Title (EN) PRODUCTION METHOD FOR ALL-SOLID-STATE LITHIUM BATTERY
(FR) PROCÉDÉ DE FABRICATION DE BATTERIE AU LITHIUM TOUT SOLIDE
(JA) 全固体リチウム電池の製造方法
Abstract:
(EN) Provided is a production method for an all-solid-state lithium battery, said production method comprising: a step for preparing a self-supporting positive electrode plate that has a thickness of 20 µm or more and that comprises a sintered body containing a plurality of crystal grains configured from a positive electrode active material; a step for forming a solid electrolyte layer configured from a lithium ion-conducting material on the positive electrode plate without attaching the positive electrode plate to a current collector; and a step for obtaining a laminate that is a unit cell by forming a negative electrode layer containing lithium on the solid electrolyte layer. This production method makes it possible to reduce various types of stress occurring during formation of the solid electrolyte layer and the negative electrode layer. As a result, it is possible to produce an all-solid-state lithium battery having high energy density at a low cost with high productivity.
(FR) L’invention concerne un procédé de fabrication de batterie au lithium tout solide qui inclut : une étape au cours de laquelle est préparée une plaque d’électrode positive autoportante qui est constituée par un corps fritté contenant une pluralité de particules cristallines configurées par une matière active d’électrode positive, et dont l’épaisseur est supérieure ou égale à 20μm ; une étape au cours de laquelle est formée une couche d’électrolyte solide qui est configurée par un matériau conducteur de lithium-ion sur la plaque d’électrode positive, sans collage de la plaque d’électrode positive sur un collecteur ; et une étape au cours de laquelle est formée une couche d’électrode négative contenant du lithium sur la couche d’électrolyte solide, et un stratifié constituant une batterie unitaire est ainsi obtenu. Selon ce procédé de fabrication, il est possible d’atténuer diverses contraintes produites lors de la formation de la couche d’électrolyte solide et de la couche d’électrode négative, et de fabriquer selon une haute productivité et à bas coût une batterie au lithium tout solide d’une énergie massique plus élevée.
(JA) 全固体リチウム電池の製造方法であって、正極活物質で構成される複数の結晶粒を含む焼結体からなる、厚さ20μm以上の自立した正極板を用意する工程と、正極板を集電体に貼り付けることなく、正極板上にリチウムイオン伝導材料で構成される固体電解質層を成膜する工程と、固体電解質層上にリチウムを含む負極層を形成して、単位電池である積層体を得る工程とを含む、方法が開示される。この製造方法によれば、固体電解質層や負極層の成膜中の各種発生応力を低減させることができ、それにより高エネルギー密度の全固体リチウム電池を高い生産性かつ低コストで製造することができる。
