Summary:Provided are an all-solid-state secondary battery, an all-solid-state secondary battery structure, and a method for manufacturing an all-solid-state secondary battery, the battery comprising: a positive electrode layer; a negative electrode layer; and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer, wherein the positive electrode layer includes a positive electrode current collector and a positive electrode active material layer disposed on one surface or both surfaces of the positive electrode current collector, and the negative electrode layer includes a negative electrode current collector, a first negative electrode active material layer disposed on the negative electrode current collector, and an inactive member disposed so as to surround the side surface of the positive electrode layer. The inactive member includes a position determination part configured to determine the position of the inactive member on the solid electrolyte layer. L'invention concerne une batterie secondaire entièrement solide, une structure de batterie secondaire entièrement solide, et un procédé de fabrication d'une batterie secondaire entièrement solide, la batterie comprenant : une couche d'électrode positive; une couche d'électrode négative; et une couche d'électrolyte solide interposée entre la couche d'électrode positive et la couche d'électrode négative, la couche d'électrode positive comprenant un collecteur de courant d'électrode positive et une couche de matériau actif d'électrode positive disposée sur une surface ou les deux surfaces du collecteur de courant d'électrode positive, et la couche d'électrode négative comprenant un collecteur de courant d'électrode négative, une première couche de matériau actif d'électrode négative disposée sur le collecteur de courant d'électrode négative, et un élément inactif disposé de façon à entourer la surface latérale de la couche d'électrode positive. L'élément inactif comprend une partie de détermination de position conçue pour déterminer la position de l'élément inactif sur la couche d'électrolyte solide. 양극층; 음극층; 및 상기 양극층과 상기 음극층 사이에 배치된 고체전해질층을 포함하며, 상기 양극층이 양극집전체 및 상기 양극집전체의 일면 또는 양면 상에 배치된 양극활물질층을 포함하며, 상기 음극층이 음극집전체 및 상기 음극집전체 상에 배치된 제1 음극활물질층을 포함하며, 상기 양극층의 측면을 둘러싸며 배치된 불활성 부재(inactive member)를 포함하며, 상기 불활성 부재가, 상기 고체전해질층 상에서 상기 불활성 부재의 위치를 결정하도록 구성된 위치 결정부를 포함하는, 전고체 이차전지, 전고체 이차전지 구조체, 및 전고체 이차전지 제조방법이 제시된다.
