[0005] In the battery cell tray of this application embodiment, the positive terminal is disposed close to the first side wall, and the negative terminal is disposed close to the second side wall, thus placing the battery cell flat in the battery cell slot of the tray. The edge of the insulating film of the battery cell is usually distributed at the positive and negative terminals. A clearance groove is recessed at the intersection of the bottom wall of the slot and the first side wall, and a clearance groove is recessed at the intersection of the bottom wall of the slot and the second side wall. The clearance groove can prevent the battery cell tray from scratching and lifting the edge of the insulating film of the battery cell during storage and transportation, thereby reducing the problem of outer insulating film lifting and damage.
[0006] Optionally, the positive terminal of the battery cell includes a positive protrusion, and the first sidewall is provided with a first groove for accommodating at least a portion of the positive protrusion.

[0016] After the trays are stacked, the ventilation slot of the upper cell tray is connected to the cell slot and drying slot of the lower cell tray, which can form an airflow channel inside the cell tray, so that the moisture inside the cell tray can circulate and be absorbed by the desiccant.
[0017] Optionally, the cell tray further includes a boss connected to the main body. When multiple cell trays are stacked, the boss of the upper cell tray in any two adjacent cell trays is used to abut against the main body of the lower cell tray.
[0018] By setting up bosses, the height of the cell tray can be compensated, preventing the center from sinking.
[0019] Optionally, the cell tray further includes a peripheral portion connected to the outer periphery of the drying section, and at least a portion of the peripheral portion protrudes from the upper surface of the top wall.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0046] A battery cell may include a positive terminal, a negative terminal, and a side portion. For example, the side portion of a cylindrical battery cell can refer to the side surface of the cylindrical cell, which is usually curved. The positive terminal can refer to the end with the positive electrode, and the negative terminal can refer to the end with the negative electrode. The side portion of the battery cell is covered with an outer insulating film, which provides insulation between the cells when multiple cells are assembled together. The outer insulating film does not cover the end faces of the two ends (positive and negative terminals) of the cell. In related technologies, during the transportation of battery cells, they are placed upright in a battery tray. During this process, the tray comes into contact with the edge of the outer insulating film, which can easily cause the outer insulating film to warp or become damaged.
[0047] Please combine Figure 1 , Figure 2 Firstly, this application provides a battery cell tray 1, which includes a battery cell groove 11 for accommodating a battery cell 2. In one example, the battery cell groove 11 can be manufactured by stamping, casting, or other methods. The battery cell groove 11 includes a first side wall 111, a bottom wall 113, and a second side wall 115 connected in sequence. The first side wall 111 and the second side wall 115 are arranged opposite to each other. The first side wall 111 is positioned near the positive terminal 21 of the battery cell 2, and the second side wall 115 is positioned near the negative terminal 23 of the battery cell 2. It is easy to understand that the battery cell 2 may include a positive terminal 21 and a negative terminal 23 arranged opposite to each other. The positive terminal 21 is positioned near the first side wall 111, and the negative terminal 23 is positioned near the second side wall 115, thus placing the battery cell 2 flat in the tray. In other words, if the battery cell tray 1 is placed on a horizontal plane, the axial direction of the battery cell 2 placed in the battery cell groove 11 is parallel to the horizontal plane.
[0048] Please combine Figure 8 , Figure 9 as well as Figure 10 A recessed clearance groove 114 may be provided at the intersection of the bottom wall 113 of the tank and the first side wall 111. A recessed clearance groove 114 may also be provided at the intersection of the bottom wall 113 of the tank and the second side wall 115. The insulating film of the battery cell 2 is usually wound around the periphery of the battery cell 2, and the edges of the insulating film are usually distributed at the positive terminal 21 and the negative terminal 23 of the battery cell 2. Recessed clearance grooves 114 may be provided on the bottom wall 113 near the positive terminal 21 and the bottom wall 113 near the negative terminal 23, respectively. The recessed clearance grooves 114 can prevent the edges of the insulating film of the battery cell 2 from being scraped and lifted by the battery cell tray 1 during storage and transportation, thereby reducing the probability of the outer insulating film lifting and being damaged.
[0049] Please combine Figure 1 Multiple cell slots 11 can be arranged inside the cell tray 1, and the cell 2 is laid flat inside the cell tray 1.
