Resumen de: CN121444212A
In a secondary battery provided with a solid electrolyte between a negative electrode and a positive electrode, there is a problem of cycle deterioration in which the capacity is reduced due to a charge-discharge cycle. Consequently, a secondary battery in which deterioration of cycle characteristics of the secondary battery due to a change in the volume of the electrode can be suppressed is achieved. As a means for this purpose, a secondary battery is used which has a current collector, a positive electrode, and a solid electrolyte that are laminated in this order, and which is provided with a conductive layer that is present between the current collector and the positive electrode. Here, the positive electrode is a conversion electrode, and the conductive layer has a lower conductivity than the current collector. When a center portion and an end portion of the conductive layer in a direction along a surface of the current collector opposing the conductive layer are compared, a thickness of the center portion of the conductive layer is greater than a thickness of the end portion of the conductive layer.
