The generated closed pores enrich the sodium storage active sites of hard carbon to boost low-voltage plateau capacity. DFT calculations demonstrate that the hard carbon anode with optimal closed pore size of 0.45 nm shows peak performance.
This results in the achievement of ultra-high plateau capacity (371.7 mAh/g). Furthermore, the experi-mental results unveiled a strong positive correlation between the plateau capacity and the volume of closed pores, which facilitates so-dium ion storage.
Among them, the design of hard carbons with abundant closed pores suitable for accommodating sodium clusters is an effective strategy to improve the plateau capacity at low voltage to improve the energy density of the actual full cell.
Simultaneously, the low-voltage plateau capacity has been recognized as a critical determinant for enhancing the energy density of SIBs [12, 13]. Current research demonstrates that sodium ions confined within closed-pore architectures predominantly govern the specific capacity observed in the low-voltage plateau region [14 - 16].
