nanoconfinement induction with the filling stage achieving their controllable densification through enhanced micropore confinement. This further validates and reinforces the new adsorption-intercalation-pore filling mechanism for sodium cluster densification. This work highlights nanoconfinement induction for high-rate hard carbon anodes, promoting the application of sodium-ion batteries in large-scale energy storage systems.
