発明の名称 (英語) ELECTROLYTE COMPOSITION, ELECTROLYTE FILM, AND CELL NEW
発明の概要(英語) [Problem] To provide: an electrolyte film having a practical film thickness, an excellent mechanical strength, and electrochemical characteristics; an electrolyte composition making it possible to obtain the electrolyte film; and a cell in which the electrolyte film is used.
[Solution] An electrolyte composition characterized in comprising an electrolyte powder, a binder, and an ion-conductive material; the electrolyte powder being an oxide-based ceramic electrolyte powder; the binder being a polymer compound that is stable with respect to metal ions; the ion-conductive material being a solvated ion-conductive material or an ion-conductive solution having a metal ion-based compound. An electrolyte film characterized in being provided with an electrolyte powder and a composite material in which a binder and an ion-conductive material are made into a composite.
従来技術、競合技術の概要(英語) BACKGROUND ART
The lithium secondary battery, long life, high efficiency, high capacity, a mobile phone, a notebook personal computer, such as a digital camera has been available for the power supply. The battery including an electrolyte film and is performed various investigations, and particularly the solid electrolyte has been developed. For example, to Patent Document 1, a composite metal oxide to the reaction with water can be prevented and, at the time of repeated charge and discharge cycle performance can be suppressed deterioration of solid electrolyte, Li and containing La and Zr and the lithium ion conductivity of the composite metal oxide having a garnet-type structure, the composite comprises lithium phosphate coating the surface of the metal oxide solid electrolyte membrane has been proposed. In addition, in Patent Document 2, the secondary battery, capacitor, as a material for solid electrolyte gas sensors, ultra-rapid cooling method using each of the components constituting the ions is present in the isolated ions with an ionic liquid and ion glass, additional mechanical energy at room temperature the mixture is a composite of, having a high ion conductivity and ion-conductive glass material has been proposed. Patent Document 3 is, due to volatilization of the electrolyte is not reduced, the long-term operational stability of the battery is safe as a solid electrolyte, the solid electrolyte is impregnated with an ionic liquid having a structure in which the lithium air battery has been proposed. In addition, in Patent Document 4, high safety, excellent charge-discharge cycle characteristics of the all-solid lithium secondary battery as an electrolyte membrane, the solid electrolyte powder and the powder compact has been formed, the gap between the powder of the powder compact, the metal reacts with the lithium and the resulting liquid to the electronic insulator material is present is the solid electrolyte layer has been proposed.
