Constructing an ion‐oriented channel on a zinc electrode through surface engineering

The inherent shortcomings of a zinc anode in aqueous zinc-ion batteries (ZIBs) such as dendrites and side reactions severely limit their practical application. Herein, to address these issues, an ion-oriented transport channel constructed by graphdiyne (GDY) nanowalls is designed grown situ on the surface electrode. vertically stacked GDY with unique hierarchical porous structure mechanical properties form nanomesh-like interface electrode, acting channel, which can efficiently confine segmented growth metal microscopic regions hundreds nanometers. In those regions, uniform domain current density effortlessly maintained compared large area, thereby inhibiting effectively. Besides, due presence modified demonstrates long-term stable plating/stripping performance for more than 600 h at 1 mAh cm−2 electrolyte. addition, full-cells coupled MnO2 show high specific capacity power density, well excellent cycling stability retention 82% after 5000 cycles A g−1. This work provides feasible accessible engineering approach modify electrode confined dendrite-free deposition ZIBs.
