Abstract:
(EN) The present invention provides a method for manufacturing a battery cell, comprising the steps of: (i) manufacturing a reference cell configured by an electrolyte, n (n≥2) reference electrodes, and a lithium electrode; (ii) applying a micro current to the reference cell to charge the reference cell, and discharging the reference cell immediately after the charging thereof; (iii) charging the reference cell, up to 40% to 60%, with respect to a capacity which has been discharged in step (ii), thereby simultaneously forming the reference electrodes to have flat potentials; (iv) manufacturing n battery cells by the formed reference electrodes, an electrode assembly, the electrolyte, and a battery case; and (v) measuring, in each of the battery cells, a relative potential between a positive electrode and a formed reference electrode and a relative potential between a negative electrode and the reference electrode.
(FR) La présente invention concerne un procédé de fabrication d'un élément de batterie, comprenant les étapes suivantes : (i) fabrication d'un élément de référence configuré par un électrolyte, n (n ≥ 2) électrodes de référence, et une électrode de lithium; (ii) application d'un micro-courant à l'élément de référence pour charger l'élément de référence, et décharge de l'élément de référence immédiatement après sa charge; (iii) charge de l'élément de référence jusqu'à 40 % à 60 % par rapport à une capacité qui a été déchargée à l'étape (ii), ce qui permet de former simultanément les électrodes de référence pour avoir des potentiels plats; (iv) fabrication de n éléments de batterie par les électrodes de référence formées, un ensemble à électrodes, l'électrolyte, et un boîtier de batterie; et (v) mesure, dans chacun des éléments de batterie, d'un potentiel relatif entre une électrode positive et une électrode de référence formée et d'un potentiel relatif entre une électrode négative et l'électrode de référence.
(KO) 본 발명은 (i) 전해액, n개(n≥2)의 기준 전극 및 리튬 전극으로 구성된 기준 셀을 제조하는 과정; (ii) 기준 셀에 미세 전류를 인가하여 충전시킨 직후, 방전을 수행하는 과정; (iii) 과정(ii)에서 방전된 용량 대비 40% 내지 60% 만큼 기준 셀을 충전하여 기준 전극들을 동시에 평탄 전위로 포메이션하는 과정; (iv) 포메이션된 기준 전극들과 전극조립체, 전해액 및 전지케이스로 n개의 전지셀들을 제조하는 과정; 및 (v) 전지셀들 각각에서 포메이션된 기준 전극과 양극 및 기준 전극과 음극의 상대 전위를 측정하는 과정;을 포함하는 전지셀 제조 방법을 제공한다.
