Electrochimica Acta, 133 570-577.Tuning three-dimensional TiO2 nanotube electrode to achieve high utilization of Ti substrate for lithium storage AbstractThree-dimensional (3D) TiO2 nanotube arrays grown on Ti mesh were prepared via the anodization process. The diameters of the Ti and TiO 2/Ti wires and the length of the TiO2 nanotubes have linear relationships with the anodization processing time. When the anodization processing time is 600 min, the TiO2/Ti mesh anode materials showed good capacity retention and high specific area capacity, without the need for a current collector or binder, due to their high surface area, high substrate utilization, and large active material loading rate per unit area. At the current density of 50 μA cm-2, TiO2/Ti mesh with 600 min anodization processing time has a stable discharge platform at 1.78 V, and the specific area capacity is 1745.5 μAh cm-2 over 100 cycles. By tuning the geometric parameters of the TiO2/Ti mesh and the anodization processing time, we can pave the way to finding TiO2/Ti mesh electrodes for lithium-ion batteries with high capacity per unit area and outstanding mechanical behaviour.Keywords substrate, three, lithium, dimensional, storage, achieve, tio2, ti, nanotube, utilization, high, electrode, tuning Disciplines Engineering | Physical Sciences and Mathematics Publication DetailsZhang, Z., Zeng, Q., Chou, S., Li, X., Li, H., Ozawa, K., Liu, H. & Wang, J.

With the assistance of nonionic surfactant (OP-10) and surface-selective surfactant (CH 3 COOH), anatase TiO 2 was prepared as an anode material for lithium ion batteries. The morphology, the crystal structure, and the electrochemical properties of the prepared anatase TiO 2 were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), electrochemical impedance spectroscopy (EIS), and galvanostatic charge and discharge test. The result shows that the prepared anatase TiO 2 has high discharge capacity and good cyclic stability. The maximum discharge capacity is 313 mAh⋅g −1 , and there is no significant capacity decay from the second cycle.

TiO 2 -B nanowires with remarkable mesoporous structure via a template-free low-temperature hydrothermal fabrication route have been prepared by employing titanium glycolate (TG) as a precursor. The formation of mesopores in TiO 2 -B nanowires is caused by the evolvement of vacancies derived from the chains of TG. The product is characterized by X-ray diffraction, Raman spectroscopy, nitrogen adsorption-desorption, and electron microscopy. The lithium-ion storage capacity of mesoporous TiO 2 -B nanowires is evaluated by galvanostatic measurements. The initial discharge-charge capacities of the material are 310 and 231 mAh g -1 at a current density of 50 mA g -1 , respectively. A discharge capacity of 198 mAh g -1 is still retained when charge-discharge at 1.0 A g -1 for 50 cycles, demonstrating the high-rate performance and good cycle ability. The large reversible capacity, high-rate performance, and good cycle ability of the material are attributed to unique mesoporous structure and intrinsic properties of the TiO 2 -B nanowires. The mesoporous TiO 2 -B nanowire synthesized from TG is promising for use as an anode material for lithium-ion batteries with high power and energy densities.
