One step sputtered grown MoS₂ nanoworms binder free electrodes for high performance supercapacitor application

Two-dimensional (2D) materials have attracted significant attention for device applications due to their unique structural, electronic and catalytic properties. In this manuscript, worms like nanostructures of MoS₂ were directly deposited in the form of thin films on a copper substrate using DC magnetron sputtering technique and further it is utilized as supercapacitor electrode without additional processing. The binder free MoS₂ nanoworms symmetric supercapacitor device delivered a high capacitance (138 F/g at 1 A/g), excellent cycling ability (86% over 5000 cycles), along with high energy density (ED) and power density (PD). These observed excellent electrochemical performances of the present MoS₂ nanoworms based electrodes, suggest its tremendous potential as supercapacitor electrodes in energy storage applications.
