One-step sulfuration synthesis of hierarchical NiCo₂S₄@NiCo₂S₄ nanotube/nanosheet arrays on carbon cloth as advanced electrodes for high-performance flexible solid-state hybrid supercapacitors.

ABSTRACT: To obtain high-performance hybrid supercapacitors (HSCs), a new class of battery-type electrode materials with hierarchical core/shell structure, high conductivity and rich porosity are needed. Herein, we propose a facile one-step sulfuration approach to achieve the fabrication of hierarchical NiCo₂S₄@NiCo₂S₄ hybrid nanotube/nanosheet arrays (NTSAs) on carbon cloth, by taking hydrothermally grown Ni-Co precursor@Ni-Co precursor nanowire/nanosheet arrays (NWSAs) as the starting templates. The optimized electrode of NiCo₂S₄@NiCo₂S₄ hybrid NTSAs demonstrates an enhanced areal capacity of 245 μA h cm^-2 at 2 mA cm^-2 with outstanding rate capability (73% from 2 to 20 mA cm^-2)
