Rational Design of Ni-Doped V₂O₅@3D Ni Core/Shell Composites for High-Voltage and High-Rate Aqueous Zinc-Ion Batteries.

ABSTRACT: 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
