Features of aluminum air batteries.solar powered generator for home

　　A, higher energy than energy, battery theory is 2290Wh/kg, which has actually reached 300 ~ 400Wh/kg. This value is much higher than the energy of various batteries today. Although the energy of the battery is equivalent to this, it is not safe to make it unable to use it for power batteries.

　　B. The characteristics of 50 ~ 200W/KG are obviously determined by the oxygen electrode. Because the working potential of oxygen electrode is far from its thermodynamic balance potential. Its exchange current density is small, and the battery is very polarized during discharge. The ratio of hydroxide fuel cells is not high, the reason is that the reason is

　　C. The service life reaches 3 to 4 years. This also depends on the working life of the oxygen electrode, because the aluminum electrode can be continuously replaced.

　　D. Non -toxic, no harmful gases, no pollution environment. Battery reaction consumes aluminum, oxygen and water to generate. The latter is the Yosheng sediment that is currently used for sewage treatment.

　　E. It is designed as an electrolyte circulation and a non -circulating form. It is convenient for designing different uses;

　　F. The aluminum resources are abundant, and the working principle of the working principle of the aluminum -air battery is the negative electrode of the aluminum -air battery is aluminum alloy. It is continuously consumed and generated during the battery discharge; When the battery discharge, the oxygen (air) of the electrode is generated by electrochemical reactions; the electrolyte can be divided into two types, one is the neutral junior solution [or water or seawater), and the other is the alkaline junior solution. Will aluminum -air batteries replacing lithium batteries? At present, aluminum batteries that can replace lithium batteries are still in the trial stage and are not put into commercial use. Therefore, in general, whether aluminum air batteries will replace lithium batteries, it is still unknown, so let's take a look at what problems will be encountered by aluminum -air batteries to replace lithium batteries. In terms of battery life, aluminum -air batteries are indeed a breakthrough compared to lithium batteries. However, because the anode corrosion of aluminum air batteries will produce hydrogen during discharge, this will not only cause the loss of the anode material, but also increase the internal loss of the battery. In addition, the aluminum air battery consume Reinstallation of aluminum, etc., has greatly hindered the commercial development of aluminum -air batteries. And in terms of vehicle applications, aluminum -air batteries are still unknown, and they are not even comparable to hydrogen fuel cells.
