Abstract The unique structural features of hard carbon (HC) make it a promising anode candidate for sodium‐ion batteries (SIB). However, traditional methods preparing HC require special equipment, long reaction times, and large energy consumption, resulting in low throughputs efficiency. In our contribution, novel synthesis method is proposed, involving the formation nanosheets (NS‐CNs) within minutes by creating an anoxic environment through flame combustion further introducing sulfur nitrogen sources to achieve heteroatom doping. effect heterogeneous element doping on microstructure quantitatively analyzed high‐resolution transmission electron microscopy image processing technology. Combined with density functional theory calculation, verified that functionalized exhibits stronger Na + adsorption ability, gain migration ability. As result, NS‐CNs as SIB anodes provide ultrahigh reversible capacity 542.7 mAh g −1 at 0.1 A , excellent rate performance 236.4 2 after 1200 cycles. Furthermore, full cell assembled can present 230 0.5 150 Finally, in/ex situ techniques confirm sodium storage properties are due construction abundant active sites based realizing . This work provides strategy develop carbons gives deep insights investigation facile preparation high‐performance alkali‐ion batteries.
