It is essential to replace lithium-ion batteries (LIBs) from the perspective of the Earth's resources and the sustainable development of mankind. Sodium-ion batteries (SIBs) are important candidates due to their low price and abundant storage capacity. Hard carbon (HC) and graphite have important applications in anode materials of SIBs. In this review, the research progress in electrolyte and interface between HC and graphite anode for SIBs is summarized. The properties and performance of three types of widely used electrolytes (carbonate ester, ether, and ionic liquid) with additives, as well as the formation of solid electrolyte interface (SEI), which are crucial to the reversible capacity and rate capability of HC anodes, are also discussed. In this review, the co-intercalation performance and mechanism of solvation Na⁺ into graphite are summarized. Besides, the faced challenges and existing problems in this field are also succinctly highlighted.

钠离子电池硬碳石墨负极电解质及界面研究进展

从地球资源和人类可持续发展的角度来看，更换锂离子电池（LIBs）至关重要。钠离子电池 (SIB) 因其价格低廉且存储容量大而成为重要的候选者。硬碳（HC）和石墨在 SIBs 的负极材料中有重要的应用。本文综述了SIBs电解质及HC与石墨负极界面的研究进展。三种广泛使用的电解质（碳酸酯、醚和离子液体）与添加剂的性质和性能，以及固体电解质界面 (SEI) 的形成，这对 HC 负极的可逆容量和倍率性能至关重要, 也进行了讨论。^{在这篇综述中，溶剂化 Na +}的共插层性能和机理对石墨进行了总结。此外，还简洁地突出了该领域面临的挑战和存在的问题。
