Metal-air batteries have drawn considerable attention from
companies and researchers since they are a promising source of
energy for future generations of electric vehicles (EVs). Lithium-air,
zinc-air, magnesium-air, aluminium-air, etc. are the most evaluated
electrochemical pairs because they use oxygen from the air as one
of the main battery reactants, reducing the weight and the cost of
the battery and permitting higher space for energy storage. Metalair flow batteries are also promising because of the reduction of the
cost and their application in large scale energy storage
