Will Aluminum Air batteries replace lithium-ion battery

Introduction of aluminum air battery the chemical reaction of Aluminum Air Battery is similar to that of Zinc–air battery. Aluminum air battery with high purity aluminum (containing 99.99% aluminum) for the negative electrode, oxygen for the positive electrode, potassium hydroxide or sodium hydroxide for electrolyte. Aluminum absorbs oxygen from the air, and a chemical reaction occurs when the battery discharges, converting aluminum and oxygen into alumina. Will Aluminum air cells replace lithium-ion battery? Alternative lithium-ion battery aluminum cells are still being tested and are not yet ready for commercial use. So in general, it's not clear whether aluminum air cells will replace lithium-ion battery, so let's see what problems aluminum air cells will have in replacing lithium-ion battery. In terms of battery life, the aluminum air battery is a real breakthrough compared to the lithium-ion battery. However, due to the anode corrosion and hydrogen during the discharge process, not only the anode data will be lost, but also the internal loss will be increased. In addition, aluminum air battery consumption is aluminum, when the end of the battery life to re-install aluminum and so on, greatly hindered the commercialization of aluminum air battery. In airborne applications, aluminum-air batteries are still an unknown quantity, even less so than hydrogen fuel cells. Why Aluminum Air Battery can't replace lithium-ion battery. 1. The aluminum-air battery is not a battery which can store electricity repeatedly, but a chemical reaction device which can release electricity. It works, he says, by oxidizing reactive metals in water to release energy, which is then exported as electricity through electrolytes and special electrode data. In general, for Aluminum Air Batteries, the active metal is aluminum, similar to Zinc–air battery, magnesium air batteries, only according to the activity of the metal (in water or air oxidation reaction intensity) , the use of electrolyte and other auxiliary information slightly different. 'just add water' essentially uses aluminum, not water, just to extend battery life. Chen Tao told reporters that during the operation of the battery, there is a stable output power flow, the metal aluminum is also in a stable oxidation and consumption flow, Aluminum hydroxide, electricity is made use of the chemical energy containing aluminum as a condition. A 100 kilogram aluminum air battery can store enough energy to carry 3,000 kilometers. After 3,000 km, the battery's life is over and it has to be reinstalled to make up for the aluminium. According to reports, aluminum air batteries as early as the 1960s have appeared. But up to now, its discussion still stays in the theory stage, the practical application is not many. At home, it is important to study the emergency power supply, but abroad, scientists either study some electrode data, or study the special purpose battery system, are trying to use aluminum-air battery technology to break. 2. Safety check the biggest bottleneck is the use of aluminum air batteries. In addition to the inconvenience of storing electrical energy, Chen Tao argues, there are also many disadvantages compared with other gas fuel cells, such as hydrogen fuel cells, which can be easily injected, stored, and transported in chemical reaction equipment, but for solid metal aluminum, obviously not convenient. Secondly, the second reaction is more, the reaction process is not easy to control, some reaction products to a certain extent to prevent the reaction to continue, the release of a large number of heat, as well as flammable and explosive gases. Aluminium seems to be playing a bigger role in the development of electric cars. One interesting phenomenon is that Tesla Electric cars in the United States can be increased to 300-400 km battery life, the important use of nickel-cobalt-aluminum terrain data, while our electric cars use nickel-cobalt-manganese. The difference between the two metals is aluminum. The aluminum data used by Tesla is important for rechargeable batteries. The effect of this is to increase the energy density of the battery, so that the same amount of battery can store more energy, so that the car mileage longer. Chen Tao believes that only from this perspective, is the real breakthrough. However, the security risk brought by this should be further studied in practice.
