Title (EN) PRE-LITHIATION METHOD FOR ANODE FOR SECONDARY BATTERY
(FR) PROCÉDÉ DE PRÉ-LITHIATION D'ANODE DE BATTERIE SECONDAIRE
(KO) 이차전지용 음극의 전리튬화 방법
Abstract:
(EN) The present invention relates to a pre-lithiation method for an electrode for a secondary battery, comprising: a first step of pre-lithiating an electrode in an electrolyte by allowing a lithium metal to directly come in contact therewith and by applying pressure thereto; and a second step of peeling off the lithium metal, and then, performing a stabilizing process by applying pressure to the pre-lithiated electrode. The electrode for a secondary battery, which has passed through the pre-lithiation step, provided in the present invention, alleviates a volume change of the electrode such that a contact loss of the electrode is reduced.
(FR) La présente invention concerne un procédé de pré-lithiation d'une électrode d'une batterie secondaire, comprenant : une première étape de pré-lithiation d'une électrode dans un électrolyte en permettant que du lithium métallique vienne directement en contact avec celle-ci et en lui appliquant une pression; et une seconde étape consistant à peler le lithium métallique, puis à réaliser un traitement de stabilisation par application d'une pression sur l'électrode pré-lithiée. L'électrode d'une batterie secondaire, qui a passé l'étape de pré-lithiation, fournie dans la présente invention, atténue un changement de volume de l'électrode de sorte à réduire une perte de contact de l'électrode.
(KO) 본 발명은 전해액 중에서 전극에 리튬 금속을 직접 접촉시키며 압력을 가하여 전리튬화하는 제 1 단계; 및 상기 리튬 금속을 떼어낸 후, 전리튬화된 전극에 압력을 가하여 안정화 과정을 수행하는 제 2 단계; 를 포함하는 이차전지용 전극의 전리튬화 방법이다. 본 발명에서 제공하는 전리튬화 단계를 거친 이차전지용 전극은 전극의 부피 변화를 완화하고, 그에 따라 전극의 접촉 손실(Contact Loss)을 감소시키는 효과가 있다.
