[0036] Reference Figure 1 , Figure 2 as well as Figure 4 As shown, the battery involved in the embodiments of this application has a height direction z, and the battery includes: a top cover assembly 100, a housing 200, an electrode assembly 300, and a connecting piece 400.

[0037] Specifically, the top cover assembly 100 includes a top cover 110 and an electrode post 120. The electrode post 120 is disposed on the top cover 110, and the top cover 110 has a first welding hole 111, which is spaced apart from the electrode post 120. The housing 200 is fitted onto the housing 200 to define a receiving cavity 210. The electrode post 120 protrudes from the top cover 110 at least partially along the height direction z toward the receiving cavity 210. The electrode assembly 300 is disposed within the receiving cavity 210 and includes a battery cell 310 and a tab 32. 0. The tab 320 is connected to one end of the cell 310 facing the pole post 120 along the height direction z; the connecting piece 400 includes a first connecting part 410 and a second connecting part 420 connected to the first connecting part 410. The first connecting part 410 is welded to the pole post 120. The second connecting part 420 is spaced apart from the top cover 110 and is at least partially exposed in the first welding hole 111. The tab 320 passes between the second connecting part 420 and the top cover 110 and is welded to the second connecting part 420 through the first welding hole 111.

[0038] It should be noted that the height direction z is Figure 1 as well as Figure 2 The direction indicated by z in the middle.

[0039] In the battery of this application, the electrode assembly 300 can be housed within the receiving cavity 210 to protect the electrode assembly 300 through the housing 200. Simultaneously, the tabs 320 of the electrode assembly 300 can be electrically connected to the terminals 120 of the top cover assembly 100 via the connecting piece 400. During this process, the terminals 120 can be welded to the first connecting portion 410, and the tabs 320 can be welded to the second connecting portion 420, thereby achieving the connection between the connecting piece 400, the tabs 320, and the terminals 120. Furthermore, during the welding process, the first connecting portion 410 and the terminals 120 can be connected first. Welding is performed at 20, and then the tab 320 is inserted between the second connecting part 420 and the top cover 110. The tab 320 is welded to the second connecting part 420 through the first welding hole 111. In this way, the tab 320 can be welded to the side of the second connecting part 420 away from the electrode assembly 300 along the height direction z. When the electrode assembly 300 and the top cover assembly 100 are assembled, there is no need to fold the tab 320. This reduces the space occupied by the tab 320 in the receiving cavity 210 in the height direction z, thereby improving the space utilization of the battery and increasing the energy density of the battery.

[0040] Reference Figure 3As shown, the tab 320 includes a transition portion 321 and a welding portion 322. The transition portion 321 extends along the height direction z, and both ends of the transition portion 321 along the height direction z are connected to the battery cell 310 and the welding portion 322, respectively. The welding portion 322 passes between the second connecting portion 420 and the top cover 110, and is welded to the second connecting portion 420 through the first welding hole 111.

[0041] In this embodiment, since the transition portion 321 extends along the height direction z and its two ends are connected to the battery cell 310 and the welding portion 322 respectively, the welding portion 322 can be located on the side of the second connecting portion 420 away from the electrode assembly 300 along the height direction z through the transition portion 321. This allows the welding portion 322 to pass between the second connecting portion 420 and the top cover 110, further facilitating welding of the welding portion 322 and the second connecting portion 420 through the first welding hole 111. Thus, the tab 320 can be welded on the side of the second connecting portion 420 away from the electrode assembly 300 along the height direction z, preventing the tab 320 from folding during casing assembly and reducing the space occupied by the tab 320 in the receiving cavity 210 in the height direction z.

[0042] Specifically, in this embodiment, when the welding part 322 passes between the second connecting part 420 and the top cover 110, the welding part 322 and the electrode assembly 300 are arranged parallel to one end face of the top cover 110 along the height direction z, so as to further reduce the space occupied by the electrode tab 320 in the receiving cavity 210 in the height direction z.

