Title (EN) ELECTRODE AND POWER STORAGE ELEMENT
(FR) ÉLECTRODE ET ÉLÉMENT DE STOCKAGE D'ÉNERGIE
(JA) 電極及び蓄電素子
Abstract:
(EN) One embodiment of the present invention provides an electrode for a power storage element. The electrode has a conductive base material, an intermediate layer, and an active material layer provided in that order. The intermediate layer includes: a conductive agent; a compound which decomposes at a temperature of 100˚C or higher and generates a gas; and a binder. The content of the compound is at least two times, but not more than 20 times the content of the conductive agent in the intermediate layer, in terms of mass ratio.
(FR) Selon un mode de réalisation, la présente invention concerne une électrode pour un élément de stockage d’énergie. L'électrode comprend un matériau de base conducteur, une couche intermédiaire et une couche de matériau actif disposés dans cet ordre. La couche intermédiaire comprend : un agent conducteur ; un composé qui se décompose à une température supérieure ou égale à 100 °C et génère un gaz ; et un liant. La teneur du composé est au moins deux fois, mais pas plus de 20 fois la teneur de l'agent conducteur dans la couche intermédiaire, en termes de rapport de masse.
(JA) 本発明の一態様は、導電性の基材、中間層及び活物質層をこの順に備え、上記中間層が、導電剤、100℃以上で分解して気体を発生する化合物、及びバインダーを含み、上記中間層における上記導電剤の含有量に対する上記化合物の含有量が、質量比で2倍以上20倍以下である蓄電素子用の電極である。
