Novel cathodic materials for Aluminum-air battery

Metal-air batteries have gained great interest due to their high energy density and capacity, low cost (depending on the metal anode), the negligible dependence of their capacity on operating load and temperature, and constant discharge voltage. Up to now, several different types of metal-air batteries, such as lithium (Li)-air, sodium (Na)-air, potassium (K)-air, zinc (Zn)-air, magnesium (Mg)-air, and aluminum (Al)-air batteries have been extensively studied. Metal-air batteries exhibit high…
