Abstract

L'invention concerne un composant (1) pour accumulateur électrique, comportant : - un substrat (10) comprenant au moins une couche conductrice électrique (30) formant collecteur de courant, - au moins un film séparateur (50), - au moins une couche (40) de particules de matière active d'électrode, en contact électrique avec la couche de collecteur de courant, et disposée entre le substrat et le film séparateur. Conformément à l'invention : - la couche de particules de matière active d'électrode est dépourvue de liant, - au moins l'un du substrat et du film séparateur est hérissé de reliefs de rétention (24) de la couche de particules de matière active d'électrode. L'invention concerne également un procédé de réalisation d'un tel composant et une cellule d'accumulateur d'énergie comprenant un ou plusieurs de tels composants. Applications aux accumulateurs et supercondensateurs du type lithium-ion, lithium métal, lithium-soufre, lithium air et sodium-ion notamment. Figure 6The invention relates to a component (1) for an electric accumulator, comprising: - a substrate (10) comprising at least one electrically conductive layer (30) forming a current collector, - at least one separating film (50), - at least one layer (40) of electrode active material particles, in electrical contact with the current collector layer, and disposed between the substrate and the separator film. According to the invention: - the layer of electrode active material particles is devoid of binder, - at least one of the substrate and of the separator film is bristling with retention reliefs (24) of the layer of material particles active electrode. The invention also relates to a method for producing such a component and to an energy accumulator cell comprising one or more of such components. Applications to accumulators and supercapacitors of the lithium-ion, lithium metal, lithium-sulfur, lithium air and sodium-ion type in particular. Figure 6
