  "textContent": "The present application provides a battery cell, a battery, an electric apparatus, a manufacturing method and apparatus of a battery cell. Where the battery cell includes an electrode assembly, a pressure relief mechanism, and an end cover. A concave part on the end cover is recessed from one side, away from the electrode assembly, of the end cover, and the concave part is configured to accommodate at least a part of the pressure relief mechanism. The pressure relief mechanism covers the first welding part in a thickness direction of the end cover, and the dimension of the pressure relief mechanism in the direction perpendicular to the thickness direction of the end cover would not be limited by the first welding part, thus the dimensions of the concave part and the pressure relief mechanism may be appropriately increased to improve the pressure relief capacity of the pressure relief mechanism.",
