A battery cell includes an electrode assembly, a case, an end cover assembly, and a current collecting component. The electrode assembly includes a first tab. The case is used for accommodating the electrode assembly, and the case has an opening. The end cover assembly covers the opening and is provided with an electrode lead-out portion. The current collecting component includes a tab connecting region and an end cover connecting region. The tab connecting region is used for connecting to the first tab. The end cover connecting region is welded to the inner side of the electrode lead-out portion and forms a first welded portion. The penetration depth of the first welded portion formed on the electrode lead-out portion is smaller than or equal to the thickness of the electrode lead-out portion.
