“…One novel approach employed a polymer mixture of polyacrylic acid, PAA encapsulating particles of aluminium powder (11.5e45 mm) and facilitating hydroxyl ion conduction [158]. This technique meant that the reaction product, Al(OH) 3 , remained mostly entrapped by the PAA, helping to maintain electrolyte conductivity throughout the discharge.…”

h i g h l i g h t s< Discussion of the rationale to choose a suitable alloy for Aleair battery. < Effect of the properties and preparation route to enhance the oxidation of Al. < Effect of the inhibitors on the anode oxidation in the alkaline electrolyte. This review shows the influence of the materials, including: aluminium alloy, oxygen reduction catalyst and electrolyte type, in the battery performance. Two issues are considered: (a) the parasitic corrosion of aluminium at open-circuit potential and under discharge, due to the reduction of water on the anode and (b) the formation of a passive hydroxide layer on aluminium, which inhibits dissolution and shifts its potential to positive values. To overcome these two issues, super-pure (99.999 wt%) aluminium alloyed with traces of Mg, Sn, In and Ga are used to inhibit corrosion or to break down the passive hydroxide layer. Since high-purity aluminium alloys are expensive, an alternative approach is to add inhibitors or additives directly into the electrolyte. The effectiveness of binary and ternary alloys and the addition of different electrolyte additives are evaluated. Novel methods to overcome the self-corrosion problem include using anionic membranes and gel electrolytes or alternative solvents, such as alcohols or ionic liquids, to replace aqueous solutions. The air cathode is also considered and future opportunities and directions for the development of aluminiumeair cells are highlighted.

“…Owing to the sluggish reaction kinetics, oxygen reduction reaction (ORR) is considered as the major bottleneck for developing advanced metal air batteries [1][2][3][4][5][6] . To address such issue, Pt-based catalysts are widely used as the state-of-the-art catalyst.…”

“…Parasitic hydrogen evolution caused by anode corrosion during the discharge process has long been recognized as an obstacle to further commercialization of the aluminum−air battery because it not only causes additional consumption of the anode material but also increases the ohmic loss in the cell. Efforts to suppress the parasitic corrosion include doping high-purity grade aluminum (99.999% grade) with particular alloying elements and introducing corrosion inhibitors into electrolyte . Nevertheless, doing these will definitely increase the cell production costs.…”

The aluminum-air battery has potential to serve as a near-term power source for electric vehicles. Parasitic hydrogen evolution caused by anode corrosion during the discharge process, however, has long been recognized as an obstacle to further commercialization of the aluminum-air battery. This paper focuses on the parasitic reaction impacts with an aim of better understanding and managing the parasitic reaction. On the basis of a mathematical model, effects of the parasitic hydrogen evolution on cell flow field, ionic mass transfer and current density are investigated. Besides, the possibility of utilizing the parasitically evolved hydrogen to increase the total power output is evaluated.
