“…Therefore, the solubility and the diffusion rate of O 2 would have significant impacts on the reaction [11,12]. It is confirmed that an appropriate choice of the electrolyte and increasing the O 2 partial pressure are effective strategies to improve the solubility and can achieve increased O 2 transport in the electrode [13]. Meanwhile, intelligent designs of the pore architecture and the electrode structure could also promote the transport [14,15].…”

“…Read et al, Yang et al and Tran et al showed that the specifi c capacity increased as the oxygen pressure increased. [38][39][40] This phenomenon indicates that practical application of Li-air batteries will not be easy. Most studies on Li-air batteries have been performed using pure oxygen gas, and, therefore, oxygen pressure is 1 atm.…”

In the past decade, there have been exciting developments in the fi eld of lithium ion batteries as energy storage devices, resulting in the application of lithium ion batteries in areas ranging from small portable electric devices to large power systems such as hybrid electric vehicles. However, the maximum energy density of current lithium ion batteries having topatactic chemistry is not suffi cient to meet the demands of new markets in such areas as electric vehicles. Therefore, new electrochemical systems with higher energy densities are being sought, and metal-air batteries with conversion chemistry are considered a promising candidate. More recently, promising electrochemical performance has driven much research interest in Li-air and Zn-air batteries. This review provides an overview of the fundamentals and recent progress in the area of Li-air and Zn-air batteries, with the aim of providing a better understanding of the new electrochemical systems.

“…The resistance associated with peroxide diffusion from the carbon to the catalyst can be minimised by taking advantage of a high surface area carbon (1200 m 2 g À1 ) in the active layer [128]. Some of the highest current densities (upwards of 3000 mA cm À2 ) were attainable when pure oxygen was used as the reactant instead of air, while elevated pressures will also have a similar effect [129,130].…”

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.
