    摘要: The present application discloses a battery to reduce a height of an edgefold protrusion in a direction perpendicular to a top seal, reduce structural interference between the edgefold protrusion and other components and parts, and improve a structural compactness when a user utilizes the battery. The battery includes a cell, a packaging bag, and an electrode tab. The packaging bag includes a first packaging portion configured to accommodate the cell and a second packaging portion configured to seal the cell. The second packaging portion includes a top seal configured to seal the electrode tab and two side seals intersecting the top seal. A notched structure is formed at an intersection of the top seal and the side seal. The side seal is folded over along an edge of the side seal adjacent to the first packaging portion and fixed to an outer side surface of the first packaging portion.
