“…Thermodynamically it is favorable for the crystalline nanoparticles to aggregate epitaxially; such growth behavior and mechanism have been well reported in literature. [66,67] [69] Ni nanorod arrays were first grown by the templatebased electrochemical deposition. In the second step, the hydrated vanadium pentoxide shell was deposited onto the surface of nickel nanorods through sol electrophoretic deposition.…”

Nanostructured materials lie at the heart of fundamental advances in efficient energy storage and/or conversion, in which surface processes and transport kinetics play determining roles. This Review describes some recent developments in the synthesis and characterization of nanostructured cathode materials, including lithium transition metal oxides, vanadium oxides, manganese oxides, lithium phosphates, and various nanostructured composites. The major goal of this Review is to highlight some new progress in using these nanostructured materials as cathodes to develop lithium batteries with high energy density, high rate capability, and excellent cycling stability resulting from their huge surface area, short distance for mass and charge transport, and freedom for volume change in nanostructured materials.

“…Both energy density and power density of such nanocable-array electrodes are higher than those of single-crystal V 2 O 5 nanorod array and sol-gel-derived V 2 O 5 film. Such significant improvement in electrochemical performance is due to the large surface area and short diffusion lengths offered by the V 2 O 5 · nH 2 O shell [13]. Chou et al reported V 2 O 5 nanomaterials including nanoribbons, nanowires, and microflakes by an ultrasonic assisted hydrothermal method.…”

One-dimensional (1-D) nanomaterials with superior specific capacity, higher rate capability, better cycling peroperties have demonstrated significant advantages for high-performance Li-ion batteries and supercapacitors. This review describes some recent developments on the rechargeable electrodes by using 1-D nanomaterials (such as LiMn2O4 nanowires, carbon nanofibers, NiMoO4 · nH2O nanorods, V2O5 nanoribbons, carbon nanotubes, etc.). New preparation methods and superior electrochemical properties of the 1-D nanomaterials including carbon nanotube (CNT), some oxides, transition metal compounds and polymers, and their composites are emphatically introduced. The VGCF/LiFePO4/C triaxial nanowire cathodes for Li-ion battery present a positive cycling performance without any degradation in almost theoretical capacity (160 mAh/g). The Si nanowire anodes for Li-ion battery show the highest known theoretical charge capacity (4277 mAh/g), that is about 11 times lager than that of the commercial graphite (∼372 mAh/g). The SWCNT/Ni foam electrodes for supercapacitor display small equivalent series resistance (ESR, 52 mΩ) and impressive high power density (20 kW/kg). The advantages and challenges associated with the application of these materials for energy conversion and storage devices are highlighted.

“…No electron diffraction pattern in TEM was observed, which suggests the amorphous nature of these nanotubes. Figure 6 shows the SEM micrographs of Ni nanorod arrays and Ni-V 2 O 5 core-shell nanocable arrays [28]. Ni nanorod arrays were grown in PC membrane by electrochemical deposition from nickel sulfate solution.…”

Abstract. This paper introduces a process for the growth of oxide nanorod, nanotube, and nanocable arrays that combines sol preparation and template-based electrophoretic deposition. Examples are shown that the sol electrophoretic deposition is an effective method for the formation of polycrystalline and single crystal oxide nanorod arrays, nanotube arrays and conformal coating of thin films of oxides on metal nanorods to produce metal-oxide core-shell nanocable arrays.
