Can air generate electricity? "Aluminum water air" battery black technology

Metal-air battery, also known as metal-air fuel cell or metal fuel cell, is a kind of power generation/energy storage device which directly converts the Chemical Energy of Light metals such as magnesium and aluminum into electricity. It has the advantages of high energy density, low cost, high safety, low heat radiation, low noise, long storage time, long discharge life, wide temperature range, rich resources and no pollution In particular, the specific energy density of aluminum air fuel cells is much higher than that of other conventional batteries. The theoretical energy density of aluminum can reach 8,140 watt hours per kilogram, which is tens of times higher than the current commercial lithium-ion battery. Aluminum is the most abundant metallic element in the Earth's crust, low cost, safety and environmental protection, stable performance, known as the "21st century-oriented Green Energy. ".
