摘要： A laser machining method is a laser machining method for joining a first member containing a first metal and a second member containing a second metal different from the first metal, the method including a first step of forming a joint in which the first metal and the second metal are melted by performing scanning with a first laser beam, and a second step of stirring a metal structure near the joint by performing scanning, on a rear side in a scanning direction of the first laser beam, with a second laser beam having a beam diameter larger than a bean diameter of the first laser beam and having a lower power density than a power density of the first laser beam.

摘要： An all-solid-state battery has a structure in which a positive electrode current collector, a positive electrode layer containing a positive electrode active material and a solid electrolyte, a solid electrolyte layer containing a solid electrolyte, a negative electrode layer containing a negative electrode active material and a solid electrolyte, and a negative electrode current collector are stacked in this order. The solid electrolyte layer has a repeating structure in which a low porosity portion and a high porosity portion having a higher porosity than a porosity of the low porosity portion are repeated in an in-plane direction.

摘要： Provided herein is a solid-state battery having high volume energy density, as well as a method of manufacture of such a solid-state battery. A solid-state battery 100 is a laminate including a first collector layer 1, a positive electrode layer 2, a solid electrolyte layer 5, a negative electrode layer 4, and a second collector layer 3, in this order from the top. The solid-state battery 100 satisfies α>90°, β>90°, and α>β, where α is the angle formed in the positive electrode layer 2 by a side surface 2A of the positive electrode layer 2 and the top surface of the solid electrolyte layer 5 underlying the positive electrode layer 2, and β is the angle formed in the negative electrode layer 4 by a side surface 4A of the negative electrode layer 4 and the top surface of the second collector layer 3 underlying the negative electrode layer 4.

摘要： To reduce a width of a modified layer and suppress positional variation of the modified layer, a crystal orientation of a workpiece is measured, a vertical direction with respect to an A-plane of the measured crystal orientation of the workpiece is specified, and a polarization direction of laser light is adjusted so that scanning of laser light is performed along the specified vertical direction with respect to the A-plane of the crystal orientation of the workpiece.

摘要： An all-solid battery is formed by laminating a first current collector, a positive-electrode layer, a solid electrolyte layer, a negative-electrode layer, and a second current collector in this order. The positive-electrode fine particle layer contains positive-electrode active material fine particles having a particle diameter smaller than that of the positive-electrode active material and is formed on a side surface of the positive-electrode layer. The negative-electrode fine particle layer contains negative-electrode active material fine particles having a particle diameter smaller than that of the negative-electrode active material and is formed on a side surface of the negative-electrode layer.

摘要： In a laser processing apparatus and a laser processing method, a laser beam radiated from a laser oscillator is positioned on one minute diffraction pattern or over two or more minute diffraction patterns provided in a diffraction optical element by a moving unit. A laser beam to which a desired beam profile is given is reflected at an angle in which the laser beam is radiated to a target position on a processed object by a scanning unit, and the laser beam is transmitted through the lens unit a position in the Z-axis direction of which is controlled so that a focal point of the lens unit corresponds to the surface of the processed object. The processed object is irradiated with a laser beam converged by the lens unit and having a desired laser beam profile to realize desired processing.
