“…Its potentially high surface area and prospective intercalation properties encourage the reassessment on Li-ion storage [29,[32][33][34][35] as well as further modification of nanostructures into nanotubes [36,37]. TiO 2 (B) is currently termed an "energy material" [38].…”

TiO 2 (B) and TiO 2 anatase nanowires were prepared at 150• C for 120 h by a hydrothermal method followed by calcination in air at 400• C for 2 h and at 700 • C for 2 h for TiO 2 (B) and TiO 2 anatase, respectively. Although dye-sensitized solar cells (DSC) with fully nanowire electrodes showed a rather low light-to-electricity conversion efficiency of 1.33 % for TiO 2 (B) and 2.42% for TiO 2 anatase, 10 wt % nanowire-dispersed electrodes in a P-25 TiO 2 -nanoparticle matrix demonstrated improved efficiency of 6.17 % for TiO 2 (B) and 6.53% for TiO 2 anatase, these exceeding that of pure P-25 electrodes in this work (η=5.59%). The dominant mechanisms of the improvement at 10 wt% for the two different polymorphs are thought to be different, i.e., a light-scattering and film-thickness increment for the TiO 2 (B) system, whereas there is an improved conduction path through the matrix for the TiO 2 anatase system.

“…35 37 % (Table 1). Lithium intercalation into trapped sites, side reactions of lithium with some H 2 O molecules adsorbed on the TiO 2 [6,7,29], the formation of a very thin disordered layer at the electrode surface [9] and poor intrinsic electronic conductivity [30] with cubic structure [31]. On the basis of these observations, in our electrode prepared at 400ºC, which gave an X-ray amorphous character, a plateau at 0.75 V is observed that may be assigned to the formation of very small crystallites of Li 2 Ti 2 O 4 .…”

A 3D mesoporous TiO 2 material with well-developed mesostructure is prepared in the form of a binderless thin (100 nm) film and studied as potential candidate for the negative electrode in lithium micro-batteries. By appropriate thermal treatments, the selected crystal structure (anatase, rutile, or amorphous), and micro-/mesostructure of the materials was obtained. An extended plateau with at about 0.75 V was found for an X-ray amorphous TiO 2 sample (400 ºC) which can be tentatively assigned to the irreversible formation of cubic Li 2 Ti 2 O 4 . The effects of voltage window and prelithiation treatment improved first cycle reversibility up to 86 % and capacity retention of 90 % over 100 cycles. This study highlights the flexibility of the potential window to which the electrode can operate. Maximum capacity values over 100 cycles of 470 μA h cm 2 μm 1 and 177 μA h cm 2 μm 1 are obtained for voltage ranges of 0.1 2.6 V and 1.0 2.6 V, respectively. The observed values are between 6 and 2 times higher than those obtained for films with 600 nm (80 μAh cm -2 μm -1 ) and 900 nm (92 μAh cm -2 μm -1 ) lengths. This indicates that 100 nm thin TiO 2 films with high accessibility show finite-length type diffusion which is interesting for this particular application.
