      abstract     = {Nb-based NAtrium Super Ionic CONductor (NASICON) frameworks
                      (e.g., Nb2(PO4)3 and Na1.5V0.5Nb1.5(PO4)3) are emerging as
                      the attractive Na-ion anodes due to their lower
                      intercalation voltage (≈1.4–1.2 V vs Na+/Na0) and higher
                      storage capacities (≈140–160 mAh g−1). However, their
                      practical realization is limited by moderate cycle life and
                      rate performances. In this work, a carbon-coated
                      NASICON-NaV0.25Al0.25Nb1.5(PO4)3 (NaVAlNb/C) anode is
                      unveiled for fast charging Na-ion batteries. The
                      incorporation of Al3+ increases covalency of NASICON and
                      creates disordered Na-ion sublattice as observed by X-ray
                      diffraction and nuclear magnetic resonance spectroscopy
                      measurements. Besides, the carbon-coating and particle
                      downsizing produces facile electron and ion percolation
                      network. Accordingly, the NaVAlNb/C anode renders
                      extraordinary rate performances (80 mAh g−1 at 20C) with
                      longer cycling stability $(95.2\%$ retention after 5000
                      cycles at 10C). Climbing image nudged elastic band
                      calculations reveal reduced Na-ion migration barrier (202
                      meV) for NaVAlNb/C. Most importantly, a full Na-ion cell
                      based on Na4V2(PO4)3 cathode and NaVAlNb/C anode is
                      demonstrated with a high-power density (6493 W kg−1) and
                      long-cycle life (3000 cycles at 20C), which are far
                      excellent compared to the state-of-the-art NASICON-based
                      cells. This work demonstrates the significance of carbon
                      coating and chemical tuning to tailor high-rate NASICON
                      anodes, which can produce fast-charging Na-ion batteries.},
