Abstract | dc.description.abstract | We report on unique high-volume low-dimensional V2O5-based turbostratic nanostructures, prepared using sol-gel synthetic
methods from V2O5 · nH2O xerogels. Electrochemical intercalation of Li+ to form Li0.65V2O5 resulted in a maximum measured
charge capacity of 1225 mAhg−1 as the β-LixV2O5 phase. Conductivities of the order of 10−3 S cm−1 were found on compressednanotube
parallelepipedal samples, which exhibit an anisotropy factor of 70 at room temperature by preferential alignment of
the nanotubes. The improved electrochemical properties observed in novel vanadium oxide nanostructured arrays are attributed
to the increased volumetric density for ion intercalation, shorter diffusion paths to the intercalation sites, and a high degree of
crystallinity of the individual nanotubular host structures. | es_CL |