[0050] In some embodiments, there are multiple cell slots 11, and at least some of the multiple cell slots 11 are arranged along a first direction. For example, when the cell tray 1 is constructed as a rectangular disk, the first direction is the width direction of the cell tray. Alternatively, the first sidewall 111 and the second sidewall 115 of the cell slot 11 are arranged in the first direction.
[0051] The cell tray 11 may further include a third sidewall 13 and a fourth sidewall 15 disposed opposite to each other, wherein both the third sidewall 13 and the fourth sidewall 15 are connected to the bottom wall 113 of the tray. The arrangement direction of the third sidewall 13 and the fourth sidewall 15 is the second direction. When the overall structure of the cell tray 1 is a rectangular disk, the second direction is the length direction of the cell tray. Both the first direction and the second direction are perpendicular to the thickness direction of the cell tray 1.
[0052] Please combine Figure 7 , Figure 8 , Figure 10 The positive terminal 21 of the battery cell 2 includes a positive electrode surface 211 and a positive electrode protrusion 213. The positive electrode protrusion 213 protrudes relative to the positive electrode surface 211 toward the side where the first sidewall 111 is located. The first sidewall 111 has a first groove 112 for accommodating at least a portion of the positive electrode protrusion 213. During transportation, the positive electrode protrusion 213 is prone to impact with the first sidewall 111, resulting in damage. The first groove 112 on the first sidewall 111 increases the distance between the first sidewall 111 and the positive electrode protrusion 213. Thus, during transportation, the sidewall of the first groove 112 opposite to the positive electrode protrusion 213 can maintain a distance from the positive electrode protrusion 213 at all times, and is less likely to rub against or collide with the positive electrode protrusion 213. This reduces the probability of the positive electrode protrusion 213 impacting the first sidewall 111, thereby reducing the risk of damage to the battery cell 2. In some examples, the positive electrode protrusion 213 may include the terminal post of the battery cell 2. In some examples, please refer to... Figure 10 The depth of the first groove 112 satisfies the following condition: when the positive electrode surface 211 abuts against the first side wall 111, there is a gap between the side wall of the first groove 112 opposite to the positive electrode protrusion 213 and the surface of the positive electrode protrusion 213 facing the first side wall 111, so that during transportation, the side wall of the first groove 112 opposite to the positive electrode protrusion 213 can always maintain a distance from the positive electrode protrusion 213.
[0053] Please combine Figure 9 , Figure 10 The first sidewall 111 is provided with a first guide slope 116 at the end opposite to the bottom wall 113 of the groove. As the first guide slope 116 moves away from the bottom wall 113 of the groove, the distance between the first guide slope 116 and the positive end 21 increases.
[0054] The second sidewall 115 is provided with a second guide slope 117 at one end away from the bottom wall 113 of the groove. As the second guide slope 117 moves away from the bottom wall 113 of the groove, the distance between the second guide slope 117 and the negative end 23 increases.
[0055] Please combine Figure 4 as well as Figure 5 By setting the first guide slope 116 and the second guide slope 117, the opening of the cell slot 11 is enlarged, making it easier to insert the cell 2. In addition, the opening of the cell slot 11 can have a large opening area, which makes it less likely to interfere with the cell 2. During transportation, the outer edge of the opening of the cell slot 11 is less likely to scratch the edge of the insulating film of the cell 2.
[0056] Please refer to Figure 1 The battery cell tray 1 includes a main body 10 and a drying part 30 connected to each other. The drying part 30 is located on the outer periphery of the main body 10. The main body 10 includes the battery cell tank 11. The drying part 30 is used to dry the battery cell 2.
[0057] Please combine Figure 6 Figure (a) in the middle Figure 6 Figure (b) in the middle and Figure 17 The drying unit 30 includes a drying tank 31 and a desiccant 33. The drying tank 31 is used to hold the desiccant 33, and the space inside the drying tank 31 is connected to the space inside the battery cell tank 11. In use, the desiccant 33 can be placed in the drying tank 31. Since the space inside the drying tank 31 is connected to the space inside the battery cell tank 11, the desiccant 33 can be used to dry the space inside the battery cell tank 11.
