Abstract:
1. A method for preparing an electrochemical device comprising: laminating a first current collector, a first electrode active material layer, a solid electrolyte layer, a second electrode active material layer and a second current collector, wherein said first electrode active material layer or said second electrode active material layer is formed on a surface of said solid electrolyte layer as a substrate by film formation comprising vapor-depositing atoms, ions or clusters constituting said first electrode active material layer or said second electrode active material layer, wherein said film formation further comprises irradiating said atoms, ions or clusters constituting said first electrode active material layer or said second electrode active material layer with energy having a strength E (eV) that satisfies a relational expression: wherein: −7≦α≦7, E ρ and d wherein said energy is carried only by electrons to be irradiated to a surface of said substrate on which said first electrode active material layer or said second electrode active material layer is to be formed.
