Document Type and Number:
WIPO Patent Application WO/2021/125337
Kind Code:
A1
Abstract:
Provided is a solid-state battery formed by comprising a solid-state battery laminate obtained by lamination of a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer, the solid-state battery being equipped with external terminals which are of a positive electrode terminal and a negative electrode terminal and which are provided on the respective opposing side surfaces of the solid-state battery laminate. In said solid-state battery, electrode layers, which are the positive electrode layer and the negative electrode layer, are formed by comprising active material portions including an active material to the electrode layers, and current collector portions having a relatively small active material density with respect to the active material portions. Further, the electrode layers have an end-surface current-collecting structure in which current is collected at the current collector portions provided on end surfaces of the active material portions.
