Carbon has become the major material of supercapacitor in recent years. Among the preparing methods, ultrasonic spray technology provides a simple and large area process. Besides, the spray nozzle equipped with an ultrasonic oscillator can further make the paste finer and uniformly distributed on the substrate. In this study, the high specific surface area activated carbon was added into binder with various compositions for the ultrasonic spray process. The sprayed active carbon-based electrode on the metal substrate was used to study their capacity characteristic. The field emission scanning electron microscope and α-step were used to examine the thickness and surface morphology. The experiment results show that the paste of 11 wt% activated carbon and 0.5 wt% silver nanowires by ultrasonic spray process with the thickness of 23.6 μm has the optimum conductivity and specific capacitance of 1990 S/m and 350.4 F/g, respectively.
