摘要：
Aluminum (Al) is a candidate anode material for metal-air batteries. But low anode efficiency and power density hinder its commercial application. This paper reports a kind of Al alloy as the anode for Al-air batteries. The electrochemical properties of the anodes are investigated using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) in 4 M KOH. Battery performance is tested by constant current discharge at different current densities. The results show that the alloy as the anode has higher electrochemical activity and lower polarization. The new alloy anode provides higher energy density and power density for Al-air batteries. (C) 2015 The Electrochemical Society. All rights reserved.
