In order to improve the properties of vanadium oxide as cathodes, Fe(x)V2O5(x=0.002, 0.02, 0.05) xerogel was synthesized by adding small amount of Fe to V2O5 sol that was derived via a sol-gel process. Coating processes, such as a spin coating and a dip coating, and a heat treatment technique were employed to investigate the effectiveness of each technique by testing the cell performance using the Fe(x)V2O5 as the cathode. The results showed that the spin coated Fe(x)V2O5 xerogel had a higher capacity and a better reversibility than both the dip coated Fe(x)V2O5 xerogel and the heat treated Fe(x)V2O5 at 400 ℃. The capacity of sp-Fe0.05V2O5 xerogel was greatly enganced by more than 370 mAh/g. In general, as the thickness of the Fe(x)V2O5 xerogel was decreased and the added amount of doped Fe in the V2O5 increased, the electrochemical properties such as the reversibility and cell capacity were enhanced

바나듐 산화물계 양극소재의 물성을 향상시키고자 졸겔법을 이용하여 제조한 V2O5 졸에 미량의 Fe 원소를 도핑시켜 Fe(x)V2O5 xerogel (x=0.002, 0.02, 0.05)을 제조한 후, 집전체에 전극을 처리하는 방법을 변화시키면서 리튬전지 양극소재로서의 전기화학적 특성을 연구하였다. Spin coating법을 이용하여 집전체에 도포한 전극(sp-Fe(x)V2O5)이 dip coating법이나, 400℃에서 열처리한 Fe(x)V2O5보다 전지용량 및 가역성에서 우수하였으며, 실험적으로 얻은 sp-Fe0.05V2O5의최대용량은 370 mAh/g 이상이었다. V2O5 구조내에 도핑된 Fe의 함량이 증가할수록, 막의 두께가 얇을수록 양극용량이 증가하였으며, 충방전 특성이 우수하였다.
