Abstract
(EN) A winding type battery (10) comprises: an electrode body (11) formed by winding a positive electrode (12) and a negative electrode (13) with a separator (14) interposed therebetween; a positive electrode lead (16) attached to a positive electrode collector body (30); negative electrode leads (17, 18) attached to a negative electrode collector body (40); and a center pin (19) provided at the winding center of the electrode body (11) and sticking into the electrode body (11) when the electrode body (11) is crushed. At least at the most inner circumference portion of the electrode body (11), the positive electrode (12) and the negative electrode (13) have respective inner-end-exposed regions (32, 42) where the active material layers are not formed and the collector body surfaces are exposed. The negative electrode lead (18) is attached to the inner-end-exposed region (42).
(FR) La batterie à enroulement (10) de l'invention est équipée : d'un corps d'électrode (11) dans lequel une électrode positive (12) et une électrode négative (13) sont enroulées avec un séparateur (14) pour intermédiaire; d'un conducteur d'électrode positive (16) installé sur un collecteur d'électrode positive (30); de conducteurs d'électrode négative (17, 18) installés sur un collecteur d'électrode négative (40); et d'une tige centrale (19) qui est agencée au centre de l'enroulement du corps d'électrode (11), et qui perce le corps d'électrode (11) lorsque ce dernier est pressé. L'électrode positive (12) et l'électrode négative (13) présentent chacune une surface de collecteur sans formation de couche de matière active au moins sur la partie périphérique la plus interne du corps d'électrode (11), laquelle surface de collecteur possède une région exposition d'extrémité interne (32, 42), et le conducteur d'électrode négative (18) est installé dans la région exposition d'extrémité interne (42).
(JA)  巻回型電池10は、正極12と負極13とがセパレータ14を介して巻回された電極体11と、正極集電体30に取り付けられた正極リード16と、負極集電体40に取り付けられた負極リード17,18と、電極体11の巻回中心に設けられ、電極体11が押し潰されたときに電極体11に突き刺さるセンターピン19とを備える。正極12及び負極13は、電極体11の少なくとも最内周部に、各活物質層が形成されず各集電体表面が露出した内端露出領域32,42をそれぞれ有し、内端露出領域42に負極リード18が取り付けられる。
