1, Description 

When was the aluminum air battery invented?

Al–air batteries were first proposed by Zaromb et al. [15, 16] in 1962. Following this, efforts have been undertaken to apply them to a variety of energy storage systems, including EV power sources, unmanned aerial (and underwater) vehicle applications and military communications [17,18,19,20].

3. Advantages:
Compared with traditional battery, the main advantages of aluminum-air batteries are:
1. Aluminum has high specific energy and high conversion efficiency.
2. Strong environmental adaptability, the ambient temperature is -30～+55℃, it can
generate electricity as long as there is water, and the power output is full.
3. Safe and reliable, the aluminum electrode air electrode material has stable chemical properties, does not burn or explode, the
battery core has a low operating temperature, no mechanical vibration, no fire and explosion and other safety hazards.
4. Green and pollution-free, economical and cost-effective. The raw material resources are abundant, the production of aluminum hydroxide and other aluminum by-products can be recycled and reused, and the manufacturing, operation, and maintenance costs are economic.
