[0030] New energy vehicles are becoming increasingly popular, and lithium-ion batteries are the primary power batteries currently used in these vehicles. Therefore, the proper transportation of these batteries is crucial. Lithium-ion batteries must be protected from damage, crushing, and deformation during transportation. Long-distance transport of battery cells generally requires packaging, which requires a specific packaging structure. However, most current packaging structures make it difficult to remove the protective packaging panels from the corresponding boxes, which can be inconvenient for workers.

[0031] The primary functions of the battery cell packaging structure 1000 include protecting the battery cells 300 from the external environment, improving their safety and stability, and ensuring their performance and lifespan. First, the battery cell packaging structure 1000 effectively isolates the battery cells 300 from the external environment, reducing heat conduction and preventing damage to the battery cells 300 in high or low temperature environments. This protection is particularly important because both high and low temperatures can negatively impact the performance and lifespan of the battery cells 300. For example, high temperatures can cause overheating and damage to the battery cells 300 or electrolyte leakage, while low temperatures can significantly reduce battery capacity and discharge performance, or even render the battery inoperable. During production and transportation, the battery cell packaging structure 1000 also protects the lithium battery cells 300 from dust by bagging and sealing the carton 200. This measure is crucial for protecting the battery cells 300 from contamination by dust or smoke, as these contaminants can negatively impact product quality and even pose a threat to employee safety.

[0032] Based on this, see Figure 1 and Figure 2 The battery cell packaging box 100 provided in the embodiments of the present invention can effectively alleviate the aforementioned technical problem. The battery cell packaging box 100 facilitates the removal of the battery cells 300 without damaging them. The battery cell packaging box 100 is applied to a battery cell packaging structure 1000. The battery cell packaging structure 1000 having the battery cell packaging box 100 also has the same functions, and will not be described in detail here.

[0033] Figure 1 This is an exploded schematic diagram of the battery cell packaging structure 1000 provided in an embodiment of the present invention, as shown in FIG. Figure 1As shown, the battery cell packaging structure 1000 in this embodiment includes a carton 200 and a battery cell packaging box 100, with the battery cell packaging box 100 disposed within the carton 200. The battery cell packaging structure 1000 also includes battery cells 300, which are placed within the long receiving groove 110 of the battery cell packaging box 100, and the battery cells 300 are completely contained within the long receiving groove 110. Completely containing the battery cells 300 within the long receiving groove 110 of the battery cell packaging box 100 can protect the entire battery cell 300, preventing the battery cells 300 from being damaged by bumps and collisions during transportation. At the same time, the battery cell packaging box 100 is packaged in the carton 200. After the battery cells 300 are placed in the battery cell packaging box 100, the carton 200 is folded, packaged, and sealed, and then the product can be transported. The carton 200 can provide good protection, preventing the product from being affected by factors such as collisions, squeezing, moisture, and dust during storage in the transport box, thereby ensuring the integrity and quality of the product. Carton 200 packaging facilitates handling and transportation, reducing labor and logistics costs and improving transportation efficiency. Carton 200 is a recyclable and renewable packaging material that meets environmental and energy conservation requirements, helping to reduce resource waste and environmental pollution. Carton 200 is made from a wide variety of raw materials and has a low production cost. Compared to other packaging materials such as wooden boxes, carton 200 is less expensive. Furthermore, carton 200 is lightweight, reducing both packaging and transportation costs.

[0034] Furthermore, to protect the battery cells 300 during transportation, some soft, cushioning materials such as foam, foam plastic, and cotton may be placed inside the carton 200 to reduce the pressure caused by collisions during transportation and prevent damage to the battery cells 300. Of course, the battery cell packaging structure 1000 may also include other structures depending on specific transportation requirements, which are not limited here.

