摘要：
This work investigated the discharge properties of the Mg-6Al-xCd alloy as a potential anode material for the Mg-air battery. The influence of the Mg-6Al-xCd alloy with cadmium content ranging between 0.5% and 1% on the electrochemical and discharge performances was investigated by means of microstructure characterization, electrochemical performance measurement and discharge test of the alloys. The results show that Mg-6Al-1.0Cd has the highest anode efficiency and specific capacity of 41.38% and 993.54 mAh/g, respectively. This good discharge performance is attributed to the addition of cadmium, which can inhibit self-corrosion and reduce the galvanic corrosion of the magnesium anode. The Mg-6Al-1.0Cd alloy can be used as a potentially ideal material for the Mg-air battery anode.
