Despite their promising characteristics, pure Al materials are unstable as anodes in Al–air batteries and a common method to improve electrochemical property involves the use of Al alloys. Based on this, numerous studies have been conducted to create better performance Al anodes by mixing Al with other metals such as Mn, Mg, Bi, In, Sn, Zn
Mg metal as an anode material is facing two main challenges: high self-corrosion rate and formation of a passivation layer Mg(OH) 2 which reduces the active surface area. In last decades, a number of Mg alloys, including Mg-Ca, Mg-Zn, commercial Mg-Al-Zn, Mg-Al-Mn, and Mg-Al-Pb alloys, have been studied as anode materials for Mg-air batteries.
