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 ...

Compression of semisolid dendritic and non-dendritic ZnAl alloys at low strain rates
Materials Science and Engineering, 1984Abstract The behaviour of semisolid ZnAl alloys with a dendritic or a non-dendritic structure was studied in compression between two parallel plates. Small cylindrical specimens were deformed at constant strain rates ranging from 0.012 to 0.72 mm mm −1 s −1 and at various temperatures ranging from 350 to 443 °C.

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.

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.

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.

The dendritic morphology in Zn-Cd dilute alloys
Journal of Crystal Growth, 1972In Zn-Cd dilute alloys the transition from cells to dendrites is analyzed for increasing values of constitutional supercooling. The substructure evolution is through two simultaneous and continuous mechanisms: arm formation as a result of the node mechanism and cell elongation in a direction parallel to the basal plane.

Small
AbstractIn spite of extensive research and appreciable progress, in aqueous zinc‐ion batteries, Zn metal anode is struggling with low Zn utility and poor cycling stability. In this study, a 3D “electrochemical welding” composite electrode is designed by introduction of ZnO/C nanofibers film to copper foils as an anode according to pre‐electrodeposition

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.

A Heteroanionic Zinc Ion Conductor for Dendrite‐Free Zn Metal Anodes
Advanced Materials, 2023AbstractAlthough zinc‐based batteries are promising candidates for eco‐friendly and cost‐effective energy storage devices, their performance is severely retarded by dendrite formation. As the simplest zinc compounds, zinc chalcogenides, and halides are individually applied as a Zn protection layer due to high zinc ion conductivity.
