Dendrites in Zn‐Based Batteries
Advanced Materials, 2020AbstractAqueous Zn batteries that provide a synergistic integration of absolute safety and high energy density have been considered as highly promising energy‐storage systems for powering electronics. Despite the rapid progress made in developing high‐performance cathodes and electrolytes, the underestimated but non‐negligible dendrites of Zn anode ...

Manipulating Uniform Nucleation to Achieve Dendrite-Free Zn Anodes for Aqueous Zn-Ion Batteries
ACS Applied Materials & Interfaces, 2021The essence of Zn dendrite formation is ultimately derived from Zn nucleation and growth during the repeated Zn plating/stripping process. Here, the nucleation process of Zn has been analyzed using ex situ scanning electron microscopy to explore the formation of the initial Zn dendrite, demonstrating that the formation of tiny protrusions (the initial ...

Nonlinear oscillations in electrochemical growth of Zn dendrites
Physical Review B, 1989Electrochemical deposition can produce interesting patterns ranging from random fractals to orderly dendrites. We have studied the electrical signals due to the deposition of Zn ions in a cell with ${\mathrm{ZnSO}}_{4}$ electrolyte. In the dendritic regime, the current (voltage) exhibits periodic oscillations with constant applied voltage (current ...

Dendritic growth of ZnS crystals
Acta Physica Academiae Scientiarum Hungaricae, 1965The dendritic growth of ZnS crystals in the form of long ribbons, plates and needles was observed when ZnS crystallized from liquid Ga. The cubic ribbons and plates propagated in the directions, the needles were hexagonal and their main propagation was parallel to the c-axis.

Resist-Dyed Textile Alkaline Zn Microbatteries with Significantly Suppressed Zn Dendrite Growth
ACS Applied Materials & Interfaces, 2019The progress of electronic textiles relies on the development of sustainable power sources without much sacrifice of convenience and comfort of fabrics. Herein, we present a rechargeable textile alkaline Zn microbattery (micro-AZB) fabricated by a process analogous to traditional resist-dyeing techniques.

Materials Research Bulletin, 2018
Abstract An electrodeposition-calcination route was designed for the preparation of Zn/ZnO dendrites in this work. Zn dendrites were first deposited at room temperature via a potentiostatic electrodeposition route at the potential of −1.5 V for 10 min. Then, Zn/ZnO dendrites were obtained through calcining Zn dendrites in air at 100–400 °C for 30 min.

The Dendrite Non-Homogeneity in Mg—Zn Alloys
Kristall und Technik, 1972AbstractThe distribution of Zn within the grains of MgZn alloys is studied in the case of maximum degree of zinc segregation within dendrites. The composition lines measured by microprobe analyzer are in good accordance with those theoretically predicted.

Synergistic Cooperation of Zn(002) Texture and Amorphous Zinc Phosphate for Dendrite-Free Zn Anodes
ACS Nano, 2023Zn anodes of aqueous Zn metal batteries face challenges from dendrite growth and side reactions. Building Zn(002) texture mitigates the issues but does not eradicate them. Zn(002) still faces severe challenges from corrosive electrolytes and dendrite growth, especially after hundreds of cycles.

Non-Dendritic Zn Electrodeposition Enabled by Zincophilic Graphene Substrates
ACS Applied Materials & Interfaces, 2019Rechargeable zinc (Zn) batteries suffer from poor cycling performance that can be attributed to dendrite growth and surface-originated side reactions. Herein, we report that cycling performance of Zn metal anode can be improved significantly by utilizing monolayer graphene (Gr) as the electrodeposition substrate.
