Will aluminum-air batteries replace lithium batteries?

Can aluminum-air batteries replace lithium batteries? It is undeniable that endurance is the biggest bottleneck in the commercialization of lithium batteries, and the super endurance of aluminum-air batteries is more conducive to the large-scale application of electric vehicles. But from this point alone, it is too early to say that aluminum-air batteries replace lithium batteries. For automotive applications, aluminum-air batteries are still an unknown. Geely Automobile Research Institute has done related simulation modeling experiments. From the results, the aluminum-air battery is more suitable as a battery for battery life. Aluminum-air battery is an energy source. Relative to batteries that can store electrical energy, an aluminum-air battery of the same weight can release more electrical energy. Its energy density is high, but its releasable power is extremely low. It cannot be used alone. Meet the needs of vehicles, especially when starting. This is equivalent to a fuel car. The fuel tank is large, but the engine is small. It can go a long way, but it goes very slowly. In contrast, the speed of lithium-ion batteries will be more stable. If the aluminum-air battery of the same power (that is, the vehicle has the same speed) is used, its weight will be about 4 to 5 times that of a lithium-ion battery. In other words, the standard energy of an electric vehicle should be that the strength of the aluminum-air battery is used in actual use to obtain a longer driving range. At the same time, it should be supplemented by the short of the aluminum-air battery and equipped with a power battery. Make the vehicle have good power performance. In fact, the aluminum-air battery car developed by Alcoa Canada still needs to retain lithium electronic batteries, and the aluminum battery will only start after the lithium battery is exhausted. It is worth mentioning that Tesla has also begun its layout in the field of aluminum-air batteries. According to foreign media reports, Tesla Motors filed a patent application for an extended-range hybrid lithium-ion battery pack system for electric vehicles on December 8, 2010, and was reviewed by the US Patent Office on June 25, 2013. by. This set of patents includes a standard lithium battery pack and a metal-air chemical battery pack. The lithium battery pack directly supplies power to the car, and the metal-air battery pack supplies power to the lithium battery pack. The industry believes that from the perspective of the technical characteristics of the aluminum-air battery itself, it seems more suitable as an emergency power source and a mobile battery. In the automotive field, lithium batteries represented by Tesla should remain the mainstream in a short time. The future development direction is to add fuel power batteries on the basis of existing batteries to form a hybrid vehicle power supply of'fuel power battery + battery' . However, in the choice of fuel power batteries, hydrogen fuel power batteries are superior to metal fuel power batteries such as aluminum-air batteries.
