Title
(EN) ELECTRODE STRUCTURE OF LITHIUM BATTERY
(FR) STRUCTURE D'ÉLECTRODE DE BATTERIE AU LITHIUM
(ZH) 锂电池的电极结构
Abstract
(EN)
An electrode structure of lithium battery, which electrically connects a positive electrode and a negative electrode in a lithium battery shell outwards, includes a cover body (100) and at least one sheet metal electrode body (200), an enwrapped portion (210) of which is provided in the cover body (100). The both ends of the portion enwrapped (210) are formed into bends (201, 202) respectively, and a connecting portion (220) and an output portion (230) formed by extending from the bends (201, 202) respectively are protruded from the surface of the cover body (100). The conductive electrode structure of lithium battery is formed by an enwrapping and indirect penetration way, which effects that the conductive portion of the electrode is sealed.
(FR)
L'invention concerne une structure d'électrode de batterie au lithium, destinée à connecter électriquement une électrode positive et une électrode négative dans une enveloppe de batterie au lithium vers l'extérieur. La structure selon l'invention comprend un corps de couvercle (100) et au moins un corps d'électrode métallique en feuille (200) dont une partie enveloppée (210) est située dans le corps de couvercle (100). Les deux extrémités de la partie enveloppée (210) forment respectivement un coude (201,202), et une partie connexion (220) et une partie sortie (230) formées respectivement par extension à partir des coudes (201,202) font saillie de la surface du corps de couvercle (100). Cette structure d'électrode conductrice de batterie au lithium est formée par enveloppement et pénétration indirecte, ce qui a pour effet de sceller la partie conductrice de l'électrode.
