A stack of batteries is formed, each battery consisting of anode films, polymer electrolyte, cathode, collector and possibly an insulating film, in conditions suitable for constituting a rigid monobloc assembly, the films of which are solidary one with the other. The assembly so formed is then cut to a predetermined shape using a localized abrasive mechanical device without deforming the films constituting the assembly and without inducing permanent short circuits. The cell obtained after cutting has at least one extremity in the form of a uniform cutout, the various films constituting the assembly having undergone no physical deformation, the extremity of the anode films comprising an electronic insulating passivation film.
On prépare un empilement de piles, chacune constituée de films d'anode, d'électrolyte polymère, de cathode, de collecteur et éventuellement d'un film isolant, dans des conditions propres à constituer un assemblage rigide monobloc, dont les films sont solidaires entre eux. On découpe ensuite l'assemblage obtenu sous forme prédéterminée en utilisant un dispositif mécanique abrasif localisé sans déformer les films constituant l'assemblage et sans induire de courts-circuits permanents, La cellule obtenue après découpe comporte au moins une extrémité en forme de découpe uniforme, les divers films constituant l'ensemble n'ayant subi aucune déformation physique, l'extrémité des films d'anode comportant un film de passivation isolant électronique.
