Abstract

The present application provides a battery cell (20), a battery (100), and a power consuming apparatus, belonging to the field of battery technologies. The battery cell (20) includes a first electrode sheet (231), separators (233), and a plurality of second electrode sheets (232). The first electrode sheet (231) is provided with a plurality of structurally weakened areas (234) extending in a width direction of the first electrode sheet (231). The separators (233) cover surfaces on two opposite sides of the first electrode sheet (231). The plurality of second electrode sheets (232) are alternately arranged on the separators (233) on the two opposite sides of the first electrode sheet (231). Every two adjacent second electrode sheets (232) are located on different sides of the first electrode sheet (231) in a length direction of the first electrode sheet (231), and one corresponding structurally weakened area (234) is present between every two adjacent second electrode sheets (232). The first electrode sheet (231) is folded at the plurality of structurally weakened areas (234), so that the first electrode sheet (231) and the plurality of second electrode sheets (232) are alternately stacked with each other.
