Abstract

A battery cell includes a battery cell body, at least two tabs, a first connector and at least two insulators. The first connector is configured to fasten a tail end of an electrode assembly to an outer surface of the battery cell body; the at least two tabs include a first tab and a second tab, and the at least two insulators include a first insulator and a second insulator, where first ends of the first insulator and the second insulator are all provided on the battery cell body, a second end of the first insulator covers part of the first tab, and a second end of the second insulator covers part of the second tab; and in a width direction of the battery cell body, the first insulator is provided close to the first connector, where at least part of the first insulator is located outside the first connector.
