Adhesive Molecular Protective Layer of a Zincophilic Ionic Liquid for Durable High‐Energy Zn‐Ion Batteries Open
The lifespan of Zn‐ion batteries (ZIBs) is severely hindered by dendritic Zn growth and side reactions. These drawbacks are exacerbated under practical conditions, such as high current density. Herein, an adhesive ionic liquid electrolyte …

Discovery of Dual‐Functional Amorphous Titanium Suboxide to Promote Polysulfide Adsorption and Regulate Sulfide Growth in Li–S Batteries Open
Lithium‐sulfur (Li–S) batteries are promising as next‐generation energy storage systems. Adsorbents for sulfide species are favorably applied to the cathode, but this substrate often results in a surface‐passivating lithium sulfide(Li 2 S)…

Complete encapsulation of sulfur through interfacial energy control of sulfur solutions for high-performance Li−S batteries Open
Significance Complete encapsulation of high-content sulfur into porous carbon or carbon composites is crucial for high-performance Li−S cells. However, the low-to-moderate compatibility of sulfur-dissolved solution with carbon causes diffi…

MnO2 Nanoflake-Shelled Carbon NanotubeParticles for High-Performance Supercapacitors Open
We\nintroduce MnO2 nanoflake/carbon nanotube (CNT) core–shell\nparticles for high-performance supercapacitors. The CNT particles\nprepared by drying the CNT-dispersed aerosol produce a tightly intertwined\nCNT assembly by internal capillar…
