  • SOLID ELECTROLYTE, METHOD OF PRODUCING SOLID ELECTROLYTE, AND BATTERY
    Publication number: 20230420734
    Abstract: A solid electrolyte is composed primarily of a component expressed by a composition formula of Lia+dMbXcAeOf by using values a to f that are greater than 0, where M is an element serving as a trivalent cation, X is a halogen element, and A is a sulfur element or a phosphorus element, wherein 0.8c?(a+3b)?1.2c and 1.6f?(d+n×e)?2.4f are satisfied, where when A is a sulfur element, n is 4 or 6, and when A is a phosphorus element, n is 5.

  • Lithium ion conductive material, all-solid-state secondary battery, and method of manufacturing solid electrolyte
    Patent number: 11575150
    Abstract: A lithium ion conductive material has a composition formula of Lia(OH)bFcCldBr1-d, where 1.8?a?2.3, b=a ?c?1, 0<c?0.30, 0<d<1, and includes an antiperovskite-type crystal phase. The lithium ion conductive material is manufactured, for example, by heating LiOH, LiF, LiCl, and LiBr at a temperature not lower than 250° C. and not higher than 600° C. for 0.1 hours or more while stirring them at a molar ratio of 1:X:Y:Z (where 0.03?X?0.3, 0.2?Y<1.1, 0<Z<1) under an Ar gas atmosphere.

  • Composite sintered body, semiconductor manufacturing apparatus member, and method of manufacturing composite sintered body
    Patent number: 11230502
    Abstract: The composite sintered body includes AlN and MgAl2O4. The open porosity of the composite sintered body is lower than 0.1%. The relative density of the composite sintered body is not lower than 99.5%. The total percentage of the AlN and the MgAl2O4 contained in the composite sintered body is not lower than 95 weight percentage and not higher than 100 weight percentage. The percentage of the MgAl2O4 contained in the composite sintered body is not lower than 15 weight percentage and not higher than 70 weight percentage. It is thereby possible to provide a high-density composite sintered body having high plasma corrosion resistance, high volume resistivity, and high thermal conductivity.
