Aqueous Zinc Metal Batteries with Anode Stabilized by Plasma Treatment

Energy Technology
Aqueous Zn batteries have recently attracted significant attention due to the various benefits offered by Zn metal anodes. However, the formation of dendrites and unwanted side reactions between the Zn anode and the aqueous electrolyte remain challenging problems. Herein, a straightforward plasma treatment that converts the surface of the Zn metal into

K+‐Triggered Defect Engineering and Proton‐Coupled Storage in V2O5·nH2O for Advanced Zn‐Ion Thin‐Film and Microbatteries

Advanced Science, EarlyView.
K+ pre‐intercalation in V2O5·nH2O induces interlayer contraction, oxygen‐vacancy formation, and mixed‐valence states, activating defect‐mediated proton‐dominated transport. This enables cooperative H+/Zn2+ storage with enhanced kinetics and stability. The resulting Zn‐based thin‐film and microbatteries deliver high areal energy and capacity, offering a
