Graphical abstract

We reported a new strategy for fabricating three-dimensiona electrode of Ni/Co layered double hydroxide@NiCo2S4@graphene@Ni foam for supercapacitors. The resulting 3D electrode offers a jungle-like architecture. The unique structure creates ultra fast electron transfer and electrolyte transport as well as the maximum utilization rate of the space and the surface. The electrode exhibits a prominent advantage of high specific capacitance, high-current capacitive behaviour and cycle stability. | |
