V2O5 nanorods with improved cycling stability for Li intercalation
We have recently reported a solid-state, mass-quantity transformation from V2O5 powders to nanorods via a two-step approach . In this paper we present detailed investigation of the growth process using x-ray diffraction, scanning/transmission electron microscopy and electron spin resonance. The growth of nanorods at intermediate stages has been examined. Oxidation, surface energy minimization and surface diffusion play important roles in the growth mechanism.