[0035] Figure 2 This is a schematic diagram of a battery packing box 100 provided in an embodiment of the present invention and containing a battery cell 300. Figure 1 and Figure 2 In this embodiment, the battery cell packaging box 100 is provided with a long accommodating groove 110 and a through groove 120. The long accommodating groove 110 is used to place the battery cell 300. The through groove 120 is perpendicular to the depth direction X of the long accommodating groove 110, and the through groove 120 passes through the long accommodating groove 110 along the thickness direction Y of the long accommodating groove 110. The through groove 120 is connected to the open end of the long accommodating groove 110. By providing the through groove 120, after the battery cell 300 is transported in the battery cell packaging box 100, the battery cell 300 can be conveniently removed from the through groove 120 without damaging the battery cell 300. Figure 1As shown, the battery cell packaging box 100 includes an upper end surface, a lower end surface, and a side surface connecting the upper and lower end surfaces, with the upper and lower end surfaces being parallel to each other. The battery cell packaging box 100 has a receiving groove extending from the upper end surface toward the lower end surface. In this embodiment, the depth direction X of the long receiving groove 110 refers to the direction of the linear distance between the upper and lower end surfaces. The thickness direction Y of the receiving groove is parallel to the upper end surface and perpendicular to the linear distance between the upper and lower end surfaces. The length direction Z of the receiving groove is perpendicular to both the depth direction X and the thickness direction Y.

[0036] In this embodiment, the cross-sectional shape of the long accommodating groove 110 in the plane formed by the X-direction and the Z-direction is a rectangle, and the long accommodating groove 110 is used to place the square battery cell 300. The width of the common square battery cell 300 is 10mm to 300mm, and the length is 100mm to 1500mm. In order to fully protect the battery cell 300 during transportation, the depth of the long accommodating groove 110 in this embodiment is 10mm to 300mm, and the length of the long accommodating groove 110 is 100mm to 1500mm. Of course, the depth, length and thickness of the long accommodating groove 110 are not limited. They are determined according to the size of the battery cell 300 that needs to be transported. As long as the battery cell 300 can be fully accommodated, it can protect the entire battery cell 300. The depth, length and thickness of the long accommodating groove 110 can be slightly greater than or equal to the size of the battery cell 300. The specific design size is not limited here. In addition, if a round battery cell 300 needs to be transported, the cross-sectional shape of the long receiving groove 110 in the plane formed by the X-direction and the Y-direction can be designed to be circular, and the overall shape of the long receiving groove 110 is cylindrical.

[0037] To facilitate the removal of battery cell 300, please continue to refer to Figure 1 and Figure 2 In this embodiment, the cross-section of the through-groove 120 is square. The cross-section here refers to the plane formed by the X-direction and the Z-direction. The square cross-section of the through-groove 120 increases the exposed area of ​​the battery cell 300, making it easier for operators to remove the battery cell 300. Of course, the cross-section of the through-groove 120 can also be designed in other shapes, such as circular or semicircular, as long as it facilitates the removal of the battery cell 300. The specific shape is not limited here.

[0038] If the through-groove 120 is opened too deep, most of the surface of the battery cell 300 may be exposed, which will affect the protection of the battery cell 300 by the battery cell packaging box 100 during transportation. However, if the through-groove 120 is opened too deep, it may be inconvenient for the operator to remove the battery cell 300. Therefore, the ratio of the depth of the through-groove 120 to the depth of the long accommodating groove 110 in this embodiment is greater than or equal to one-fifth, and less than or equal to one-half. Specifically, in this embodiment, the ratio of the depth of the through-groove 120 to the depth of the long accommodating groove 110 is one-third. Of course, it can also be other ratios such as one-fifth, one-quarter, one-half, etc., which can be selected according to actual conditions and are not limited here.

[0039] In order to transport multiple cells 300 at the same time, save transportation time and improve transportation efficiency, please refer to Figure 1 and Figure 2 In this embodiment, there are multiple long accommodating slots 110, which are arranged in parallel and at intervals; the through slots 120 pass through all the long accommodating slots 110. Specifically, the number of long accommodating slots 110 can be two, three, five, eight, ten, etc., depending on the specific transportation conditions and is not limited here.

