The housing is provided with a terminal. The electrode assembly is arranged in the housing, and includes an active material coating portion and a tab. The tab and the terminal are connected through welding to form a weld mark. The weld mark includes a first weld and a second weld. The second weld is located on a side of the first weld in a width direction of the first weld and partially overlaps with the first weld. A maximum thickness of the first weld is less than a maximum thickness of the second weld. In the technical solution of embodiments of the present application, the first weld is formed on a side of the second weld in a width direction of the second weld.",
