Vanadium oxides (V 3 O 7 ) have been used as electrode materials for supercapacitor applications because of its multiple oxidation states. V 3 O 7 nanoparticles were coated on reduced graphene oxide (rGO) from a peroxovanadate-rGO composite by thermal microexplosive decomposition method. These V 3 O 7 decorated rGO were made composite with the flexible multi redox conducting polymer (Polyaniline). The performance of the composite materials as electrode for supercapacitors was analyzed in a 3-electrode cell, obtaining a specific capacitance of about 579 F g −1 at 0.2 A g −1 specific current. Cycling stability is one of the main barriers noticed in V 3 O 7 , which limits the practical performance of supercapacitors. This is overcome by modifying V 3 O 7 with rGO and polyaniline composites which produces good electrical contact resulting in higher capacitances and enhanced cycling stability when compared to pristine V 3 O 7 . A superior electrochemical performance and ultra-long cyclic stability of 94% over 2500 cycles was obtained through these developed electrodes. © 2019 Elsevier Ltd
