“…In recent decades, the Mg–air battery has attracted intensive attention, especially for emergency rescue, because of its high theoretical energy density, which could reach three times that of the Li-ion battery. , In addition, the Mg–air battery is a scalable and environment-friendly technology due to the low cost of raw materials and nontoxic reaction products. ,, Therefore, the Mg–air battery has been considered as one of the important developing directions of the next-generation batteries . However, the application of the Mg–air battery has been seriously limited by its high self-corrosion rate and barrier effect caused by the accumulation of discharge products on the surface of Mg anode. , …”

Magnesium−air battery has been considered promising for electrochemical energy storage or as a conversion device due to its high theoretical energy density and low cost. However, the experimental energy density is far lower than the theoretical value due to the intense hydrogen evolution of the Mg anode upon discharging. Herein, we have successfully developed a novel Mg 64 Zn 36 (at. %) alloy via single-phase design. The as-prepared Mg 64 Zn 36 anode possesses a high discharge specific capacity of 1302 ± 70 mAh g −1 and extraordinarily high efficiency of 94.8 ± 4.9%, which breaks the records of efficiency among all of the reported Mg anodes. The superior high efficiency is attributed to the anodic hydrogen evolution being inhibited by Zn alloying, which passivates the Mg matrix. The intermediate ion Mg + produced during discharging is dramatically limited by the integrated passive film and is totally converted into Mg 2+ electrochemically through the film. Meanwhile, the uniform discharging products due to the homogeneous microstructure of Mg 64 Zn 36 co-contribute to the high efficiency. The design of the Mg−Zn alloy may open a new avenue for the development of Mg−air batteries.

“…Secondly, magnesium has a relatively high capacity of 2.205 A•h/g. As a consequence, a magnesium anode can theoretically provide higher battery capacity [18,19]. Thirdly, magnesium has a low density of 1.74 g/cm 3 , which can reduce the quality of the battery system.…”

Bi, a group 15 element, was added to magnesium alloys and applied to seawater batteries in marine operating machinery to improve the electrochemical performance and corrosion resistance of the battery. The electrochemical properties of as-cast pure Mg, Mg–8Al, and Mg–8Al–xBi alloy anodes in 3.5% NaCl solution were researched. Electrochemical impedance spectroscopy and an immersion test in 3.5% NaCl solution show that the Mg–8%Al–0.4%Bi alloy provides better corrosion resistance than Mg and the Mg–8Al alloy. The galvanostatic discharge results show that the Mg–8%Al–0.4%Bi alloy revealed better electrochemical properties and utilization efficiency in 3.5% NaCl solution. The Mg17Al12 and BiOCl phases formed during the discharge process of the Mg–8%Al–0.4%Bi alloy play an important role in improving the electrochemical performance and utilization efficiency of the alloy.

It is well known the voltage output of magnesium air battery is low against volume of the battery. There is a lot of research being done on magnesium alloying to overcome the corrosion of metal and on the improvement of power of the battery, but there is no study on the optimization of the voltage output of the battery. In this study, various experiments are conducted to optimize the voltage output. Experiments were designed to see a change in voltage output with varying gap distance and to understand a relation between voltage output and concentration of electrolyte.
