NixCo3-x,S-4@NiCo2O4 hybrid composites as supercapacitors electrode material

摘要

Three-dimensional NiXCo3-X,54@NiCo2O4 (x = 1.8) hybrid nanostructures supported on Ni foam was designed and fabricated for supercapacitor. Among different Ni-Co stoichiometries of NixCo3-XS4 electrode materials studied, NixCo3-XS4 (x =1.8) electrode materials showed the highest capacitance of 1.908 F/cm(2). Moreover, the smart combination of NiXCo3-XS4 (x =1.8) and NiCo2O4 electrode materials exhibited strong synergistic effect with significantly enhanced performances of areal capacitance up to 4.44 F/cm(2).
