Sodium-ion batteries (SIBs) are a viable alternative to meet the requirements of future large-scale energy storage systems due to the uniform distribution and abundant sodium resources. Among the various cathode materials for SIBs, phosphate-based polyanionic compounds exhibit excellent sodium-storage properties, such as high operation voltage, remarkable structural stability, and superior safety. However, their undesirable electronic conductivities and specific capacities limit their application in large-scale energy storage systems. Herein, the development history and recent progress of phosphate-based polyanionic cathodes are first overviewed. Subsequently, the effective modification strategies of phosphate-based polyanionic cathodes are summarized toward high-performance SIBs, including surface coating, morphological control, ion doping, and electrolyte optimization. Besides, the electrochemical performance, cost, and industrialization analysis of phosphate-based polyanionic cathodes for SIBs are discussed for accelerating commercialization development. Finally, the future directions of phosphate-based polyanionic cathodes are comprehensively concluded. It is believed that this review can provide instructive insight into developing practical phosphate-based polyanionic cathodes for SIBs.

磷酸盐基聚阴离子化合物之间的距离及其在钠离子电池中的实际应用

钠离子电池（SIB）由于分布均匀且钠资源丰富，是满足未来大规模储能系统要求的可行替代方案。在各种SIB正极材料中，磷酸盐基聚阴离子化合物表现出优异的储钠性能，例如高工作电压、显着的结构稳定性和优越的安全性。然而，它们不良的电子电导率和比容量限制了它们在大规模储能系统中的应用。本文首先概述了磷酸盐基聚阴离子正极的发展历史和最新进展。随后，总结了磷酸盐基聚阴离子正极针对高性能SIB的有效改性策略，包括表面涂层、形貌控制、离子掺杂和电解质优化。此外，还讨论了用于SIB的磷酸盐基聚阴离子阴极的电化学性能、成本和工业化分析，以加速商业化发展。最后，全面总结了磷酸盐基聚阴离子正极的未来发展方向。我们相信这篇综述可以为开发用于 SIB 的实用磷酸盐基聚阴离子阴极提供指导性见解。
