A novel anode material with a delicate composite structure, which is assembled by growing 3D MoSe2 nanoflowers onto the hierarchically anisotropic carbon architecture, is designed for the first time. The structural superiority and synergistic effects from EDLC and pseudocapacitance endow the free-standing anode with an ultra-high areal capacitance of 1043 mF cm-2 at 1 mA cm-2 and high cycling stability. Moreover, an asymmetric supercapacitor device consisting of this anode and a common MnO2-based cathode yields a quite large energy density of 147 muW h cm-2 at the power density of 2 mW cm-2, w...
