Electrochemical performance of coin cell-type symmetric supercapacitor electrode consisting of three-dimensional molybdenum disulfide microflowers

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.
