摘要： The present disclosure relates to garnet powder, a manufacturing method thereof, a solid electrolyte sheet using a hot press, and a manufacturing method thereof. In particular, the present disclosure provides a method for manufacturing Li7La3Zr2O12 (LLZ) garnet powder including preparing a mixture by first dry mixing Li2CO3, La2O3, ZrO2, and Al2O3. The mixture is first calcinated for 5 to 7 hours in a temperature range of 800 to 1000° C. The calcinated mixture is ground to a powder with an average particle size of 1 to 4 μm through dry grinding. A cubic-phased LLZ garnet powder is prepared by second calcinating the ground mixture for 10 to 30 hours in a temperature range of 1100 to 1300° C.

摘要： A method of manufacturing a sulfide-based solid electrolyte through a wet process is provided. The method includes preparing a slurry by adding a solvent to a mixture including lithium sulfide and a sulfide of a group 14 or group 15 element and amorphizing the mixture by milling the slurry. The slurry is dried in order to remove the solvent. The dried mixture is crystallized by heat-treating to form the sulfide-based solid electrolyte.
