Description

Technical Field

[0001] The utility model relates to the technical field of zinc-air batteries, in particular to a zinc-air battery with a filtering device. Background Art

[0002] The new air battery has the advantages of high specific energy, stable working voltage and almost no pollution, because the positive active material comes from oxygen in the air. However, since its electrolyte is generally an alkaline solution, it is well known that the hydroxide ions in the alkaline solution can easily react with the carbon dioxide in the air to produce carbonate substances, which makes the electrolyte lose its due function.

[0003] After searching, the publication number is CN204189923U, which discloses a zinc-air battery with a filtering device, including a zinc-air battery and a shell. The shell is internally provided with a filtered liquid pool, a desiccant chamber, a small fan installation position, a backup power supply installation position, a zinc-air battery installation position and an air duct.

[0004] In the process of realizing the utility model, the inventors found that at least the following problems exist in the prior art and have not been solved: the air passes through the filter pool and the desiccant along the air duct, and the carbon dioxide, dust and moisture carried in the filtering process in the air are removed, providing a stable and continuous source of clean and dry oxygen for the zinc-air battery. However, during use, it is impossible to detect the carbon dioxide concentration in the treated air, and it is impossible to ensure that the carbon dioxide concentration in the treated air does not exceed the standard. Moreover, the filtrate in the filter pool will become saturated after long-term use, and it is easy to fail, and needs to be replaced regularly.

[0005] Therefore, we propose a zinc-air battery with a filtering device to solve the above problems. Utility Model Content
