Abstract

L’invention concerne un élément électrochimique et son procédé de fabrication, ainsi qu’une batterie comprenant un ou plusieurs éléments électrochimiques, trouvant notamment une application au domaine des éléments électrochimiques ou batteries de type Li-ion. L’élément électrochimique comprend une enveloppe 1 fermée définissant un volume interne à l’intérieur duquel est disposé un faisceau 2 comportant une alternance d'électrodes 3 positives et négatives connectées respectivement à deux bornes de sortie électriques positive et négative et encadrant des séparateurs, le faisceau 2 étant imprégné d'électrolyte. L’enveloppe 1 comprend une paroi de fond 4 présentant une face de fond interne 4a, orientée vers le volume interne, et au moins une paroi latérale 5, 6 présentant une face latérale interne 5a, 6a, orientée vers le volume interne. La face latérale interne 5a, 6a rejoint la face de fond interne 4a en formant sensiblement un angle interne (a). Figure pour l'abrégé : figure 2
