Abstract: The invention is a nonwoven fabric characterized by satisfying 0.25?(L2/V)?10, when an average fiber diameter of all fibers is L (?m) and a volume per m2 is V (cm3). The nonwoven fabric leads to a solid electrolyte-carrying sheet in which solid electrolyte particles are carried between fibers and which can achieve a good balance among thickness reduction, powder falling property of the solid electrolyte particles, and electrical conductivity.

Abstract: A substrate processing method according to an embodiment includes a processing liquid supply step and an UV irradiation step. In the processing liquid supply step, a processing liquid is supplied to a substrate. In the UV irradiation step, the substrate after the processing liquid supply step is irradiated with ultraviolet rays having a wavelength of 200 nm or less, so that the substrate after the processing liquid supply step is destaticized.

Abstract: To provide a separator that has a strength preventing cracks from being formed in the production of a wound battery irrespective of a thin profile thereof, has high discharge rate characteristics, and has resistance to the formation of hydrofluoric acid due to the thermal decomposition of the electrolytic solution in high-temperature storage. A separator for a nonaqueous electrolyte secondary battery and a nonaqueous electrolyte secondary battery comprising the separator, wherein the separator comprising mainly glass fibers having added thereto MgO as an additive, the separator having a thickness of 45 ?m or less, a winding breakage strength of 1.2 kg or more, an anti-short-circuit strength of 1.0 kgf or more, and a separator resistance of 1.0 ohm or less.

Abstract: A substrate after being subjected to a dry etching processing is prepared. Then, an ultraviolet ray having a preset peak wavelength among multiple peak wavelengths is irradiated to the substrate based on a gas used in the dry etching processing.

Abstract: This invention provides an inorganic fiber paper that consists essentially of inorganic materials and has a basis weight of less than 100 g/m2 and has been mainly produced by a wet sheet making method. The inorganic fiber paper comprises inorganic fibers and an inorganic binder as materials, wherein the inorganic fibers have been bound to each other with the inorganic binder. In the inorganic fiber paper, the content of impurities during wet sheet making is low, the water resistance and flexibility are good, and satisfactory strength and high porosity can be realized.
