Title (EN) METHOD FOR MANUFACTURING ELECTROCHEMICAL DEVICE
(FR) PROCÉDÉ DE FABRICATION DE DISPOSITIF ÉLECTROCHIMIQUE
(KO) 전기화학소자의 제조 방법
Abstract:
(EN) The objective of the present invention is to provide a method for manufacturing an electrochemical device, which comprises a preprocessing step for discharging a battery by applying external power to the battery before a step for initially charging and activating the battery, thereby removing a by-product layer on a surface of a cathode. The present invention can improve the cycle life of the electrochemical device by comprising the preprocessing step for discharging the battery before the step for initially activating the battery.
(FR) La présente invention a pour objet de fournir un procédé de fabrication d'un dispositif électrochimique, lequel comprend une étape de prétraitement permettant la décharge d'une batterie par application d'un courant externe à la batterie avant une étape de charge et d'activation initiale de la batterie, ce qui permet d'éliminer une couche de sous-produit sur une surface d'une cathode. La présente invention permet d'améliorer la durée de vie du dispositif électrochimique à l'aide de l'étape de prétraitement permettant la décharge de la batterie avant l'étape d'activation initiale de la batterie.
(KO) 본 발명의 목적은 전지를 최초 충전하여 활성화시키는 단계 전에, 외부 전력을 인가하여 방전시키는 전처리 단계를 포함함으로써, 음극 표면의 부산물층을 제거하는 전기화학소자의 제조 방법을 제공하는 것이다. 본 발명은 전지의 최초 활성화 단계 전에 방전 전처리 단계를 포함함으로써, 전기화학소자의 사이클 수명을 개선시킬 수 있다.
