Metal-air batteries are an innovative battery technology that combines the characteristics of traditional lithium-ion batteries and fuel cells. These batteries use oxygen from the air as the reactant and highly active metals (such as lithium, sodium, magnesium, etc.) as the anode. Compared to traditional batteries, metal-air batteries offer several advantages: 1. High energy density: they can deliver up to 10 times the power output of commercially available nickel-cadmium batteries; 2. Environmentally friendly: they pose no environmental pollution risks; 3. Cost-effective: metal-air batteries' raw materials are cheaper than lithium-ion batteries. This is particularly important as the supply of lithium is limited, and its price continues to rise. The rechargeable nature of metal-air batteries makes them a promising energy storage solution.
