Document Type and Number:
WIPO Patent Application WO/2023/189892
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a solid-state secondary battery capable of suppressing the uneven depositing of metal in a negative electrode interface in the solid-state secondary battery, and capable of improving cycling characteristics. The means for solving the problem is a solid-state secondary battery having a positive electrode layer, a negative electrode layer including at least a negative electrode current collector, a solid electrolyte layer containing a solid electrolyte material, and an intermediate layer provided between the negative electrode layer and the solid electrolyte layer. The voidage of the intermediate layer is greater than the voidage of the solid electrolyte layer.
