MoS2 is considered as an efficient electrode material for energy storage application due to its lamellar structure in analogs with graphene. In this report, metallic 1T-MoS2 is allowed to grow on reduced graphene oxide (rGO) sheets through hydrothermal treatment. The crystallinity, surface morphology and elemental composition of the as synthesized material have been carefully analyzed. As a result of fascinating surface morphology, the as-prepared rGO/MoS2 composites exhibit excellent electrochemical properties including high specific capacitance, long cycle life, high energy and power densities. The maximum specific capacitance of 713.4 F/g is obtained at 1 A/g current density for 10 weight % of rGO loaded MoS2 sample in three electrode cell system. The symmetric device exhibits an outstanding specific capacitance of 170 F/g at 1 A/g current density and a 51.08% retention is obtained even at 10 A/g current density. Moreover, the symmetric device exhibits an appreciable energy density of 51.2 Wh/kg at a power density of 750 W/kg, and high capacitive retention of 88% is observed even after 10,000 charge/discharge cycles. This outstanding performance of rGO loaded 1T-MoS2 electrode promises its applicability in energy storage devices, especially in supercapacitors.
