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.

Aqueous zinc-ion batteries (AZIBs), featuring low cost and high safety, have become a research hotspot in recent years. However, the low Zn stripping/plating reversibility, caused by dendritic growth, harmful side reactions, and Zn metal corrosion, severely influences the applicability of AZIBs.

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.

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.

In this work, the possibility to make small, handy but efficient Zn-air batteries has been studied. Battery anode has been constructed by dendrite-free Zn electrodeposition on conductive substrates made of either carbon cloth or brass. Brass was an alloy containing 71% Cu and 21% Zn. Zn electrodeposition has been monitored by applying several (negative)

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
