Abstract:
(EN) This battery comprises a band-shaped electrode that has been wound into a flat shape. The electrode comprises a collector and an active substance layer provided on the inner surface of the collector. The active substance layer has a first region and a second region whereof the surface area density is lower than that of the first region. The second region is provided at a winding-return portion of the active substance layer.
(FR) La présente invention concerne une batterie comprenant une électrode en forme de bande qui a été enroulée en une forme plate. L'électrode comprend un collecteur et une couche de substance active située sur la surface interne du collecteur. La couche de substance active possède une première région et une seconde région dont la densité de surface est inférieure à la densité de surface de la première région. La seconde région est située au niveau d'une partie de retour d'enroulement de la couche de substance active.
(JA) 電池は、扁平状に巻回された帯状の電極を備える。電極は、集電体と、集電体の内側面に設けられた活物質層とを備える。活物質層は、第1領域と、この第1領域よりも面積密度が低い第2領域とを有し、第2領域は、活物質層の巻き返し部に設けられている。
