A conductive structure for an electrode assembly of a secondary battery comprises: a core disposed in a case, two lead terminals fixed at both ends of the core, an electrode assembly winding about the core, two clasping structures for enabling the electrode assembly to keep in electrical contact with the lead terminals, and two fixing nuts for fixing these components and the case. The electric connection between the positive lead, the negative lead and the lead terminals is achieved by clasping structures without the use of any welding operation. Therefore, the operation procedure of the present invention is effectively simplified, and the equipment cost is substantially reduced. In addition, the positive and negative leads are in a large area electrical contact with the collecting area, thus relatively reducing the internal resistance.
Structure conductrice pour les électrodes d'une batterie secondaire comprenant un noyau dans un boîtier, deux bornes principales fixées aux extrémités du noyau, un ensemble d'électrodes enroulé autour du noyau, deux fermoirs qui tiennent les électrodes en contact électrique avec les bornes principales et deux écrous pour fixer ces composants au boîtier. Le contact électrique entre la borne positive, la borne négative et les bornes principales s'obtient au moyen des fermoirs, sans la moindre soudure. Ainsi, le mode d'utilisation de l'invention est grandement simplifié et le coût de l'équipement est grandement réduit. De plus, les bornes positive et négative partagent une grande surface de contact électrique avec la zone de collecte, ce qui réduit légèrement la résistance interne.
