The shell accommodates the electrode assembly, and a side of the shell close to an opening includes a rolling groove recessed toward an interior of the shell. The current collecting component is disposed between the rolling groove and the electrode assembly and includes a current collecting body and a connecting sheet connected to the current collecting body. The current collecting body is connected to the electrode assembly. The connecting sheet bends toward a center of the current collecting body and is welded to the rolling groove, thereby forming a first welding mark. The connecting sheet includes a bending portion located between the first welding mark and the current collecting body. A side of the bending portion is provided with a first weak portion.",
