A new type of electrode has been prepared by the coating method from a
solution mixture of polyaniline(PANI) and V2O5. The composite electro
de exhibited high capacity density of 200 mAh cm(-3), favorable redox
activity explainable by the bi-ion-transfer mechanism, and high redox
stability against the over-discharging. This result was supported from
X ray diffraction patterns of the composite electrode.
