Abstract Biomass‐derived hard carbon (HC), a promising anode material for sodium‐ion batteries with low cost and good cycling ability, has high surface activity that easily reacts the electrolyte, causing initial coulombic efficiency (ICE) poor stability. This article proposes facile synthesis of pine wood‐derived HC N‐doped soft (SC) coating strategy to improve electrochemical performance, especially ICE. The optimized exhibits higher reversible capacity 314.0 mAh g −1 at 30 mA·g greatly enhanced ICE 85.2%, rate performance 260.0 5.0 C. Combined in situ/ex situ characterizations, SC increased closed pores is beneficial improving sodium storage explored as adsorption‐filling behavior, favoring high‐rate performance. Density functional theory (DFT) calculations further revealed nitrogen doping adsorption kinetics provides more sites Na + storage, increasing capacity. work in‐depth insights into modification carbon, offers new opportunities design efficient anodes.
