摘要	WO3 is an ideal inorganic electrochromic material. Its electrochromic mechanism is reversible redox reaction under the driving of voltage, accompanied by the insertion and extraction of counterions in the material. In this paper, we investigated the electrochromic properties of amorphous WO3 in three aqueous electrolyte solutions of Li, Zn and Al. WO3 achieves the best electrochromic performances when Al3+ was used as insertion ions, including fast response speed （2.8 s for coloring and 1.1 s for decolorization）, large optical contrast （83.4% at 700 nm）, good cycling stability （2.8% decay for 1 000 successive cycles）, high coloration efficiency （74.7 cm2·C-1）, and its comprehensive performance is at high level among the reported WO3 electrochromic devices. Mechanistic studies have revealed that the enhanced performance in Al3+ electrolytes is due to the fast ion transport kinetics. These results will provide a simple and effective guidance for the construction of high-performance electrochromic devices and the optimization of electrolytes. © 2023 Chines Academy of Sciences.
