摘要： Provided is an all-solid-state lithium battery including an oriented positive electrode plate composed of an oriented polycrystalline body made of lithium transition metal oxide grains, a solid electrolyte layer, a negative electrode layer, and an end insulator insulating and coating ends of the oriented positive electrode plate. The surface of the end insulator and the surface of the oriented positive electrode plate adjacent the solid electrolyte layer form one continuous surface no step exists. Alternatively, the height of the surface of the end insulator adjacent the solid electrolyte layer is lower than that of the surface of the oriented positive electrode plate adjacent the solid electrolyte layer to form a discontinuous surface with proviso that a step between the end insulator and the surface of the oriented positive electrode plate adjacent the solid electrolyte layer is smaller than the thickness of the solid electrolyte layer.

摘要： Provided is a battery-equipped device including a substrate, a device disposed on the substrate, an all-solid-state battery disposed such that the planar shape conforms to the periphery of the device on the substrate and at least partially having a complementary outer edge shape that conforms to the entire or a part of the outer edge shape of the device, and interconnections connecting the device and the all-solid-state battery. The all-solid-state battery includes a positive electrode layer containing an oriented polycrystalline positive-electrode active material composed of lithium transition metal oxide particles oriented in a certain direction, a solid electrolyte layer composed of a lithium-ion conductive material, and a negative electrode layer containing a negative-electrode active material. The present invention can provide a battery-equipped device that can significantly increase the degree of freedom of design and can output necessary electric power in a minimum space.
