Synergistic Molecular Modulation of ππ Stacking for High‐Performance Pitch‐Derived Hard Carbon Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic molecular strategy is demonstrated to disrupt intrinsic ππ stacking in pitch, boosting 6‐fold sulfonation, yielding a hard carbon with 0.371 nm interlayer spacing and maximized closed pores, and achieving a high reversible capacity, remarkable rate capability (205.6 mAh g−1 at 2 A g−1) and cyclic stability.
