摘　　要：Hard carbons(HCs)are recognized as potential anode materials for sodium-ion batteries(SIBs)because of their low cost,environmental friendliness,and the abundance of their precursors.The presence of graphitic domains,numerous pores,and disordered carbon layers in HCs plays a significant role in determining their sodium storage ability,but these structural features depend on the precursor used.The influence of functional groups,including heteroatoms and oxygen-containing groups,and the microstructure of the precursor on the physical and electrochemical properties of the HC produced are evaluated,and the effects of carbonization conditions(carbonization temperature,heating rate and atmosphere)are also discussed.硬炭材料以其卓越的成本效益、环境友好性以及丰富的前驱体资源,正逐渐成为钠离子电池中极具前景的负极材料。硬炭中的石墨畴、丰富的孔隙结构以及湍流状的碳层对其储钠性能具有显著影响。然而,硬炭的微观结构十分复杂,且在很大程度上源自于前躯体材料。因此,本综述详细阐述了前躯体材料的官能团(包括含氧官能团和杂原子)和微观结构(包括形貌和孔隙结构)对硬炭物理与电化学性能的影响。此外,还讨论了炭化条件(包括炭化温度、升温速率和气氛)对最终炭样品性能的影响。本综述总结的策略和前景旨在为设计高性能钠离子电池硬炭材料提供实际指导,这些见解同样有望对其他储能系统有所助益。
