General Theory of Disperse Metal Electrodeposits Formation

Electrochemical aspects of formation of dendrites

“…It is important to note that the current density to the tip of hemispherical protrusion does not depend on the size of it if k = 1. This makes a substantial difference between spherical microelectrodes in bulk solution [11] and microelectrodes inside diffusion layer of the macroelectrode [17]. In the first case the limiting diffusion current density depends strongly on the radius of the microelectrode.…”

“…The critical overpotential of dendritic growth initiation can be determined by plotting the logarithm of the slopes of the straight lines from [11]). …”

“…Spongy-like, cauliflower-like, needle-like, carrot-like, dendrites of various shapes, etc In these publications all aspects of morphology of electrodeposited metal are discussed, from dendritic growth initiation and dendritic growth [2,3,11] to the bright deposits formation [2,3,8] and the effect of hydrogen co-deposition on morphology of electrodeposits [3,9,14]. One of the most important conclusion derived by BES is the mechanism of disperse deposits formation, based on different behaviour of the macroelectrodes and microelectrodes under the same conditions of electrodeposition.…”

“…One of the most important conclusion derived by BES is the mechanism of disperse deposits formation, based on different behaviour of the macroelectrodes and microelectrodes under the same conditions of electrodeposition. The aim of this article is to discuss this phenomenon in the way given in [11] for the growth of dendrites. …”

The potentiostatic current transients and the role of local diffusion fields in formation of the 2D lead dendrites from the concentrated electrolyte

“…From the electrochemical point of view, a dendrite is defined as an electrode surface protrusion that grows under activation control, while electrodeposition to the macroelectrode is predominantly under diffusion control [1,[24][25][26][27]. Investigation of the mechanism of dendrite formation was initiated by Diggle et al [26].…”
