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 ...

Anodic oxidation of Mg–Cu and Mg–Zn alloys

Electrochimica Acta, 2004
Metastable, solid–solution Mg-0.8 at.% Cu and Mg-1.4 at.% Zn alloys have been anodized up to 250 V at 10 mA cm−2 in an alkaline phosphate electrolyte at 293 K in order to investigate the enriching of alloying elements beneath the anodic films. Rutherford backscattering spectroscopy (RBS) revealed enrichments to about 4.1×1015 Cu atoms cm−2 and 5.2×1015

The surface-modified effects of Zn anode with CuO in Zn-air batteries

Applied Surface Science, 2019
Abstract Copper oxide nanoparticles (CuO-NPs) can be used to prevent dendrite formation and increase the reversibility of Zn anode. The zinc surface was modified with CuO and the Cu source used was copper nitrate. It also contained 0.1 wt%, 0.5 wt%, 1.0 wt%, and 3.0 wt% CuO by weight of zinc.
