英文摘要	The zinc metal is recognized as one of the most promising anodes for Zn-based batteries in an energy-storage system. However, the deposition and transfer of bivalent Zn2+ into the host structure suffer from sluggish kinetics accompanying the side-reactions at the interface. Herein, we report a new class of Zn anodes modified by a three-dimensional (3D) nanoporous ZnO architecture coating on a Zn plate (designated as Zn@ZnO-3D) prepared by in situ Zn(OH)42- deposition onto the surface. This novel structure has been proven to accelerate the kinetics of Zn2+ transfer and deposition via the electrostatic attraction toward Zn2+ rather than the hydrated one in the electrical double layer. As a consequence, it achieves an average 99.55% Zn utilization and long-time stability for 1000 cycles. Meanwhile, the Zn@ZnO-3D/MnO2 cell shows no capacity fading after 500 cycles at 0.5 A g-1 with a specific capacity of 212.9 mA h g-1. We believe that the mechanistic insight into the kinetics and thermodynamic properties of the Zn metal and the understanding of structure-interface-function relationships are very useful for other metal anodes in aqueous systems. © 2020 The Royal Society of Chemistry.