[0058] Please combine Figure 2 The first sidewall 111 and the second sidewall 115 are arranged opposite to each other along a first direction. The first sidewall 111 may have a notch 1101, and the second sidewall 115 may have a notch 1101. The notch 1101 is used to connect the cell tank 11 and the drying tank 31. This facilitates airflow along the first direction and drying.
[0059] The cell tank 11 also includes a third sidewall 13 and a fourth sidewall 15 disposed opposite each other along a second direction, the second direction forming an angle with the first direction. Both the third sidewall 13 and the fourth sidewall 15 are connected to the bottom wall 113 of the tank. The third sidewall 13 and the fourth sidewall 15 have a connecting groove 14, which connects the cell tank 11 to the drying tank 31. This facilitates airflow along the second direction and promotes drying.
[0060] The battery cell tray 1 includes a plurality of battery cell slots 11, and at least some of the internal spaces of the battery cell slots 11 are connected.
[0061] In one example, several cell tanks 11 are arranged along a first direction and are interconnected. Specifically, the sidewalls (e.g., the first sidewall 111 and the second sidewall 115) between adjacent cell tanks 11 arranged along the first direction may have through holes or notches, thereby connecting the adjacent cell tanks 11. At least one drying tank 31 may be arranged along the first direction with the cell tanks 11, and the drying tank 31 and the cell tanks 11 may be interconnected. Please refer to... Figure 2 , Figure 2 In the middle, the second side wall 115 has a notch 1101, thereby connecting the drying tank 31 and the cell tank 11.
[0062] In one example, several cell tanks 11 are arranged along a second direction and are interconnected. Specifically, a through hole may be formed in the sidewall between two adjacent cell tanks 11 arranged along the second direction. At least one drying tank 31 may be arranged along the second direction with the cell tanks 11, and the drying tank 31 may be connected to the cell tanks 11. For example, please refer to... Figure 2 The third sidewall 13 and the fourth sidewall 15 may each be provided with a connecting groove 14, which facilitates manual or equipment handling and is used to connect the drying tank 31.
[0063] Please combine Figure 12 , Figure 13 Figure (a) in the middle Figure 13 In Figure (b), along the thickness direction of the cell tray 1, the main body 10 includes a top wall 118 and a bottom wall 119. The top wall 118 is provided with the cell slot 11, and the cell can be placed into the cell slot 11 from one side of the top wall 118. The bottom wall 119 is provided with the ventilation slot 1191, and the ventilation slot 1191 is spaced apart from the cell slot 11.
[0064] Please combine Figure 11 , Figure 13 Figure (a) in the middle Figure 13 In Figure (b), the bottom wall 119 of the cell tray 1 is provided with a ventilation groove 1191, which can be a long strip-shaped concave structure provided in the bottom wall 119.
[0065] When multiple battery cell trays 1 are stacked, in any two adjacent battery cell trays 1, the vent 1191 of the upper battery cell tray 1 is connected to the battery cell vent 11 of the lower battery cell tray 1.
[0066] When multiple battery cell trays 1 are stacked, in any two adjacent battery cell trays 1, the ventilation slot 1191 of the upper battery cell tray 1 is connected to the drying slot 31 of the lower battery cell tray 1.
[0067] Multiple cell trays 1 are stacked in their thickness direction. The thickness direction of the cell trays 1 can be perpendicular to the arrangement direction of the first sidewall 111 and the second sidewall 115. In any two adjacent cell trays 1, the venting groove 1191 of the upper cell tray 1 can communicate with the cell groove 11 of the lower cell tray 1, and the venting groove 1191 of the upper cell tray 1 can communicate with the drying groove 31 of the lower cell tray 1. In one example, when multiple cell trays 1 are stacked in their thickness direction, in two adjacent cell trays, the bottom wall of the upper cell tray 1 contacts and engages with the top wall of the lower cell tray 1. A venting groove 1191 is provided on the bottom wall 119, and the venting groove 1191 of the upper cell tray 1 can communicate with the cell groove 11 and drying groove 31 of the lower cell tray 1.
[0068] After the trays are stacked, the ventilation slot 1191 of the upper cell tray 1 is connected to the cell slot 11 and drying slot 31 of the lower cell tray 1, which can form an airflow channel inside the cell tray 1, so that the moisture inside the cell tray 1 can circulate and be absorbed by the desiccant 33.
