Hybrid electrodes based on polyaniline/V2O5 for the development of plasticlithium batteries

We present the synthesis and characterization of the hybrid PAni/V2O5 and i ts performance as cathode in reversible lithium cells. The synthesis was ma de directly from the V2O5 gel. We observe a direct relationship between the synthesis conditions and the specific charge (Ah/Kg) obtained during the a nalysis 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 le ads to the decomposition of the organic part of the hybrid PAni/V2O5. The s yntesis conditions of the hybrid, showed great influence over the specific charge. Values as high as 302 Ah/Kg were observed at slow discharge rate (C /48) and 200-238 Ah/Kg at discharge rate of C/12, this values correspond to the insertion of 2.7 and 2.08 lithium ions respectively. These values demo nstrate the synergic response between PAni and the V2O5 oxide material.
