DETAILED DESCRIPTION Accordingly, one object of the invention is to provide a means for increasing the durability of multilayer electrochemical systems capable of reversibly inserting ions, most particularly electrochromic systems, without encountering the drawback mentioned above.
Another object of the present invention is to provide a simplified method of manufacturing such electrochromic systems.
Briefly, these objects and other objects of the present invention as hereinafter will become more readily apparent can be attained in an electrochromic device which includes at least one substrate, at least one electroconductive layer, at least one electrochemically active layer capable of reversibly inserting ions, especially cations such as H.

- type, and an electrolyte.
The electrolyte is a layer or a multilayer stack comprising at least one layer made of an ionically conductive material capable of reversibly inserting the ions but whose overall degree of oxidation is maintained essentially constant, which layer will be denoted for simplicity throughout the rest of the description by the term "layer A".
