Abstract

In this study, an Al-Zn-B alloy was developed to investigate AlB2 intermetallic phase effect on electrochemical performance in Al-air battery anodes. Self-corrosion, galvanostatic dissolution tests, electrochemical measurements, and surface characterization methods were conducted to observe the effect of 1-5 wt% B doping to the Al-5 wt% Zn (Al5Zn). In 3 wt% B doped alloy (Al5Zn3B), 20% higher corrosion rate was achieved than Al5Zn alloy. The corrosion potential of the alloy samples was changed from - 1.841 V vs Ag/AgCl to - 1.870 V vs Ag/AgCl values, by adding 3 wt% B elements to Al5Zn alloy. [GRAPHICS]
