The Discharge Performance of Mg-3In-xCa Alloy Anodes for Mg–Air Batteries

Considering the advantage of safety and cost, designing a Mg–air battery with high capacity has been highly sought in recent years. However, self-corrosion passivation Mg anode critically reduce discharge performance, hindering large-scale application batteries. In this study, series as-cast extruded Mg-3In-xCa alloys were successfully fabricated. Microstructures, chemical composition, performance investigated to optimize content Ca (x). The selected Mg-3In-3Ca alloy as represented best including 0.738 V voltage, 1323.92 mAh g?1 specific capacity, 61.74% anodic efficiency at current density 30 mA cm?2. All its parameters vastly superior pure battery. addition, synergistic effects on promoting electrode properties evaluated detail, using SEM electrochemical analysis, which is expected trigger follow-up research high-performance
