Abstract
(EN)
Disclosed is a rechargeable button-type soft-pack lithium-ion battery, comprising a shell (1) which is a cylindrical aluminum-plastic composite film structure. The shell (1) is provided with a positive electrode plate (2), a diaphragm (3) and a negative electrode plate (4) therein; the diaphragm (3) being located between the positive electrode plate (2) and the negative electrode plate (4), and the positive electrode plate (2), the diaphragm (3) and the negative electrode plate (4) being rolled into a cylindrical coil core structure and placed inside the shell (1). Electrolyte is further filled between the positive electrode plate (2) and the negative electrode plate (4). The positive electrode plate (2) is further electrically connected to a positive electrode tab (5), and the negative electrode plate (4) is further electrically connected to a negative electrode tab (4). Disclosed is also a processing method for the battery, comprising the steps of molding, assembling, installing and packaging. The battery adopts an aluminum-plastic structure as the shell (1), ensuring more convenient processing and a lighter weight; the battery is sealed by means of a thermoplastic packaging process after assembly, ensuring high installation efficiency and good safety and sealing performance; the positive electrode plate (2), the diaphragm (3) and the negative electrode plate (4) are rolled into the cylindrical coil core structure, ensuring higher production and processing efficiency.

L'invention concerne une pile rechargeable au lithium-ion en sachet souple du type bouton, comprenant une enveloppe (1) qui est une structure de film composite aluminium-plastique cylindrique. Une plaque d'électrode positive (2), une membrane (3) et une plaque d'électrode négative (4) sont disposées dans l'enveloppe (1) ; la membrane (3) étant située entre la plaque d'électrode positive (2) et la plaque d'électrode négative (4), et la plaque d'électrode positive (2), la membrane (3) et la plaque d'électrode négative (4) étant enroulées en une structure de cœur en bobine cylindrique et placées à l'intérieur de l'enveloppe (1). En outre, l'espace entre la plaque d'électrode positive (2) et la plaque d'électrode négative (4) est rempli d'électrolyte. La plaque d'électrode positive (2) est en outre connectée électriquement à une languette d'électrode positive (5), et la plaque d'électrode négative (4) est en outre connectée électriquement à une languette d'électrode négative (4). L'invention concerne également un procédé de traitement pour la pile, comprenant les étapes de moulage, d'assemblage, d'installation et d'emballage. La pile adopte une structure aluminium-plastique comme enveloppe (1), assurant un traitement plus pratique et un poids plus léger ; la pile est étanchéifiée au moyen d'un processus d'emballage thermoplastique après assemblage, assurant une haute efficacité d'installation et de bonnes performances de sécurité et d'étanchéité ; la plaque d'électrode positive (2), la membrane (3) et la plaque d'électrode négative (4) sont enroulées en la structure de cœur en bobine cylindrique, assurant un plus haut rendement de production et de traitement.
