A facile strategy for fabricating hierarchical nanocomposites of V 2 O 5 nanowire arrays on a three-dimensional N-doped graphene aerogel with a synergistic effect for supercapacitors

As one of the most promising candidates for supercapacitor electrodes, vanadium pentoxide (V 2 O 5 ) usually suffers from poor electronic conductivity and small ionic diffusivity.
