発明の名称 (英語) SOLID ELECTROLYTE FOR ALL-SOLID-STATE SODIUM BATTERY, MANUFACTURING METHOD THEREFOR, AND ALL-SOLID-STATE SODIUM BATTERY
発明の概要(英語) A solid electrolyte for an all-solid-state sodium battery represented by the formula Na3-xSb1-xαxS4 (in the formula, α is selected from among elements in which Na3-xSb1-x αxS4 exhibits a higher ion conductivity than Na3SbS4, and x is 0<x<1).
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, electric vehicles, hybrid vehicles and the like of the vehicle, the solar cell, such as wind power generation apparatus or the like, to store the power demand of a lithium ion battery is increased. However, the lithium-ion battery, a small amount of deposits, and the output destination in order to use the lithium is unevenly distributed, instead of lithium, sodium-rich amount of resources has been proposed to use. Further, from the viewpoint of securing safety, without the use of liquid electrolyte, solid electrolyte is used in the all-solid sodium battery has been actively studied. Is a solid electrolyte, the all-solid sodium battery discharge capacity from the viewpoint of improving physical properties such as, higher ionic conductivity has been demanded. In particular all-solid-state sodium secondary battery, charge and discharge capacity, from the viewpoint of improving the physical properties of the cycle numbers, the higher the ionic conductivity of solid electrolyte which has been obtained. Non-Patent Document 1, A. Banerjee et al., Angew. Chem. Int. Ed., 55 (2016) 9634.(from this point of view) and H. Wang et al., Angew. Chem. Int. Ed., 55 (2016) 9551.(Non-Patent Document 2) is, Na3SbS4 indicates a high ionic conductivity, in addition, the atmosphere stability have been reported.
