Self‐Assembled Vanadium Pentoxide (V2O5) Hollow Microspheres from Nanorods and Their Application in Lithium‐Ion Batteries

Graphical Abstract “Hedgehog” or “nest” microspheres of V2O5 are formed when nanorods of V2O5 are synthesized in a mediated polyol process. When the concentration of the starting material is low, a nest shape is preferred, whereas a high concentration of [V(acac)3] affords hedgehog-shaped microspheres (see picture). The V2O5 microspheres exhibit remarkable electrochemical properties when used as the cathode material in a lithium-ion battery.
