This paper reports a study on template-growth and electrochemical properties of single-crystal vanadium pentoxide (V{sub 2}O{sub 5}) nanorod arrays from V{sub 2}O{sub 5} aqueous solution using electrochemical deposition. Uniformly sized vanadium oxide nanorods with a length of about 10 {micro}m with diameters ranging from 100 to 200 nm were grown over a large area with near unidirectional alignment. These nanorods have single-crystalline structure with a growth direction of [010]. Electrochemical property analysis indicates that nanorod array electrodes have significantly higher current density and energy storage density than sol-gel-derived V{sub 2}O{sub 5} films.
