Tunnel-type vanadium oxides are promising cathodes for aqueous zinc ion batteries. However, unlike layer-type with adjustable layer distances, enhancing ion-transport kinetics in tunnels characterized by fixed sizes poses a considerable challenge. This study highlights that the macroscopic arrangement of electrode crucially determines tunnel orientation, thereby influencing transport. By changing material morphology, orientation can be optimized to facilitate rapid diffusion. In proof-of-concept demonstration, it is revealed (00l) facets-dominated VO

Abstract Layered materials are characterized by strong in‐plane covalent chemical bonds within each atomic layer and weak out‐of‐plane van der Waals (vdW) interactions between adjacent layers. The non‐bonding nature neighboring layers naturally results in a vdW gap, which enables the insertion of guest species into interlayer gap. Rational design regulation nanochannels crucial for converting these layered their 2D derivatives ion separation membranes or battery electrodes. Herein, based on latest progress derivative nanosheets, various engineering methods briefly introduced, along with effects intercalated crystal structure coupling host materials. Their applications energy storage fields then summarized, focus to improve selective transport performance. Finally, future research opportunities challenges this emerging field comprehensively discussed.
