Bio‐inspired and cost‐effective development of highly porous foam‐like carbon structure originating from waste fig‐fruit raw materials using chemical activation is described. The as‐synthesized porous sample exhibits a specific surface area higher than 2000 m 2 g −1 and relatively high porosity with ultimately interconnected micro‐, meso‐, and macropores. Such sample displays superior specific capacitance in aqueous electrolyte of 340 and 217 F g −1 at current density of 0.5 A and 20 A g −1 , respectively, along with a high energy/power density performance compared to that developed in the literature and the commercial supercapacitors up to now. In addition, the sample also exhibits an extremely high stability as a function of cycling tests with more 99% capacitance retention after 10 000 cycles.
