Abstract: A battery cell, a battery, a power consuming device, and a method for manufacturing a battery cell are provided. The battery cell includes: a shell; and an electrode assembly arranged in the shell and including a first electrode plate and a second electrode plate having an opposite polarity to the first electrode plate. The first electrode plate is repeatedly folded in a first direction such that the first electrode plate comprises a plurality of first stack sections connected and stacked in sequence, and the second electrode plate is folded once in a second direction such that the second electrode plate comprises two second stack sections connected to each other, the second direction being perpendicular or parallel to the first direction. The second stack sections and the first stack sections are stacked alternately in sequence. A bent portion of the second electrode plate is in contact with an inner wall of the shell.
