Abstract

The present application provides an electrode assembly, a battery cell, a battery and an electrical apparatus, belonging to the technical field of batteries. The electrode assembly includes a main body part, a first tab and a second tab. The main body part is cylindrical. The polarities of the first tab and the second tab are opposite, the first tab and the second tab are arranged at the same end of the main body part along an axial direction of the main body part, and the electrical conductivity of the first tab is smaller than the electrical conductivity of the second tab. Along the axial direction of the main body part, the first tab has a first surface away from the main body part, and the second tab has a second surface away from the main body part, the area of the first surface being larger than the area of the second surface. By setting the area of the first surface of the first tab to be larger than the area of the second surface of the second tab, it is convenient to distinguish and identify the first tab and the second tab with different polarities during the assembly of a battery cell, and the electrode assembly can be assembled without secondary positioning, thereby being conducive to reducing the difficulty in the subsequent assembly of the electrode assembly.
