The aim of this review article on recent developments of mechanochemistry (nowadays established as a part of chemistry) is to provide a comprehensive overview of advances achieved in the field of atomistic processes, phase transformations, simple and multicomponent nanosystems and peculiarities of mechanochemical reactions. Industrial aspects with successful penetration into fields like materials engineering, heterogeneous catalysis and extractive metallurgy are also reviewed. The hallmarks of mechanochemistry include influencing reactivity of solids by the presence of solid-state defects, interphases and relaxation phenomena, enabling processes to take place under non-equilibrium conditions, creating a well-crystallized core of nanoparticles with disordered near-surface shell regions and performing simple dry time-convenient one-step syntheses. Underlying these hallmarks are technological consequences like preparing new nanomaterials with the desired properties or producing these materials in a reproducible way with high yield and under simple and easy operating conditions. The last but not least hallmark is enabling work under environmentally friendly and essentially waste-free conditions (822 references).

“…The lightness of aluminium energy storage technologies, such as Al-H 2 O 2 or Al-S systems, has meant that they have received renewed interest for a variety of applications [2,3]. Among these systems is the aluminiumeair battery with a practical specific energy density of 400 W h kg À1 surpassing that of lithium-ion batteries [4e7].…”

“…The extent to which this large body of work has been reviewed is variable. For example some surveys covering the variety of aluminium energy storage systems devote a subsection to the aluminiumeair battery electrochemistry [2,3]. Others focus solely on aluminiumeair batteries and detail the advances made together with their developing applications [13e20], such as a power source for electric vehicles [21,22].…”

“…The rationale behind the choice of alloying elements, their concentration and the mechanisms by which they activate the aluminium to yield higher anodic currents is discussed. Given that the maximum electrical energy cycle efficiency of an aluminium energy storage system is 22% [2], one lower cost solution involves using commercial grade aluminium and adding inhibitors to the electrolyte. The effectiveness of these inhibitors, singly and in combination, and in different concentrations is reviewed.…”

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.

Abstract. As a kind of clean energy, the research of aluminum air battery is carried out because aluminum-air battery has advantages of high specific energy, silence and low infrared. Based on the research on operating principle of aluminumair battery, a novel aluminum-air battery system was designed composed of aluminum-air cell and the circulation system of electrolyte. A system model is established to analyze the polarization curve, the constant current discharge performance and effect of electrolyte concentration on the performance of monomer. The experimental results show that the new energy aluminum-air battery has good discharge performance, which lays a foundation for its application.
