The ever-increasing demand for clean energy has attracted considerable attention on the scalable and affordable potassium-ion batteries (PIBs) while one of the challenges hampering the development of rechargeable PIBs is attributed to the lack of suitable anode materials. This problem necessitates the design of cost-effective, nontoxic, and highly stable anodes with high specific capacity. In this review, we present the recent advances in rational design of carbon materials for developing such anodes for PIBs. Firstly, graphite, graphene, and disordered carbon as anodes for PIBs and their practical problems are comprehensively summarized based on sp² hybridization. Secondly, the potassium storage mechanism corresponding to the intercalation and adsorption mechanism for guiding rational design of carbon materials is discussed, followed by illustrations of how the design of heteroatom doping, porous structure, and carbon composites provides fundamental insights into high conductivity, structural integrity, and enhanced electrochemical activity. Finally, conclusions and perspectives are pointed out for developing the next-generation carbon anodes for PIBs with high energy density and excellent cycling stability.

对清洁能源的不断增长的需求已吸引了可伸缩且价格合理的钾离子电池（PIB）的大量关注，而阻碍可充电PIB的发展的挑战之一是缺乏合适的负极材料。该问题使得必须设计具有高比容量的具有成本效益，无毒且高度稳定的阳极。在这篇评论中，我们介绍了用于开发PIB阳极的碳材料合理设计的最新进展。首先，基于sp ²综述了石墨，石墨烯和无序碳作为PIBs的阳极及其实际问题。杂交。其次，讨论了与插层和吸附机制相对应的钾存储机制，以指导碳材料的合理设计，然后说明了杂原子掺杂，多孔结构和碳复合材料的设计如何提供有关高导电性，结构完整性的基本见解，和增强的电化学活性。最后，指出了结论和观点，以开发具有高能量密度和出色循环稳定性的下一代PIB碳阳极。
