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

The invention provides a pole piece, an electrode assembly, a battery monomer, a battery and electric equipment, and relates to the technical field of batteries. The pole piece comprises a positive active layer, a first current collecting layer, an insulating layer, a second current collecting layer and a negative active layer which are stacked in the first direction, the insulating layer is arranged between the first current collecting layer and the second current collecting layer, the positive active layer is arranged on the surface, away from the insulating layer, of the first current collecting layer, and the negative active layer is arranged on the surface, away from the insulating layer, of the second current collecting layer. After a plurality of pole pieces are stacked along the first direction to form the electrode assembly, the first current collectors of the pole pieces are conductively connected, and the second current collectors of the pole pieces are conductively connected, so that the internal parallel electrode assembly is formed, the internal resistance of the battery with the electrode assembly is reduced, the current in the charging process of the battery is increased, and the charging efficiency of the battery is improved. Therefore, the charging rate of the single battery and the battery is improved.
