摘要
无定形结构的硬炭以其不同于石墨有序结构的结构优势,以及低成本和原材料来源广,被认为是钠离子电池(SIBs)最有前途的碳基负极材料,其复杂的微观结构与钠储存有着密切的关系。在硬炭微观结构中缺陷,层间和纳米孔隙是硬炭储钠的三个关键特征结构,深入研究这些特征结构有利于实现高容量钠离子电池碳基负极的有效构造,并有利于推进钠离子电池产业化进程。最后对高性能钠离子电池负极的结构设计进行了展望。
Hard carbon with amorphous structure is considered as the most promising carbon-based anode material for sodium ion batteries(SIBs)due to its structural advantages different from the ordered structure of graphite,as well as its low cost and wide source of raw materials,and its complex microstructure is closely related to sodium storage.Among the microstructures of hard carbon defects,interlayer and nano-pores are three key characteristic structures of hard carbon for sodium storage,and an in-depth study of these characteristic structures is beneficial to realize the effective construction of carbon-based anode for high-capacity sodium ion batteries and to advance the industrialization process of sodium ion batteries.Finally,a prospect for the structural design of high performance sodium ion battery anode is provided.
