Abstract:V 2 O 5 undergoes irreversible phase transition and collapse of layered structure during the Zn 2+ insertion/extraction, which severely limits its application as a cathode for aqueous zinc-ion batteries (AZIBs). Herein, a synergistic strategy of conductive polyaniline insertion and graphene composite was proposed to boost the Zn 2+ storage performance of the V 2 O 5 cathode. A square-shaped polyaniline (PANI)-intercalated and graphene-composited vanadium oxide (GO/PANI-PVP/ V 2 O 5 ) structure was successfully… Show more
