A schematic diagram of electrodeposited-hydrothermal device used in this study is shown in Fig. 1. Two Ti foils are used as electrodes (positive and negative electrodes), and the device is sealed without any gas leakage during the whole deposition reaction. The fabrication process of β-Na0.33V2O5 nanowire film on the negative Ti foil involves three aspects. A layer of sparse nanowires grows on the negative Ti foil with sufficient space between adjacent nanowires. Newly grown nanowires fill into

A novel electrodeposited-hydrothermal method has been developed to fabricate high-density β-Na0.33V2O5 nanowire film on a metal current collector (Ti foil). The morphology, crystal structure, and the effects of deposition voltage, temperature and time on the prepared samples were tested and presented in detail. The thickness of the β-Na0.33V2O5 nanowire film was ∼10.5 μm under experimental conditions of 5 h time, 2.5 V voltage, and 90 °C temperature. When the β-Na0.33V2O5 nanowire film was coated with polypyrrole and served as a cathode of lithium-ion battery, it exhi...
