“…Currently, manganese- [ 20 ], vanadium- and Prussian blue analogue (PBA)-based cathodes have been proven to be typical cathode materials for ZIBs [ 21 ]. Among them, manganese- [ 22 , 23 ] and PBA-based [ 24 ] materials have ideal charging and discharging platforms [ 25 ] but usually suffer from an insufficient long-term cycling ability [ 26 ] and low reversible capacity [ 27 ] because of their intrinsic unstable structural characteristics [ 28 , 29 , 30 ]. Therefore, vanadium-based materials with a high theoretical specific capacity and adjustable ion-transfer channels will most likely become promising candidates for high-performance cathodes in ZIBs [ 31 ].…”

Aqueous zinc-ion batteries (ZIBs) have significant potential for large energy storage systems because of their high energy density, cost-effectiveness and environmental friendliness. However, the limited voltage window, poor reaction kinetics and structural instability of cathode materials are current bottlenecks which contain the further development of ZIBs. In this work, we rationally design a Ni-doped V2O5@3D Ni core/shell composite on a carbon cloth electrode (Ni-V2O5@3D Ni@CC) by growing Ni-V2O5 on free-standing 3D Ni metal nanonets for high-voltage and high-capacity ZIBs. Impressively, embedded Ni doping increases the interlayer spacing of V2O5, extending the working voltage and improving the zinc-ion (Zn302+) reaction kinetics of the cathode materials; at the same time, the 3D structure, with its high specific surface area and superior electronic conductivity, aids in fast Zn302+ transport. Consequently, the as-designed Ni-V2O5@3D Ni@CC cathodes can operate within a wide voltage window from 0.3 to 1.8 V vs. Zn30/Zn302+ and deliver a high capacity of 270 mAh g−1 (~1050 mAh cm−3) at a high current density of 0.8 A g−1. In addition, reversible Zn2+ (de)incorporation reaction mechanisms in the Ni-V2O5@3D Ni@CC cathodes are investigated through multiple characterization methods (SEM, TEM, XRD, XPS, etc.). As a result, we achieved significant progress toward practical applications of ZIBs.
