氧化亚铁基负极材料的合成及其电化学性能研究进展

Review on the synthesis and electrochemical properties of ferrous oxide-based anode materials

铁氧化物原料来源丰富、价格低廉、对环境友好,受到研究者的广泛关注,是一类很有发展潜力的锂离子电池负极材料.与Fe_3O_4和Fe_2O_3相比,FeO重量轻,嵌/脱锂过程中,FeO在充放电过程中体积变化小,且FeO磁性更弱,具有更好的电子传导性,这对FeO获得更优的容量保持率和循环稳定性具有重要作用.本文中对FeO的结构和制备方法进行概述,并重点对FeO作为负极材料的电化学性能的研究做了综述及展望.

Iron oxides are one of the most promising anode candidates in the field of lithium-ion battery because of their high theoretical capacity,nontoxicity,low cost and abundance. Comparing with Fe_3O_4 and Fe_2O_3,FeO possess light weight,least volume changes upon lithiation,weak magnetic property,and improved electronic conductivity,which are crucial for achieving high capacity and cyclic stability. In this paper,the structure and preparation method of FeO were briefly introduced,the electrochemical performance of FeO anode material was reviewed and prospected.
