Synergistic CO2 Etching and Carbonization for High Sodium Storage Hard Carbon Materials

Caption

Synergistic CO2 etching and carbonization process: chitosan-derived precursor undergoes CO2 activation at 800℃ to form open-pore CH-800, followed by temperature-controlled (x℃) Ar-atmosphere carbonization to yield closed-pore-rich CH-800-x hard carbon for high-performance sodium storage.
