Abstract
An all solid electrode structure having a solid electrolyte concentration gradient is provided and a method of improving an output performance is provided with improved ion diffusion and obtaining a high capacity battery, by disposing an anode or cathode electrode having a substantially continuous concentration gradient to have a greater solid electrolyte ratio as being closer to a solid electrolyte interface and have a greater active material ratio as being close to a current collector interface. The active material/solid electrolyte ratio of anode and cathode active material layers has a concentration gradient by a single process using an aerosol deposition method.
