    Abstract: A secondary battery with an exterior body having a novel sealing structure, and a structure of a sealing portion that relaxes a stress of deformation are provided. The secondary battery includes a positive electrode, a negative electrode, an electrolyte solution, and an exterior body enclosing at least part of the positive electrode, at least part of the negative electrode, and the electrolyte solution. The exterior body includes a first region having a shape with a curve, a shape with a wavy line, a shape with an arc, or a shape with a plurality of inflection points, and a second region having the same shape as the first region. The first region is in contact with the second region. Alternatively, the first region has a shape without a straight line. The secondary battery may be flexible, and the exterior body in a region having flexibility may include the first region.

    Abstract: The adhesion between metal foil serving as a current collector and a negative electrode active material is increased to enable long-term reliability. An electrode active material layer (including a negative electrode active material or a positive electrode active material) is formed over a base, a metal film is formed over the electrode active material layer by sputtering, and then the base and the electrode active material layer are separated at the interface therebetween; thus, an electrode is formed. The electrode active material particles in contact with the metal film are bonded by being covered with the metal film formed by the sputtering. The electrode active material is used for at least one of a pair of electrodes (a negative electrode or a positive electrode) in a lithium-ion secondary battery.
