摘要：
The sol gel reaction of NH4VO3 and polymethylmethacrylate (PMMA) template followed by hydrothermal treatment formed (NH4)(x)V2O5-delta.nH(2)O rods. TGA, SEM, XRD and FTIR characterized this Compound. Heating (NH4)(x)V2O5-delta.nH(2)O in oxygen and nitrogen at 250degreesC and 300degreesC respectively resulted in the formation of vanadium oxides nanofibers Of V3O7 and V2O5. Performance of these compounds as cathode in rechargeable lithium battery was investigated in a LiPF6/mixed carbonate electrolyte. The materials show good cycling with capacity greater than 130mAh/g, which translates to the insertion of 0.5 moles of Li+ per vanadium of the active material.
