Abstract

L'invention concerne un film composite comprenant : - une première couche métallique (10a, 10b), superposée à une couche à base de polymère (12a, 12b) et solidaire d'une première face de la couche à base de polymère, - une deuxième couche conductrice (32a, 32b), formée sur la couche à base de polymère (12a, 12b), et solidaire d'une deuxième face de la couche à base de polymère, opposée à ladite première face. Conformément à l'invention : - le film présente une pluralité de cuvettes (20) traversant respectivement la couche à base de polymère depuis la deuxième face vers la première face et s'étendant dans la première couche métallique, la pluralité de cuvette (20) conférant à la deuxième face de la couche à base de polymère un relief, et - la deuxième couche conductrice (32a, 32b), tapisse les cuvettes (20) et la deuxième face de la couche à base de polymère, en épousant ledit relief. L'invention concerne également un accumulateur d'énergie électrique (100) utilisant plusieurs de tels films. Application à la réalisation de batteries et de supercondensateurs. Figure 7.The invention relates to a composite film comprising: - a first metallic layer (10a, 10b), superimposed on a polymer-based layer (12a, 12b) and integral with a first face of the polymer-based layer, - a second conductive layer (32a, 32b), formed on the polymer-based layer (12a, 12b), and integral with a second face of the polymer-based layer, opposite to said first face. According to the invention: - the film has a plurality of cuvettes (20) respectively passing through the polymer-based layer from the second face towards the first face and extending into the first metal layer, the plurality of cuvettes (20) giving the second face of the polymer-based layer a relief, and - the second conductive layer (32a, 32b), lines the cups (20) and the second face of the polymer-based layer, matching said relief. The invention also relates to an electric energy accumulator (100) using several such films. Application to the production of batteries and supercapacitors. Figure 7.