[0043] Continue to refer to Figure 3 As shown, in the height direction z, the second connecting part 420 is disposed closer to the top cover 110 than the first connecting part 410. The connecting piece 400 also includes a third connecting part 430. The two ends of the third connecting part 430 are respectively connected to the first connecting part 410 and the second connecting part 420, and the third connecting part 430 is bent from the first connecting part 410 toward the second connecting part 420 along the height direction z.

[0044] In this embodiment, to improve the stability of the electrical connection between the electrode post 120 and the electrode assembly 300, the electrode post 120 protrudes at least partially from the top cover 110 along the height direction z toward the receiving cavity 210. Since the electrode tab 320 and the second connecting portion 420 are welded through the first welding hole 111, when the second connecting portion 420 is positioned closer to the top cover 110 than the first connecting portion 410, the welding requirements of the electrode post 120 and the electrode tab 320 can be simultaneously met. Furthermore, due to the two... The first connecting part 410 and the second connecting part 420 are respectively connected to the third connecting part 430, and the third connecting part 430 is bent from the first connecting part 410 toward the second connecting part 420 along the height direction z. In this way, the first connecting part 410 and the second connecting part 420 can be connected through the third connecting part 430, and the first connecting part 410 and the second connecting part 420 can be transitioned through the third connecting part 430, so that the second connecting part 420 can be set closer to the top cover 110 than the first connecting part 410.

[0045] Reference Figure 2 as well as Figure 4 As shown, the top cover assembly 100 also includes a first insulating member 130. The first insulating member 130 is disposed on the side of the top cover 110 facing the receiving cavity 210 along the height direction z, and the two sides of the first insulating member 130 along the height direction z are respectively connected to the top cover 110 and the tab 320. The first insulating member 130 is provided with a second welding hole 131, which communicates with the first welding hole 111.

[0046] In this embodiment, since the first insulating member 130 is disposed on the side of the top cover 110 facing the receiving cavity 210 along the height direction z, and the two sides of the first insulating member 130 along the height direction z are respectively connected to the top cover 110 and the electrode tab 320, the first insulating member 130 can insulate the top cover 110 and the electrode tab 320. At the same time, since the first insulating member 130 is provided with a second welding hole 131, which is connected to the first welding hole 111, the electrode tab 320 can be exposed at least partially in both the second welding hole 131 and the first welding hole 111, so that the electrode tab 320 and the second connecting part 420 can be welded through the second welding hole 131 and the first welding hole 111.

[0047] Specifically, the first insulating member 130 has adhesive layers on both sides along the height direction z, and the top cover 110 and the tab 320 are bonded to the first insulating member 130 through the adhesive layers.

[0048] In this embodiment, since both the top cover 110 and the tab 320 are bonded to the first insulating member 130 through an adhesive layer, the stability of the connection between the first insulating member 130 and the top cover 110 can be improved through the adhesive layer. At the same time, the tab 320, which passes between the second connecting part 420 and the first insulating member 130, can be fixed through the first insulating member 130, so as to facilitate the subsequent welding of the tab 320 and the second connecting part 420.

[0049] Specifically, refer to Figure 4 As shown, the top cover 110 has an adhesive groove 112 on the side facing the receiving cavity 210 along the height direction z. The first insulating member 130 is bonded to the adhesive groove 112 through the adhesive layer, so as to position the first insulating member 130 on the top cover 110 by means of the adhesive groove 112.

[0050] Continue to refer to Figure 4 As shown, the top cover assembly 100 also includes a second insulating member 140, which is connected to the top cover 110 along the height direction z towards the receiving cavity 210. A first welding hole 111 passes through the top cover 110 and the second insulating member 140 along the height direction z. The first insulating member 130 is connected to the second insulating member 140 and the tab 320 on both sides along the height direction z.

