Electrochemical aspects of formation of dendrites

Abstract: The one of the main contributions of Belgrade Electrochemical School to the field of metal electrodeposition is investigation of a mechanism of formation and growth of the disperse deposits. 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 … Show more

“…4b), the Te and Bi deposits are porous in nature and tend to form dendritic-type structures, as previously is observed for both elements in electrodeposition studies [70,71]. Moreover, it is known that the application of an overpotential can lead to dendrite growth [72] and in this case, the dendritic growth is most likely due to the overpotential applied during the electrodeposition of the sacrificial elements (mostly Cu) as has been shown previously for copper [72][73][74][75][76]. After the deposition of the sacrificial elements, the redox replacement process is followed and the dendritic structure remains as tellurium replaces the sacrificial elements on the electrode surface wherever they have been deposited, i.e.…”

“…In the co-electrodeposition process, over the limiting current density, the metal reduction occurs along with the evolution of hydrogen. The resulting hydrogen evolution and effect of overpotential cause the dendrite growth according to the dynamic hydrogen bubble template (DHBT) theory and direct the Cu–Co electrodeposition via the following reactions (eqs and ): , Upon applying the high negative potential (CED), Cu–Co alloy nucleation begins from Cu–Co precursor ions on a Ni foam substrate and the diffusion-limted growth promotes the successive growth of Cu–Co nanonodule seeds. The high surface and activation energy of nodule seeds extend the anisotropic growth and result in the dendrite architecture .…”

“…Indeed, zinc dendrites accelerate growth at critical overpotentials, while several parameters e.g. zincate concentration, local current density and temperature have also affect the initiation of the growth [15]. Several mechanisms have been proposed to describe dendrite formation during the dissolutionelectrodeposition processes.…”
