Abstract

The coloring-bleaching process of the electrochromic device (ECD) with solid electrolyte has been studied by using microbalance and quadrupole mass spectrometer. ECD adsorbs H₂O gas and releases O₂ during coloring. The weight of ECD increases by the adsorbing H₂O gas. During bleaching ECD releases H₂ and H₂O gases and the weight of ECD returns to the weight before coloring. The weight variation of ECD is proportional to the optical density. It is suggested that the adsorbing-releasing gases change the morphology of ECD membranes and cause the crystallization of the membranes and the deterioration of the electrode of ECD.
