Three dimensional FeCo2O4@MnO2 core-shell nanocomposites with a unique spherical structure were prepared on nickel foam by a two-step hydrothermal + annealing method and they show the specific area capacitance 4.2 F/cm2 at a current density of 2 mA/cm2, which is nearly four times higher than that of a single FeCo2O4 electrode (1.1 F/cm2). The assembled FeCo2O4@MnO2//active carbon solid-state asymmetric supercapacitor (ASC) has a specific area capacitance of 1.81 F/cm2, an energy density of 54.3 Wh/kg and a power density of 769.6 W/kg at 10 mA/cm2. The solid-state ASC exhibited an initial capac...
