Fe-based Prussian blue (FePB) has been widely studied as cathode materials of potassium ion batteries due to its three-dimensional open framework structure and large migration channels. In this study, the multi-metal (Co2+, Cu2+, Ni2+, Mn2+) doping on rate cycling properties FePB were investigated. MnCoNiFePB material shows better electrochemical performance, with initial discharge capacity 91.3 75.4 mAh g-1 (capacity retention is 56.7% after 100 cycles) at 20 mA g-1, respectively. These results inspire new ideas for development application battery electrode materials.

Potassium ion batteries, due to their similar electrochemical principles lithium-ion batteries and the abundance of metal sources, are considered one alternatives batteries. The development new cathode materials has always been a research focus in this field. Among them, Prussian blue materials, with three-dimensional open flexible framework structure, can efficiently reversibly store potassium ions. However, still face issues such as poor reversibility low capacity, which limit application scope. This study investigates preparation high-entropy analogues enhance performance. doping five different transition metals (Fe 2 ⁺, Co Cu 2+ , Ni Mn ) sharing same nitrogen coordination sites results configurational entropy greater than 1.5 R for material. HEPB-1 material (K 1.75 0.26 Fe 0.01 0.08 0.09 [Fe(CN) 6 ] 0.66 ·0.83H O) shows better performance, initial discharge capacity 86.69 74.51 mAh g −1 (capacity retention is 75.2% after 100 cycles) at 20 mA respectively. have provided insights further
