Tuning Zn‐Ion Solvation Chemistry with Chelating Ligands toward Stable Aqueous Zn Anodes

Advanced Materials, 2022
AbstractChanging the solvation sheath of hydrated Zn ions is an effective strategy to stabilize Zn anodes to obtain a practical aqueous Zn‐ion battery. However, key points related to the rational design remain unclear including how the properties of the solvent molecules intrinsically regulate the solvated structure of the Zn ions.

Surface and Interface Engineering of Zn Anodes in Aqueous Rechargeable Zn‐Ion Batteries

Small, 2022
AbstractRechargeable zinc‐ion batteries (ZIBs) have shown great potential as an alternative to lithium‐ion batteries. The ZIBs utilize Zn metal as the anode, which possesses many advantages such as low cost, high safety, eco‐friendliness, and high capacity.

Strategies for Optimizing the Zn Anode/Electrolyte Interfaces Toward Stable Zn‐Based Batteries

Small Methods, 2023
AbstractAqueous rechargeable Zn‐ion batteries (ARZIBs) have attracted extensive attention because of the advantages of high energy density, high safety, and low cost. However, the commercialization of ARZIBs is still challenging, mainly because of the low efficiency of Zn anodes. Several undesirable reactions (e.g., Zn dendrite and byproduct formation)

Luminescence properties of anodically etched porous Zn

Applied Surface Science, 2000
Anodization of Zn in HF/ethanol and NaOH solution yields porous structure, which luminesces in the visible region. It is observed that the luminescence properties of these samples have been found quite different. The p-Zn prepared in NaOH displays two luminescence peaks near 420 and 520 nm. On the contrary, the p-Zn prepared in HF displays luminescence

Smart Self‐Healing Anode/Electrolyte Interphases for Stabilizing Zn Anode

Advanced Materials
AbstractThe rational design of Zn anode/electrolyte interphases (AEIs) is an effective strategy for regulating the Zn2+ stripping/plating process, as well as suppressing the interfacial side reactions. However, the formation of defects during the cycling process is still inevitable, and the exacerbation of defects would lead to the failure of the ...

Anodic Behaviour of Electrodeposited Zn-Sn Alloys

Transactions of the IMF, 1998
SummaryThe paper discusses the anodic behaviour of the electrodeposited alloys Zn-15%Sn in comparison with pure Zn coatings in 0.5M Na2SO4 and 5% NaCI. A passive state in 0.5M Na2SO4 medium was registered for the alloy while in 5% NaCI the typical passive state was not observed.

Achieving high-durability aqueous Zn-ion batteries enabled by reanimating inactive Zn on Zn anodes

Journal of Colloid and Interface Science
The heavy by-products generated on Zn anode surface decrease the active surface of Zn anodes and thus induce uneven Zn deposition, seriously reducing the service life of aqueous Zn-ion batteries (AZIBs). Herein, we propose an elimination strategy enabled by the coordination chemistry to dissolve the main by-products (Zn4SO4(OH)6·xH2O).
