The three-dimensional MoS2 (3D-MoS2) microflowers synthesized via a hydrothermal approach exhibit excellent performance in symmetric super capacitors, with high specific capacitance and ultrahigh power density. This material shows outstanding energy storage capability and can be applied as electrodes in hybrid energy storage devices.
Three-dimensional MoS2 (3D-MoS2) microflowers consisting electrode of few-layered nanoflakes synthesized via a hydrothermal approach is a promising material for ultrahigh-performance symmetric super capacitors. A three-electrode configuration of the 3D-MoS2 microflowers exhibited a remarkable electrolytic specific capacitance of 243.31F g(-1) at 0.5 A g(-1) and 98.71% retention after 2000 charge/discharge sequences at 8 A g(-1). The fabricated coin cell-type symmetric supercapacitor devices (SSDs) showed an ultrahigh power density (P-d) of 2412.15 W Kg(-1) at an energy density (E-d) of 1.06 Wh Kg(-1), exhibiting the high energy storage capability of the 3D-MoS2 microflowers, thus enabling their application to electrodes in hybrid energy storage devices.
