| 钾离子电池(KIBs)凭借钾元素储量丰富、成本低廉的显著优势,已成为锂离子电池极具潜力的替代技术。石墨炔(GDY)凭借独特的结构优势,包括丰富的活性储钾位点、本征空腔结构及较大的层间距,赋予其优异的储钾性能。本综述梳理了石墨炔基碳材料在钾离子电池应用中的最新研究进展,系统总结了其结构特性、潜在储钾位点、扩散机制及电化学储钾表现。此外,还深入剖析了当前石墨炔基负极材料面临的关键挑战,包括规模化制备困难、首次库仑效率偏低以及循环稳定性不足等问题,以期推动石墨炔类碳材料在钾离子电池应用方面的蓬勃发展。 |
| 英文摘要: |
| Potassium-ion batteries (KIBs) have emerged as a highly promising alternative to lithium-ion batteries, primarily attributed to potassium"s abundant global reserves and low cost. Graphdiyne (GDY) presents distinctive structural advantages including the abundant active storage sites, inherent cavities, and expanded interlayer spacing, endowing GDY with favorable properties for potassium storage. This review summarizes the latest research advancements in GDY-based anode materials for KIBs, including the structural characteristics, underlying potassium storage sites, diffusion mechanisms and electrochemical performance. Furthermore, the current challenges faced by GDY-based anodes, including issues related to scalable synthesis, low first Coulombic efficiency, and limited cycle stability are comprehensively dissected, aiming to boost the vigorous development of GDY-based carbon materials for practical applications in KIBs. |
