Summary:The present invention provides a complex solid electrolyte membrane for an all-solid-state battery and an all-solid-state battery including same, the complex solid electrolyte membrane comprising: a phase change layer including a plasticizer and a lithium salt; a porous polymer sheet layer; and a solid polymer electrolyte layer, wherein the phase change layer, the porous polymer sheet layer, the solid polymer electrolyte layer are sequentially stacked, and the phase change layer is arranged to face an anode during the manufacture of an electrode assembly. A complex electrolyte membrane for an all-solid-state battery, of the present invention, can reduce an interfacial resistance to an electrode, increase ion conductivity, and improve battery stability. La présente invention concerne une membrane électrolytique solide complexe pour une batterie entièrement solide et une batterie entièrement solide comprenant celle-ci, la membrane électrolytique solide complexe comprenant : une couche à changement de phase comprenant un plastifiant et un sel de lithium ; une couche de feuille polymère poreuse ; et une couche d'électrolyte polymère solide, la couche à changement de phase, la couche de feuille polymère poreuse, la couche d'électrolyte polymère solide étant empilées séquentiellement, et la couche à changement de phase étant agencée pour faire face à une anode pendant la fabrication d'un ensemble d'électrodes. Une membrane électrolytique complexe pour une batterie entierement solide, selon la présente invention, peut réduire une résistance interfaciale à une électrode, augmenter la conductivité ionique et améliorer la stabilité de la batterie. 본 발명은 가소제와 리튬염을 포함하는 상변환층; 다공성 고분자 시트층; 및 고체 고분자 전해질층을 포함하며, 상기 상변환층, 상기 다공성 고분자 시트층, 상기 고체 고분자 전해질층은 순차적으로 적층된 것이고, 상기 상변환층은 전극 조립체 제조시 음극과 대면하도록 배치되는 것인, 전고체 전지용 복합 고체 전해질 막 및 이를 포함하는 전고체 전지를 제공한다. 본 발명은 전고체 전지용 복합 전해질 막은 전극과의 계면 저항을 줄이고 이온 전도도를 높이며, 전지의 안전성을 개선시킬 수 있다.
