Three-dimensional(3D)porous network as the current collector is essential for improving electrochemical performance of the pseudocapacitive materials because it not only increases mass loading of electroactive materials,but also ameliorates the poor electron and electrolytic ions transport.Here,we report a facile method to construct a porous Ni scaffold(PNS)on the surfaces of flexible carbon cloth(CC).In comparison with the bare(or control)CC,after MnOx nanosheets directly electrodeposited on highly conductive 3D PNS@CC,it can deliver a higher mass-specific capacitance of 1241.9 F g-1 at 1.5 A g-1,closed to the theoretical specific capacitance(1370 F g-1).
