Multidimensional structure of CoNi₂S₄ materials: structural regulation promoted electrochemical performance in a supercapacitor.

ABSTRACT: Multidimensional architectures of CoNi₂S₄ electrode materials are rationally designed by engineering the surface structure toward that of high-performance supercapacitors. The fabrication of a special morphology is highly dependent on the synergistic effect between the guidance of Co-Ni precursor arrays and a subsequent sulfidation process. The unparalleled CoNi₂S₄ electrode materials (NS-3) deliver a significantly enhanced specific capacitance (3784.6 F g^-1 at 3 A g^-1), accompanied by an extraordinary rate capability (2932.3 F g^-1 at 20 A g^-1) and excellent cycling life. The outstanding supercapacitor performance stated above stems from the advantages of a multidimensional structure generated by crossl
