The choice of cathode and anode materials for electrochromic devices plays a key role in the performance of electrochromic smart windows.In this research,WO3/Ag and TiO2/NiO composite thin films were separately prepared by the hydrothermal method combined with electrodeposition.The electrochromic properties of the single WO3 thin film were optimized,and TiO2/NiO composite films showed better electrochromic performance than that of the single NiO film.WO3/Ag and TiO2/NiO composite films with excellent electrochromic properties were respectively chosen as the cathode and the anode to construct a WO3/Ag-TiO2/NiO electrochromic device.The response time(tc=4.08 s,tb=1.08 s),optical modulation range(35.91％),and coloration efficiency(30.37 cm2·C-1)of this electrochromic device are better than those of WO3-NiO and WO3/Ag-NiO electrochromic devices.This work provides a novel research idea for the performance enhancement of electrochromic smart windows.
