Arrays of V 2 O 5 nanowires are grown on silicon substrates by a catalytic vapor–solid mechanism (see image). The obtained nanowires are single‐crystalline and highly oriented with their lengths and substrate coverage controlled by the duration of the reaction, reaction temperature, and flow velocity. The growth of these nanowire arrays paves the way for the fabrication of novel battery architectures based on the charging/discharging of individual nanowires.
