Pole piece, battery monomer, electrode assembly, battery and electric equipment

The utility model discloses a pole piece, a battery monomer, an electrode assembly, a battery and electric equipment, and belongs to the technical field of batteries. The pole piece comprises a current collector, the current collector comprises a main body and a plurality of tabs, the main body is provided with a first edge in the width direction, the tabs protrude from the first edge, and the tabs are arranged at intervals in the length direction of the main body. Wherein the plurality of tabs comprise at least one first tab, the first tab comprises a first sub-tab and a second sub-tab, and a gap is formed between the first sub-tab and the second sub-tab. The bending strength of the first tab is weakened, so that the bending difficulty of the first tab is reduced, meanwhile, the risk of excessive deformation of the main body caused by overlarge external force required by bending when the first tab is bent is reduced, and the safety of the single battery is improved. 本申请公开了一种极片、电池单体、电极组件、电池及用电设备，属于电池技术领域。极片包括
