The tabs of the stacked cores in traditional turnover boxes are difficult to fix and are easily squeezed and deformed during transportation. In addition, the turnover boxes have poor sealing properties, and moisture intrusion can cause the assembly process to fail, affecting the performance of the finished batteries in the group.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0022] See also Figure 1-4A stacked core storage device includes a box body 1 with an opening upward, a cover body 2 covering the opening of the box body 1, two first opposite sides of the box body 1 are symmetrically provided with notches 11, the sheet-like stacked cores are horizontally stacked in the box body 1, the size of the box body 1 matches the size of the stacked cores, and the tabs at both ends of the stacked cores are placed in the notches 11, the cover body 2 includes a top cover 21, and end plates 22 fixed on the two first opposite sides of the top cover 21, the end plates 22 are clamped on the outer wall of the box body 1, and when the cover is closed, a space for placing the tabs is formed between the end plates 22 and the ends of the stacked cores, so as to avoid the tabs from being squeezed during transportation. A pair of teeth 14 are provided on the inner side of the notch 11, and an isolating member 3 for isolating the upper and lower stacked cores is clamped on the teeth 14, and the isolating member 3 is a C-shaped plate sleeved on the teeth 14, and the two extended ends of the C-shaped plate extend horizontally to support the upper stacked core and isolate the lower stacked core. In other embodiments, the isolating member 3 may also be configured as a partition, with both ends overlapped on the tooth portion 14 respectively, to achieve isolation of the upper and lower stacked cores.

[0023] Furthermore, the upper edges of the inner walls of the two second opposite sides of the box body 1 are inclined outward to form a wedge-shaped structure 12; the second opposite sides of the top cover 21 are in contact with the second opposite sides of the box body 1, and the second opposite sides of the top cover 21 have an inverted blunt structure 211 that matches the wedge-shaped structure 12. Due to the gravity of the box body 1, the inverted blunt structure 211 is pressed on the wedge-shaped structure 12, thereby better achieving the sealing of the box body 1 and the cover body 2.

[0024] Furthermore, the inner wall of the second opposite side of the box body 1 is provided with a receiving cavity 13 for easy access. In order to better fix the stacked core, the size of the box body 1 matches the size of the stacked core, and there is no extra space. The existence of the receiving cavity 13 makes it more convenient to put in the stacked core.

[0025] Furthermore, the accommodating cavity 13 is symmetrically arranged on two inner walls of the box body 1, and its size can accommodate an adult's finger.

[0026] Furthermore, the bottom surface of the top cover 21 abuts against the upper edge of the slot 11 , and the width of the end plate 22 is greater than the width of the slot 11 to improve the sealing performance of the storage device.

[0027] Furthermore, the isolating member 3 is made of insulating material to avoid mutual influence between adjacent stacked cores during measurement.

[0028] When the utility model is used, first take a stacked core, clamp the middle part of the stacked core with the index finger and thumb, and put it into the box body 1 in a horizontal state, then respectively sleeve a C-shaped plate on the teeth 14 of the corresponding height at both ends of the box body 1, and then stack another stacked core on the C-shaped partition, and then sleeve the C-shaped plate on the teeth 14 of the higher layer, repeat the above steps until all the stacked cores are placed in the box body, and then cover the cover body 2, and the pole ears of all the stacked cores are accommodated in the accommodating space inside the end plate 22.
