Abstract
The discharge and corrosion behaviour of Mg-Li-Al-Ce-Y-Zn alloy in 3.5 wt.% NaCl solution is investigated by electrochemical techniques, and compared with that of pure magnesium, AZ31, and Mg-Li-Al-Ce-Y alloys. The results indicate that Mg-Li-Al-Ce-Y-Zn exhibits desirable performance in half-cell tests and battery discharge. The peak power density of the Mg-air battery with Mg-Li-Al-Ce-Y-Zn anode is comparable with that of Mg-H2O2 semi-fuel battery. Its anodic efficiency at 10 mA cmâ2 reaches (60.6 ± 0.2)%, which is significantly higher than that of the state-of-the-art AP65 magnesium alloy. Moreover, the dissolution mechanism of Mg-Li-Al-Ce-Y-Zn is also characterized based on electrochemical response and microstructure observation.
