AbstractWe present the synthesis and characterization of the hybrid PAni/V2O5 and its performance as cathode in lithium cells. The synthesis was made directly from the V2O5 gel. We observe a direct relationship between the synthesis conditions and the specific charge (Ah/Kg) obtained during the analysis of the material as cathode in lithium batteries. On the other hand, oxygen treatments were carried out to increase the oxidation state of the V2O5 in the hybrid material. Higher temperatures and period of treatment leads to the decomposition of the organic part of the hybrid PAni/V2O5. The hybrid, once treated in the optimal conditions, showed great influence over the specific charge. Values as high as 302 Ah/Kg were obtained at slow discharge rate (C/48) and 200-238 Ah/Kg at discharge rate of C/12, this values corresponds to the insertion of 2.7 and 2.08 lithium ions respectively. These values demonstrate the synergic response between PAni and the V2O5 oxide material.
