In article number 1901533, Hongbing Zhan, Zhenhai Wen and co‐workers report that bi‐heteroatom doped three‐dimensional porous carbon nanosheets show fast intercalation kinetics and robust structural stability for potassium‐ion storage. A high‐performance potassium‐ion hybrid capacitor is constructed by pairing it with an activated carbon as a cathode, providing a power device of high power/energy density and long lifespan.
