Description

Technical Field

[0001] The utility model belongs to the technical field of metal fuels, and in particular relates to a zinc-air battery module. Background Art

[0002] Traditional batteries often contain some toxic substances and cause certain pollution to the environment. Zinc-air batteries have attracted widespread attention due to their stable discharge voltage, low price, high specific capacity, and environmental friendliness. They are expected to be widely used in the fields of electric vehicles and energy storage. Today, rechargeable zinc-air batteries are mainly divided into electrochemical charging and mechanical replacement charging. The working principle of mechanical replacement zinc-air batteries is that zinc is used as the negative electrode material and oxygen is used as the positive electrode material, and an oxidation-reduction reaction occurs in the medium of an alkaline electrolyte to release electrical energy.

[0003] At present, zinc-air batteries are still immature and have not been widely used. This is mainly because zinc-air batteries need to be in contact with air, which requires that the structural design of zinc-air batteries must ensure that oxygen can enter while the electrolyte does not leak out. At the same time, since the zinc sheet negative electrode and electrolyte materials are consumable materials, the structure of the zinc-air battery must be easy to disassemble and replace with new battery materials. Secondly, in order to facilitate large-scale production and use, its structure should be as small as possible. Finally, in order to make the battery have better performance, it should have better durability.

[0004] Mechanical zinc-air batteries are prone to structural damage due to frequent replacement, and the air electrode is not in smooth contact with the outside air, which affects the performance and life of the battery. In addition, the current mechanical zinc-air battery structure is relatively large, which is not conducive to its use in some small electronic products. Therefore, a zinc-air battery module is urgently needed to solve the above technical problems. Utility Model Content
