摘　　要：随着大规模储能领域对性价比要求的日益提升,室温钠离子电池有望成为新一代能源存储器件。在多种备选材料中,出于综合性能、成本和安全性考虑,碳基材料是最具实用潜力的钠离子电池负极材料之一。值得注意的是,体相扩散型碳和表面吸附型碳在储钠位点、电化学行为和设计思路上有很大区别。综述了两类碳材料近年来的研究进展,探讨了储钠机理、电解液匹配以及关键性能提升等问题。最后,对钠离子电池碳基负极材料研究面临的挑战及未来发展方向进行了展望。Sodium-Ion batteries(SIBs) operating at room temperature are very promising to serve as a new generation of energy storage choice with the increasing demand for low-cost high-performance devices for large-scale energy storage. Among different candidates, carbon-based material is one of the most promising choices for the practical applications of SIB anodes in virtue of their excellent electrochemical properties, low cost and high safety. Notably, bulk-diffusion type carbon and surface-adsorption type carbon show remarkable differences in sodium-storage sites, electrochemical behaviors and material design principles. This article reviews the state-of-the-art research progress of these two types of carbon materials. The mechanism for their sodium-storage, electrolyte matching and electrochemical performance improvement are also discussed. Finally, the challenges and future research related to carbon-based anode materials for SIBs is proposed.
