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 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.
