Rechargeeble sodium-ion batteries (SIBs) are promising candidates for large-scale energy storage owing to their excellent high-power performance.However,Al-based current collectorset both anodes and cathodes of SIBs,which widely influence the power properties of a variety of electrodes in SIBs,have rarely been investigated.Here,we demonstrate that vertical graphene nanosheets grown on commercial Al foil by the plasma-enhanced chemical vapor deposition (PECVD) method,form a robust connection with the carbon-based conductive network of the electrode,thereby significantly reducing the electrode-current collector interfacial resistance.For sodium vanadium phosphate (NVP) anodes with vertical graphenenanosheetmodified Al foil (G-Al) current collectors,the interfacial resistance between the electrode and current collector is reduced 20-fold compared with that in the case of Al foil.The G-Al current collector reduces the polarization and improves the rate capability compared with that of Al current collectors within both cathodes and anodes of SIBs.At a high rate of 5 C,the capacity retention of NVP cathode with G-Al current collector is 74%,which is much higher than that with Al foil (22%).We believe that the obtained results support the prospect for the widespread use of G-Al current collectors in the further improvement of high-power profiles of SIBs.
