Abstract
En 中文
• A phosphate-mediated strategy is demonstrated to remodify the microcrystalline structure of coal-derived hard carbon. • A pseudographitic structure with extended interlayer spacing and abundant closed pores/ultramicropores is obtained. • The as-designed anode achieves an elevated capacity of 355 mAh g−1 and a superb initial Coulombic efficiency of 89.5%. • Underlying insights into the enhanced electrode kinetics and reaction mechanism are elaborately clarified.
