of the overall area of ​​the first anti-adhesion area 111). It should be understood that the convex block may cause a gap between two adjacent adapter sheets 10, so that the first anti-adhesion area 111 plays the aforementioned anti-adsorption role.

[0059] It should be understood that if the height of the bump is too large, it will cause scratches to the adjacent adapter sheet 10 . Therefore, the height D of the bump is limited to the following range: 0<D≤0.2 mm to reduce the scratches caused by the bump to the adjacent adapter sheet 10 .

[0060] In one embodiment, the number of the protrusions may be one, two, or more.

[0061] Figure 4 This is a schematic diagram of the structure of a transfer sheet provided by another exemplary embodiment of the present application. Figure 4 As shown, the first anti-sticking area 111 includes an anti-sticking coating 115, which can be used to isolate adjacent stacked adapter sheets 10 to avoid electrostatic effects on adjacent adapter sheets 10, and can also avoid adsorption and bonding problems between adjacent adapter sheets 10 due to cold welding.

[0062] In one embodiment, the material of the anti-stick coating 115 can be silicone oil, paraffin, polytetrafluoroethylene, etc.

[0063] In one embodiment, the anti-stick coating 115 can not only isolate adjacent adapter sheets 10 but also have a certain lubricity, so that the problem of adjacent adapter sheets 10 sticking to each other can be further avoided.

[0064] Figure 5 A schematic structural diagram of an adapter provided by an exemplary embodiment of the present application at a second viewing angle. Figure 6A schematic diagram of a structure of stacking multiple adapter sheets provided by an exemplary embodiment of the present application. Figure 5 and Figure 6 As shown, the first connection portion 100 and the second connection portion 110 are bent relative to each other, which can adapt to the internal space layout of the battery cell, ensure effective connection between the pole and the lug within a limited space, and improve the stability and safety of the battery cell.

[0065] It should be understood that when the first connection portion 100 and the second connection portion 110 are relatively bent, after a plurality of adapter sheets 10 are stacked, they tend to tilt toward one side, affecting the overall stability after stacking. Figure 6 As shown, in the process of stacking multiple adapter sheets 10, two adjacent adapter sheets 10 are stacked alternately, that is, among two adjacent adapter sheets 10, the second connection portion 110 of one adapter sheet 10 is stacked with the second connection portion 110 of the other adapter sheet 10, and the first connection portion 100 of one adapter sheet 10 is arranged opposite to the first connection portion 100 of the other adapter sheet 10, and are respectively arranged on both sides of the stacking area of ​​the two second connection portions 110. In this way, it can avoid that the multiple adapter sheets 10 are tilted toward one side after being stacked, and the stability of the multiple adapter sheets 10 after being stacked can be effectively improved.

[0066] like Figure 5 As shown, a welding area 112 is provided on one side of the second connecting portion 110, and the welding area 112 is used to connect the tab. Figure 1 and Figure 5 The welding area 112 and the first anti-sticking area 111 are located on opposite sides of the second connecting portion 110. In this way, the influence of the first anti-sticking area 111 on the welding operation between the welding area 112 and the pole lug can be reduced, thereby ensuring the welding quality between the welding area 112 and the pole lug.

[0067] In one embodiment, the surface of one side of the second connection portion 110 where the welding area 112 is provided may be smooth, so that the welding area 112 can be in close contact with the tab, thereby improving the welding quality between the welding area 112 and the tab.

[0068] Figure 7 The schematic diagram of the structure of the first anti-adhesion area and the welding area provided by an exemplary embodiment of the present application. Figure 7As shown, there is no overlapping part in the projections of the first anti-sticking area 111 and the welding area 112 on the projection plane (which can be understood as a plane parallel to one side of the second connecting portion 110). In this way, the first anti-sticking area 111 can avoid the actual weld mark in the welding area 112, avoiding the interference between the anti-sticking structure in the first anti-sticking area 111 (such as the aforementioned pits, bumps, etc.) and the welding equipment (such as welding seat, welding teeth, etc.), thereby avoiding the increase of welding slag and splashing during the welding process, and effectively ensuring the safety of the battery cell.

[0069] like Figure 7 As shown, the projection of the first anti-adhesion area 111 on the projection surface surrounds the projection of the welding area 112 on the projection surface. In this way, the first anti-adhesion area 111 can play a role in isolating adjacent adapter sheets 10 and preventing adsorption in all areas outside the welding area 112, so that the gap between two adjacent adapter sheets 10 can be evenly distributed.

[0070] It should be understood that if the minimum distance between the projections of the first anti-adhesion area 111 and the welding area 112 on the projection surface is too small, then during the welding process, the anti-adhesion structure in the first anti-adhesion area 111 (such as the aforementioned pits, bumps, etc.) and the welding equipment (such as welding seats, welding teeth, etc.) are likely to interfere with each other, resulting in increased welding slag, splashing, and other problems during the welding process; therefore, the embodiment of the present application limits the minimum distance G between the projections of the first anti-adhesion area 111 and the welding area 112 on the projection surface to within the following range: G ≥ 1mm. In this way, the anti-adhesion structure in the first anti-adhesion area 111 can be prevented from interfering with the welding equipment, thereby preventing increased welding slag, splashing, and other situations during the welding process, and effectively ensuring the safety of the battery cell.

[0071] In one embodiment, the area covered by the first anti-adhesion area 111 is M, the area of ​​one side of the second connecting portion 110 provided with the first anti-adhesion area 111 is N, and M and N satisfy: M ≥ 30% N. In this way, the problem of unclear adsorption due to the small coverage area of ​​the first anti-adhesion area 111 can be avoided.

[0072] Combination Figure 1 and Figure 5 , a second anti-adhesion area 101 is provided on one side of the first connecting portion 100, and the second anti-adhesion area 101 and the first anti-adhesion area 111 are respectively located on two opposite sides of the adapter sheet 10. In this way, during the stacking of multiple adapter sheets 10, the first anti-adhesion area 111 and the second anti-adhesion area 101 provided on two opposite sides can respectively play an anti-adsorption role, and can further prevent the adjacent adapter sheets 10 from being sucked up.

[0073] It should be noted that the implementation mode and structure of the second anti-adhesion zone 101 are similar to the implementation mode and structure of the first anti-adhesion zone 111 , and reference may be made to the aforementioned introduction to the first anti-adhesion zone 111 .

[0074] In one embodiment, the second anti-adhesion area 101 and the first anti-adhesion area 111 may also be disposed on the same side surface of the adapter sheet 10 .

[0075] In one embodiment, the side of the first connecting portion 100 where the second anti-sticking area 101 is not provided can be used to connect the pole. In actual applications, the side where the second anti-sticking area 101 is not provided can be a smooth surface. In this way, the first connecting portion 100 can be in close contact with the pole, thereby improving the welding quality between the first connecting portion 100 and the pole.
