文摘

Graphene nanosheet and ternary-component nickel cobalt aluminum-layered double hydroxide composite (GNS/NiCoAl-LDH) has been successfully fabricated by a facile assembly method. The NiCoAl-LDH flakes homogeneously distribute on the surfaces of GNS, forming a three-dimensional nanosheets array structure. Electrochemical properties are characterized by cyclic voltammetry, galvanostatic charge/discharge measurements, and electrochemical impedance spectroscopy. The influence of GNS doped content on the electrochemical behavior of GNS/NiCoAl-LDH composite has been studied. The result indicate that when the GNS content is 3.0?%, the GNS/NiCoAl-LDH composite electrode exhibits a maximum specific capacitance of 1,962?F?g? at 1?A?g? and remains at 1,180?F?g? even at a high current density of 10?A?g?. After 2,000 cycles, the composite electrode keeps a remarkable specific capacitance of 1,260?F?g? at 5?A?g?. The enhanced electrochemical performances of the composite are attributed to the highly electron conductivity and large specific surface area of the graphene nanosheets. This newly designed GNS/NiCoAl-LDH composite may offer a promising electrode material for supercapacitors.
