TÓM TẮT
Bio-inspired and cost-effective development of highly porous foam-like carbon structure originating from waste fg-fruit raw materials using chemical activation is described. The as-synthesized porous sample exhibits a specifc surface area higher than 2000 m2 g-1 and relatively high porosity with ultimately interconnected micro-, meso-, and macropores. Such sample displays superior specifc 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.
