“…Most of the previous ECD experiments refer to purely binary electrolytes [4][5][6][7][8][9][10][11][12][13]. In contrast, experiments with electrolyte solutions containing added nondepositing cations, such as those reported here, are scarce in the literature [14][15][16].…”

“…Here we report on our striking experimental discovery of fingering development in a completely unexpected scenario, that of thin-layer electrochemical deposition (ECD). Different from the most characteristic ECD morphologies, from the disordered fractals to the regularly patterned branching aggregates [4][5][6][7][8][9][10][11][12][13][14][15][16], the deposits obtained in these experiments show a small scale filament structure, which fills space densely, and is enclosed by a fingerlike, long-wavelength modulated envelope (Fig. 1).…”

Fingerlike Aggregates in Thin-Layer Electrodeposition

et al. 1996

Electrodeposition experiments conducted in a thin-layer horizontal cell containing a nonbinary aqueous electrolyte prepared with cupric sulfate and sodium sulfate gave rise to fingerlike deposits, a novel and unexpected growth mode in this context. Both the leading instability from which fingers emerge and some distinctive features of their steady evolution are interpreted in terms of a simple model based on the existing theory of fingering in fluids.

“…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.

“…There have been several experiments in which ramified growth is confined to a single plane and is effectually two dimensional [17,[37][38][39]. However, for most systems ramified growth occurs in all three dimensions.…”

“…For well over a century it has been known, however, that the layer deposited during electrodeposition is prone to morphological instabilities, leading to ramified growth of the electrode surface. Over the years, many experimental, theoretical, and numerical studies have been devoted to increasing the understanding of this ramified growth regime [12][13][14][15][16][17][18][19][20]. Big contributions to our understanding of the growth process have come from diffusion-limited aggregation (DLA) models [21,22] and, more recently, phasefield models similar to those that have successfully been applied to solidification problems [23][24][25][26][27][28][29].…”

Sharp-interface model of electrodeposition and ramified growth

We present a sharp-interface model of two-dimensional ramified growth during quasisteady electrodeposition. Our model differs from previous modeling methods in that it includes the important effects of extended spacecharge regions and nonlinear electrode reactions. The electrokinetics is described by a continuum model, but the discrete nature of the ions is taken into account by adding a random noise term to the electrode current. The model is validated by comparing its behavior in the initial stage with the predictions of a linear stability analysis. The main limitations of the model are the restriction to two dimensions and the assumption of quasisteady transport.
