  "textContent": "Embodiments of the present application provide a battery cell, a battery, an electrical device, and a method and a device for manufacturing the battery cell, which belong to the technical field of batteries. A battery cell comprises an electrode assembly, a housing, and an end cap. The electrode assembly has a first tab. The housing has an opening and a first limit part, and the housing is used for accommodating the electrode assembly. The end cap comprises a cap body, and the cap body is used to cover the opening. In the thickness direction of the end cap, the cap body is located on one side of the first limit part away from the electrode assembly, and the first limit part is used to limit the cap body from moving relatively to the housing towards the electrode assembly. The end cap further comprises a first convex part which protrudes from the inner surface of the cap body towards the electrode assembly, and the first convex part is configured to go beyond the first limit part away from the cap body, so that the first convex part is pressed against the first tab, ensuring the good contact between the first convex part and the first tab, reducing the risk that the first tab cannot be in contact with the end cap due to the limitation of the first limit part, and ensuring battery performance.",
