Growth of zinc dendrites in acidic zinc chloride solutions

Electrochimica Acta, 1982
Abstract The heights and widths of zinc dendrites were measured in pure zinc chloride solutions in the concentration and pH range prevailing in zinc-halogen load leveling batteries. At constant overpotential the height increases linearly with time, indicating a constant growth rate.

The Mechanism of the Dendritic Electrocrystallization of Zinc

Journal of The Electrochemical Society, 1969
Measurements have been made of the growth rate of zinc dendrites in alkaline zincate solutions as a function of overpotential (η), concentration , and temperature . The tip radii have been measured by electron microscopy. At constant potential, an initiation time of between 5 and 100 min is observed, depending on η, c, and T.

Cooperativity in Chiroptical Sensing with Dendritic Zinc Porphyrins

Journal of the American Chemical Society, 2005
Zinc porphyrin-appended dendrimers, 12PZn, 18PZn, 24PZn, and 36PZn, containing 12, 18, 24, and 36 zinc porphyrin units, respectively, were synthesized using zinc porphyrin dyad (2PZn) and triad (3PZn) as precursors. Although these dye-functionalized dendrimers all serve as chiroptical sensors for an asymmetric bipyridine (RR- and SS-Py2), the sensing ...

Review of zinc dendrite formation in zinc bromine redox flow battery

Renewable and Sustainable Energy Reviews, 2020
Abstract The zinc bromine redox flow battery (ZBFB) is a promising battery technology because of its potentially lower cost, higher efficiency, and relatively long life-time. However, for large-scale applications the formation of zinc dendrites in ZBFB is of a major concern.

Dendrite Suppression Membranes for Rechargeable Zinc Batteries

ACS Applied Materials & Interfaces, 2018
Aqueous batteries with zinc metal anodes are promising alternatives to Li-ion batteries for grid storage because of their abundance and benefits in cost, safety, and nontoxicity. However, short cyclability due to zinc dendrite growth remains a major obstacle.

The critical overpotential for zinc dendrite formation

Journal of Applied Electrochemistry, 1979
The critical overpotential for zinc dendrite growth is determined as 173 mV by the method described by Popovet al. [1]. It was shown that this procedure can be applied successfully to metal deposition processes when there is a large codeposition of hydrogen.

Revealing the Two‐Dimensional Surface Diffusion Mechanism for Zinc Dendrite Formation on Zinc Anode

Small, 2021
AbstractAqueous zinc‐ion battery is regarded as one of the promising devices for large‐scale energy storage systems owing to its high safety, cost‐effectiveness, and competitive electrochemical properties. However, the dendrite growth on zinc metal anodes dramatically hinders its further practical applications, and the internal mechanism of dendrite ...
