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.
