Abstract
Abstract Hard carbons derived from coal precursors have shown bright industrial prospect as the low cost anode materials of sodium‐ion batteries. However, it is of extreme necessity yet challenge to regulate carbon microstructure toward superior sodium energy storage. In this study, we propose a powerful chemical reconfiguration tactic to steer hard carbons toward high‐capacity and fast sodium storage. The functional species on the edge/plane terminals of bituminous coal are finely reconfigured by nitri‐oxidation treatment for effectively inhibiting the reordering of carbon layers under high temperature, thereby creating rich ultramicropores/closed pores and expanded interlayer spacing. These structural merits…