[0040] To facilitate the removal of battery cell 300, please continue to refer to Figure 1 and Figure 2 , the number of through-grooves 120 in this embodiment is multiple, and the multiple through-grooves 120 are arranged in parallel and at intervals. Specifically, the number of through-grooves 120 in this embodiment is two, and the two through-grooves 120 are respectively arranged at positions close to both ends in the length direction of the long accommodating groove 110. The provision of two through-grooves 120 is just convenient for the operator to take out the battery cell 300 with both hands, preventing the battery cell 300 from being tilted and damaged during the removal process. Of course, the number of through-grooves 120 can also be three, four, etc. When multiple through-grooves 120 are provided, the length of the through-grooves 120 will be appropriately reduced to reduce the exposed area of ​​the battery cell 300 and protect the battery cell 300 during transportation.

[0041] Figure 3 This is a cross-sectional diagram of a battery pack 100 provided in an embodiment of the present invention. Figure 3, the long accommodating groove 110 in this embodiment is a blind groove. That is, the long accommodating groove 110 does not penetrate in the depth direction X and the length direction Z. The long accommodating groove 110 is a blind groove, which allows multiple sides of the placed battery cells 300 to be surrounded by the battery cell packaging box 100, thereby playing a strong protective role. In addition, since a cardboard box 200 is generally placed outside the battery cell packaging box 100, the long accommodating groove 110 can also be designed to penetrate in the depth direction X. Generally, some soft and cushioning materials such as foam are spread on the bottom of the carton 200, and then the battery cell packaging box 100 is placed in the carton 200, and the battery cell 300 is placed in the accommodating groove of the battery cell packaging box 100.

[0042] Pearl cotton, also known as polyethylene foam, is a new environmentally friendly packaging material. It's made from low-density polyethylene resin physically foamed to create countless independent cells with a non-crosslinked closed-cell structure. This material overcomes the shortcomings of conventional foam, such as brittleness, deformation, and poor resilience, and offers numerous advantages. Pearl cotton is waterproof and moisture-proof, and its closed-cell structure effectively prevents moisture penetration, protecting the battery cells 300 from humid environments. Its independent cell structure provides excellent shock absorption, absorbing impact and protecting the battery cells 300 from damage during transportation or storage. Pearl cotton also offers sound insulation, helping to reduce the impact of noise on the battery cells 300 and maintaining stable performance. Furthermore, its excellent thermal insulation and strong impact resistance help maintain a stable temperature within the battery cells 300 and protect their safety. Pearl cotton's excellent plasticity allows it to be customized to the specific shape and size of the battery cells 300, providing tight and comprehensive protection. Its strong toughness allows it to withstand external impacts, protecting the battery cells 300 from damage. Moreover, pearl cotton has good chemical resistance and can resist corrosion from a variety of chemicals, protecting the battery cell 300 from damage by chemicals. Furthermore, pearl cotton also meets environmental protection requirements and is easy to recycle and dispose of after use. Therefore, the battery cell packaging box 100 in this embodiment is made of pearl cotton.

[0043] Of course, the battery cell packaging box 100 can also be made of other materials such as aluminum-plastic film, depending on specific transportation requirements and is not limited here.

[0044] In summary, the battery cell packaging box 100 is provided with an elongated accommodating groove 110 and a through-groove 120. The elongated accommodating groove 110 is used to accommodate the battery cell 300. The through-groove 120 is perpendicular to the depth of the elongated accommodating groove 110 and extends through the elongated accommodating groove 110 along its thickness, communicating with the open end of the elongated accommodating groove 110. The provision of the through-groove 120 allows the battery cell 300 to be conveniently removed from the through-groove 120 without damaging the battery cell 300 after being transported within the battery cell packaging box 100.

[0045] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
