Zinc air battery is an environmentally friendly battery with small size, large charge capacity, low mass, normal operation in a wide temperature range, no corrosion, and safe and reliable operation.
For zinc-air batteries, the air electrode is the core. The air electrode of the zinc-air battery is an ultra-thin electrode, which is in contact with both the electrolyte and the air during operation, and assumes the place of the three-phase reaction.
The charging process of zinc-air batteries is very slow. To solve this problem, the negative zinc plate or zinc particles of zinc-air batteries are oxidized to zinc oxide and fail. The zinc plate or zinc particles and electrolyte are usually replaced directly, making the zinc-air battery completely renewed.
The invention of the zinc air battery has a history of more than 100 years, and it was first applied to power sources such as railway signal lights. Compared with traditional batteries, the biggest feature of zinc-air batteries is green environmental protection.
