1. An electrode assembly, comprising:
a cylindrical main body part; and
a first tab and a second tab, wherein 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, the electrical conductivity of the first tab is X1, and the electrical conductivity of the second tab is X2, X2>X1,
wherein 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, an area of the first surface being larger than an area of the second surface,
wherein along a circumferential direction of the main body part, two ends of the first tab respectively form a first end face and a second end face, the first end face and the second end face are arranged opposite to each other, the first end face is connected to the first surface to form a first edge, the second end face is connected to the first surface to form a second edge, and the first edge is parallel to the second edge.
