Abstract: The embodiments of the present application provide a battery cell, a battery and a power consuming device, which fall within the technical field of batteries. The battery cell includes an electrode assembly and a shell. The shell accommodates the electrode assembly, and includes a wall portion that is arranged opposite the electrode assembly in a thickness direction of the wall portion. The wall portion is provided with a first reinforcement portion in a protruding manner, the first reinforcement portion extends in a circumferential direction of the wall portion, the wall portion includes a first region located on an outer circumferential side of the first reinforcement portion, and a weak portion is formed in the first region and is configured to rupture during pressure relief of the battery cell. The first reinforcement portion has an effect of reinforcing the wall portion to strengthen the weak portion.
