摘　　要：高性能钾离子电池的发展及应用是中国战略性新兴产业的重大需求,也是储能二次电池发展的新体系与新方向。然而,目前钾离子电池仍面临扩散动力学慢及输运机制不明、容量衰减快和本征衰减机制难以揭示等难题。本文系统总结了国家自然科学基金重点项目“分级介孔纳米线钾离子电池正极材料的表界面调控及原位作用机制”的最新研究成果,系统阐述了钾离子电池研究中的关键科学问题和技术瓶颈,并提出了解决以上问题和瓶颈的高效策略。The development and application of high performance potassium ion batteries(PIBs) is a major demand for China's strategic emerging industries,and it is also a new system and direction for the development of energy storage secondary batteries.However,the current research on PIBs is still in its initial stage,and still faces the challenges of slow diffusion kinetics,unclear transport mechanism,rapid capacity decay and difficulty in revealing the intrinsic decay mechanism.This paper summarizes the latest research results of the National Natural Science Foundation of China(NSFC) project "Surface/Interface Tuning and In Situ Interaction Mechanism of Hierarchical Mesoporous Nanowire Cathodes for Potassium Ion Battery",systematically describes the key scientific problems and technical bottlenecks in PIB research,and points out the efficient strategies to solve these problems and bottlenecks.
