摘要： A solid electrolyte sheet for all-solid batteries has a carrier film including poly (methyl methacrylate) and an ionic conductive material, and has a solid electrolyte slurry coated on the carrier film. The solid electrolyte sheet and an all-solid battery including such a solid electrolyte sheet can realize formation of a solid electrolyte layer as a thin film and can prevent a short-circuit upon stacking a positive electrode and a negative electrode. The solid electrolyte sheet and the all-solid battery can prevent yield decrease resulting from a short-circuit of the all-solid battery and can minimize supernumerary pores due to ionic conductive material incorporated into the solid electrolyte layer to suppress formation of lithium dendrites.

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.

摘要： Disclosed is a method of manufacturing an all-solid state battery. The method includes coating a first slung or composition having on a substrate to form a first electrolyte layer a predetermined thickness, coating a second slurry or composition on the first electrolyte layer to form a second electrolyte layer having a predetermined thickness, laminating an electrode layer on the second electrolyte layer, bonding the electrode layer to the second electrolyte layer through pressing, and removing the substrate from the first electrolyte layer. The first slung or composition of the first electrolyte layer has content of a binder less than that of the second slurry or composition of the second electrolyte layer, and thus, the substrate may be easily removed from the first electrolyte layer.

摘要： Disclosed is a method of manufacturing a solid electrolyte for an all-solid battery. The method may include preparing a solvent admixture comprising a first polar organic solvent containing a cyano group and a second polar organic solvent containing a hydroxyl group, preparing an electrolyte admixture by dissolving Li2S, P2S5 and LiCl in the solvent admixture, and preparing a solid electrolyte by stirring the electrolyte admixture. The method may further include precipitating the solid electrolyte by evaporating the solvent admixture, and heat treating the precipitated solid electrolyte. In particular, the solvent admixture may include the second polar organic solvent in an amount of about 0.01 to 0.03 wt % based on the total weight of the first polar organic solvent.
