One step synthesis of NiCo-LDH/CoNi2S4/rGO composite on Ni foam for uneven supercapacitor: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0

Summary

The expansion of NiCo-LDH/CoNi₂S₄/rGO composite on Ni foam was achieved with a easy one-step hydrothermal methodology. The obtained binder-free electrode (NiCo-LDH/CoNi₂S₄/rGO/Ni foam) was characterised with X-ray diffraction (XRD), area emission microscopy (FE-SEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV) and galvanostastic cost/discharge (GCD). NiCo-LDH/CoNi₂S₄/rGO/Ni foam demonstrates a novel morphology with nanoparticles and nanowires mingled collectively, which endows the electrode giant floor space as verified by the Brunauer–Emmett–Teller fuel sorptometry measurement (BET). NiCo-LDH/CoNi₂S₄/rGO/Ni foam possesses wonderful cost storage capabilities resembling excessive areal capacitance, lengthy biking life and good charge efficiency. The uneven supercapacitor (ASC) with NiCo-LDH/CoNi₂S₄/rGO/Ni foam and activated carbon (AC) as constructive and detrimental electrodes was assembled, characterised and efficiently utilized in sensible functions, additional confirming the nice prospect of NiCo-LDH/CoNi₂S₄/rGO/Ni foam in vitality storage.
