“…As mentioned above, titanium oxides are candidates high-voltage anode materials for LIBs and have been widely studied. 9) TiO 2 (B) has been studied not only as high-voltage anode material but also as high-power-capable electrode material. M. Zukalová et al reported that the lithium intercalation reaction into TiO 2 (B) synthesized by a specific condition is not limited by the diffusion of lithium ions in the solid phase but is governed by a pseudocapacitive faradaic process.…”

The lithium intercalation properties of alkai tetratitanate (Li 2 Ti 4 O 9 ·1.1H 2 O, Na 1.5 H 0.5 Ti 4 O 9 ·0.53H 2 O) and octatitanate with various amounts of hydrated water (H 2 Ti 8 O 17 ·nH 2 O; n = 0.41, 0.96, 1.5) were examined. Alkali tetratitanates were obtained by ion exchange of the starting tetratitanate hydrate (H 2 Ti 4 O 9 ·1.9H 2 O) and subsequent heat treatment. Octatitanates were prepared by heat treatment of the starting tetratitanate hydrate. The prepared titanates exhibited a reversible capacity corresponding to a reduction of half of the Ti atoms from a tetravalent state to a trivalent state. This indicates that the reaction activity of the host oxide layer of titanates is not affected by the condensation reaction during transformation from tetratitanate to octatitanate. H 2 Ti 8 O 17 ·0.41H 2 O showed the largest capacity and best rate capability among the prepared titanates; this is because of its relatively small chemical formula weight per Ti atom. The difference in the rate capability of the titanates is caused by the steric effects of hydrated water molecules in the lithium diffusion path along the b-axis.

a b s t r a c tAu nano particles (NPs) were deposited on vertically grown TiO 2 nanorod arrays on FTO substrate by hydrothermal process. Metal nanoparticles were loaded onto the surface of TiO 2 nanorods via photochemical reduction process under ultraviolet irradiation. X-ray diffraction (XRD), electron microscopy (FESEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) analysis were used to characterize the as-prepared Au/TiO 2 nanorod composites. Current density-voltage (J-V) measurements were obtained from a two-electrode sandwich type cell. The presence of Au nanoparticles can help the electron-hole separation by attracting photoelectrons. Addition of Au nanoparticles to the TiO 2 nanorod significantly increased the fill factor and J SC (short circuit current density). The application of Au NPs TiO 2 nanorods in improving the performance of DSSCs is promising.

A composite of aminosilane-grafted TiO 2 (TA) and graphene oxide (GO) was prepared via a hydrothermal process. The TiO 2 /graphene oxide-based (TA/GO) anode was investigated in an ionic liquid electrolyte (0.7 M lithium bis(trifluoromethanesulfonyl)imide (LiNTf 2 )) in ionic liquid (N-methyl-N-propylpyrrolidinium bis(trifluoromethanesulfonyl)imide (MPPyrNTf 2 )) at room temperature and in sulfolane (1 M lithium hexafluorophosphate (LiPF 6 ) in tetramethylene sulfolane (TMS)). Scanning and transmission electron microscopy (SEM and TEM) observations of the anode materials suggested that the electrochemical intercalation/deintercalation process in the ionic liquid electrolyte with vinylene carbonate (VC) leads to small changes on the surface of TA/GO particles. The addition of VC to the electrolyte (0.7 M LiNTf 2 in MPPyrNTf 2 + 10 wt.% VC) considerably increases the anode capacity. Electrodes were tested at different current regimes in the range 5-50 mA g . The decrease in anode capacity with increasing current rate was interpreted as the result of kinetic limits of electrode operation. A much lower capacity was observed for the system TA/GO│1 M LiPF 6 in TMS + 10 wt.% VC│Li.
