Will aluminum-air batteries replace lithium batteries in the future?

Will aluminum-air batteries replace lithium batteries? Introduction to aluminum-air batteries The chemical reaction of aluminum-air batteries is similar to that of zinc-air batteries. The aluminum-air battery uses high-purity aluminum (containing 99.99% aluminum) as the negative electrode, oxygen as the positive electrode, and potassium hydroxide (KOH) or sodium hydroxide (NaOH) as the electrolyte. Aluminum absorbs oxygen from the air, and a chemical reaction occurs when the battery discharges to convert aluminum and oxygen into alumina. Will aluminum-air batteries replace lithium batteries? Aluminum batteries that can replace lithium batteries are still in the experimental stage and have not yet been put into commercial use. So in general, it is not clear whether aluminum-air batteries will replace lithium batteries, so let us see what problems aluminum-air batteries will encounter when replacing lithium batteries. In terms of battery life, aluminum-air batteries are a real breakthrough compared with lithium batteries. However, because aluminum-air batteries will undergo anode corrosion during the discharge process, the presence of hydrogen will not only cause the loss of anode data, but also increase the internal loss of the battery. In addition, aluminum-air batteries consume aluminum, and aluminum must be reinstalled when the battery life ends, which greatly hinders the commercialization of aluminum-air batteries. In terms of airborne applications, aluminum-air batteries are still an unknown, even inferior to hydrogen fuel-powered batteries. Analysis of the reasons why aluminum-air batteries cannot replace lithium batteries 1. Importantly used for emergency power. Aluminum-air batteries are not traditional batteries that repeatedly store electrical energy, but are chemical reaction devices that release electrical energy. He said that its working principle is to release energy by oxidizing the active metals in the water, and then output in the form of electricity through the electrolyte and special electrode data. Generally speaking, for aluminum-air batteries, the active metal is aluminum, similar to zinc-air batteries and magnesium-air batteries, but based on the activity of the metal (the strength of the oxidation reaction in water or air), the use of electrolyte and other auxiliary information Slightly different. 'Just add water' essentially uses aluminum, not water, just to extend the life of the battery. Chen Tao told reporters that during the working process of the battery, there is a stable output power flow, and the metal aluminum is also in a stable oxidation and consumption flow. Aluminum hydroxide appears, and the electrical energy uses the chemical energy of aluminum as a condition. A 100 kg aluminum-air battery can store enough energy to carry 3000 kilometers. After 3000 kilometers, the life of the battery is over and must be reinstalled to make up for the metal aluminum. According to analysis, aluminum-air batteries appeared as early as the 1960s. But so far, its discussion is still at the theoretical stage, and there are not many practical applications. Important domestic research on emergency power supplies; while abroad, scientists are either studying certain electrode data or studying special-purpose battery systems, all trying to use aluminum-air battery technology to break through. 2. At present, the biggest bottleneck in safety hazard inspection is the use of aluminum-air batteries. Chen Tao believes that in addition to the inconvenience of storing electric energy, it also has many inconveniences compared with other gas fuel power batteries, such as hydrogen fuel power batteries. Convenience. Secondly, there are many secondary reactions, and the reaction process is not easy to control. Some reaction products prevent the reaction from proceeding to a certain extent, releasing a large amount of heat, and there are also flammable and explosive gases. Aluminum seems to play a more important role in the development of electric vehicles. An interesting phenomenon is that the battery life of Tesla electric vehicles in the United States can be increased to 300-400 kilometers. It is important to use nickel-cobalt-aluminum terrain data, while my country's electric vehicles use nickel-cobalt-manganese. The difference between these two metals is aluminum. The aluminum data used by Tesla is mainly used for batteries that can be stored repeatedly. The effect of this is to increase the energy density of the battery, so that the same amount of battery can store more energy, allowing the car to travel longer. Chen Tao believes that only from this perspective can a real breakthrough be made. However, the security risks that this brings need to be further studied in practice.
