摘要： Disclosed is a lithium ion-conductive sulfide-based solid electrolyte which includes nickel sulfide and, accordingly, the solid electrolyte can obtain a novel structure and performance.More particularly, the sulfide-based solid electrolyte includes lithium sulfide (Li2S), diphosphorus pentasulfide (P2S5), and nickel sulfide (Ni3S2) in a specific ratio by mol % and exhibits a novel crystal structure due to nickel (Ni). Accordingly, the sulfide-based solid electrolyte has greater lithium ion conductivity than an conventional sulfide-based solid electrolyte and a stable crystal structure.

摘要： Disclosed is a method of manufacturing a solid oxide fuel cell including a multi-layered electrolyte layer using a calendering process. The method for manufacturing a solid oxide fuel cell is a continuous process, thus providing high productivity and maximizing facility investment and processing costs. In addition, the solid oxide fuel cell manufactured by the method includes an anode that is free of interfacial defects and has a uniform packing structure, thereby advantageously greatly improving the production yield and power density. In addition, the solid oxide fuel cell has excellent interfacial bonding strength between respective layers included therein, and includes a multi-layered electrolyte layer in which the secondary phase at the interface is suppressed and which has increased density, thereby advantageously providing excellent output characteristics and long-term stability even at an intermediate operating temperature.

摘要： A method for preparing a sulfide-based solid electrolyte which is stable upon exposure to the air is provided. Specifically, a stabilization layer is formed on the surface of a sulfide-based solid electrolyte particle through treatment with a reactive gas.The sulfide-based solid electrolyte with superior air stability can be obtained because oxidation or reduction reactions with water, etc. in the air occur on the stabilization layer rather than on the sulfide-based solid electrolyte particle.

摘要： Provided is a method for manufacturing a sintered body for an electrolyte and an electrolyte for a fuel cell using the same. More particularly, the following disclosure relates to a method for preparing an electrolyte having a firm thin film layer by using a sintered body having controlled sintering characteristics, and application of the electrolyte to a solid oxide fuel cell. It is possible to control the sintering characteristics of a sintered body through a simple method, such as controlling the amounts of crude particles and nanoparticles. In addition, an electrode using the obtained sintered body having controlled sintering characteristics is effective for forming a firm thin film layer. Further, such an electrolyte having a firm thin film layer formed thereon inhibits combustion of fuel with oxygen when it is applied to a fuel cell, and thus shows significantly effective for improving the quality of a cell.
