Abstract

The present application relates to the field of batteries. Provided are a battery cell, a battery and an electric device. The battery cell comprises a casing and an electrode assembly, wherein the electrode assembly is accommodated in the casing. The electrode assembly comprises a body portion, a first tab and a second tab, wherein the first tab and the second tab respectively protrude from two ends of the body portion, and the first tab and the second tab are asymmetrically arranged. The first tab and the second tab of the battery cell are asymmetrically arranged; and compared with the solution in the prior art where two tabs of a battery cell are symmetrically arranged, the first tab and the second tab of the electrode assembly of the battery cell have no axis of symmetry, and the first tab and the second tab are stressed unevenly, such that the electrode assembly does not easily rotate, and thus the first tab and the second tab are not easily torn, thereby facilitating the prolonging of the service life of the battery cell.
