This research evaluates the impact of nanowire morphology and transition-metal doping to vanadium oxides as the positive electrode material on the performance of rechargeable aqueous zinc-ion batteries. It was found that both the wire morphology and Cu doping enhanced the cycle stability and specific capacity of the cathode. The improvement is ascribed to the wire morphology and Cu doping for attaining more mechanical stability, less morphology change and fewer parasitic reactions, and more facile Zn2+ insertion/extraction.
