• As a new generation of electrode material, flexible electrode material can effectively broaden the application area and scope of energy storage devices. In this paper, a new vanadium pentoxide carbon fiber cloth (V2O5-CFC) is successful synthesized by means of electrospinning and high-temperature calcination. As a cathode material for aqueous zinc-ion batteries, V2O5-CFC possesses significantly increased specific capacity (132 mA h g−1 at 1 A g−1) and good cycling ability (154 mA h g−1 at 0.5 A g−1 after 1000 cycles). The volume effect in the charge/discharge process can be alleviated by using a composite fiber structure to avoid agglomeration of V2O5 nanosheets. Most important, V2O5-CFC displays the flexible property and demonstrates its potential applications as a high-energy density and flexible energy storage device with good reversibility. Therefore, the design and synthesis strategy of flexible nanofibers film is prospective for applications in next-generation flexible aqueous zinc-ion batteries. •V2O5 carbon fiber cloth exhibits excellent flexibility.•The cathode for ZIBs displayed large specific capacity, good cycling ability.•3D network structure accelerates intercalation kinetics of Zn2+ transport.
