[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution: a reusable packaging box for battery cells, comprising a box body 1 with a side panel and a battery cell packaging structure. The box body 1 includes a side panel 11, a box cover 12, and a base 13. The battery cell packaging structure is disposed inside the box body 1. The battery cell packaging structure includes multiple stacked blister tray bodies 2. The multiple blister tray bodies 2 are stacked on the base 13. Each blister tray body 2 has two spaced cavities on its upper surface. Multiple partitions 21 arranged along the length of the blister tray body 2 are fixedly installed in the cavities, dividing the cavities into multiple large cavities. The small, identical receiving slot 22 has a material picking slot 23 on the partition 21, which makes it easy for operators to pick up the battery cell shell with their fingers. Both ends of the receiving slot 22 are equipped with protrusions 24, and there are relief slots 25 on both sides of the protrusions 24 in the receiving slot 22. By setting four relief slots 25 in the receiving slot 22, since the rectangular battery cell shell has sharp corners, and the sharp corners are easily damaged by collision, the relief slots 25 can give way to the sharp corners of the battery cell shell, so that the battery cell shell does not come into contact with the sharp corners of the blister tray body 2, thereby avoiding collision and damage to the sharp corners of the battery cell shell when picking up and putting down the battery cell shell.

[0021] In this embodiment, the bottom of the receiving groove 22 is provided with a reinforcing strip 26, and the reinforcing strip 26 is distributed in a "+" shape. This reinforcing strip 26 can strengthen the receiving groove 22 and improve the overall stability of the blister tray body 2.

[0022] In this embodiment, a surrounding plate 11 is assembled between the box cover 12 and the base 13.
