“…As shown in Fig. 2b, we observed five characteristic Raman scattering peaks at 145 (Eg), 198 (Eg), 398 (B1g), 516 (A1g + B1g), and 638 (Eg) cm −1 corresponding to the peaks for tetragonal anatase TiO 2 crystals30 and the typical D and G bands for rGO31. Because of the much stronger reducing atmosphere of the H 2 /Ar mixture compared to Ar, the intensity of the G band in the spectrum of rGO/TiO 2 -7ArH is greater than that in the spectrum of rGO/TiO 2 -7Ar.…”

Through electrostatic interaction and high-temperature reduction methods, rGO was closely coated onto the surface of TiO2 nanotubes. Even at a high temperature of 700 °C, the nanotube morphology of TiO2 (anatase) was preserved because of the assistance of rGO, which provides a framework that prevents the tubes from breaking into particles and undergoing a phase transformation. The rGO/TiO2 nanotubes deliver a high capacity (263 mAh g−1 at the end of 100 cycles at 0.1 A g−1), excellent rate performance (151 mAh g−1 at 2 A g−1 and 102 mAh g−1 at 5 A g−1), and good cycle stability (206 mAh g−1 after 500 cycles at 0.5 A g−1). These characteristics arise from the GO/TiO2 nanotubes’ advanced structure. First, the closely coated rGO and Ti3+ in the tubes give rise to a high electro-conductivity of the nanotubes. Additionally, the Li+ ions can rapidly transfer into the electrode via the nanotubes’ empty inner diameter and short tube wall.

Li 4 Ti 5 O 12 nanopowder was successfully synthesized by simple peroxo-solution growth technique. The physicochemical properties of synthesized powders were studied by powder X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy and Scanning electron microscopy. The effect of calcination on structure, morphology and the electrochemical performances of Li 4 Ti 5 O 12 have also been investigated. The electrochemical property of the Li 4 Ti 5 O 12 was analyzed by galvanostatic charge/discharge test. The storage capacity of 90.27 mAh g -1 was achieved for Li 4 Ti 5 O 12 nanopowder.

“…In theoretical models that include the effects of these ions, they are usually considered as surface-adsorbates. On the other hand, from battery research, we now know that insertion of large amounts of metal atoms into TiO 2 is possible [16,[46][47][48]. It has also been reported that anatase TiO 2 anodes in DSSC can undergo a phase transition to the B phase [49].…”

Solar-to-electricity energy conversion and large scale electricity storage technologies are key to achieve a sustainable development of society. For energy conversion, photoelectrochemical solar cells were proposed as an economic alternative to the conventional Si-based technology. For energy storage, metal-ion batteries are a very promising technology. Titania (TiO 2 ) based anodes are widely used in photoelectrochemical cells and have recently emerged as safe, high-rate anodes for metal-ion batteries. In both applications, titania interacts with electrolyte species: molecules and metal ions. Details of this interaction determine the performance of the electrode in both technologies, but no unified theoretical description exists, e.g., there is no systematic description of the effects of Li, Na insertion into TiO 2 on solar cell performance (while it is widely studied in battery research) and no description of effects of surface adsorbents on the performance of battery anodes (while they are widely studied in solar cell research). In fact, there is no systematic description of interactions of electrolyte species with TiO 2 of different phases and morphologies. We propose a computation-focused study that will bridge the two fields that have heretofore largely been developing in parallel and will identify improved anode materials for both photoelectrochemical solar cells and metal-ion batteries.
