Abstract

Flower-like Ag/MnO2 nanospheres with diameter of 300 nm are developed by a one-pot solution-based method. The nanoflowers are assembled by numerous ultrathin nanosheets, and Ag metal is uniformly distributed in the body of MnO2. Compared to the unmodified sample, Ag/MnO2 nanoflowers exhibit an excellent electrochemical performance with improved specific capacitance, rate capability and cycling stability, which can be attributed to good conductivity and low polarization resulting in a high utilization of active materials. This simple yet convenient synthetic route may provide a low-cost approach for the fabrication of high performance electrode materials for electrochemical capacitor application on a large scale.