[0069] Please combine Figure 14 Figure (a) in the middle Figure 14 Figure (b) in the middle Figure 15 Figure (a) in the middle Figure 15 Figure (b) in the middle and Figure 16 The cell tray 1 also includes a boss 1193, which is connected to the main body 10. Specifically, the boss 1193 can be disposed on the bottom wall 119 of the main body 10. When multiple cell trays 1 are stacked, in any two adjacent cell trays 1, the boss 1193 of the upper cell tray 1 is used to abut against the main body 10 of the lower cell tray 1, specifically abut against the top wall 118 of the lower cell tray 1.
[0070] Because the support area in the middle of the battery cell tray 1 is relatively small, when multiple battery cell trays 1 are stacked in their thickness direction, a central depression can easily occur. This can affect the automated processing of the packaging equipment and the safety of the battery cells during transportation. In this embodiment, a protrusion 1193 is provided to compensate for the height of the battery cell tray 1, preventing the central depression. The height of the protrusion 1193 can range from 0.3mm to 3mm, for example, 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.3mm, 1.5mm, 2.3mm, 2.5mm, 2.8mm, or 3mm. After the trays are stacked, the compression compensation protrusion 1193 is supported at the main body 10 of the next battery cell tray 1, providing support force compensation.
[0071] The boss 1193 can be configured in multiple ways, and multiple bosses 1193 can be provided in the middle area of the bottom wall 119.
[0072] Please combine Figure 1 , Figure 13 The battery cell tray 1 also includes a peripheral portion 50, which is connected to the outer periphery of the drying section 30, and at least a portion of the peripheral portion 50 protrudes from the upper surface of the top wall 118. In some examples, the peripheral portion 50 is arranged around the outer periphery of the drying section 30, and the top of the peripheral portion 50 forms a ring of protrusion around the top of the tray, which can protect the battery cell tank 11 provided on the top wall 118.
[0073] Please combine Figure 2 The peripheral portion 50 is recessed relative to the drying portion 30 on the side near the bottom wall 119 (or recessed towards the top wall of the cell tray 1), and forms a second groove 501 with the drying portion 30 that mates with the peripheral portion 50.
[0074] When multiple cell trays 1 are stacked, in any two adjacent cell trays 1, the second groove 501 of the upper cell tray 1 is used to engage with the periphery 50 of the lower cell tray 1.
[0075] The second groove 501 can be a recessed notch at the bottom of the tray, which can engage with the protrusion formed by the periphery 50 of the other cell tray 1 located below, and be snapped into place.
[0076] The battery cell tray 1 includes multiple corner structures located on the outer periphery of the peripheral portion 50, with at least one corner structure differing from the others. A CCD positioning hole 105 may be provided in the drying section 30 near the corner structure to facilitate identification and positioning by automated equipment.
[0077] In one embodiment, please combine Figure 3 Figure (a) in the middle Figure 3 Figure (b) in the middle Figure 3 Figure (c) in the middle Figure 3 (d) diagram in the middle Figure 3 In Figure (e), the battery cell tray 1 can be square in shape. Three of the four corners of the battery cell tray 1 are rounded corners 101, and one is a chamfered corner 103. By setting the chamfered corner 103, the orientation of the battery cell tray 1 can be distinguished, so that the battery cell tray 1 can be stacked in a preset direction and prevent incorrect stacking orientation of the trays. The drying section 30 is provided with CCD positioning holes 105 near the four corner structures, which facilitates the identification and positioning of automated equipment.
[0078] In one embodiment, the drying section 30 may be provided with an arrow structure 104, which is used to indicate the visual direction, thereby facilitating personnel to determine the direction. In these embodiments, both the long and short sides of the battery cell tray 1 may be provided with drying tanks 31. The drying tanks 31 may be elongated, and multiple connecting notches may be provided between the drying tanks 31 and the battery cell tanks 11 to facilitate the absorption of moisture inside the battery cell tray 1 by the desiccant 33.
[0079] Please combine Figure 18 According to a second aspect of this disclosure, a battery cell transport device 3 is provided, comprising the aforementioned battery cell tray 1. This battery cell transport device possesses all the beneficial effects of the aforementioned battery cell tray 1, which will not be elaborated further herein.
