Vanadium oxide layers with homogeneous nanoporous nanotubular morphology (see picture) were successfully fabricated by direct anodization of vanadium in fluoride electrolytes such as [TiF 6 ] 2− or [BF 4 ] − . The pore size and layer thickness can easily be controlled by tailoring the electrochemical conditions. Such nanotubular or porous structures are promising for the fabrication of lithium‐ion insertion electrodes.
