Chemically preintercalated bilayered vanadium oxide (BVO) electrodes derived from V2CTx MXene exhibit superior Na-ion storage performance compared to compositionally similar BVO counterparts synthesized from α-V2O5 powder. Here, we report for the first time the precursor-dependent structural differences in Na-preintercalated BVO electrodes (δ-NaxV2O5·nH2O) synthesized from α-V2O5 powder (AD-NVO) and V2CTx MXene nanoflakes (MD-NVO) and show how these differences govern their electrochemical behav
