Zinc-air batteries, as the master of metal-air batteries, have been widely used in many fields. Especially in China, the storage of zinc ranks first in the world, which has established the status of zinc-air batteries in domestic metal-air batteries. In fact, in our lives, small and micro zinc-air batteries are already very mature products.
What are the advantages of using the zinc air battery?
What are the reasons for choosing a zinc-air battery?
What are the current advantages of zinc-air batteries?
Since the zinc on the negative electrode only contacts OH- in the electrolyte and oxygen in the air during the working process of the zinc air battery, a chemical reaction occurs, so during the entire discharge process, no substances that pollute the atmosphere will be produced. In addition, zinc-air batteries are also known for their energy density, and their power generation per kilogram can reach 0.3KWH, which is twice as high as that of lithium batteries. That is to say, although the weight is only half of the lithium battery, the cruising range of the zinc-air battery is twice that of the lithium battery, and the increase of the storage capacity will not make the zinc-air battery more prone to explosion.
Environmental protection and pollution-free: The zinc-air battery has abandoned the toxic substances such as lead and mercury in the traditional battery. The positive electrode of the battery uses activated carbon and copper mesh, and the negative electrode uses metal zinc. No toxic substances are used, and it is easy to recycle.
Good safety performance: zinc-air batteries can effectively prevent fire or explosion caused by leakage and short circuit. Even if the outside encounters open flame, short circuit, puncture, impact, etc., it will not burn or explode. Zinc has no corrosive effect, and can be completely sealed and maintenance-free, and will not cause harm and danger to the human body.
1. Large specific energy: The theoretical specific energy of zinc-air battery can reach 1350Wh/kg, the specific energy of zinc-air battery is 4 to 6 times that of lead-acid battery, and it is 1 times larger than that of lithium-ion battery. The maximum range of an electric vehicle can reach 400km, while the general range of the same car with the same quality of lead-acid battery is not more than 100km. After the use of zinc-air batteries, electric vehicles can significantly improve the driving range of vehicles.
2. Uniform charge and discharge: The zinc-air batteries in groups have good consistency, and there is no uneven charge and discharge of other types of batteries. Deep discharge is allowed, and the capacity of the battery is not affected by discharge intensity and temperature. It can work normally in the temperature range of -20 ~ 80 ℃. zinc-air batteries can be completely sealed and maintenance-free, which is convenient for battery energy management. The voltage of the zinc electrode is stable, and the voltage change is small during discharge.
