Aluminum-air battery is also a kind of fuel battery. The “charging mode” of aluminum-air battery is replacing aluminum materials. It is similar to the Zinc-air battery used in hearing aids.
Aluminum-air battery, a kind of metal fuel battery with high energy density and low power density, can be widely applied in facilities with low power. The only way to apply it on electric vehicle is to use it cooperatively with lithium battery.
In view of its active chemical property, it is difficult to ensure its security and stability. Therefore, it is still in experimental stage.
In addition, aluminum-air battery is also confronted with the problem of industrial chain. Both zinc-air battery and aluminum-air battery follow the following circulation:
1. Metal manufacturer prepare metal through electrolyzing metallic oxide;
2. Transferring metal to electrical changing station;
3. Replacing metallic oxide in electric vehicle with metal (metal becomes metallic oxide after discharging);
4. Metal manufacturer recycle metallic oxide for reutilization.
In this process, a complete industrial chain is needed, from manufacturing, transportation, replacement, to recycling. Is it possible to build electrical changing stations all around the country?
As a result, even aluminum-air battery enters mass production period, it can only be applied to vehicles with fixed electrical changing stations, such as city buses and taxis. Just like hydrogen fuel battery, it’s really difficult to achieve overall popularization.
