Preparation of Highly Conductive Graphene Hydrogels for Fabricating Supercapacitors with High Rate Capability
Abstract
Graphene hydrogels prepared via hydrothermal reduction of graphene oxide dispersions (GH-Hs) were further reduced with hydrazine (Hz) or hydroiodic acid (HI) to improve their conductivities. The chemically reduced graphene hydrogels possess high conductivities of 1.3–3.2 S m –1, which are 1 order of magnitude higher than that of a GH-H (0.3 S m –1 ). The supercapacitor based on the Hz-reduced GH-H exhibited a high specific capacitance of 220 F g –1 at 1 A g –1, and this capacitance can be maintained for 74% as the discharging current density was increased up to 100 A g –1 . Furthermore, it showed high power density and long cycle life. The high-performances of this supercapacitor make it promising for high rate charge/discharge applications.

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.
