Potassium-ion batteries have recently attracted considerable attention as cost-effective alternatives to lithium-ion batteries for large-scale energy storage. However, a major obstacle to the practical application of this emerging technology is the lack of suitable cathode materials that are capable of delivering high gravimetric/volumetric energy, stable cycle life, and high rate capability. In this review article, we review the recent progress in cathodes development for potassium-ion batteries. These materials are categorized into four types: layered oxides, Prussian blue analogs, poly-anion, and organic compounds. Based on our critical review of the reported literature, we identify poly-anion compounds as a class of promising candidates among all types and provide suggestions for future optimization.
