Synthesis of Vanadium Pentoxide Hollow Microspheres and Application as Cathode in Rechargeable Mg Batteries
Abstract:
With carbon spheres(CS) as the template,vanadium pentoxide(V2O5) hollow microspheres were synthesized by the solvothermal reaction of vanadium oxytriisopropoxide(VOT). The structure,morphology and component of V2O5 hollow microspheres were characterized by scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The results reveal that V2O5 hollow microspheres are perfectly generated with the diameter of ~1.5 μm and the wall thickness of ~100 nm. As a cathode material for rechargeable Mg batteries,the initial discharge capacity is up to 140 mA·h/g at the rate of 0.2 C and maintains 110 mA·h/g after 20 cycles.
