Abstract
Provided is a method for preparing a needle-like sulfide-based solid electrolyte. The method may include: preparing a solid electrolyte admixture comprising an organic solvent, LiS, PS, and LiCl; synthesizing a solid electrolyte by stirring the solid electrolyte admixture at a temperature of about 30 to 60° C. for about 22 to 26 hours; first stirring the solid electrolyte at a speed of about 80 to 120 rpm for about 5 to 10 minutes; after the first stirring, second stirring the first stirred solid electrolyte at a speed of about 250 to 300 rpm; vacuum-drying the second stirred solid electrolyte for about 12 to 24 hours; and heat-treating the vacuum-dried solid electrolyte at a temperature of about 350 to 550° C. for about 1 to 5 hours.
