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).

Maltose Additive Enables Compacted Deposition of Zn Ions for Stabilizing the Zn Anode

ACS Applied Materials & Interfaces
Aqueous zinc-ion batteries (AZIBs) have emerged as one of the most promising energy storage technologies due to their high safety and cost-effectiveness. However, several challenges associated with the Zn metal anode, such as dendrite growth, corrosion, and hydrogen evolution reaction (HER), have hindered further applications of AZIBs. Herein, maltose (

Multifunctional Separator for Zn Metal Anode Protection

ECS Meeting Abstracts
Lithium-ion batteries (LIBs) have issues such as the high cost of raw materials due to the use of rare metals such as Li and Co in the electrode and the risk of fire due to the use of organic electrolytes.[1] Zn-ion batteries (ZIBs) based on aqueous electrolytes are inexpensive (~US$2 kg-1) and safe for practical use.[2] In addition, the high ...
