Abstract

La présente invention porte, selon divers modes de réalisation, sur un dispositif électronique qui peut comprendre : un rouleau de gelée ayant une structure dans laquelle une plaque d'électrode positive, une plaque d'électrode négative et un séparateur sont enroulés ensemble ; une poche de batterie destinée à recevoir le rouleau de gelée ; une batterie comprenant une première languette d'électrode raccordée électriquement à la plaque d'électrode positive du rouleau de gelée et retirée de la poche de batterie, une seconde languette d'électrode raccordée électriquement à la plaque d'électrode négative du rouleau de gelée et retirée de la poche de batterie, et un matériau d'étanchéité disposé au niveau d'une partie à partir de laquelle la première languette d'électrode et la seconde languette d'électrode sont retirées de la poche de batterie, et scellant la poche de batterie ; une carte de circuit imprimé sur laquelle la première languette d'électrode et la seconde languette d'électrode sont raccordées électriquement ; et un circuit de détection qui est positionné sur la carte de circuit imprimé et qui peut mesurer l'état du rouleau de gelée, la première languette d'électrode et la seconde languette d'électrode pouvant s'étendre de telle sorte qu'au moins certaines sections soient pliées de sorte à être raccordées électriquement à la carte de circuit imprimé. Divers autres modes de réalisation sont possibles.
