Abstract:
A simple and versatile method was developed to prepare hollow Paramontroseite VO2 microspheres. Hollow VO2 microspheres were formed via an Ostwald ripening mechanism. The morphology, crystalline structure and electrochemical performance were systematically studied. It was found that hollow Paramontroseite VO2 microspheres can be used as stable anode and cathode materials for lithium ion batteries with acceptable rate cycling performance. In addition, the discharge capacities of hollow paramontroseite VO2 microsphere-based negative electrodes were found to reach 384.2 mAhg(-1) at a current density of 750 mAg(-1). A discharge capacity of 195.6 mAg(-1) was achieved when the microspheres were used as a cathode material for lithium-ion batteries at a current density of 20 mAg(-1). Vanadium based dual electrode materials are seldom reported in the literature.
