摘要： Disclosed is a method of manufacturing a solid electrolyte for an all-solid battery. The method may include preparing a solvent admixture comprising a first polar organic solvent containing a cyano group and a second polar organic solvent containing a hydroxyl group, preparing an electrolyte admixture by dissolving Li2S, P2S5 and LiCl in the solvent admixture, and preparing a solid electrolyte by stirring the electrolyte admixture. The method may further include precipitating the solid electrolyte by evaporating the solvent admixture, and heat treating the precipitated solid electrolyte. In particular, the solvent admixture may include the second polar organic solvent in an amount of about 0.01 to 0.03 wt % based on the total weight of the first polar organic solvent.

摘要： A solid electrolyte sheet for all-solid batteries has a carrier film including poly (methyl methacrylate) and an ionic conductive material, and has a solid electrolyte slurry coated on the carrier film. The solid electrolyte sheet and an all-solid battery including such a solid electrolyte sheet can realize formation of a solid electrolyte layer as a thin film and can prevent a short-circuit upon stacking a positive electrode and a negative electrode. The solid electrolyte sheet and the all-solid battery can prevent yield decrease resulting from a short-circuit of the all-solid battery and can minimize supernumerary pores due to ionic conductive material incorporated into the solid electrolyte layer to suppress formation of lithium dendrites.
