Abstract:
(EN) Provided is an electrochemical device electrode 2 containing a current collector 9 and an active material layer 10 comprising an active material coated on the current collector 9, wherein the active material layer 10 includes a lower active material layer 10a closely bonded on the current collector 9, and an upper active material layer 10b disposed on the current collector 9 via the lower active material layer 10a. The lower active material layer 10a is thinner than the upper active material layer 10b. In the lengthwise direction of the current collector 9, the terminal part of the upper active material layer 10b is either coincident with the terminal part of the lower active material layer 10a or is positioned before the terminal part of the lower active material layer 10a.
(FR) L’invention concerne une électrode de dispositif électrochimique 2 qui contient un collecteur de courant 9 et une couche de matériau actif 10 comprenant un matériau actif déposé sur le collecteur de courant 9, la couche de matériau actif 10 comprenant une couche de matériau actif inférieure 10a, reliée étroitement au collecteur de courant 9, et une couche de matériau actif supérieure 10b disposée sur le collecteur de courant 9 par l’intermédiaire de la couche de matériau actif inférieure 10a. La couche de matériau actif inférieure 10a est plus mince que la couche de matériau actif supérieure 10b. Dans le sens de la longueur du collecteur de courant 9, la partie terminale de la couche de matériau actif supérieure 10b soit coïncide avec la partie terminale de la couche de matériau actif inférieure 10a, soit est positionnée avant la partie terminale de la couche de matériau actif inférieure 10a.
(JA) 集電体9と、集電体9に塗布されている活物質からなる活物質層10とを含む、電気化学デバイス用電極2において、活物質層10は、集電体9の上に密着する下活物質層10aと、下活物質層10aを介して集電体9の上に配置されている上活物質層10bとを含む。下活物質層10aの厚さは、上活物質層10bの厚さよりも薄い。集電体9の長手方向において、上活物質層10bの終端部は下活物質層10aの終端部と一致するか、または下活物質層10aの終端部よりも手前に位置する。
