摘要：
(Chemical Equation Presented) "Hedgehog" or "nest" microspheres of V2O5 are formed when nanorods of V 2O5 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. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
