Three-Dimentional Porous Nano-Ni/Co(OH)2 Nanoflake Composite Film: A Pseudocapacitive Material with Superior Performance
Abstract
We report a novel three-dimentional (3D) porous nano-Ni/Co(OH) 2 nanoflake composite film electrode for potential supercapacitor applications with both high power and energy capabilities. The 3D porous nano-Ni film with highly porous nanoramified walls functions as a scaffold to anchor Co(OH) 2 nanoflakes to produce a 3D nanoporous metal/hydroxide nanoflake composite electrode. Co(OH) 2 nanoflakes with thicknesses of 20 nm are directly electrodeposited on highly conductive 3D porous nano-Ni film prepared via a hydrogen bubble template. Impressively, the Co(OH) 2 nanoflake in the composite film exhibits a high specific capacitance of 1920 F g –1 at 40 A g –1, with a corresponding energy density as high as 80 W h kg –1 at a power density of 11 kW kg –1 . Moreover, the designed composite film exhibits excellent cycling stability, making it one of the best electrode materials for high-performance supercapacitors. This work demonstrates that the 3D porous nanometal/hydroxide nanoflake composite approach is an effective strategy toward supercapacitors with high energy and power densities.

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.
