Abstract: Provided is a solid-state battery comprising: electrode laminates, each of the electrode laminates being configured with a solid electrolyte layer and a positive electrode composite layer that are sequentially laminated on a negative electrode current collector; and a positive electrode current collector sandwiched between the electrode laminates. The positive electrode composite layer is provided with a positive electrode insulating frame on an outer perimetric part thereof. When the solid-state battery is viewed from above, an outer perimetric edge of the negative electrode current collector exists inward of an outer perimetric edge of the solid electrolyte layer, and an outer perimetric edge of the positive electrode insulating frame exists at a same position as the outer perimetric edge of the solid electrolyte layer or exists outward of the outer perimetric edge of the solid electrolyte layer.

Abstract: A negative electrode for a lithium ion secondary battery that can realize a lithium ion secondary battery that has both a high capacity and long cycle durability and a lithium ion secondary battery using the negative electrode for a lithium ion secondary battery are provided. A negative-electrode active material layer composes a negative electrode for a lithium ion secondary battery formed as a laminate in which a layer including crystalline carbon and a layer including amorphous carbon are laminated in a specific deposition. Specifically, the negative-electrode active material layer configured by the laminate including a lower layer adjacent to a current collector and an upper layer disposed on the side of the lower layer opposite to the current collector is set and the negative electrode for a lithium ion secondary battery in which the lower layer includes crystalline carbon particles and the upper layer includes amorphous carbon particles is set.
