Title:
ALL-SOLID-STATE LITHIUM-ION SECONDARY BATTERY AND LEAK INSPECTION METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP2022095089
Kind Code:
A
Abstract:
To provide an all-solid-state lithium ion secondary battery capable of performing leak inspection quickly and easily.SOLUTION: An all-solid-state lithium ion secondary battery includes an electrode laminate in which a positive electrode, a solid electrolyte layer, and a negative electrode are alternately laminated, a tab converging unit extending from an electrode, and an exterior film that covers the electrode laminate and the tab converging unit, and the electrode laminate and the tab converging unit are vacuum-packed with the exterior film. For example, there is an inspection recess formed such that the exterior film is followed along an inspection recess formed on the surface of the electrode laminate side, and it is possible to perform leak inspection on the all-solid-state lithium ion secondary battery.SELECTED DRAWING: Figure 2
