The end cap according to an embodiment of the present application includes: a first recess recessed from the side of the end cap facing toward an electrode assembly in a direction away from the electrode assembly; a second recess recessed from the side of the end cap facing away from the electrode assembly of the battery cell in a direction toward the electrode assembly, wherein a bottom wall of the second recess includes a first part and a second part surrounding an outer side of the first part, and the first part and a bottom wall of the first recess are arranged opposite to each other in a thickness direction of the end cap; and a pressure relief portion formed between the first part and the bottom wall of the first recess, wherein the pressure relief portion is configured to be actuated, when an internal pressure of the battery cell reaches a threshold, to relieve the internal pressure, and the side of the second part facing away from the electrode assembly forms an avoidance space to avoid the pressure relief portion when the pressure relief portion is actuated. In the present application, the safety of the battery cell can be improved.",
