Abstract

Iron-based phosphates for sodium-ion batteries (SIBs) have emerged as viable alternatives to lithium-ion batteries (LIBs) for grid-scale energy storage, owing to their high performance, exceptional low-temperature stability, and abundant resources. This review discusses the fundamental principles of iron-based phosphate cathode reactions from a microscopic perspective and highlights the limitations and challenges associated with NaFePO₄, Na₃Fe₂(PO₄)₃, Na₂FePO₄F (NFPF), and Na₄Fe₃(PO₄)₂P₂O₇ (NFPP) materials. To address these challenges, we systematically summarize the improvement strategies for NaFePO₄, Na₃Fe₂(PO₄)₃, NFPF, and NFPP regarding ion diffusion efficiency, electrical conductivity, and large-scale applications. Finally, through comprehensive analysis, we propose three strategic research priorities for NFPP and provide an outlook on the future development of commercially viable high-performance iron-based phosphate cathodes.

钠离子电池用铁基磷酸盐正极材料：进展、挑战和未来展望

用于钠离子电池（sib）的铁基磷酸盐由于其高性能、优异的低温稳定性和丰富的资源，已成为锂离子电池（lib）的可行替代品，用于电网规模的储能。本文从微观角度讨论了铁基磷酸盐阴极反应的基本原理，并强调了NaFePO4、Na3Fe2(PO4)3、Na2FePO4F （NFPF）和Na4Fe3(PO4)2P2O7 （NFPP）材料的局限性和挑战。为了应对这些挑战，我们系统地总结了NaFePO4、Na3Fe2(PO4)3、NFPF和NFPP在离子扩散效率、电导率和大规模应用方面的改进策略。最后，通过综合分析，我们提出了NFPP的三个战略研究重点，并对商业上可行的高性能铁基磷酸盐阴极的未来发展进行了展望。

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
