Abstract: This application discloses a housing, a battery cell, a battery, and an electric device, and pertains to the field of battery technologies. The housing has at least three edge portions intersecting at a same vertex. An indentation groove is provided on the housing, and the indentation groove intersects with at least two of the edge portions. Because the region near the edge portion of the housing has strong deformation resistance, the probability of abnormal cracking of the indentation groove due to creeping of the region in which the indentation groove is provided on the housing is reduced, thereby prolonging service life of the battery cell.
