Abstract

La structure centrale pour une pile secondaire circulaire au lithium est disposée dans le boîtier de la pile et comprend : un coeur, une électrode et deux ensembles conducteurs fixateurs. Un élément connecteur sert de connexion électrique conductrice pour relier les pièces conductrices pressées au terminal du conducteur positif ou du conducteur négatif. L'élément connecteur est une structure courbée flexible. De cette façon, même s'il y a une erreur de dimension du coeur ou du boîtier, elle peut être compensée par la déformation de l'élément connecteur. La pile peut donc être assemblée avec succès.
