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

Multidimensional architectures of CoNiS 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 CoNiS electrode materials (NS-3) deliver a significantly enhanced specific capacitance (3784.
