“…6 These key obstacles limit the practical utilization of Mg–air batteries. To address these challenges, researchers have made considerable efforts, including multicomponent alloying, 1 the construction of novel anode structures, 7,8 the incorporation of antifreeze hydrogel electrolytes, 9 organic electrolytes, and ionic liquid electrolytes, 10 the adoption of high-concentration “water-in-salt” electrolytes, 11–13 modifications to the anode interface, 14,15 and the addition of electrolyte additives. 16,17…”
