Abstract
(EN)
[Problem] To provide an electrochemical device which has excellent productivity and includes an electrode in which an electrode active material layer hardly falls off. [Solution] This electrochemical device comprises an electrode and an electrolyte. The electrode includes: a current collector which is metal foil; an undercoat layer which is formed on the main surface of the current collector and has irregularities; and an active material layer which is formed on the undercoat layer and contains an active material. The electrode is immersed in the electrolyte.

Le problème décrit par la présente invention est de fournir un dispositif électrochimique qui présente une excellente productivité et comprend une électrode dans laquelle une couche de matériau actif d'électrode tombe difficilement. La solution selon l'invention porte sur un dispositif électrochimique qui comprend une électrode et un électrolyte. L'électrode comprend : un collecteur de courant qui est une feuille métallique ; une sous-couche qui est formée sur la surface principale du collecteur de courant et présente des irrégularités ; et une couche de matériau actif qui est formée sur la sous-couche et contient un matériau actif. L'électrode est immergée dans l'électrolyte.
