      abstract     = {Aqueous zinc-ion batteries (ZIBs) with the characteristics
                      of low production costs and good safety have been regarded
                      as ideal candidates for large-scale energy storage
                      applications. However, the nonconductive and non-redox
                      active polymer used as the binder in the traditional
                      preparation of electrodes hinders the exposure of active
                      sites and limits the diffusion of ions, compromising the
                      energy density of the electrode in ZIBs. Herein, we
                      fabricated vanadium pentoxide nanofibers/carbon nanotubes
                      (V2O5/CNTs) hybrid films as binder-free cathodes for ZIBs.
                      High ionic conductivity and electronic conductivity were
                      enabled in the V2O5/CNTs film due to the porous structure of
                      the film and the introduction of carbon nanotubes with high
                      electronic conductivity. As a result, the batteries based on
                      the V2O5/CNTs film exhibited a higher capacity of 390 mAh
                      g−1 at 1 A g−1, as compared to batteries based on V2O5
                      (263 mAh g−1). Even at 5 A g−1, the battery based on the
                      V2O5/CNTs film maintained a capacity of 250 mAh g−1 after
                      2000 cycles with a capacity retention of $94\%.$ In
                      addition, the V2O5/CNTs film electrode also showed a high
                      energy/power density (e.g., 67 kW kg−1/267 Wh kg−1). The
                      capacitance response and rapid diffusion coefficient of Zn2+
                      (~10−8 cm−2 s−1) can explain the excellent rate
                      capability of V2O5/CNTs. The vanadium pentoxide
                      nanofibers/carbon nanotubes hybrid film as binder-free
                      cathodes showed a high capability and a stable cyclability,
                      demonstrating that it is highly promising for large-scale
                      energy storage applications},
