Abstract

Ce bloc (10) de cellules de batterie comprend une pluralité d’accumulateurs (1) souples, juxtaposés les uns aux autres, comprenant chacun deux languettes disposées chacune dans le plan et d’un côté opposé dudit accumulateur et formant ses pôles électriques. Ledit bloc (10) comprend en outre : une pluralité de paires d’éléments de fixation (13) empilées comprenant chacune un premier élément de fixation (14) supportant une première languette (15) d’un accumulateur, et un deuxième élément de fixation (16) supportant une deuxième languette (17) dudit accumulateur, ladite paire d’éléments de fixation étant destinée à maintenir en contact avec pression lesdites languettes contre une paire adjacente d’éléments de fixation et à constituer des liaisons électriques avec lesdites languettes,des couches (11) comprenant un matériau isolant électriquement disposées entre chaque paire d’accumulateurs adjacents, etdes moyens de fixation amovible permettant d’assembler de façon démontable les éléments de fixation (13).
