SINTERED BODY, SOLID ELECTROLYTE THEREOF, ALL-SOLID-STATE LITHIUM ION BATTERY THEREOF, AND MANUFACTURING METHOD THEREOF
To provide a sintered body having a cubic garnet type structure lithium metal oxide sintered at a temperature of 900°C or lower capable of being integrally sintered with an electrode and excellent in ionic conductivity, a solid electrolyte using the sintered body, an all-solid-state lithium-ion battery, and a method for manufacturing the sintered body, the solid electrolyte, and the all-solid-state lithium-ion battery.SOLUTION: Disclosed is a sintered body which includes particles comprising a lithium metal oxide of a cubic garnet structure represented by Li7-aLa3 A2O12 where the parameter a satisfies 0≤a≤0.9, and the element A is at least one element selected from the group consisting of Zr, Ta, Hf, Sn, Nb, Ti, V, Bi, Mo, and W, and lithium hydroxide located at grain boundaries of the particles. A volume ratio of the lithium metal oxide to the total of the lithium metal oxide and lithium hydroxide is in the range of 50 vol% or more and 95 vol% or less.SELECTED DRAWING: Figure 1
