摘要: 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, Li2S, P2S5, 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.

摘要: An improved, low porosity, solid electrolyte membrane and a method of manufacturing the solid electrolyte membrane are provided. The low porosity, solid electrolyte membrane significantly improves both mechanical strength and porosity of the membrane, inhibits the growth of lithium dendrites (Li dendrites), and thereby maintains and maximizes electrochemical stability of an all-solid-state battery. This is accomplished by wet-coating a sulfide or oxide solid electrolyte particle with a thermoplastic resin, or a mixture of the thermoplastic resin and a thermosetting resin, using a solvent to prepare a composite and hot-pressing the composite at a relatively low temperature and at a low pressure.

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.

摘要: Disclosed is a method of manufacturing an all-solid state battery. The method includes coating a first slung or composition having on a substrate to form a first electrolyte layer a predetermined thickness, coating a second slurry or composition on the first electrolyte layer to form a second electrolyte layer having a predetermined thickness, laminating an electrode layer on the second electrolyte layer, bonding the electrode layer to the second electrolyte layer through pressing, and removing the substrate from the first electrolyte layer. The first slung or composition of the first electrolyte layer has content of a binder less than that of the second slurry or composition of the second electrolyte layer, and thus, the substrate may be easily removed from the first electrolyte layer.
