The invention relates to an electrochemical device () having electrically controllable optical and/or energy transmission properties, of the type comprising two electrode coatings () and, between them, an electrochemically active layer () made of an inorganic material capable of reversibly switching between two states having different optical and/or energy transmission properties by the insertion and extraction of ions. An electrolyte () is present between the electrochemically active layer and the second electrode coating.
