  • Method of manufacturing a multilayer electrochemical assembly comprising an electrolyte between two electrodes, and an assembly made thereby
    Patent number: 5593462
    Abstract: The present invention relates to a method of manufacturing a multilayer electrochemical assembly comprising steps consisting in co-extruding an element comprising at least one electrode film and an electrolyte film based on an ionic conductor polymer through a die so that the electrode is accessible over at least one main face of the extruded element, and over not more than one edge of said element, spiral winding a complex based on the above-specified extruded element to form a structure having, on different faces of its edges, means for making electrical contact respectively with each of the two electrodes, and metallizing said faces of the edge of the structure.
