(EN) NONAQUEOUS ELECTROLYTE POWER STORAGE ELEMENT
(FR) ÉLÉMENT DE STOCKAGE D'ÉNERGIE À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解質蓄電素子
Abstract
(EN) A nonaqueous electrolyte power storage element according to an aspect of the present invention comprises a negative electrode having a negative electrode active material layer containing an acrylic resin, a positive electrode, a first separator layer, and a second separator layer. The first separator layer is interposed between the negative electrode and the positive electrode. The second separator layer is interposed between the negative electrode and the first separator layer. The porosity of the second separator layer is higher than that of the first separator layer.
(FR) Un élément de stockage d'énergie à électrolyte non aqueux selon un aspect de la présente invention comprend une électrode négative ayant une couche de matériau actif d'électrode négative contenant une résine acrylique, une électrode positive, une première couche de séparateur et une seconde couche de séparateur. La première couche de séparateur est interposée entre l'électrode négative et l'électrode positive. La seconde couche de séparateur est interposée entre l'électrode négative et la première couche de séparateur. La porosité de la seconde couche de séparateur est supérieure à celle de la première couche de séparateur.
(JA) 本発明の一側面に係る非水電解質蓄電素子は、アクリル樹脂を含む負極活物質層を有する負極と、正極と、第一セパレータ層と、第二セパレータ層とを備えており、上記第一セパレータ層は上記負極及び上記正極間に介在し、上記第二セパレータ層は上記負極及び上記第一セパレータ層間に介在し、上記第二セパレータ層の空孔率が上記第一セパレータ層よりも高い。
