“…Then, the electrochemical growth of ZnO rods on Ti foils and on TiO 2 nanotubes has been studied. In agreement with previous works recently reported in the case of tin nanowire [41][42][43][44][45], we show that the titania nanotubes could be used as a guide layer to activate the electrochemical growth of vertical ZnO nanomaterials.…”

We report the ability to use TiO 2 nanotube as a guide layer to achieve the vertical growth of ZnO nanorods, in additive-free bath. First, we focused on the anodisation conditions (cell voltage and anodisation time) to produce TiO 2 nanotube thin films grown from a 1.5 µm thick Ti layer sputtered onto Si. Highly organised titania nanotubes were obtained in glycerol viscous electrolyte. In a second step, the electrochemical growth of ZnO grains has been investigated from a zinc nitrate bath at 70°C on both Ti foil and TiO 2 nanotubes. ZnO deposition mechanism has been highlighted through the electrochemical experiments in conjunction with XRD technique and scanning electron microscopy (SEM) examinations. On Ti foils, we show that addition of additives is required to obtain a highly oriented nanostructured ZnO deposit. On TiO 2 nanotubes, additives are not necessary to obtain such a deposit: Titania nanotubes can be used to guide the vertical growth of hybrid nano-architectured ZnO/TiO 2 electrode.

“…Due to the relatively large size of the reported SnO structures, their electrochemical properties are far away from being satisfied, due to the severe volume changes and the related pulverization problems. Ortiz et al used TNT arrays as a matrix to accommodate the large volume change of SnO . Composite materials consisting of either metallic Sn, or SnO nanowires have been grown on TiO 2 nanotubes by electrodeposition .…”

SnO(x) (x = 0, 1, 2) and TiO(2) are widely considered to be potential anode candidates for next generation lithium ion batteries. In terms of the lithium storage mechanisms, TiO(2) anodes operate on the base of the Li ion intercalation-deintercalation, and they typically display long cycling life and high rate capability, arising from the negligible cell volume change during the discharge-charge process, while their performance is limited by low specific capacity and low electronic conductivity. SnO(x) anodes rely on the alloying-dealloying reaction with Li ions, and typically exhibit large specific capacity but poor cycling performance, originating from the extremely large volume change and thus the resultant pulverization problems. Making use of their advantages and minimizing the disadvantages, numerous strategies have been developed in the recent years to design composite nanostructured Sn-Ti-O ternary systems. This Review aims to provide rational understanding on their design and the improvement of electrochemical properties of such systems, including SnO(x) -TiO(2) nanocomposites mixing at nanoscale and nanostructured Sn(x) Ti(1-x) O(2) solid solutions doped at the atomic level, as well as their combinations with carbon-based nanomaterials.

“…Particularly, better rate capability, capacity, and cycling behavior have been observed for self-organized nanostructures such as titania nanotubes (TiO 2 nt) [2-9]. However, when targeting 3D microbatteries, the conventional top-down approach to deposit solid electrolyte (e.g., lithium phosphorous oxynitride) [10-12] is not really suitable due to the accumulation of the electrolyte at the top of the nanotubes [13].…”

The highly conformal electrodeposition of a copolymer electrolyte (PMMA-PEO) into self-organized titania nanotubes (TiO2nt) is reported. The morphological analysis carried out by scanning electron microscopy and transmission electron microscopy evidenced the formation of a 3D nanostructure consisting of a copolymer-embedded TiO2nt. The thickness of the copolymer layer can be accurately controlled by monitoring the electropolymerization parameters. X-ray photoelectron spectroscopy measurements confirmed that bis(trifluoromethanesulfone)imide salt was successfully incorporated into the copolymer electrolyte during the deposition process. These results are crucial to fabricate a 3D Li-ion power source at the micrometer scale using TiO2nt as the negative electrode.
