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.

All-solid-state battery and method for manufacturing the same

A composite resin molded product of the invention is a composite resin molded product, including: a main agent resin; and a plurality of natural fibers dispersed in the main agent resin. The plurality of natural fibers each contain a microorganism or an enzyme. When the composite resin molded product is 100% by mass, a content rate of the plurality of natural fibers each containing the microorganism or the enzyme in the composite resin molded product is 10% by mass or more and 99% by mass or less. At least one of the plurality of natural fibers is exposed on a surface of the composite resin molded product. At least a part of a surface of the at least one of the plurality of natural fibers is coated with a hydrolyzable coating resin.

Composite resin molded product with adjusted decomposition rate, and production method therefor

An electrode includes a collector, and an active material mixture layer located on the collector and containing first particles, second particles, first active material particles, and second active material particles. The active material mixture layer includes a first mixture layer located on the collector and containing the first particles and the first active material particles, and a second mixture layer located on the first mixture layer and containing the second particles and the second active material particles. The active material mixture layer has a boundary in which the first active material particles and the second active material particles are in contact with each other in a discontinuous state at least in part, in a cross-sectional view of the electrode.
