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： 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.
