Enhancing Plateau Capacity of Binder‐Free and Self‐Supported Napkin‐Based Hard Carbon Anodes for Sodium‐Ion Batteries Via a Pre‐Oxidation Modulation Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
Precise regulation of preoxidation time and carbonization temperature in biomass napkin‐derived hard carbon generates abundant closed pores and ultramicropores, significantly enhancing the capacity in the low‐potential plateau region (the high plateau capacity of 266 mAh g−1) and thereby achieving highly reversible sodium‐ion storage (395 mAh g−1 at 30
