Description
Summary:In this study, an Al–Zn–B alloy was developed to investigate AlB 2 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. Graphical abstract
