Abstract Regulating the microstructure of hard carbon (HC) anodes has emerged as a popular strategy to enhance application potential sodium‐ion batteries (SIBs). However, low platform capacity and inferior rate property remain significant barriers their further development. Herein, HC materials with abundant ultramicropores (0.3‐0.8 nm) are prepared employed epoxy resin zinc acetate precursors. Benefiting from hydroxyl groups, synergistic generation simple aromatic free radicals precipitated ZnO promote cross‐linking between precursor molecules during first‐step pyrolysis, alter twisting folding layers high‐temperature calcniantion, thereby precisely regulating micropore structure HC. Owing its ultramicropore boosted Na + transfer dynamics, optimal anode demonstrates superior plateau 256.2 mAh g −1 at 30 mA (408.0 reversible capacity) capability 317.0 1 A , outperforming most other resin‐derived materials. In situ Raman combined in XRD testing results demonstrate that well‐designed presents typical “adsorption‐intercalation‐pore filling” sodium storage mechanism. This work provides theoretical basis experimental guidance for high‐performance derived resin, which is essential advancements SIBs.
