摘　　要：锂离子电池的性能在很大程度上由其电极材料决定.目前,商用的锂离子电池负极材料主要为石墨,其性能并不能满足下一代大容量/高功率锂电池的需求.尽管科研工作者在新型锂离子电池负极材料方面做了大量的研究,但距离其大规模应用仍然有诸多问题需要解决,其中最重要的问题之一为实现其高产率/低成本的规模化制备.本文重点介绍了本课题组在一维纳米结构负极材料规模化制备方面取得的进展,包括一维多孔三氧化二铁/四氧化三钴、一维多孔草酸盐和一维多孔铁酸锌.The electrochemical performances of lithium-ion batteries are highly dependent on their electrode materials. The currently used graphite anode is limited by the low theoretical capacity and can＇t meet the demand of the next generation lithium-ion batteries with higher energy and power density. Although great progress has been achieved with the development of new anode materials instead of graphite, it is still far from realizing commerce success. One of the most important points is the large-scale production of the new anode materials with high-yield and low-cost. This short article reviews the recent progress in large scale synthesis of one dimensional nanostructured anode materials in our research group, including one dimensional porous α-Fe2O3, Co3O4, anhydrous oxalates and zinc ferrite.
