[0017] In any of the above technical solutions, further, the shell includes an upper shell, a lower shell and a top cover; wherein the upper shell is a structure that is hollow inside and open at the top and bottom, and the lower shell is a structure that is hollow inside and open at the top;

It can be seen that it is precisely because the liquid replenishment through hole is designed into the above structure that the liquid replenishment speed is accelerated.

[0023] In addition, a buffer groove is designed below the injection hole. After the shell is inverted, the electrolyte enters the buffer groove first, thereby ensuring the timeliness of the liquid supply.

[0024] In addition, the top of the supporting column of the partition member is extended into the buffer groove to play a role in guiding flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Refer to the following Figures 1 to 13 A battery cell casing and a battery cell capable of cyclic liquid replenishment according to some embodiments of the present application are described.

[0047] Embodiment 1

[0048] See also Figures 1 to 9 As shown, an embodiment of the present application provides a battery cell shell 1 that can be circulated and replenished with liquid, comprising: a shell 1 and a partition member 2; wherein the partition member 2 is arranged inside the shell 1, and along the height direction of the shell 1 and from top to bottom, the partition member 2 divides the interior of the shell 1 into a pole core area 14 and a liquid storage area 15; the partition member 2 is formed with a liquid replenishment through hole 211, and the liquid replenishment through hole 211 is respectively connected to the pole core area 14 and the liquid storage area 15.

[0049] Based on the structure described above, it can be known that the battery cell shell 1 with circulatory liquid replenishment provided by the present application has a liquid storage area 15 formed therein. When the pole core placed in the pole core area 14 lacks electrolyte, the battery shell 1 can be rotated and inverted as a whole, so that the liquid storage area 15 originally at the bottom is converted to the top, and the pole core area 14 originally at the top is converted to the bottom, so that the electrolyte in the liquid storage area 15 enters the pole core area 14 through the liquid replenishment through hole 211 to infiltrate the pole core. When the pole core is fully infiltrated, the battery shell 1 is flipped over to its original state again. Correspondingly, the pole core area 14 is located at the top again, and the liquid storage area 15 is located at the bottom again, and the excess electrolyte flows from the liquid replenishment through hole 211 to the liquid storage area 15 below, avoiding the immersion of the electrolyte in the pole core, thereby improving the performance of the battery cell, and the above-mentioned liquid replenishment operation can be repeated, that is, the pole core can be replenished multiple times, and the operation is simple, convenient, and time-saving and labor-saving.

[0050] In this embodiment, preferably, Fig. 9 As shown, along the height direction of the housing 1 and from top to bottom, the liquid replenishing through hole 211 is tapered.

[0051] According to the structure described above, it can be known that when the electrolyte is freed from the liquid storage area 15 to the pole core area 14, the freeing speed can be accelerated; when the liquid replenishment is completed, the electrolyte can be accelerated when it returns from the pole core area 14 to the liquid storage area 15. It can be seen that it is precisely because the liquid replenishment through hole 211 is designed into the above structure that the liquid replenishment speed is accelerated.

[0052] Further, preferably, the fluid replenishing through hole 211 is a conical hole. Of course, it is not limited to this. The fluid replenishing through hole 211 can also be in the shape of a round celestial body or a square celestial body, etc., and can also be designed according to actual needs.

[0053] It should be noted that the structure of the liquid replenishing through hole 211 is not limited to the above. For example, the liquid replenishing through hole 211 may also be a structure with the same thickness at the top and the bottom.

[0054] In this embodiment, preferably, Figure 6 and Fig. 9 As shown, a cache groove 212 is formed on one side of the partition member 2 close to the liquid storage area 15, and along the height direction of the shell 1, the cache groove 212 is arranged below the liquid replenishment through hole 211 and is connected to the bottom of the liquid replenishment through hole 211, and the top of the liquid replenishment through hole 211 passes through the top of the partition member 2.

[0055] According to the structure described above, after the housing 1 is turned upside down, the electrolyte first enters the buffer groove 212, thereby ensuring the timeliness of the liquid supply.

[0056] Further, preferably, there are multiple cache grooves 212 , and each cache groove 212 is equipped with multiple liquid replenishment through holes 211 , and the multiple liquid replenishment through holes 211 are evenly arranged.

[0057] Furthermore, preferably, the plurality of buffer grooves 212 are evenly arranged to improve the uniformity of wetting of the pole core. Of course, the present invention is not limited thereto and can also be designed according to actual needs.

[0058] In this embodiment, preferably, Figure 4 As shown, along the height direction of the shell 1, the partition member 2 is arranged close to the bottom of the shell 1 to ensure that the pole core area 14 has sufficient space.

[0059] Further, preferably, Figure 4 As shown, along the height direction of the shell 1, the liquid storage area 15 occupies 1 / 5 of the height dimension of the shell 1, and correspondingly, the pole core area 14 occupies 4 / 5 of the height dimension of the shell 1, while ensuring sufficient liquid storage capacity, it can avoid occupying too much space in the pole core area 14.

[0060] In this embodiment, preferably, Figures 4 to 11 As shown, the partition member 2 includes a partition plate 21 and a support column 22 connected to each other; wherein the support column 22 is disposed at the bottom of the partition plate 21, supported on the bottom of the housing 1, and connected to the bottom of the housing 1;

[0061] The entire circumferential outer wall of the partition plate 21 is arranged against the entire circumferential inner wall of the shell 1 to divide the interior of the shell 1 into a pole core area 14 and a liquid storage area 15, and preferably, along the height direction of the shell 1, that is, the height direction of the support column 22 and the partition plate 21 and from top to bottom, the partition plate 21 is formed with liquid replenishment holes 211 and cache grooves 212 arranged in sequence.

