Lithium ion batteries have been widely used in portable electronic devices and electric vehicles. However, with the exploitation of lithium resources in the earth's crust, the cost of lithium ion batteries is gradually increasing. In contrast, the higher potassium content in the earth's crust promises a low cost of potassium ion batteries, and the potassium ions have similar chemical properties with the lithium ions. Meanwhile, the low redox potential of K/K+ (-2.93V vs. SHE) promises a high working voltage of potassium ion batteries. Thus, potassium ion batteries have attracted lots of attention as capable battery technology. However, the potassium ion with a large radius leads to unsatisfied ion intercalation and extraction behavior during charging and discharging processes, which results in poor cycling performance, unsatisfied rate ability, and low capacity. It is still a challenge to explore capable electrode materials for potassium ion batteries to achieve a high energy density and power density.
