Description

Technical Field

[0001] The utility model relates to the field of zinc ion battery devices, in particular to a zinc ion battery device composed of a zinc anode plated with an in-situ gel electrolyte. Background Art

[0002] Zinc, as a negative electrode material, has the advantages of abundant reserves, low cost, and environmental friendliness. However, the zinc negative electrode is prone to form dendrites during the charge and discharge process, leading to battery short circuit and capacity decay. Therefore, researchers have improved the cycle stability and safety performance of the zinc negative electrode by optimizing the structure and composition of the zinc negative electrode, such as using nano-sizing and alloying. The electrolyte is the medium for ion transport in zinc batteries and is crucial to the performance and safety of the battery. Traditional zinc batteries use aqueous solutions as electrolytes, but there is a risk of corrosion and leakage. Therefore, researchers have developed new electrolyte materials such as solid electrolytes and gel electrolytes to improve the safety and stability of zinc batteries.

[0003] The Chinese utility model patent with authorization number CN219425000U provides a power battery for quick disassembly and assembly, which includes a battery box, a battery pack and a locking assembly. The battery pack includes multiple first battery cells and multiple second battery cells. The multiple first battery cells are embedded in the battery box, and the multiple second battery cells are slidably connected to the battery box along the width direction of the battery box. When the multiple second battery cells slide to the first position, the projections of the multiple first battery cells and the multiple second battery cells along the length direction of the battery box completely overlap. When the multiple second battery cells slide to the second position, the projections of the multiple first battery cells and the multiple second battery cells along the length direction of the battery box partially overlap; the locking assembly is detachably connected to the battery box; it solves the problem that the existing battery pack is embedded in the outer shell and is difficult to remove. At the same time, the multiple battery cells in the battery pack are fixedly connected, so that the disassembly of the battery cells is time-consuming and labor-intensive.

[0004] However, the quick-assembly and disassembly power battery provided by the above patent has the problem of shortening the battery life and being flammable and explosive during high-temperature operation. Therefore, a solution is needed to improve this problem. Utility Model Content
