Abstract: In order to improve the electrochemical performance of aluminum alloys as anodes in metal-air batteries, the effects of different contents of Sn elements on the electrochemical properties of Al-Mg-Ga alloys were studied in this paper. The open circuit potential, polarization curve, electrochemical impedance spectroscopy and constant current discharge of alloys with different contents of Sn in 6 mol/L KOH electrolyte were tested. The results show that Sn element can significantly improve the performance of the aluminum alloy anode. Compared with pure aluminum, the electrochemical performance of the alloy has been greatly improved; when the Sn content is 0.1wt%, the hydrogen evolution corrosion of the alloy is the slowest. The electrochemical performance is the best, and the alloy has the best comprehensive performance.
