A facile one-step hydrothermal co-deposition method for growth of ultrathin Ni(OH)(2)-MnO2 hybrid nanosheet arrays on three dimensional (3D) macroporous nickel foam is presented. Due to the highly hydrophilic and ultrathin nature of hybrid nanosheets, as well as the synergetic effects of Ni(OH)(2) and MnO2, the as-fabricated Ni(OH)(2)-MnO2 hybrid electrode exhibits an ultrahigh specific capacitance of 2628 F g(-1). Moreover, the asymmetric supercapacitor with the as-obtained Ni(OH)(2)-MnO2 hybrid film as the positive electrode and the reduced graphene oxide as the negative electrode has a high energy density (186 Wh kg(-1) at 778 W kg(-1)), based on the total mass of active materials.
