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： 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： A method of manufacturing a short-preventive all-solid-state battery in which a thermosetting insulating resin applied in advance to a pouch-type electrode case provided with an electrode assembly received therein is forced to fill a space between the edges of the electrode assembly during packaging of the electrode assembly to fill vacant spaces between electrodes at the edges of the electrode assembly and may thus prevent physical contact and collision between the electrodes and fundamentally prevent generation of a short circuit caused thereby.

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.
