“…For the galvanostatic cycling tests, the potential was limited to 1.5-3 V vs. Li/Li + , to avoid Li insertion into the rutile phase and non-faradaic surface reactions [9,13]. The capacity evolution at a quite high rate of 5 C (0.840 A g −1 ) for the commercial TiO 2,com samples compared with the TiO 2,nano sample is shown in Fig.…”

“…However, too small particles are generally hampered by strong charge irreversibility due to parasitic surface reactions [9]. In this context, mesoporous materials have received a particular attention since they are effective in increasing the lithium insertion capacity of electrode materials, especially at high charge/discharge rates, with excellent cycling stability [10][11][12][13]. On the other hand, different strategies have been investigated in order to improve the material conductivity by adding conductive phases such as carbon, conductive polymers, or metals [14][15][16].…”

Several carbon-coated anatase TiO 2 samples have been prepared by impregnation with lactose as carbon precursor and annealed at different temperatures (650 and 700°C). X-ray diffraction was carried out to study the anatase to rutile phase transition and to evaluate the crystallite size. Scanning electron microscopy was utilized to evaluate the morphology, and transmission electron microscopy was used to show the distribution and nature of the carbon coating. The galvanostatic measurements and cyclic voltammetry revealed better kinetics, cycling stability, and high rate capacity for the carbon-coated materials when compared with the noncoated ones.

“…Titanium dioxide is abundant in nature and can be easily fabricated with low cost in addition to its chemical stability and various favorable physical properties, and thus has been extensively explored and studied for applications in energy conversion and storage [1][2][3]. For example, it has been widely studied as electrodes in dye-sensitized solar cells [4][5], biosensors [6][7], and lithium-ion batteries [8][9].…”

This particular difference is most probably a consequence of the low amount of active material deposited on the Ti current collector as compared with powder samples together with a low crystallite size in the films obtained at 400 ºC.…”

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.
