Abstract

Abstract Boron and Nitrogen co-doped holey graphene aerogels (BN-HGA) are fabricated using ammonia borane as triple-functional precursor. The as-prepared BN-HGA possesses high specific surface area (249 m2 g−1) and rich B–N motifs with high surface polarity, which contributes to the rich and stable redox sites for the enhanced pseudo-capacitance. Moreover, the high hydrogen content in the ammonia borane cultures a reducing environment to preserve the integrity of carbon matrix, which gives rise to the high electronic conductivity. In addition, the well-developed hierarchically porous structure facilitates the ion diffusion in the electrode. Thanks to these structural merits, the BN-HGA electrode furnishes good specific capacitance of 456 F g−1 at 1 A g−1 in three-electrode systems using sulfuric acid as electrolyte. Meanwhile, the all-solid-state flexible supercapacitors based on the symmetric BN-HGA electrodes demonstrate high specific capacitance (345 mF cm −2 at 1 mA cm −2) and outstanding rate performance (80% retention at 20 mA cm −2). Furthermore, the flexible supercapacitor exhibits pleasant flexibility with marginable capacity loss as bent to arbitrary angles, which endows it a promising device for wearable energy storage.

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.
