專題摘要：
In recent years, supercapacitors have been perceived as high potential energy storage because of their high power density, fast charge-discharge rate, and long cycle life. This research focuses on promoting the specific surface area and conductivity of the electrode. The process utilizes the electrospinning technique to produce carbon nanofibers (CNFs), doping silver to improve conductivity, and decorating MnO2 nanosheets on the surface by hydrothermal method to boost the capacitance. In this work, we discuss the specific capacitance of CNF/MnO2 under different mass loading. Experimental data show that the 2hr-MnO2 at 80 °C has the optimal performance. With a growth time of more than 2hr, the excess MnO2 will decline the adhesion and thus degrade the specific capacitance.
