摘要
随着能源与环境问题的日益加剧,发展绿色能源存储与转化技术变得越来越重要.作为一种环境友好型储能器件,钠离子电池的快速发展激发了对高性能正极材料的需求.在各类正极材料中,无定形磷酸铁(FePO_(4))因其较高的理论比容量和优异的电化学可逆性而受到了广泛关注.基于此,本文综合评述了无定形FePO_(4)作为钠离子电池正极材料的研究进展.首先,介绍了无定形FePO_(4)的基本特征及其应用;然后,系统总结了其常见的合成方法,如模板法、水热法等;介绍了增强无定形FePO_(4)储钠性能的策略,强调了形貌结构和性能之间的紧密联系;最后,对该领域进行了总结与展望.
With the increasingly serious energy and environmental problems,the development of green energy storage and conversion technologies becomes more and more crucial.As an environmentally friendly energy storage device,the rapid development of the sodium-ion batteries(SIBs)has stimulated the demand for high-performance cathode materials.Among various kinds of cathode materials,amorphous iron phosphate(FePO_(4))has attracted enormous attention as a promising cathode material for sodium-ion batteries because of its high theoretical specific capacity and superior electrochemical reversibility.Herein,this review is focused on recent advances in amorphous FePO_(4)for sodium-ion battery cathodes.First,the common characteristics and applications of amorphous FePO_(4)are introduced.Next,the synthesis methods are summarized,including template synthesis,hydrothermal synthesis and some other methods.Subsequently,the research progress of strategies to improve sodium-ion storage properties is introduced in detail,with an emphasis on the relationship between structure and performance.Finally,the conclu⁃sion and prospects in this field are discussed.
