In a solid electrolyte obtained by sintering a powder, high ionic conductivity and remarkably low moisture permeation applicable to a lithium ion secondary battery or a lithium primary battery are realized. A method for producing a solid electrolyte including the steps of preparing a green sheet containing a lithium ion conductive inorganic material powder; and firing the green sheet, wherein in the step of firing the green sheet, at least one surface of the green sheet is covered by a setter having a porosity of not more than 10% by volume, is disclosed.

By measuring ultralow moisture permeation through a barrier material sample at a temperature substantially above ambient, definitive values are produced on an accelerated basis that can be used to accurately predict long term daily performance of that barrier material. The sample is heated to a desired test temperature where there is controlled access to both its upstream and downstream surfaces, and HTO vapor is then supplied at predetermined relative humidity to the upstream surface by fracturing a glass ampoule containing not more than 10 millicuries of specific radioactivity for each test. Radioactive gas permeating from the downstream surface is collected by circulating a very slow flow of dry carrier gas past the downstream surface, which stream flows to an ionization chamber containing a beta-particle radiation monitor. Continuous monitoring generates signals that are converted to calculate instantaneous permeation rates through the sample, and operation at such elevated temperature is carried out until the values being monitored reach a steady state, allowing accurate prediction of the extent of long term barrier protection against moisture permeation the sample will exhibit.

The invention discloses aerogel composite cloth taking a hot melt adhesive as a binder and a preparation method for the aerogel composite cloth. The composite cloth takes a fiber enhanced aerogel material as a core layer, and a layer of fabric covers each of the upper part and the lower part of the core layer; the hot melt adhesive serving as the binder is arranged between the core layer and the fabrics. Sticky glue of the fiber enhanced aerogel material is cleaned and swept; after the hot melt adhesive covers the upper part and the lower part of the fiber enhanced aerogel material, the hot melt adhesive is respectively covered with layers of cloth; the aerogel composite cloth is cut and packaged after being pressurized by a hot roller. The aerogel composite cloth disclosed by the invention has the advantages of excellent heat insulation performance, high moisture permeation property, high softness, no dust escape and the like, and can be applied to a cold-resistant or fireproof tent, a sleeping bag, a floor mat, shoes, shoe insoles, cloths and hats as well as internal heat insulation decorations of automobiles, airplanes, ships and trains; the application field of the aerogel composite cloth is greatly expanded; furthermore, the technology is simple, the quality is easy to control, and the aerogel composite cloth is suitable for batch production.

The invention provides a manufacturing method for a flexible OLED and the flexible OLED. The manufacturing method for the flexible OLED comprises the following steps of: by taking a magnetic substrate as a carrier base plate, fixing a flexible magnetic film on the magnetic substrate through magnetic adsorption, forming a polymer film on the flexible magnetic film, manufacturing an OLED device on the polymer film, and encapsulating the OLED device, thereby manufacturing the flexible OLED. The manufacturing method is simple, by demagnetizing the magnetic substrate, lossless separation of the flexible magnetic film and the magnetic substrate can be achieved; in addition, the flexible magnetic film is optionally a metal film with good moisture blocking properties, moisture permeation rate can be reduced, and the stability of the OLED device can be improved. By encapsulating the OLED device, the reliability of the properties of the OLED device is further improved. The flexible OLED provided by the invention is simple in manufacturing process and excellent in property.
