摘要： Provided are an anode for an all solid cell and a method of fabricating the same. The anode may include an anode current collector, a conductive material of which one end contacts a part of the anode current collector, a conductive coating layer surrounding the conductive material, an anode active material which contacts the other end of the conductive material, and a solid electrolyte. The conductive coating layer may prevent the conductive material and the solid electrolyte from being electrically connected to each other.

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： Disclosed is a method of manufacturing an all-solid state battery. The method includes coating a first slurry 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 slurry 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.

摘要： A fabrication method of an electrode for an all solid cell includes: providing a sulfide-based solid electrolyte; forming a coating layer on a surface of the sulfide-based solid electrolyte by heating a nonmetallic oxide at 300 to 700° C.; forming electrode slurry by mixing an electrode active material, the sulfide-based solid electrolyte formed with the coating layer, and a conductive material with a polar solvent; casting the electrode slurry on at least one surface of an electrode current collector; removing the polar solvent by heating the cast electrode slurry at 100 to 300° C.; and removing the coating layer by heating the electrode slurry from which the polar solvent is removed at 300 to 700° C.

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.
