Ultra-endurance flexible all-solid-state asymmetric supercapacitors based on three-dimensionally coated MnOx nanosheets on nanoporous current collectors

Three-dimensional (3D) porous current collector is effective in enhancing the energy density per surface area of batteries and supercapacitors due to its ability for high mass loading of active materials and efficient electron and ion transport. Herein, we report a facile method to construct a nanoporous Ni architecture on the surfaces of flexible carbon cloth (Ni@CC). By electrodeposition of ultrathin MnO x nanosheets on the 3D Ni@CC nanoporous...
