Stable Zn Anodes with Triple Gradients

Advanced Materials, 2022
AbstractAqueous zinc‐ion batteries are highly desirable for sustainable energy storage, but the undesired Zn dendrites growth severely shortens the cycle life. Herein, a triple‐gradient electrode that simultaneously integrates gradient conductivity, zincophilicity, and porosity is facilely constructed for a dendrite‐free Zn anode. The simple mechanical

Dynamic Biomolecular “Mask” Stabilizes Zn Anode

Small, 2022
AbstractZn anode is confronted with serious Zn dendrite growth and water‐induced parasitic reactions, which severely hinders the rapid development and practical application of aqueous zinc metal batteries (AZMBs). Herein, inspired by sodium hyaluronate (SH) biomolecules in living organisms featured with the functions of water retention, ion‐transport ...

Leveling the Zn Anode by Crystallographic Orientation Manipulation

Nano Letters, 2023
Dendrite growth and corrosion of Zn metal anodes result in the limited reversibility of aqueous Zn metal batteries (ZMBs), hindering their prospects as large-scale energy storage devices. Inspired by the similarity of conventional electroplating industrial engineering and Zn deposition in ZMBs, we tend to utilize a low-cost leveling agent (LEA), 1,4 ...

Regulating the Interfacial Charge Density by Constructing a Novel Zn Anode‐Electrolyte Interface for Highly Reversible Zn Anode

Chemistry – A European Journal, 2023
AbstractAqueous zinc‐ion batteries (AZIBs) have attracted considerable attention. However, due to the uneven distribution of charge density at Zn anode‐electrolyte interface, severe dendrites and corrosion are generated during cycling. In this work, a facile and scalable strategy to address the above‐mentioned issues has been proposed through ...

The Effect of Tellurium on the Al–Zn–In Anode

Journal of The Electrochemical Society, 2011
The effects of tellurium as the alloying element on the Al―Zn―In sacrificial anodes have been investigated in NaCl solution. Scanning electron microscopy, energy-dispersive x-ray analysis, and inductively coupled plasma mass-spectrometry have been employed to study the morphology and corrosion behavior of improved anodes.

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 ...

Fulfilling the High Capacity of Zn Anodes in Rechargeable Alkaline Zn Batteries

ECS Meeting Abstracts, 2023
A Zn anode in an alkaline electrolyte is often discharged to a shallow depth for an adequate cycle life. It limits the overall cell energy density and undermines its competitiveness against ever-improving lithium-ion cells. Our lab has been pushing the capacity limit of the alkaline Zn anode by understanding its failure mechanism and designing ...
