This work investigates the performance of magnesium (Mg) - air battery with modified AZ31 anode, designated as AZ31M. It successfully achieves a high anodic efficiency of 73% with the energy density of 1692 mWh g and capacity of 1582 mAh g at 1 mA cm in 3.5% NaCl. These battery parameters are higher than those reported for most Mg anodes. The addition of the cost-effective La, Ce and Ca refines the bulk MgAl in AZ31 into small MgAl, AlCa and Al(Ca, RE), leading to a uniform discharge with slight galvanic corrosion and low anode delamination effect. The AZ31M anode is a potential candidate Mg anode for wide application of Mg-air battery.
