Abstract:
A repeatedly bendable power storage device. A highly reliable power storage device. A long-life power storage device. A repeatedly bendable electronic device. A flexible electronic device. The power storage device includes a film, a positive electrode, and a negative electrode. The film includes a plurality of projections. A difference between the maximum height and the minimum height of a surface of the film is greater than or equal to 0.15 mm and less than 0.8 mm. The modulus of rigidity of the film is less than 6.5×109 N. The film includes a metal layer. The thickness of the metal layer is greater than or equal to 5 μm and less than or equal to 200 μm. The positive electrode and the negative electrode are surrounded by the film.
