Abstract: A battery cell includes a housing having an opening at an end along a first direction, an electrode assembly contained in the housing and having a main body and a tab connected to the main body, and an end cap configured for covering the opening. The housing includes a first side plate having a first plate portion and a second plate portion both arranged along the first direction. The second plate portion is located at an end of the first plate portion near the opening, and a thickness of the second plate portion is greater than a thickness of the first plate portion. An end of the second plate portion near the first plate portion extends beyond the welded portion in the first direction. The main body does not overlap with the second plate portion in a thickness direction for the first side plate.
