Amorphous and anatase TiO2 nanotube layers were synthesized by means of Ti foil anodic oxidation performed in ethylene glycol based electrolyte containing fluoride ions. A typical surface structure of TiO2 nanotubular layer, well aligned nanotubes with inner diameter of 70-100 nm and wall thickness of about 10-15 nm was obtained. Both amorphous and converted to anatase nanotube layers were mechanically stable and well adherent to the Ti current collector. The nanostructured Ti/TiO2 layers were tested as a current collector - anode material system for Li-ion intercallation in 1 M LiPF6 ethylene carbonate/dimethyl carbonate (EC:DMC) and in 1-buthyl-1-methyl pyrrolidinium is (trifluoromethyl) sulfonylimide ([BMP][TFSI]) containing 1 M Li[TFSI]. The potential window of [BMP][TFSI] measured on Ti current collector remains not considerably influenced by addition of Li[TFSI]. The type of electrolyte does not influence the voltammetric behavior of the amorphous TiO2 nanotube layers, whereas in case of anatase there is a definite inhibition of the Li intercalation in 1 M Li[TFSI] [BMP][TFSI], expressed by increasing the peak-to-peak voltage difference between the Li insertion and de-insertion processes. The observed phenomenon is discussed in terms of viscosity difference between both electrolytes. TiO2 nanotube structures displayed a stable galvanostatic cycling, reaching the theoretical capacity of TiO2 structure and high current efficiencies in both Li ion containing media.
