摘要： Self-protective current collector with sideways collection, for thin-film electrochemical generator with polymeric solid electrolyte, utilising electrodes operating with respect to alkaline or alkaline-earth ions. The collector includes an insulating plastic backing film of between approximately 1 and 30 microns thickness, the film being chosen for its compatibility with the chemical environment of the generator and treated as needed for adhesion to at least one of its faces, a conductive metal coating with a thickness of less than approximately 10 microns, adhering to at least one face of the insulating backing film, chosen for its compatibility with the corresponding electrode material of the generator, and characterised in that its conductive surface is divided into a multitude of distinct adjacent zones, each zone being electrically isolated by non-conductive borders with the exception of at least one conductive bridge of small cross-section and linked to a common conductive side margin allowing sideways collection of the set of distinct zones. The nature and electrical resistance of the conductive bridges are chosen so as to allow, on the one hand, the passage of currents corresponding to the maximum currents provided for each of the individual collection zones of the anticipated generator and, on the other hand, to limit, in the case of an accidental short-circuit inside a zone, the maximum current received by this zone coming from the set of zones of the generator. Production process for this collector, collector-electrode assembly and generator using the collector or the collector-electrode assembly.

摘要： Collecteur de courant auto-protecteur, à collection latérale, pour générateur électrocchimique film mince à électrolyte solide polymère, utilisant des électrodes fonctionnant par rapport aux ions alcalins ou alcalino-terreux. Le collecteur comporte un film support plastique isolant d'épaisseur comprise entre environ 1 et 30 microns, choisi pour sa compatibilité avec l'environnement chimique du générateur et traité au besoin pour l'adhésion sur au moins une de ses faces, un revêtement métallique conducteur, d'épaisseur inférieure à environ 10 microns, adhérent à au moins une face du film support isolant, choisi pour sa compatibilité avec le matériau d'électrode correspondant du générateur, et caractérisé en ce que sa surface conductrice est divisée en une multitude de plages distinctes adjacentes, chaque plage étant électriquement isolée par des bordures non-conductrices à l'exception d'au moins un pont conducteur de faible section relié à une marge latérale commune conductrice permettant une collection latérale de l'ensemble des plages distinctes. La nature et la résistance électrique des ponts conducteurs sont choisis de façon à permettre d'une part, le passage de courants correspondants aux courants maximum prévus pour chacune des plages individuelles de collection du générateur anticipé et à limiter d'autre part, en cas de court-circuit accidentel à l'intérieur d'une plage, le courant maximum reçu par cette plage en provenance de l'ensemble des plages du générateur. Procédé de préparation de ce collecteur, ensemble collecteur-électrode et générateur utilisant le collecteur ou l'ensemble collecteur-électrode.
