Battery

Abstract

A battery includes an electrode layer, a counter electrode layer facing the electrode layer, and a solid electrolyte layer located between the electrode layer and the counter electrode layer. The electrode layer includes an electrode current collector and an electrode active material layer located between the electrode current collector and the solid electrolyte layer and having an area smaller than those of the electrode current collector and the solid electrolyte layer in plan view. In a first region including the electrode active material layer and a second region outside the first region in plan view, the solid electrolyte layer covers the outside of the electrode active material layer and is in contact with the electrode current collector in the second region, and the electrode current collector or the solid electrolyte layer includes at least one structural defect portion in a line shape in plan view in the second region.
