Biomass derived interconnected hierarchical micro-meso-macro- porous carbon with ultrahigh capacitance for supercapacitors
Abstract
Abstract The cost-effective biomass derived carbon with high electrochemical performance is highly desirable for the sustainable development of advanced energy storage devices. However, most of the reported biomass carbon materials suffer from the low capacitance in the range of 0–400 F/g as the electrode for supercapacitor. Herein, we reported, for the first time, the fabrication of tri-modal porous carbon with a record high capacitance of 550 F/g at 0.2 A/g for biochar materials from shaddock endotheliums by a feasible method combined with metal ion impregnation and molten KOH activation. The as-prepared carbon also showed an outstanding energy density of 46.88 Wh/kg with a power density of 300 W/kg in 1 M BMIMBF4/AN with high capacitance retention over 93.7% after 10000 cycles, which is rarely achieved by the peer reported biochars. Its high electrochemical performance is attributed to combined contributions from high surface area (1265 m2/g), hierarchical porous structure, high graphitization level and abundant heteroatoms (about 10 atom%) co-doping. The work provides an outstanding renewable candidate and a feasible route design strategy for fabrication of high performance electrode materials.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
