| Abstract: | A simple WO 3 dry lithiation is carried out by electron beam evaporation of metal lithium.The components and electrochromic properties of the lithiated films with different lithiation degrees are characterized by X ray photoelectron spectroscopy and electrochemical method.Experiment results indicate that if Li/W ratio is less than 0.25,tungsten bronze Li xWO 3 is formed and the lithiated films have good reversibility and coloration efficiency.Finally,a lithium based all solid state electrochromic device with proper lithiation degree is fabricated using this dry method. |
| Keywords: | dry lithiation tungsten trioxide electrochromic |
