| description | Provided is a positive electrode for an all-solid-state lithium ion secondary battery which can reduce the internal resistance of the all-solid-state lithium ion secondary battery. The positive electrode includes an active material layer containing a positive electrode active material and a solid electrolyte material. The positive electrode active material contains secondary particles comprising an aggregate of a plurality of primary particles containing a lithium transition metal composite oxide. A smoothness of the secondary particles is more than 0.73, and a degree of circularity of the secondary particles is more than 0.83. |
