摘要： The present disclosure relates to garnet powder, a manufacturing method thereof, a solid electrolyte sheet using a hot press, and a manufacturing method thereof. In particular, the present disclosure provides a method for manufacturing Li7La3Zr2O12 (LLZ) garnet powder including preparing a mixture by first dry mixing Li2CO3, La2O3, ZrO2, and Al2O3. The mixture is first calcinated for 5 to 7 hours in a temperature range of 800 to 1000° C. The calcinated mixture is ground to a powder with an average particle size of 1 to 4 μm through dry grinding. A cubic-phased LLZ garnet powder is prepared by second calcinating the ground mixture for 10 to 30 hours in a temperature range of 1100 to 1300° C.

摘要： Disclosed is a lithium ion-conductive sulfide-based solid electrolyte which includes nickel sulfide and, accordingly, the solid electrolyte can obtain a novel structure and performance.More particularly, the sulfide-based solid electrolyte includes lithium sulfide (Li2S), diphosphorus pentasulfide (P2S5), and nickel sulfide (Ni3S2) in a specific ratio by mol % and exhibits a novel crystal structure due to nickel (Ni). Accordingly, the sulfide-based solid electrolyte has greater lithium ion conductivity than an conventional sulfide-based solid electrolyte and a stable crystal structure.

摘要： Disclosed is a nonvolatile electrolyte and a method for manufacturing a dye sensitized solar cell using the nonvolatile electrolyte. In particular, the electrolyte may maintain stability during a durability test of a solar cell module. Moreover, sealing breakage of a module occurring in the related arts may be prevented, and ion mobility may be improved thereby improving efficiency.

摘要： Disclosed are a dye-sensitized solar cell module and a method of manufacturing the same. The dye-sensitized solar cell module includes a working electrode formed by stacking a collector and a photo-electrode to which a dye is adsorbed on a transparent conductive substrate; a counter electrode formed by stacking a collector and a catalytic electrode on a transparent conductive substrate; and an electrolyte filled in a space between the working electrode and the counter electrode sealed by a sealant. A glass substrate for the working electrode of glass substrates forming the transparent conductive substrates for the electrodes is a thin glass plate substrate thinner than the glass substrate for the working electrode.

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 method of manufacturing a sulfide-based solid electrolyte through a wet process is provided. The method includes preparing a slurry by adding a solvent to a mixture including lithium sulfide and a sulfide of a group 14 or group 15 element and amorphizing the mixture by milling the slurry. The slurry is dried in order to remove the solvent. The dried mixture is crystallized by heat-treating to form the sulfide-based solid electrolyte.
