摘要： A battery includes an electrode collector, two electrode active material layers disposed on both principal surfaces of the electrode collector, two solid electrolyte layers each disposed on a side of a corresponding one of the two electrode active material layers that is disposed on the opposite side of the electrode collector, two counter-electrode active material layers each disposed on a side of a corresponding one of the two solid electrolyte layers that is disposed on the opposite side of the corresponding one of the two electrode active material layers, two counter-electrode collectors each disposed on a side of a corresponding one of the two counter-electrode active material layers that is disposed on the opposite side of the corresponding one of the two solid electrolyte layers, and a first insulating layer that covers side surfaces of the two counter-electrode collectors, the two counter-electrode active material layers, the two solid electrolyte layers, and the two electrode active material layers. A first region not covered with any of the two electrode active material layers is provided at ends of both principal surfaces of the electrode collector. A second region not covered with any of the two counter-electrode collectors is provided at an end of a principal surface of each of the two counter-electrode active material layers that faces toward a corresponding one of the counter-electrode collectors. The first insulating layer covers the second region. The electrode collector projects from an outer surface of the first insulating layer.

摘要： A laminated battery includes a plurality of battery cells which are laminated and a current collecting lead. Each of the plurality of battery cells includes a positive electrode current collector, a solid electrolyte layer, a positive electrode active material layer disposed between the positive electrode current collector and the solid electrolyte layer, a negative electrode current collector, and a negative electrode active material disposed between the positive electrode active material and the negative electrode current collector. The battery cells include first and second battery cells adjacent to each other. At least the second battery cell has a side surface inclined with respect to a laminating direction of the battery cells. The first battery cell has a surface facing the second battery cell and including an exposed surface not in contact with the second battery cell. At least part of the exposed surface overlaps at least part of the side surface of the second battery cell viewed from the laminating direction. The current collecting lead is connected to the exposed surface.

The surface facing the second battery cell includes an exposed surface that is not in contact with the second battery cell. At least part of the exposed surface does not overlap the second battery cell when viewed from a laminating direction of the plurality of battery cells. The current collecting lead is connected to the exposed surface.
