摘要： Disclosed is a method for analyzing a sulfide-based solid electrolyte using computer simulation including connecting, by a user, to a client accessible to a server, inputting information of a sulfide-based solid electrolyte to be analyzed to the client, transmitting, by the client, the information to the server, implementing, by the server, generation of a three-dimensional structure in which anion clusters and lithium ions are disposed, based on the transmitted information, feeding back, by the server, an implementation result to the client, and displaying, by the client, the feedback result. In addition, properties of sulfide-based solid electrolytes, which cannot be observed by experimentation, can be analyzed based on lithium, ion conductivity.

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： Disclosed is a cathode active material having a core-shell structure. The core-shell cathode active material includes a core including a lithium transition metal oxide with excellent electrochemical properties and a shell formed by coating the surface of the core with a transition metal oxide. The formation of the shell by coating a transition metal oxide on the surface of the core comprising a lithium transition metal oxide prevents the structure of the lithium transition metal oxide from collapsing and inhibits the dissolution of manganese ions, enabling the fabrication of a hybrid capacitor with improved energy density and rate characteristics. Also disclosed is a method for producing the cathode active material.

摘要： Disclosed are a lithium ion-conducting sulfide-based solid electrolyte containing selenium and a method for preparing the same. More specifically, disclosed is a lithium ion-conducting sulfide-based solid electrolyte containing selenium that is capable of significantly improving lithium ion conductivity by successfully replacing a sulfur (S) element with a selenium (Se) element, while maintaining an argyrodite-type crystal structure of a sulfide-based solid electrolyte represented by Li6PS5Cl.
