摘要
钠与锂具有相似的物理化学性质,且资源丰富,钠离子电池作为最有前途的锂离子电池替代品之一,越来越受到人们的关注。基于转化反应的铁氧化物FeOx (α/γ-Fe2O3和Fe3O4)具有成本低、比容量大等优点,是一种很有发展前途的钠离子电池负极材料。综述了FeOx材料的合成工艺、电化学性能等方面的最新研究进展。最后,对FeOx材料作为钠离子电池负极存在的问题及其未来发展方向进行了阐述。
Sodium exhibits similar physicochemical properties as lithium and abundant resources on earth. Sodium-ion batteries, one of the most promising alternatives for lithium-ion batteries, have been gaining more and more attention attracted. Iron oxides (FeOx: α/γ--Fe2O3and Fe3O4) based on con-version reaction are promising anodes for sodium-ion batteries because of its low cost and high theoretical capacity. The research progress in FeOx anodes for sodium-ion batteries was reviewed. The synthesis and electrochemical performance of FeOx were summarized. Finally, the problems and future development of FeOx as anodes for sodium-ion batteries were discussed.
