Abstract
(EN) A method for manufacturing an all-solid-sate battery, according to the present invention, controls the reaction between a negative electrode and a solid electrolyte membrane during pressing processing for binding between electrode elements. Particularly, if lithium metal is included as the negative electrode, and a sulfide-based solid electrolyte material is included as the solid electrolyte membrane, the present invention can control the reaction between the lithium metal and the sulfide-based solid electrolyte material. Also, an all-solid-state battery manufactured according to the method for manufacturing an all-solid-state battery of the present invention exhibits low porosity in the positive electrode and the solid electrolyte membrane, has a low short circuit occurrence rate as the solid electrolyte membrane and the negative electrode, which is the lithium metal, do not react with each other, and has the effect of an improved battery manufacturing yield.
(FR) Procédé de fabrication d'une batterie entièrement solide qui, selon la présente invention, commande la réaction entre une électrode négative et une membrane électrolytique solide pendant un traitement de pressage pour liaison entre des éléments d'électrode. En particulier, si un métal lithium est compris en tant qu'électrode négative, et qu'un matériau d'électrolyte solide à base de sulfure est compris en tant que membrane électrolytique solide, la présente invention peut commander la réaction entre le métal lithium et le matériau électrolytique solide à base de sulfure. De plus, une batterie entièrement solide fabriquée selon le procédé de fabrication d'une batterie entièrement solide de la présente invention présente une faible porosité dans l'électrode positive et la membrane électrolytique solide, présente un faible taux d'apparition de court-circuits comme la membrane électrolytique solide et l'électrode négative, qui est le métal lithium, ne réagissent pas l'une avec l'autre, et a pour effet d'améliorer un rendement de fabrication de la batterie.
(KO) 본 발명에 따른 전고체 전지 제조 방법은 전극 소자간 결착을 위한 가압 공정시 음극과 고체 전해질막 사이의 반응이 제어된다. 특히 음극으로 리튬 금속을 포함하고 고체 전해질막으로 황화물계 고체 전해질 재료를 포함하는 경우 리튬 금속과 황화물계 고체 전해질 재료 사이의 반응을 제어할 수 있다. 또한, 본 발명의 전고체 전지 제조 방법에 따라 제조된 전고체 전지는 양극과 고체 전해질막의 기공도가 낮으며 고체 전해질막과 리튬 금속인 음극이 반응하지 않아 단락 발생이 낮고 전지 제조 수율이 개선되는 효과가 있다.
