The host has a large surface area and excellent mechanical strength, which helps to lower the local current density and buffer the volume expansion. By providing abundant nucleation sites, it guides uniform potassium deposition and inhibits dendrite growth. The anode can cycle for 2000 hours under the given current condition, surpassing other reported potassium metal anodes.
