Abstract
We have fabricated a thin-film electrochromic device consisting of WO3 and Li-doped MgF2 films. Although the device exhibited excellent coloration and bleaching response (coloration period: ∼100 ms, bleaching period: ∼200 ms), the following changes in the device characteristics were observed upon retreated operation: 1) bleaching was impaired, 2) spontaneous coloration increased while spontaneous bleaching decreased and 3) the threshold voltage for coloration decreased. We have found that these changes can be attributed to the change in the free energy or the Li+ ion.Keywords
