Air battery

　　The air battery is a type of chemical battery. The structure of the structure is similar to the dry battery. The difference is that its oxidant is taken from the oxygen in the air. The air battery is classified as follows:

　　Zinc Air Battery (Zinc Air Battery)

　　Use activated carbon to absorb oxygen or pure oxygen in the air as a positive active substance, with zinc as the negative electrode, a original battery with ammonium chloride or harsh alkali solution as an electrolyte, which is called zinc oxygen battery. A zinc air battery divided into two systems of neutral and alkaline systems, which are represented by letters A and P, and then use numbers to represent the battery model. The charging process of zinc and air batteries is very slow. To solve this problem, the negative electleral zinc plates or zinc particles of zinc air batteries are usually oxidized into zinc oxide. Methods to fully update zinc air electricity.

　　Lithium air battery

　　Lithium -air batteries are not new concepts. Because the oxygen in the air is used as active substances on the positive electrode, the theoretical capacity density of the positive pole is unlimited and can increase the capacity. In addition, if the negative electrode uses metal lithium, the theoretical capacity will be increased by one level than lithium ion charging batteries.

　　However, the reason for lithium-air batteries has not been popularized so far. The reason is that it has fatal defects, that is, the solid reaction generates lithium oxide (li2O) will accumulate in the positive electrode, which is blocked by the contact between the electrolyte and the air, which will cause discharge to stop; Japan’s’s The research institute has overcome this difficulty, but it may take 10 years to achieve commercial use.

　　Aluminum air battery

　　Aluminum air batteries are a new type of battery used as aluminum and air as the battery material. It is a powerless, long -term, stable and reliable power supply, and a battery that is very friendly to the environment. The structure of the battery and the raw materials used can be changed according to different practical environments and requirements. It has great adaptability. It can be used for both land and deep sea. Signal battery is a very powerful battery with a very broad application prospect.

　　The chemical reactions of aluminum -air batteries are similar to zinc air batteries. Aluminum -air batteries are based on high -purity aluminum AL (99.99%aluminum) as the positive electrode and oxygen as the negative electrode. Essence Oxygen in the air is used to generate chemical reactions during battery discharge. The action of aluminum and oxygen is converted into alumina. The progress of aluminum -air batteries is very rapid. It has achieved good results in the application of EV (pure electric vehicles) and is a very promising air battery.
