Abstract
In this research, metal-air battery based on Al, Al-0.1In-0.1Ga, Al-0.1In-0.1Ga-0.1Sn, Al-0.1In-0.1Ga-3.0Pb, Al-0.1In-0.1Ga-0.1Sn-3.0Pb (wt%) is prepared and the battery performance is investigated by constant current discharge test in 4mol/L KOH solutions. The characteristics of the anodes after discharge are investigated by scanning electron microscopy (SEM) and self-corrosion rate measurement. The results show that Al-0.1In-0.1Ga-0.1Sn-3.0Pb has higher electrochemical performance and lower self-corrosion rate. Using Al-0.1In-0.1Ga-0.1Sn-3.0Pb as anode could improve the performance of Al-air battery, and solve the problem of severe self-corrosion and passivation.
