Implication

Review reveals key microstructural determinants of sodium storage in hard carbon anodes, highlighting sieving carbons as an optimal configuration for high-capacity batteries.

Key Points

To revisit structural models of hard carbons and clarify how their microstructures govern low-potential sodium storage mechanisms in sodium-ion batteries.
Revisited historical structural definitions, models, and mechanisms of sodium insertion in non-graphitizable amorphous carbons.
Evaluated the direct impacts of crystallites, atomic defects, and internal nanopores on low-potential charge and discharge plateaus.
Identified crystallites, defects, and nanopores as the decisive structural features controlling reversible capacity extension at low-potential plateaus.
Proposed molecular sieving carbons as an optimized anode microstructure to achieve ultrahigh reversible sodium storage capacity.
