Here, we present a neoteric approach to fabricate high performance MoS2 thin film supercapacitor electrodes by using a direct magnetron sputtering technique. The novel three-dimensional (3D) porous structure of the MoS2 film exhibits an excellent capacitance of similar to 330 F cm(-3) along with a high volumetric power and energy density of 40-80 W cm(-3) and 1.6-2.4 mW h cm(-3), respectively. Moreover, the optimized MoS2 electrode shows an outstanding cyclic stability, yielding capacitance retention over 97% after 5000 cycles of charging/discharging. The contemporary approach to MoS2 supercapacitor electrode fabrication will enable new opportunities in flexible electronic and energy devices.
