Provided is a method for manufacturing an all-solid-state lithium ion secondary battery, which comprises: a step for preparing a positive electrode that is formed of an integrated sintered body that is provided with a positive electrode active material plate, which contains a positive electrode active material that is composed of a lithium composite oxide, and an internal collector that is embedded within the positive electrode active material plate; and a step for obtaining a stacked all-solid-state lithium ion secondary battery, which is provided with an assembled battery that is composed of two unit cells, by sequentially laminating a solid electrolyte and a negative electrode on both surfaces of the positive electrode. This method enables integration by sequentially laminating the solid electrolyte and the negative electrode, while effectively suppressing cracks of the positive electrode plate. Consequently, there can be obtained a stacked all-solid-state lithium ion secondary battery with high yield. |
