“ Hedgehog” or “nest” microspheres of V 2 O 5 are formed when nanorods of V 2 O 5 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 V 2 O 5 microspheres exhibit remarkable electrochemical properties when used as the cathode material in a lithium‐ion battery.
