“…Several researchers have explored the use of chloroaluminate ionic liquids as electrolytes for aluminium batteries [167,178]. One drawback is difficulty with preparation due to the highly exothermic reaction between 1-ethyl-3-methylimidazolium chloride (EMIC), and AlCl 3 , making them expensive [167,179,180]. Other chloroaluminate ionic liquids such as trimethylphenyl ammonium chloride (TMPAC)-AlCl 3 are easy and inexpensive to prepare in a relatively high state of purity since TMPAC is commercially available in high-purity [181].…”

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.

“…Several recent reviews have covered the use of ionic liquids in electrochemistry [5][6][7][8][9][10] and the most comprehensive of these is the book by Ohno,11 which not only covers the fundamental aspects but also a wide range of applications including lithium batteries, photoelectrochemical cells, fuel cells and capacitors. Reviews by Compton 12 and Endres are also recommended for their coverage of fundamental electrochemistry and electrodeposition.…”

Ionic liquids are molten salts that have low melting points. This review concentrates upon eutectic mixtures of quaternary ammonium salts and metal salts (usually halides). These so-called eutectic based ionic liquids can be used for the electrodeposition and dissolution of a wide range of metals and alloys. The review highlights the technological challenges involved in the application of ionic liquids to metal finishing.

“…It is very difficult to perform electro deposition of aluminum in an aqueous solution because aluminum is not a very noble metal. In spite of being able to deposit Al from a room-temperature ionic liquid [99], there have been no established techniques well in virtue. A method used for the electroless plating of Al based on using AlCl 3 -1-ethyl-3-methylimidazolium chloride (AlCl 3 -EMIC) ionic liquid as the electrolyte and lithium hydride (LiH) as the solid reducing agent.…”

Electroless metallic coating is referred as the deposition of a substrate material by the process of chemical or autocatalytic reduction of aqueous metal ions deposited to a substrate material without any external supply of power. Electroless nickel alloys are generally considered synonymous to the word "electroless coating" as ~90% of productions in industries are of this alloy coating. Rest of the electroless metallic coatings includes gold, copper, palladium, cobalt, silver, etc. These electroless metallic coatings (other than electroless nickel coatings) are also one of the vibrant areas in the field of materials properties and surface engineering research. From the year 2000 to till date, nearly 1000 SCI indexed research papers were published on this topic. However, no comprehensive studies about the recent progress on this topic were reported elsewhere so far. In this context, the present chapter aims to give a complete overview on various aspects of the rest of the electroless metallic nanocoatings/layer as a whole. More importance will be on the recent developments of the nanocharacteristics and future scopes.
