METHOD OF MANUFACTURING A CRYSTALLIZED GLASS FOR SECONDARY BATTERY AND AN ELECTRODE COMPRISING SULFIDE

Disclosed is a method of manufacturing a crystallized glass for a secondary battery. The secondary batter 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.
