💡 Novelty & Significance:
Pressure-driven thermomechanical sintering reconfigures semi-coke’s aromatic topology, suppressing graphitization while creating twisted pseudo-graphitic domains and closed nanopores. This yields fast-charging hard carbon (80% SOC in 14.4 min) with 90.1% plateau-capacity retention via abundant Na+ sites, rapid diffusion, and stable NaF-rich SEI. It establishes a scalable route to upgrade cheap semi-coke into high-performance anodes.
