Abstract:A novel precipitate-free Mg-0.1Sn anode with a homogeneous equal-axis grain structure was developed and rolled successfully at 573 K. Electrochemical test results indicate that the Mg-0.1Sn alloy exhibits enhanced anode dissolution kinetics. A Mg-air battery prepared using this anode exhibits a cell voltage of 1.626 V at 0.5 mA/cm2, reasonable anodic efficiency of 58.17%, and good specific energy of 1730.96 mW·h/g at 10 mA/cm2. This performance is attributed to the effective reactive anode surface, the suppressed chunk effect, and weak self-corrosion owing to the homogeneous basal texture.
Key words: Mg-air battery; Mg-Sn anode; grain structure; electrochemical behavior; discharge performance
