Technical Field

[0001] This utility model relates to the field of battery cell blister packaging technology, specifically to a recyclable packaging structure for battery cell cover plates. Background Technology

[0002] Lithium batteries have advantages such as high energy density, light weight, small size, long cycle life, low self-discharge rate, no memory effect, and low environmental pollution. They are currently a hot topic in energy storage technology research in various countries. When handling or transporting battery cells, they need to be placed in a suitable packaging box to prevent the cells from sliding, colliding, or falling, which could damage the cell structure and appearance, or even cause safety accidents such as short circuits.

[0003] However, existing conventional battery cell packaging boxes do not adequately consider the stacking of blister packs. Due to the lack of foolproof structures, when workers stack blister packs, the battery cells on the lower blister packs are easily crushed by the upper blister packs, leading to an increased battery cell loss rate. In view of the above shortcomings, it is necessary to design a reusable packaging structure for battery cell covers. Utility Model Content

[0004] The purpose of this invention is to provide a recyclable packaging structure for battery cell cover plates to solve the problems mentioned in the background art.
