💡 Novelty & Significance:
Surface oxygen engineering of cellulose-derived hard carbon via citric acid yields 400 mAh·g⁻¹ and 91% initial Coulombic efficiency. In situ characterization reveals charge-transfer resistance cycles with sodium storage state, evidencing dynamic solvation layer formation and solvent participation. This validates the "adsorption–closed pore filling" pathway and establishes interfacial solvation structure as key to sodium storage kinetics.
