Abstract
(EN) This power storage element comprises: a wound electrode body in which lithium manganate is contained as a main component in a positive electrode active material; and a container in which the wound electrode body is housed. The wound electrode body includes a composite layer formation portion in which a composite layer is formed and a composite layer non-formation portion which is positioned at least at one end in a first direction that is parallel to a winding axis. The ratio of the dimension of the wound electrode body in the first direction to the dimension of the wound electrode body in a second direction that is orthogonal to the first direction in a plan view is 1.45 or more.
(FR) Cet élément de stockage d'énergie comprend : un corps d'électrode enroulé dans lequel du manganate de lithium est contenu comme composant principal dans un matériau actif d'électrode positive ; et un récipient dans lequel le corps d'électrode enroulé est logé. Le corps d'électrode enroulé comprend une partie de formation de couche composite dans laquelle une couche composite est formée et une partie de non-formation de couche composite qui est positionnée au moins à une extrémité dans une première direction qui est parallèle à un axe d'enroulement. Le rapport entre la dimension du corps d'électrode enroulé dans la première direction et la dimension du corps d'électrode enroulé dans une seconde direction qui est perpendiculaire à la première direction dans une vue en plan est d'au moins 1,45.
(JA) 蓄電素子は、マンガン酸リチウムを主成分として正極活物質に含有する巻回電極体と、前記巻回電極体を収容する容器と、を備える。前記巻回電極体は、合材層が形成された合材層形成部と、巻回軸に平行な第一方向における少なくとも一端に位置する合材層非形成部とを有する。前記巻回電極体は、平面視における、前記第一方向に直交する第二方向の寸法に対する前記第一方向の寸法の比が１．４５以上である。
