Surface Engineering on Zinc Anode for Aqueous Zinc Metal Batteries

ChemSusChem
AbstractRechargeable aqueous zinc metal batteries (AZMBs) are considered as a potential alternative to lithium‐ion batteries due to their low cost, high safety, and environmental friendliness. However, the Zn anodes in AZMBs face severe challenges, such as dendrite growth, metal corrosion, and hydrogen evolution, all of which are closely related to the

Oriented Metal Stripping for Highly Reversible Zinc Anode

Small
Abstract Aqueous zinc metal batteries are a viable candidate for next‐generation energy storage systems, but suffer from poor cycling efficiency of the Zn anode. Emerging approaches aim to regulate zinc plating behavior to suppress uncontrolled dendrites, while the stripping process is seldom considered.

Enabling uniform zinc deposition by zwitterion additives in aqueous zinc metal anodes

Journal of Materials Chemistry A, 2023
This article proposes a new electrolyte engineering strategy with “zwitterion” molecules, which reduce side reactions by adsorbing onto the zinc surface. The 6-aminohexanoic acid enables uniform zinc deposition and reduces zinc dendrite growth.

Chemical Enhancement of Metallized Zinc Anode Performance

CORROSION 1998, 1998
Abstract Galvanic current delivered to reinforced concrete by a metallized zinc anode was studied relative to the humidity of its environment and periodic direct wetting. Current decreased quickly at low humidity to values unlikely to meet accepted cathodic protection criteria, but could be easily restored by direct wetting of the anode.

Pre‐Corrosion of Zinc Metal Anodes for Enhanced Stability and Kinetics

Small
Abstract Non‐uniform zinc plating/stripping in aqueous zinc‐ion batteries (ZIBs) often leads to dendrites formation and low Coulombic efficiency (CE), limiting their large‐scale application. In this study, a pre‐corroded Zn (PC‐Zn) anode with 3D ridge‐like structure is constructed by a facile solution etching in ...

Organic Cations Texture Zinc Metal Anodes for Deep Cycling Aqueous Zinc Batteries

Advanced Materials
AbstractManipulating the crystallographic orientation of zinc (Zn) metal to expose more (002) planes is promising to stabilize Zn anodes in aqueous electrolytes. However, there remain challenges involving the non‐epitaxial electrodeposition of highly (002) textured Zn metal and the maintenance of (002) texture under deep cycling conditions.

Design Strategies toward High‐Utilization Zinc Anodes for Practical Zinc‐Metal Batteries

Chemistry – A European Journal
AbstractAqueous Zn‐metal batteries (AZMBs) hold a promise as the next‐generation energy storage devices due to their low cost and high specific energy. However, the actual energy density falls far below the requirements of commercial AZMBs due to the use of excessive Zn as anode and the associated issues including dendritic growth and side reactions ...

Optimization of the Zinc Deposition Interface by Sn Nanoparticles for Fast-Charging Zinc Metal Anodes

Langmuir
The electrodeposition behavior of zinc metal anodes critically correlates with the electrode surface properties. The tendency for inhomogeneous deposition of zinc is more severe, especially under high current density. Herein, the surface structure of zinc and zinc deposition substrates is reconstructed with a uniform metal tin (Sn) coating via a simple
