All solid secondary battery all solid secondary battery structure and Preparation method for all solid secondary battery

According to the present invention, an all-solid-state secondary battery, an all-solid-state secondary battery structure, and a method for manufacturing an all-solid-state secondary battery are presented. The all-solid-state secondary battery comprises: a cathode layer; an anode layer; and a solid electrolyte layer disposed between the cathode layer and the anode layer. The cathode layer includes a cathode current collector and a cathode active material layer disposed on one or both sides of the cathode current collector, and the anode layer includes an anode current collector and a first cathode active material layer disposed on the anode current collector. In addition, the all-solid-state secondary battery further includes an inactive member disposed to surround a side surface of the cathode layer, wherein the inactive member contains a position determining portion formed to determine a position of the inactive member on the solid electrolyte layer. Accordingly, the all-solid-state secondary battery can be easily manufactured which is prevented from short-circuiting and has improved cycle characteristics. 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.
