This invention teaches electrochromic lead 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 lead oxide are arranged between an anode and a cathode to form an electrochromic device. Preferably, the lead oxide is in a layer next to the cathode. With the lead oxide layer next to the cathode, the device is a cathodic electrochromic device which can generate a dark grey color.
