2.1. Structure and principle of magnesium–air batteries The magnesium–air battery is a new and emerging type of clean and efficient semi–fuel cell (voltage, 3.1 V; energy density, 6.8 kW h kg –1; theoretical volumetric capacity, 3833 mA h cm –3) , .
Magnesium–air batteries combine the advantages of magnesium and metal–air batteries, with higher energy density, stable discharge, no charging, direct mechanical replacement, and no environmental pollution, highlighting their potential as. Promising energy storage systems.
Developing novel cathode structures and efficient bifunctional catalysts is crucial for increasing the discharge voltage and enhancing battery power also a key factor in determining whether magnesium–air batteries can replace lithium batteries as mainstream next–generation energy storage devices.
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.
Magnesium-air battery consists of magnesium as anode, electrolyte, and oxygen from air as cathode. 94, 95 The cathode represents a layer of active carbon containing catalyst and hydrophobic additives (TEFLON suspension in a quantity of 10–25%) contacting with free electrolyte.
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.
