“…Alloying magnesium with element aids in the peeling of corrosion products and promotes corrosion resistance in general, hence improving the battery performance 49 . The elements commonly used for Mg alloy are aluminum (Al), lead (Pb), zinc (Zn), manganese (Mn), lithium (Li), tin (Sn), indium (In), gallium (Ga), mercury (Hg), and several rare earth elements (REEs) 25,50‐54 . Commercial Mg‐Al‐Zn alloys are commonly referred as the AZ series, which comprises aluminum in the range between 1 and 10 wt.%, and zinc, with an amount less than that of aluminum, is one of the most frequently investigated and used in industry 55‐57 .…”

Summary This study aimed to provide a critical review of the magnesium‐air fuel cell (MAFC) system to provide readers with an overall comprehension of MAFC, which focuses on the modification of the magnesium anode and properties of saltwater as an electrolyte. Although MAFC is benign to the environment, it is well‐known for its challenging corrosion issue and by‐product deposition that affect its durability for commercialization and long‐term application. Since that MAFC is able to use seawater as electrolyte, it has great potential to be used as an alternative energy option for the marine sector. This journal will dissect the ability of MAFC to be used as a competitive alternative energy. Over the years, researchers have adopted several approaches, such as experimenting with different types of magnesium alloy and anode fabrication techniques, to tackle corrosion problems to alter the microstructure and mechanical properties of the anode in addition to applying a coating protection and using Mg‐based composite material. Furthermore, studies intriguingly and gradually focused on electrolyte formulation with different types of additives to address the debilitating precipitation issue and improve the discharge performance. Given the problems that arise in the system, currently, MAFC commercial products are only suitable as emergency back‐up power. In future work, an improved storage system for MAFC should be built to accommodate the precipitation products while maintaining the desired cell performance.

“…It is clear that external field treatment can refine the α-Mg grains. It has been reported that the fine-grained microstucture can improve the discharge properties of Mg-air battery [31,32]. Refined grian size means the higher density of grain boundaries, which can dramatically promote the dischrge activity [33].…”

“…Magnesium (Mg) alloys are traditional light-weight engineering materials, which are used in aviation, vehicle construction, and communication equipment . They are also excellent energy materials due to their high electrochemical activity, high theoretical specific energy, abundance, and moderate cost [23][24]. For example, the Mg-air battery has aroused a lot of interest in recent years [24][25][26][27][28][29][30][31].…”

“…In response, novel Mg alloy anodes have been explored [33][34][35], such as the Mg-Al-Pb [24,26,[36][37], Mg-Al-Zn [28][29][30][38][39], Mg-Ca [33][34], and Mg-Li [40][41][42]. These Mg anodes still have problems [28,32,34], such as security (Mg-Li) [28,34], toxicity (Mg-Al-Pb) [28,34], and only presenting a low unsteady discharge voltage [23,32] (Mg-Al-Zn and Mg-Ca). That is to say, it is of great significance to develop novel safety Mg anodes with excellent discharge properties.…”

Mg-Sn-Y alloys with different Sn contents (wt%) were assessed as anode candidates for Mg-air batteries. The relationship between microstructure (including the second phase, grain size, and texture) and discharge properties of the Mg-Sn-Y alloys was examined using microstructure observation, electrochemical measurements, and galvanostatic discharge tests. The Mg-0.7Sn-1.4Y alloy had a high steady discharge voltage of 1.5225 V and a high anodic efficiency of 46.6% at 2.5 mA•cm −2 . These good properties were related to its microstructure: small grain size of 3.8 µm, uniform distribution of small second phase particles of 0.6 µm, and a high content (vol%) of ( )/( ) orientated grains. The scanning Kelvin probe force microscopy (SKPFM) indicated that the Sn 3 Y 5 and MgSnY phases were effective cathodes causing micro-galvanic corrosion which promoted the dissolution of Mg matrix during the discharge process.
