(JA) 電極および二次電池
Abstract:
(EN) Provided is an electrode having a current collector, an active-material layer, a first layer including first particles, and a second layer including second particles, wherein the electrode is characterized in that the average cross-sectional area of the first particles in a plane substantially parallel to the electrode surface is less than the average cross-sectional area of the second particles in a plane substantially parallel to the electrode surface.
(FR) L'invention concerne une électrode ayant un collecteur de courant, une couche de matériau actif, une première couche comprenant des premières particules et une seconde couche comprenant des secondes particules, l'électrode se caractérisant en ce que la surface moyenne de section transversale des premières particules est inférieure, dans un plan sensiblement parallèle à la surface d'électrode, à la surface moyenne de section transversale des secondes particules, dans un plan sensiblement parallèle à la surface d'électrode.
(JA) 集電体と、活物質層と、第一の粒子を含む第一の層と、第二の粒子を含む第二の層と、を有する電極であって、前記電極表面に対して略平行な面における前記第一の粒子の平均断面積が、前記電極表面に対して略平行な面における前記第二の粒子の平均断面積よりも小さいことを特徴とする電極。
