Direct Growth of NiCo2S4 Nanotube Arrays on Nickel Foam as High‐Performance Binder‐Free Electrodes for Supercapacitors
Abstract
Arrays of NiCo 2 S 4 nanotubes on nickel foam were prepared by means of a two‐step method, and were directly applied as a binder‐free supercapacitor electrode. Such a binder‐free method enables intimate contact between the current collector and the active materials, and can effectively improve ion and charge transportation. As a result, the electrochemical performances of supercapacitors can be improved. The as‐prepared NiCo 2 S 4 nanotubes/Ni foam electrode shows a high specific capacitance (738 F g−1 at 4 A g−1), excellent rate capability (78 % capacitance retention at 32 A g−1), and good cycling stability (retention capacity of 93.4 % after 4000 cycles), which suggests its promising application for electrochemical capacitors.

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.
