The pursuit of sustainable and high-performance energy storage technologies has placed renewed focus on achieving higher energy densities in next-generation systems. Among various candidates, metal–air batteries stand out for their exceptional energy density, durability, and specific power, offering clear advantages in cost, weight, and environmental impact. Within this class, magnesium–air batteries are desirable due to magnesium’s high theoretical voltage, energy density, and its abundance and affordability. Despite these advantages, the practical deployment of magnesium alloys as anodes remains hindered by rapid self-corrosion in aqueous electrolytes, sluggish electrochemical kinetics, and parasitic reactions, especially hydrogen evolution. Addressing these challenges requires electrolyte formulations that strike a balance between anode efficiency and discharge performance. These limitations hinder the practical application of Magnesium-Air batteries. Addressing these challenges requires solutions on various approaches, with the primary methods focusing on modifying the anode material and/or electrolyte This study presents a novel approach that utilizes synergistic mixtures of electrolyte additives, rather than individual components. Discharge experiments demonstrate that the proposed additive combinations effectively mitigate the chunk effect and stabilize the oxygen reduction reaction at the Mg anode. The findings provide a framework for designing cost-effective, high-performance electrolytes, advancing the development of efficient Mg–air battery systems.
