Abstract Establishing prediction rules for the low‐potential plateau (LPP) of hard carbon (HC) anodes is crucial constructing high‐energy‐density sodium‐ion batteries (SIBs). While current studies suggest that closed pores HC can enhance LPP performance, directly predicting from precursors have yet to be established. Here, in SIBs—the substitution index ( Δ ) precursor are introduced. Three models (disordered carbon, closed‐pore‐dominated and turbostratic carbon) constructed verify accuracy explore closed‐pore formation mechanism. In detail, as increases 0.06 0.22, capacity rises 25 278 mAh g⁻¹, revealing a strong linear correlation between capacity. situ XRD, Raman, ex SAXS, EPR further confirm sodium storage categorized into adsorption (>0.4 V), interlayer (0.4 0.15 pore‐filling (below V). This work not only elucidates mechanisms, but also provides one efficient design guideline advanced SIBs.
