The carbonaceous anodes in sodium ion batteries suffer from low initial Coulombic efficiency (ICE) and poor cyclability due to rampant solid electrolyte interface (SEI) growth. concept of the weakly solvating (WSE) has been popularized for SEI regulation on anode by adjusting cation solvation structure. Nevertheless, effects sheath electrode/electrolyte are ignored most WSE applications. In this work, we extend bulk electrolyte/carbon interface. By recycling asphalt wastes into sp2 C enriched few-layer carbon hard carbon, a is fabricated with lower adsorption energy solvent molecules than pristine (−0.89 vs −1.08 eV Na/diglyme). Accordingly, more anionic groups attracted solvent-weakened during sodiation (2.30 1.96 coordination number PF6–). anion-mediated contact pairs facilitate thin, inorganic-rich layer homogeneous distribution, which confers high ICE 97.9% capacity 335.6 mA h g–1 at 1 (89.5% retention, 1000 cycles). full battery also manifests an density 209 W kg–1.
