Abstract Recently, to ameliorate the forthcoming energy crisis, sustainable energy conversion and storage devices have been extensively investigated. Potassium-ion batteries (KIBs) have aroused widespread attention in these very active research applications due to their earth abundance and similar low redox potential compared to Li-ion batteries (LIBs). It is critical to develop electrode materials with large ion diffusion channels and robust structures for long cycling performance in KIBs. Metal coordination materials, including metal–organic frameworks, Prussian blue, and Prussian blue analogue, as well as their composites and derivatives, are known as promising materials for high-performance KIBs due to their open frameworks, large interstitial voids, functionality and tailorability. In this review, we give an overview of the recent advances on the application of metal coordination materials in KIBs. In addition, the methods to enhance their K-ion storage properties are summarized and discussed, such as morphology engineering, doping, as well as compositing with other materials. Ultimately, some prospects for future research of metal coordination materials for KIBs are also proposed. Graphic abstract

基于金属配位材料的钾离子电池电极材料研究进展与展望

摘要 近年来，为了缓解即将到来的能源危机，可持续能源转换和存储设备得到了广泛的研究。与锂离子电池 (LIB) 相比，钾离子电池 (KIB) 具有丰富的地球资源和类似的低氧化还原电位，因此在这些非常活跃的研究应用中引起了广泛关注。开发具有大离子扩散通道和坚固结构的电极材料对于 KIB 中的长循环性能至关重要。金属配位材料，包括金属有机骨架、普鲁士蓝和普​​鲁士蓝类似物，以及它们的复合材料和衍生物，由于它们的开放框架、大间隙空隙、功能性和可裁剪性，被认为是高性能 KIB 的有前途的材料。在这次审查中，我们概述了金属配位材料在 KIB 中应用的最新进展。此外，总结和讨论了增强其钾离子存储性能的方法，例如形态工程、掺杂以及与其他材料的复合。最后，还对未来KIBs金属配位材料的研究提出了一些展望。图形摘要
