DFG- LIDINAM (HA 6966/1-2) (WI 3600/4-2) - Lithium-Diffusion in oxide nanotubes and in ordered nanostructured as well as mesostructured layered materials (DFG, FOR 1277, TP7, WI 3600 4-2)

In the present project, Li diffusion and transport parameters, respectively, of nanostructured oxides such as TiO2 and SnO2 (ordered mesoporous materials, nanocrystallites of just a few nm diameter, nanosheets) are planned to be studied by impedance and NMR spectroscopy. In particular, the latter offers a large set of complementary techniques to study both micro- and macroscopic Li dynamics on a broad time scale including extremely slow and very fast Li motions. Moreover, NMR spin-lattice relaxation rates, when measured as a function of frequency in the high-T limit, are sensitive to the dimensionality of a given diffusion process.
