The cylindrical battery cell comprises: a housing having openings; and electrode assemblies provided in the housing. Each electrode assembly comprises a diaphragm and a tab; in the axial direction of the electrode assembly, the tab is located at one end of the electrode assembly and extends towards the opening; the tab comprises a first portion and a second portion; the second portion surrounds the periphery of the first portion; the diaphragm wraps the second portion to isolate the second portion from the housing, wherein in the axial direction, the first portion exceeds the second portion and the diaphragm, and the second portion does not exceed the diaphragm. The battery cell of the present application aims at solving the technical problem of short circuit of the battery cell.",