[0062] According to the structure described above, the support column 22 plays the role of supporting the partition plate 21, and forms a certain space below the partition plate 21, namely the liquid storage area 15. In addition, the partition plate 21 can also play the role of supporting the pole core, and preferably, a mounting hole 213 is provided on the partition plate 21, which can be a hole with a smooth inner wall or a hole with an internal thread on the inner wall for locking the pole core, and is designed according to actual needs.

[0063] Further, preferably, Figure 6 and Fig. 9As shown, the top of the support column 22 extends into the cache groove 212, and along the height direction of the support column 22, the top of the support column 22 is connected to the inner wall of the cache groove 212, and the support column 22 plays a role of diversion. The electrolyte will flow into the cache groove 212 along the support column 22, and then flow into the pole core area 14 through the replenishment through hole 211. Especially when the electrolyte in the liquid storage area 15 is less, the role of the support column 22 is more obvious. When the electrolyte in the liquid storage area 15 is more, this diversion structure is not required. For example, the top of the support column 22 can be moved out of the cache groove 212. That is to say, along the height direction of the support column 22, the projections of the support column 22 and the cache groove 212 are staggered. The specific selection is based on actual needs.

[0064] Further, preferably, Figure 6 As shown, along the height direction of the support column 22 , its projection falls on the center of the cache groove 212 , and preferably, each cache groove 212 corresponds to a plurality of liquid replenishment holes 211 , and the plurality of liquid replenishment holes 211 are evenly arranged around the periphery of the support column 22 .

[0065] Further, preferably, the housing 1 is in a rectangular parallelepiped shape, and correspondingly, the partition plate 21 is a corresponding rectangular plate.

[0066] Further, preferably, Figure 6 and Fig. 9 As shown, there are multiple support columns 22 which are evenly arranged.

[0067] Further, preferably, the support column 22 and the partition plate 21 are an integrated structure. Of course, not limited to this, the two can also be connected by one or more of the methods of plugging, welding, gluing and bolts.

[0068] It should be noted that the structure of the partition member 2 is not limited to the above, and can also be designed according to actual needs. For example, the partition member 2 can only include the partition plate 21, removing the structure of the support column 22, and the partition plate 21 is connected to the shell 1 by welding, gluing or clamping.

[0069] In this embodiment, preferably, Fig.10 As shown, a mounting blind hole 121 is formed on the inner bottom wall of the housing 1 , and the support column 22 is inserted into the mounting blind hole 121 .

[0070] According to the structure described above, the support column 22 is inserted into the blind hole, and preferably, the two can be reinforced by welding, such as ultrasonic welding, so that the partition member 2 and the shell 1 are assembled more firmly and stably. Of course, it is not limited to this, and the support column 22 can also be connected to the bottom of the shell 1 without a connection relationship, but the aforementioned partition plate 21 can be connected to the inner wall of the shell 1 by welding, which is selected according to actual needs.

[0071] In this embodiment, preferably, Figures 1 to 3 As shown, the outer wall of the housing 1 is provided with an anti-slip member 3 .

[0072] According to the structure described above, when the robot grasps the battery cell, the anti-slip component 3 plays an anti-slip role.

[0073] Further, preferably, the anti-slip member 3 is arranged on the outer wall of the large surface formed by the long side and the high side of the shell 1, and preferably, the number of anti-slip members 3 is two, and they are respectively arranged on two relatively large surfaces. The manipulator generally contacts the two large surfaces of the aforementioned shell 1 to perform grasping. Of course, the number of anti-slip members 3 is not limited to this, and the number can also be one. In addition, the installation position of the anti-slip member 3 is not limited to this, and it depends on the number of contact surfaces between the manipulator and the shell 1.

[0074] Further, preferably, the anti-slip member 3 is a square plate, and is provided with a plurality of pits, holes or protruding structures, so as to play an anti-slip role.

[0075] Further, preferably, the material of the anti-slip member 3 can be metal, and the same material as the housing 1, to strengthen the housing 1. Of course, not limited to this, the material of the anti-slip member 3 can also be rubber, etc., specifically designed according to actual needs.

[0076] In this embodiment, preferably, Figures 1 to 3 , Fig.12 and Fig.13 As shown, the outer wall of the housing 1 is formed with a mounting groove 111, and the inner wall of the mounting groove 111 facing the opening thereof is formed with a clamping groove 112;

[0077] The anti-slip component 3 is installed in the installation groove 111 . The anti-slip component 3 is formed with a clamping protrusion, and the clamping protrusion is clamped in the clamping groove 112 .

[0078] According to the structure described above, the anti-slip component 3 is installed in the installation groove 111, and the snap-in protrusion thereon is snap-engaged in the snap-in groove 112 of the inner wall of the installation groove 111, which plays a double reinforcement role, making it difficult for the anti-slip component 3 to fall off the outer wall of the shell 1, and the structure is more reliable. In addition, the installation operation is simple and convenient, saving time and effort, and thus improving the assembly efficiency.

[0079] Of course, not limited to the above-mentioned installation method, the anti-slip component 3 can also be fixed to the outer wall of the shell 1 by gluing or welding, etc., and the design is specifically based on actual needs. In addition, the anti-slip component 3 is a component independent of the shell 1, and can therefore be processed and manufactured separately to avoid affecting the shell 1. Of course, not limited to this, the anti-slip component 3 can also be an integrated structure with the shell 1, that is, pits or protrusions are directly set on the shell 1, and the design is specifically based on actual needs.

[0080] Further, preferably, the depth of the slot 112 is greater than 1 / 3 of the wall thickness of the housing 1 . Of course, this is not limited to this and can be designed according to actual needs.
