摘要
Ag2O-loaded NiO ball-flowers were synthesized via a simple one-step hydrothermal method. The ball flower architecture is constructed by porous nanosheets modified by Ag2O. During the charge-discharge processes Ag2O can convert to metallic Ag to enhance the conductivity of electrode materials. The unique hierarchical ball-flower architectures can provide more active sites and diffusion paths for ions, increasing the utilization rate of electrode materials. Electrochemical measurements reveal that electrode materials based on Ag2O/NiO nanocomposites exhibited high specific capacitance value (556 F g(-1)) at a current density (1 A g(-1)), as well as an excellent capacitance retention of 103% after 1000 cycles.
