dc.description.abstract | A novel 3D nanostructured Fe3O4/Cu-cone arrays (Cu-CAs) anode is prepared by template-free chemical deposition of Cu-CAs on a flat Cu current collector followed by galvanostatic electrodeposition of polycrystalline Fe3O4 nanoparticles (NPs) and Fe3O4 nanoflakes (NFs) from electrolyte containing 0.1?M tri-ethanol-amine (TEA) and 0.2?M TEA, respectively. The developed anodes are characterized by X-ray diffraction, field emission scanning electron microscope, transmission electron microscopy and X-ray photoelectron spectroscopy. Galvanostatic charge/discharge tests are carried out to evaluate the cycling performance of all the anodes at a constant current density of 680?mA?g??1 and cyclic voltammetry measurements are performed to characterize the charge/discharge potentials. The Fe3O4 NPs/Cu-CAs anode fabricated by 90?s electrodeposition exhibits the best performance with a reversible discharge capacity of 442.96?mAh?g??1 after 100 cycles at 1 C-rate due to the optimal synergistic effect of crystallinity and reinforcement effect of Cu-CAs substrate. While the better performance of Fe3O4 NFs/Cu-CAs anode fabricated by 120?s electrodeposition is attributable to the enhanced surface porosity and reinforcement effect of Cu-CAs. However, the comparison between anodes electrodeposited with 0.1?M and 0.2?M TEA indicates that the reinforcement effect of Cu-CAs plays the dominant role in determining the cycling performance of developed Fe3O4/Cu-CAs anodes. ? 2017 Elsevier Ltd | - |
