Abstract:
Disclosed is a method of preparing a solid electrolyte, which includes (a) preparing a solid electrolyte precursor slurry by subjecting a mixed solution including a metal precursor solution, containing a lanthanum precursor, a zirconium precursor and an aluminum precursor, a complexing agent, and a pH controller to coprecipitation, (b) preparing a solid electrolyte precursor by washing and drying the solid electrolyte precursor slurry, (c) preparing a mixture by mixing the solid electrolyte precursor with a lithium source, and (d) preparing an aluminum-doped lithium lanthanum zirconium oxide (LLZO) solid electrolyte by calcining the mixture, and which is also capable of adjusting the aluminum content of a starting material to thus control sintering properties and of adjusting the composition of a precursor and a lithium source to thus control the crystal structure, thereby improving the ionic conductivity of the solid electrolyte. In addition, a method of manufacturing an all-solid-state lithium secondary battery, including a solid electrolyte having improved ion conductivity, can be provided using the method of preparing the solid electrolyte.

Claim (Index 14):
The method of  claim 13 , wherein the lithium content of the lithium source in step (c) is 101 to 108 parts by weight based on 100 parts by weight of lithium of the solid electrolyte, which is the product of step (d).
