“…8(b) and (d), it can be observed that two alloys present entirely different microscopic morphologies. Alloy 1 exhibits lamellar corrosion and cracks due to the activation effect of Ga and Sn elements, which is similar to the previous report (Ref 12). The surface of Alloy 2 is full of small pits, and it can be in contact with some In-rich inclusions.…”

Al-0.5 wt.%Mg-0.08 wt.%Sn-0.05 wt.%Ga-0.05 wt.%In and Al-0.5 wt.%Mg-0.08 wt.%Sn-0.05 wt.%Ga alloys were prepared by melting, casting and cold rolling. Corrosion and discharge behaviors of the two experimental alloys were investigated by electrochemical measurement, self-corrosion rate measurement, air battery testing, and scanning electron microscopy. The results showed that Al-Mg-Sn-Ga-In alloy exhibited higher electrochemical activity than Al-Mg-Sn-Ga alloy in 2 M NaCl solution, while it showed lower electrochemical activity than Al-Mg-Sn-Ga alloy in 4 M NaOH solution. By comparison with the air battery based on Al-Mg-Sn-Ga alloy, the battery with Al-Mg-Sn-Ga-In alloy cannot exhibit better discharge performance in 4 M NaOH electrolyte. However, the performance of the air battery based on Al-Mg-Sn-Ga-In alloy was greatly improved due to the In-rich inclusions and the uniform corroded morphology in 2 M NaCl electrolyte. Thus, Al-Mg-Sn-Ga-In alloy was a good anode material for Al-air battery in 2 M NaCl electrolyte.

“…Research results also show that Al-air batteries can use either alkaline or brine electrolytes, such as NaCl or NaOH solution ( Ref 8,14,15). The alkaline electrolyte improves Alair batteries especially ( Ref 9,12,16), however, the Al matrix is consumed invalidly by a parasitic hydrogen evolution reaction (Ref 17), as follows:…”

“…The second small inductive loop at LFs could be attributed to the coordination bond, which formed between aluminium ions and additive. The constant phase element which admittance is described as: Q ¼ Y 0 ðjwÞ n (12) where j is the imaginary root, w is the angular frequency, Y 0 is the magnitude, and n is the exponential term [34].…”

“…A lot of efforts have been devoted to the study of Zn-air [3] and Al-air batteries [17], but works relative to Mg-air batteries are scarcer. In search of the improvement of electrochemical performances of metal-air batteries, several Mg-based materials have been tested as anodes; most of them are multiphase or composite materials [18][19][20][21]. On the other hand, morphology effects (nano, meso…) of the anode materials have been reported [22,23].…”

The intermetallic compound Mg 2 Al 3 has been selected for this work to be tested as anode in a metal-air battery. The compound is prepared by a high-temperature synthesis from elements and its cubic structure (Fd 3 m, a=28.2341(3) Å) has been refined from X-ray single crystal diffraction data. It is characterized by a high level of disorder with a large number of partially filled atomic sites, split positions, and atomic mixing. The compound displays an interesting behavior towards self-corrosion in alkaline and saline environments, but the better electrochemical performances are obtained in saline NaCl electrolyte. It is shown that both Al and Mg are involved in the oxidation reaction that occurs at the Mg 2 Al 3 electrode used as anode in a metal-air battery. The operating voltage of an Mg 2 Al 3 -air cell is remarkably stable over several hours, and the Mg 2 Al 3 anode efficiency is higher than that of a pure Mg anode in a saline environment.
