摘要
This invention teaches electrochromic bismuth oxide as a new electrochromic material. An electrochromic device is constructed from this material by forming a cathodic electrochromic device. A fast ion conductor is also provided which is capable of generating ions when an electric field is applied thereto. The fast ion conductor also permits ion movement therethrough while prohibiting electron movement therethrough. The fast ion conductor and the electrochromic bismuth oxide are arranged between an anode and a cathode to form an electrochromic device. Preferably, the bismuth oxide is in the form of a layer and that layer is positioned next to the cathode to form a cathodic electrochromic device which can generate a dark gray color.
