Abstract This research focuses on the field of supercapacitor electrode materials. Using Rhus typhina leaves as starting material, it innovatively applies a mixed activator composed K 2 CO 3 and ZnCl successfully prepares O/N self‐doped leaf‐derived porous carbon materials (TLMPC‐x) through precisely controlled two‐step carbonization‐activation method. The aim is to develop new type material that combines excellent performance, environmental friendliness, advantage low cost, deeply explore mechanism effect ratio specific surface area electrochemical performance Among them, TLMPC‐1.0 remarkably exhibits high 2827.9 m g −1 . Its abundant multi‐level pore structure complements well with diverse heteroatom doping. During test in KOH electrolyte system, capacitance this excellently reaches 335.3 F , retention rate stably maintained at 69%. When power density 250 W kg an energy 9.45 Wh can be achieved. Moreover, after 20 000 charge–discharge cycles, its still 96.4%, demonstrating extremely ultra‐stable cycle stability.
