What are the advantages and disadvantages of zinc air batteries

Zinc-air battery uses activated carbon to adsorb oxygen or pure oxygen in the air as the positive electrode active material, zinc as the negative electrode, and ammonium chloride or caustic alkali solution as the electrolyte. Also known as zinc-oxygen battery. Zinc-air batteries, which are divided into two systems, neutral and alkaline, are represented by the letters A and P respectively, and then the number is used to represent the battery model. Advantages: small size, large charge capacity, small mass, can work normally in a wide temperature range, and no corrosion, safe and reliable work, low cost, etc. Features: 1) High specific energy, generally above 200Wh/kg; 2) It can work under high current density; 3) The material source is abundant and the cost is low. Disadvantages: 1) The structure of the air electrode is more complicated than the usual metal oxide electrode 2) The air electrode needs to be exposed to the air when it works, and the air electrode is porous, so it actually exposes the electrolyte to the air Therefore, the air battery cannot be made into a sealed battery, and the electrolyte will evaporate or be carbonated by carbon dioxide in the air, which limits the life of the battery. 3) As a secondary battery, zinc-air battery has a relatively low number of charge and discharge cycles.
