摘要： Disclosed are an all-solid battery and a method of manufacturing the same. The all-solid battery as disclosed herein may include current collectors having the same size for a cathode and an anode, the elongation areas of the cathode and the anode may be controlled due to the ductility of the current collectors during a pressing process. Thus, areas of the anode and the cathode may become different from each other upon the pressing, thus preventing a short-circuit fault from being formed at the edge portion thereof in the pressing process.

摘要： Disclosed are an all solid battery including a positive electrode layer including a positive electrode active material, a solid electrolyte and a conductive material coated with an insulator coating layer, an electrolyte layer, and a negative electrode layer and a method of manufacturing an all solid battery the same. In particular, the method includes: coating, by atomic layer deposition (ALD), a conductive material with an insulator by atomic layer deposition (ALD) to produce a conductive material surrounded by an insulator coating layer; producing a positive electrode layer including the conductive material coated with the insulator coating layer-formed conductive material, a positive electrode active material, and a solid electrolyte; and stacking and pressing the positive electrode layer produced above, an electrolyte layer and a negative electrode layer. The all solid battery can suppress side-reactions between the conductive material and the solid electrolyte, thereby advantageously maximizing energy density based on improved initial charge/discharge efficiency, and enhancing lifespan and power.

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.