[0051] In this embodiment, since the second insulating member 140 is connected to the top cover 110 along the height direction z towards the receiving cavity 210, and the first insulating member 130 is connected to the second insulating member 140 and the tab 320 on both sides along the height direction z respectively, the second insulating member 140 can further insulate the tab 320 and the top cover 110, thereby improving the insulation performance between the electrode assembly 300 and the top cover 110. Furthermore, since the first welding hole 111 penetrates the top cover 110 and the second insulating member 140 along the height direction z, interference caused by the second insulating member 140 to the welding of the tab 320 can be avoided.

[0052] Reference Figure 2 As shown, the top cover assembly 100 also includes a first sealing element 150, which passes through both the first welding hole 111 and the second welding hole 131, and is sealed to the hole wall of the first welding hole 111 and the hole wall of the second welding hole 131.

[0053] In this embodiment, since the first sealing member 150 passes through both the first welding hole 111 and the second welding hole 131 and is sealed to the hole walls of the first welding hole 111 and the second welding hole 131, after the tab 320 is welded to the second connecting part 420, the first sealing member 150 can seal the first welding hole 111 and the second welding hole 131, preventing external dust and moisture from entering the battery through the first welding hole 111 and the second welding hole 131, thus avoiding damage to the electrode assembly 300 and improving the safety performance of the battery.

[0054] Specifically, in this embodiment, the first sealing element 150 is an elastic sealing element, which is interference-fitted with the hole wall of the first welding hole 111 and the hole wall of the second welding hole 131 to achieve sealing of the first welding hole 111 and the second welding hole 131.

[0055] Continue to refer to Figure 2 As shown, the top cover assembly 100 also includes a second seal 160, which passes through the first welding hole 111 and is disposed on the side of the first seal 150 away from the receiving cavity 210 along the height direction z, and the second seal 160 is sealed to the hole wall of the first welding hole 111.

[0056] In this embodiment, since the second sealing member 160 passes through the first welding hole 111 and is disposed on the side away from the receiving cavity 210 along the height direction z of the first sealing member 150, and the second sealing member 160 is sealed to the hole wall of the first welding hole 111, the first sealing member 150 can be covered by the second sealing member 160, so as to further seal the first welding hole 111 and the second welding hole 131 by the second sealing member 160, thereby improving the sealing performance of the receiving cavity 210.

[0057] Specifically, in this embodiment, the second sealing element 160 is a sealing cap, which is welded to the wall of the first welding hole 111 to seal the first sealing element 150 and improve the sealing performance of the first welding hole 111 and the second welding hole 131.

[0058] Reference Figure 4 As shown, the top cover assembly 100 also includes a plurality of limiting structures 170, which are spaced apart on the edge of the top cover 110. Each limiting structure 170 extends toward the receiving cavity 210 along the height direction z, and each limiting structure 170 abuts against the side surface of the battery cell 310.

[0059] In this embodiment, since multiple limiting structures 170 are spaced apart on the edge of the top cover 110, each limiting structure 170 extends toward the receiving cavity 210 along the height direction z, and each limiting structure 170 abuts against the side surface of the battery cell 310, when assembling the top cover assembly 100 and the electrode assembly 300, the electrode assembly 300 can be positioned between the multiple limiting structures 170 to confirm the connection relationship between the top cover assembly 100 and the electrode assembly 300. This facilitates the insertion of the tab 320 into a preset position between the second connecting portion 420 and the top cover 110, so as to facilitate welding of the tab 320 and the second connecting portion 420, thereby improving the stability of the connection relationship between the tab 320 and the second connecting portion 420, and further improving the stability of the connection relationship between the electrode assembly 300 and the top cover assembly 100.

[0060] Specifically, the electrode assembly 300 abuts against a limiting structure 170 at each of the four opposite corners of one end face of the top cover assembly 100 along the height direction z, and abuts against any number of limiting structures 170 at each edge excluding the four opposite corners, so as to ensure that the electrode assembly 300 can be limited between multiple limiting structures 170.

[0061] The electrical device involved in the embodiments of this application includes the battery described above.

[0062] In the power device of this application, since the battery of this application has a high space utilization rate, the battery of this application can have a high energy density, and thus the power device of this application can have a long battery life.
