Results demonstrate that the thermal runaway propagation in a module containing the overcharged cell follows a sequential triggering mode, while thermal runaway in the downstream module exhibits a simultaneous triggering mode with greater severity. Furthermore, increasing the module spacing or enhancing the heat dissipation capacity can effectively reduce the heat accumulation and prevent the trigger of thermal runaway.

Here, we propose a scalable dual-regulation strategy that simultaneously tunes pore mouth size and defect chemistry to enhance sodium storage performance. Using phenol-formaldehyde resin as the carbon precursor and phosphorus pentoxide (P<sub>2</sub>O<sub>5</sub>) as a bifunctional sacrificial template and dopant source, we synthesize phosphorus-functionalized hard carbon (PF-PHC) featuring a high density of closed pores with well-confined sub-nanometer pore entrances. The in-situ sublimation of P<sub>2</sub>O<sub>5</sub> during pyrolysis promotes the formation of closed-pore architectures, while residual phosphorus atoms effectively passivate vacancy-type defects, thereby reducing irreversible Na<sup>+</sup> adsorption and mitigating excessive solid electrolyte interphase (SEI) formation. As a result, PF-PHC achieves an ICE of 89.3% and a plateau capacity of 289 mAh g<sup>−1</sup>. In-situ characterizations reveal that regulating pore mouth dimensions decouples Na<sup>+</sup> and solvent access, enabling highly selective ion transport and stable interfacial chemistry.
