Abstract

L'invention concerne un élément individuel (1) de batterie, comprenant un empilement d'électrodes (7) disposé à l'intérieur d'un boîtier de l'élément, ledit boîtier étant formé par deux parois latérales (2, 3) électro-conductrices, opposées et sensiblement parallèles, et conçues en forme de coque et dotées en bordure d'un flasque (5) périphérique; les flasques (5) étant reliés par liaison de matière en formant ainsi une zone flasque (12) et étant électriquement isolés l'un de l'autre; les pattes (11) d'interconnexion des poles de l'empilement d'électrodes (7) étant reliées de manière électro-conductrice aux parois latérales (2, 3) du boîtier. Selon l'invention, au moins une paroi latérale (2 ou 3) est conçue, au moins par sections, saillante de la zone flasque (12) d'au moins une bordure du boîtier de l'élément; la section (13) de la paroi latérale (2, 3) du boîtier, section saillante de la zone flasque (12), étant coudée en direction d'un espace intérieur (9) de l'élément et en direction d'un fond de coque (10) de la paroi latérale (2, 3) du boîtier, et au moins un élément de fixation (16) étant moulé dans ou sur au moins une section (13) coudée. L'invention concerne en outre une batterie constituée d'une pluralité d'éléments individuels (1).
