Self-corrosion of aluminum alloy anodes has always been the focus of research on aluminum-air batteries. In this paper, the performance of Al-1.5Mg-0.05Sn-0.01Ga anode in different 4M KOH ethanol-water mixed solutions were investigated. The experiment results show that the mixed solutions are distinctly inhibited anode self-corrosion and the anode utilization rate is improved effectively. The results of molecular dynamics simulation show that the ethanol would reduce the transport of K+ and OH− ions, decrease the conductivity of the mixed electrolyte. When the electrolyte contains more than 50% ethanol, the discharge performance of the battery will be rapidly deteriorated.
