摘要： A sulfide-based crystallized glass for an all-solid secondary battery has a sulfide that includes Li2S and P2S5, wherein the sulfide-based crystallized glass consists of 1 to 5% by mole of Li3BO3. A method for manufacturing the sulfide-based crystallized glass comprises steps of mixing (1) 75 to 80% by mole of Li2S and 20 to 25% by mole of P2S5, and then mixing (2) 95 to 99% by mole of obtained mixture at (1) and 1 to 5% by mole of Li3BO3 with a mechanical milling method, and subjecting the mixture thus obtained to a heat-treatment process.

摘要： A method for manufacturing a positive active material for an all-solid Lithium-Sulfur battery includes preparing a lithium sulfide solution by dissolving lithium sulfide in anhydrous ethanol. A mixture is prepared by mixing a carbon fiber to the lithium sulfide solution. A lithium sulfide-carbon fiber composite is prepared by drying the mixture of the carbon fiber and the lithium sulfide solution to deposit the lithium sulfide on a surface of the carbon fiber. The lithium sulfide-carbon fiber composite is heated at 400 to 600° C.

摘要： Disclosed is a method of manufacturing a crystallized glass for a secondary battery. The secondary battery include a solid electrolyte comprising sulfide, which can be prepared by synthesizing sulfides using thermal energy and vapor pressure as energy sources. The method of the present invention is suitable for manufacturing a crystallized glass for use as the electrolyte comprising sulfide of the secondary battery. The method includes dispersing two or more kinds of sulfides in a solvent and synthesizing the sulfides under conditions of a temperature equal to or greater than a boiling point of the solvent and high pressure greater than standard atmospheric pressure.
