The reactions involved in the batteries are Mg electrochemical oxidation to Mg ions in the anode and the oxygen reduction reaction in the cathode. Mg plates are common materials for the Mg anode and the drawback is the high level of corrosion. Mg alloys and Mg nanoparticles can improve the performance of the Mg anode.
During the operation of magnesium–air batteries, the anode metal magnesium undergoes an electrochemical oxidation reaction, loses electrons, and reaches the three–phase junction of the air electrode through an external circuit, reacting with oxygen and water to generate hydroxide ions.
Considering the microstructure and electrochemical performance of the anode significantly influence the overall efficiency of magnesium–air batteries, more traditional and innovative advanced metallurgical processes are expected to emerge in the future. (4) Development of new catalyst synthesis processes and design of the cathode structure.
Thus, magnesium-based batteries are regarded to be bestowed with potentials to revolutionize the energy storage industry and contribute to the development of a sustainable and environmentally friendly energy system.
The battery only requires replacement of the magnesium anode plate and replenishment with a fresh electrolyte when the anode is completely discharged or when the electrolyte is heavily contaminated and fails to meet discharge standards. Hence, this study focuses on mechanically rechargeable magnesium–air batteries. Fig. 5.
Despite notable achievements in various aspects of magnesium–air batteries, several challenges remain. Therefore, the following key research directions are proposed. (1) Investigation of the mechanism and four-electron transfer criteria for ORR and OER in magnesium–air batteries.
