Abstract: An all-solid-state battery has a structure including a positive electrode current collector; a positive electrode layer containing a positive electrode active material, a first solid electrolyte, a second solid electrolyte, and a conductive fiber; a solid electrolyte layer containing a fourth solid electrolyte; a negative electrode layer containing a negative electrode active material and a third solid electrolyte; and a negative electrode current collector. These are stacked in this order. The positive electrode layer includes: a fiber-containing region that coats the positive electrode active material and that contains the conductive fiber and the first solid electrolyte; and a fiber-free region that is located in a gap surrounded by the positive electrode active material coated by the fiber-containing region. The fiber-free region is free of the conductive fiber, and contains the second solid electrolyte.

Abstract: 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.

Abstract: A catalyst, includes: a carbon support that possesses functional groups including a carboxyl group; and a metal that is supported onto the carbon support, wherein the proportion of the carboxyl group to the functional groups is 10% or higher. A method for producing a catalyst includes: (i) supporting metal particles onto a carbon support; (ii) bringing the carbon support into contact with an acid solution; and (iii) calcining the carbon support after Step (ii), wherein the carbon support included in the produced catalyst possesses functional groups including a carboxyl group, and the proportion of said carboxyl group to the functional groups is 10% or higher.
