Abstract

The sol gel reaction of NH₄VO₃ and polymethylmethacrylate (PMMA) template followed by hydrothermal treatment formed (NH₄)_xV₂O_5-δ.nH₂O rods. TGA, SEM, XRD and FTIR characterized this compound. Heating (NH ₄)_xV₂O_5-δ.nH₂O in oxygen and nitrogen at 250°C and 300°C respectively resulted in the formation of vanadium oxides nanofibers of V₃O₇ and V ₂O₅. 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.
