💡 Novelty & Significance:
This work pioneers VN nanoparticles in lotus-root-like porous carbon nanofibers to synergistically coordinate Na nucleation thermodynamics and deposition kinetics. Electronic-structure engineering creates sodiophilic N/V sites lowering nucleation barriers, while hierarchical porosity homogenizes ion/electric fields. The result—dendrite-free cycling over 1000 h with 99.86% CE—establishes electronic-structure-induced sodiophilicity as a decisive design descriptor for stable alkali-metal anodes.
