“…There have been several fundamental efforts to understand the behavior of the zincate ion in an alkaline electrolyte [ 3 , 135-138 ] and also to understand the electrodeposition of the zincate ion. [139][140][141][142][143][144][145][146][147] Dirkse suggested that Zn(OH) 4 2 or polynuclear species may exist in supersaturated zincate solutions and that the existence of these species depends on the availability of OH − and free H 2 O molecules in the electrolyte. [ 137 ] Peng studied the mechanism of zinc electroplating and suggested that Zn(OH) 2 became Zn(OH) ad by gaining one electron and then Zn(OH) ad was reduced to Zn by gaining a second electron.…”

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.

“…Moderate and low values of overpotential significantly affect the morphology of zinc deposits, which may be described as boulder, layered, and mossy structures. [11][12][13] The morphology is also affected by the forced convection of the zincate electrolyte commonly used in zinc-air and zinc-nickel flow batteries. [14][15][16] These rechargeable zinc-based batteries can operate at quite high current densities 17,18 well above 50 mA/cm 2 .…”

This work emphasizes the importance of understanding the phenomena of dendrite formation occurring in rechargeable metal batteries. These batteries can reach quite a high specific energy but have inherently short life due to dendritic growth. The current work implements different tomographic methods to visualize dendritic growth in real time and to quantify various dendrite characteristics at submicron and nanoscale levels. The methodology presented here can be also extended to study the growth of other metal dendrites in aqueous and nonaqueous batteries.

“…This morphology consists of single crystallites perpendicularly oriented to the zinc surface with tree‐like or leaf‐like shapes. Their shape could vary, for example J. W. Diggle et al studied three different types of dendrites, classified by their growth rate; slow growth rate (SGR) at 3 μ m min −1 , moderate growth rate (MGR) at 24 μ m min −1 and fast growth rate (FGR) at 67 μ m min −1 (Figure ).…”

Summary New applications and emerging markets in electromobility and large‐scale stationary energy storage require the development of new electrochemical systems with higher energy density than current batteries. Rechargeable metal–air batteries, mainly lithium–air and zinc–air systems, are considered one of the most promising candidates. In contrast to lithium, zinc is abundant, inexpensive and its electrodeposition in aqueous electrolytes is relatively easy. Unfortunately, achieving a rechargeable zinc–air battery is still hindered by various technical problems related to the reversibility and lifetime of the electrodes. The most widely used electrolyte in zinc–air batteries has been the classical aqueous alkaline. In this context and with the main objective of providing a complete overview, we studied a wide number of articles starting from the beginning of the development of secondary zinc–air batteries (1970–1980s) to more recent works, with the aim of compiling all available information. It is essential to revise older papers to find relevant information that may get otherwise forgotten and not taken into account to develop new solutions. This information could also be applied in other storage systems based on zinc as nickel–zinc, zinc hybrid or zinc‐ion. Copyright © 2016 John Wiley & Sons, Ltd.
