Abstract:
(EN) Provided is a method for easily and surely removing a protrusion from the surface of an active material layer formed during a vacuum process upon production of an electrochemical element electrode.  The method for manufacturing an electrochemical element electrode includes: a first step which uses a vacuum process to form on a collector, an active material layer which can occlude and emit lithium; a second step which makes the active material layer to occlude the lithium; and a third step which removes the protrusion from the surface of the active material layer which has occluded the lithium.
(FR) L'invention porte sur un procédé permettant d'éliminer de façon aisée et sûre une saillie de la surface d'une couche de matériau actif formée durant un traitement sous vide lors de la production d'une électrode d'élément électrochimique. Le procédé de fabrication d'une électrode d'élément électrochimique comprend : une première étape qui fait appel à un traitement sous vide pour former sur un collecteur une couche de matériau actif qui peut fixer et émettre du lithium ; une deuxième étape qui amène la couche de matériau actif à fixer le lithium ; et une troisième étape qui élimine la saillie de la surface de la couche de matériau actif qui a fixé le lithium.
(JA) 電気化学素子用電極を製造するにあたって、真空プロセスにて生じた、活物質層表面の突起物を容易かつ確実に除去する方法を提供する。電気化学素子用電極の製造において、リチウムの吸蔵及び放出が可能な活物質層を集電体上に真空プロセスで形成する第1の工程と、前記活物質層にリチウムを吸蔵させる第2の工程と、前記リチウムを吸蔵した活物質層表面の突起物を除去する第3の工程とを行う。
