Dual-function, flexible electrochromic supercapacitors (ECSs) based-on tungsten trioxide (WO3) and Li-doped ion gels containing hydroquinone (HQ) were fabricated. In this study, we investigated the electrochromic and supercapacitive performance at various HQ concentrations. At the optimal HQ concentration, the ECSs exhibited a large transmittance contrast, high coloration efficiency, high areal capacitance, and good charging/discharging cyclic and bending stability. Moreover, the practical application of the ECSs was demonstrated. The ECSs served as either an energy storage device or electrical power source. Also, they can exhibit real-time capacity in their color intensity. These results imply that the ECS developed in this study have tremendous potential for application in smart electronics and multifunctional windows for buildings and cars in future |
