摘要： Disclosed are an all-solid-state battery having high energy density and a method for manufacturing the same. One battery structure is pressed instead of pressing each cell unit, an amount of first or second electrode current collectors consumed is reduced, and insulating members are used, thereby simplifying a manufacturing process of the all-solid-state battery and allowing the all-solid-state battery to have high energy density and a stable structure.

摘要： The present disclosure relates to a method of manufacturing a cathode composite for an all-solid-state battery and a method of manufacturing an all-solid-state battery including the same. In particular, the present disclosure relates to a method of manufacturing a cathode composite for an all-solid-state battery in which the cathode composite is manufactured by mixing a solid electrolyte, a conductive material and a cathode active material with a solvent, and then performing two-step vacuum drying, whereby interfacial resistance between the cathode active material, the solid electrolyte and the conductive material is reduced to thus increase ionic conductivity, thereby improving battery performance and capacity, and a method of manufacturing an all-solid-state battery including the same.

摘要： Disclosed are a method of manufacturing a solid electrolyte, a solid electrolyte manufactured using the method, and an all-solid cell including the solid electrolyte. The method includes preparing an electrolyte admixture including a solid electrolyte precursor and a solvent, drying the electrolyte admixture and removing the solvent from the electrolyte admixture to form a dry electrolyte mixture, and heat-treating the dry electrolyte mixture to form a crystallized solid electrolyte.

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： 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.
