ABSTRACT Hard carbons are promising anode materials for sodium‐ion batteries (SIBs), but they face challenges in balancing rate capability, specific capacity, and initial Coulombic efficiency (ICE). Direct pyrolysis of the precursor often fails to create a suitable structure storage. Molecular‐level control graphitization with open channels Na + ions is crucial high‐performance hard carbon, whereas closed pores play key role improving low‐voltage (< 0.1 V) plateau capacity carbon anodes SIBs. However, creation these presents significant challenges. This work proposes zinc gluconate‐assisted catalytic carbonization strategy regulate numerous nanopores simultaneously. As temperature increases, trace amounts remain as single atoms featuring uniform coordination structure. mitigates risk electrochemically irreversible sites enhances transport rates.
