Abstract
Abstract Electrochromic mirrors hermetically sealed from the ambient environment and comprising at least one electrode, at least one electrochromic layer, a reflector, at least one ion-conducting layer, and at least one ion-supplying layer which simultaneously is an ion-storing layer and is not identical with the reflector, wherein the ion-conducting layer consists essentially of an ion-conducting inorganic solid.
