ELECTRODE STRUCTURE AND ALL-SOLID-STATE SECONDARY BATTERY INCLUDING THE SAME

An electrode structure (100) and an all-solid-state secondary battery (1000), the electrode structure (100) includes an anode current collector (10) having first and second surfaces (15, 16), the first surface (15) including first and second portions (10a, 10b), and a middle portion (10c) between the first and second portions (10a, 10b), the first and second portions (10a, 10b) being oriented to face outwardly in opposite directions with the middle portion (10c) therebetween, and the anode current collector (10) being folded such that the second surface (16) faces inwardly in the anode current collector (10); first and second anode plate layers (21, 22) on the first surface (10a); first and solid electrolyte layers (31, 32) on outer sides of the first and second anode plate layers (21, 22); first and second cathode plate layers (41, 42) on outer sides of the first and second solid electrolyte layers (31, 32); and an elastic sheet (60) inside an interior space of the folded anode current collector (10).
