摘要

由于资源和成本优势，以及工作原理与锂离子电池的相似性，钾离子电池在未来的大规模储能应用中有着光明的发展前景。然而相比于锂、钠离子，钾离子半径较大，这不仅影响了其在电极中的输运，而且容易对电极材料的结构造成一些不可逆的破坏，进而导致较差的电化学性能。对于钾离子电池，负极可采用与锂离子电池相同的石墨负极，而正极材料是目前的研发高性能钾离子电池的关键。因此，本文在总结了最常见的四类钾离子电池正极材料的相关进展，并分别探讨了各自的优势、问题及相应的改性方法的基础上，展望了钾离子电池正极材料未来的发展。

Abstract

Due to resource and cost advantages

as well as the similarity of working principles with lithium-ion batteries

potassium-ion batteries (PIBs) have a bright future in large-scale energy storage applications. However

the ion size of potassium is larger than that of lithium and sodium ions

which not only affects the transport in the electrode

but also tends to cause irreversible damage to electrode structure

resulting poor electrochemical performance. For PIBs

the graphite that already applied in lithium-ion batteries can be used as anode

thus the cathode materials are the key to develop the high-performance potassium ion batteries. This review summarized the progress of various types of cathode materials for PIBs

and discussed their advantages

problems and corresponding modification methods. Finally

the main challenges and perspectives are also discussed to provide the future direction of cathode materials for PIBs.
