  • Publication number: 20170338517
    Abstract: An all solid-state battery is formed of slurry of an electrode/electrolyte/conductive material composite. An outer circumferential surface of the conductive material is coated with a solid electrolyte to form a solid electrolyte layer. Since the surface of the conductive material is coated with a solid electrolyte, contact characteristics between the conductive material and the solid electrolyte and between the conductive material and an electrode can be maximized. Also, since the surface of the conductive material having a large surface area is coated with the solid electrolyte, an ion conductor, the conductive material may be given ion conductivity, as well as electronic conductivity, facilitating securing of an ion conduction path. In addition, since the conductive material having a large surface area is coated with the solid electrolyte, a proportion of the solid electrolyte to the composite may be reduced.

  • Publication number: 20170214051
    Abstract: Provided is an electrode active material slurry including a clustered complex and a slurry, wherein the clustered complex includes an electrode active material, a solid electrolyte, a conductive material, and a first binder, and the slurry includes a solvent and a second binder. The electrode active material slurry may include the clustered complex including the first binder and the slurry including the second binder so as to decrease a surface area of the overall complex, such that adhesion property with the current collector may be sufficiently secured even by using a small amount of binder, and performance of the all-solid secondary battery may be further improved.

  • Publication number: 20170166471
    Abstract: 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.

  • Publication number: 20170133710
    Abstract: 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.
