Zusammenfassung:	The present application belongs to the technical field of batteries. Provided are a laminated electrode assembly, a battery cell, a battery, and an electric apparatus. The laminated electrode assembly comprises a first electrode sheet and a second electrode sheet, which have opposite polarities, wherein the first electrode sheet and the second electrode sheet are arranged in a stacked manner in a first direction. The first electrode sheet comprises a first coating area and a first blank area, which are arranged in a second direction, wherein the first blank area comprises a first connecting portion and a first tab portion; the first connecting portion is connected to the first coating area and the first tab portion; in a third direction, the size of the first connecting portion is greater than the size of the first tab portion; and the first direction, the second direction and the third direction are perpendicular to each other in a pairwise manner. The first connecting portions of a plurality of first electr
