Since 2004, potassium-ion batteries (KIBs) have shown the merits of high energy densities and high power densities at low costs. To further improve their overall performance, it is essential to understand the requirements for cathodes in KIBs and screen out structures targeting at accommodating large-sized K ions.

The positive electrode materials of potassium ion batteries mainly include Prussian blue analogs, layered metal oxides, polyanionic compounds, and organic materials. The negative electrode materials are generally carbon-based materials, alloys, and metal oxides. The electrolytes basically follow the electrolyte system of lithium-ion batteries.
This type of material has been extensively studied in LIBs and SIBs and is expected to be an excellent cathode material for PIBs. At present, in potassium ion batteries, polyanion compounds that have been reported include KFePO 4, K 3 V 2 (PO) 4, KVOPO 4, KFeSO 4 F, KVPO 4 F, etc . 5.3.2.
